(10) Canon Ef-m 32mm F/14 Stm Lens Review

The newest generation of photographic camera sensors has made it possible to capture stunning night sky photography

Astrophotography sounds technical, but it'southward merely a landscape where you want the stars to exist included. The all-time images tend to combine some distinctive foreground landscape with the star-filled sky above.

The Canon EOS 1000 mirrorless camera bodies are excellent for getting started in astrophotography.

Their sensors choice up superb detail, only the trick is to get abroad from city lights and mount the best lens for the chore.

Here'due south a look at the seven best EF-M lenses for astrophotography:

The new generation of Sigma lenses has been blowing photographers away no matter what their specialty is.

The Contemporary lineup is a group of high-performance lenses for APS-C sensor cameras similar the EOS-M family.

With a fast f/1.4 aperture, this lens blows away every other lens on my list.

At just nether 26 mm in 35 mm terms, the focal length is a bit higher than what I would normally use for wide-angle astrophotography, though.

The biggest thing that this lens has going for information technology is its multifunctionality. Since information technology's a fully electronic lens with autofocus and exposure settings, you lot're far more than probable to utilise this wide-angle for many other things.

It's a dandy size for general landscapes and even equally a walkaround travel lens. And since it'due south custom-built for a cropped sensor camera, this Sigma DC lens is smaller, lighter, and cheaper than most other f/1.4 lenses on the marketplace.

The Sigma's eyes are also commencement-class, with industry-leading low dispersion elements to reduce chromatic aberrations and ghosting.

Their Super Multi-Layer Coatings also reduce flare, a great characteristic if the moon or other bright object is in your epitome.

When information technology comes to astrophotography, I like to have a super-wide-bending prime number on manus. Rokinon's have been my go-to lenses for a few years for this purpose.

Their prototype quality is always surprising for their price point.

There are certainly sharper lenses out at that place, simply Rokinon has built a stellar reputation among star photographers.

They are fast, and they are wide. And since nigh of them are fully manual, you tin can salve a picayune money over the electronic versions.

If 10 mm is a picayune too much, there is the slightly faster Rokinon 12mm f/2.0.

Choosing between the two is most impossible, but remember the APS-C crop cistron of one.6x makes the two mm focal length difference larger than you might at get-go realize.

In the finish, both are broad, fast, rectilinear lenses that are perfect for astrophotography if you desire an inexpensive manual lens.

If you already own the Canon EOS Yard adapter to use EF-mount lenses, in that location are a few other lenses worth checking out.

The adjacent generation of Samyang lenses, dubbed the XP line, feature the same fantabulous optics as the original Samyang lenses but now feature an AE chip that talks to the photographic camera.

While information technology's nonetheless a transmission focus lens, the discontinuity is now electronically controlled to allow you to utilize your photographic camera'south P, Tv set, and Av settings instead of resorting to fully transmission.

The photographic camera volition also record the lens information in its EXIF data, then RAW files tin can be corrected with preprogrammed lens profiles.

The new XP 14 mm f/two.four is a nifty lens with good coatings to reduce fringing and ghosting. Like the other Samyang and Rokinon wide-angle lenses, this one incorporates a congenital-in lens hood that makes using screw-on filters impossible.

That'southward not a trouble for astrophotos, but you may need to consider it if you want to use it for other landscapes.

The slightly older version of the lens is still bachelor, the Samyang MF 14mm f/2.8 Mk2. Note that this is slightly slower, just not plenty to exist noticeable. This lens does non have any electric contacts and relies on an old-school twist aperture command band. According to the Samyang website, a Canon EF-M mount version of this lens is available equally well.

Fisheye lenses are uniquely suited for astrophotography.

 They let in a lot of light, and they produce the near expansive field of view possible. What's more than, the barrel distortion that renders them unusable in many situations is much less noticeable in this sort of photo.

 It is nonetheless what I would telephone call a special-apply lens, though, and it'south non correct for anybody.

The Samyang 8mm f/two.8 UMC Fisheye II is a nearly identical lens with very similar specifications.

When in doubtfulness, pick the one that'south cheapest or bachelor at the time.

If you'd like to dip your toes in the fisheye water, there's an even more than budget-friendly option.

The Brightin Star 7.5mm f/2.8 Fisheye sells for merely under $150, making information technology an easy choice for even a rarely used toy.

 As a bonus, it'due south got a diminutive size that feels lite on your photographic camera. This is a relatively new lens, so not much is known nigh it withal.

If you're looking to become into astrophotography, but you aren't quite ready to invest in a special-purpose lens, y'all tin go started with this Canon EF-1000 kit lens.

This lens has a wonderfully broad field of view, and its only shortcoming is its irksome f/iv.0 discontinuity. It's more than sufficient to go started and give astrophotography a try, and having a little bit of zoom capability is overnice when framing different subjects.

Canon makes surprisingly few prime lenses for the EF-Thou mount, only one of the only ones is a decent choice for astrophotography.

It is nowhere near as broad every bit other lenses mentioned on this list; as a affair of fact, the 22mm focal length gives you the equivalent of a standard 35 mm wide-angle lens.

This is an fantabulous lens for travel photography and walking around since information technology is then small. It's likewise surprisingly fast for its size at f/2.0. If you want a lens that can do a trivial scrap of everything, this lens might be for y'all.

If yous're looking for a full round fisheye, the Meike vi.v mm f/two.0 is virtually the only choice.

Round fisheyes are rare finds for APS-C cameras.

 Recall, this produces a circular image with a black frame; it does not make full your sensor. These lenses make a cool upshot, simply they are all-time reserved for special-purpose shots like virtual reality walkarounds.

If you'd like the butt distortion of a fisheye with full-frame coverage, check out the Rokinon 8 mm f/ii.8.

The EOS M Astrophotographer's Guide

What is Astrophotography?

Astrophotography is the intersection between astronomy and photography. It tin be as complicated and scientific as you want it to exist.

Y'all could employ a telescope with motorized mounts and special camera attachments.

Or, you could take the photographic camera you already ain to a dark spot for some nighttime photography nether the stars.

By far, nearly astrophotographers autumn into the latter category. You don't need specialized equipment; information technology's more a subset of landscape photography than what astronomers do with telescopes.

The photos yous capture can exist gorgeous, and it has recently go a trendy genre thanks to the incredible calorie-free-capturing abilities of the new generation of camera sensors.

You lot also don't have to know a lot about astronomy or space to relish astrophotography.

Similar mountains, the ocean, or cities, the stars make a lovely backdrop to well-nigh whatsoever photograph. But some cognition nigh taking these images and a few landmarks in the night sky is helpful.

What are the Types of Astrophotography?

The type of astrophotography you want to do varies significantly with the type of image yous are looking to take.

You can divide apprentice astrophotography into three main groupings based on the field of view you want in your images.

Wide-field images are taken with regular photographic camera bodies and wide-angle lenses.

The wide-angle lens allows plenty light to reach the sensor to enable a photo in very dark atmospheric condition.

The wide-field likewise allows for nightscapes to exist included with some landscape or breathtaking elements like the milky way.

Narrow-field images are taken with a high-end telephoto lens. Several problems with this approach become apparent speedily.

For ane, the more than you zoom in with more focal length, the faster the relative motion of the starfield appears to be.

To capture a blur-free image from a stationary mount, you demand to apply a lot of light and piece of work with a fast shutter speed. The problem with this is that telephoto lenses reduce the bachelor light, requiring deadening shutter speeds.

Images of the moon or the dominicus (if yous accept special filters to protect your photographic camera) can come up out well.

It might be possible to capture images of the planets, such as the moons of Jupiter or the rings of Saturn. But anything dimmer, such every bit galaxies or nebulae, volition be much more difficult.

The third blazon of astronomy photo is taken with a telescope. To capture imagery, a telescope volition need to take a calibrated, motorized equatorial mountain.

These mounts allow the telescope to smoothly rails the stars in the sky, their motion exactly matching the move of the earth's surface. The upshot is that the stars and planets in the viewfinder remain stationary, allowing for long-exposure photography.

When doing this, some photographers mount a telephoto lens piggy-dorsum onto the telescope for wider-field images.

 Others use an adapter to mount their camera to the telescope's eyepiece, in event making the telescope into a telephoto lens.

Special Considerations for Night Sky Photography

If you allow your camera to sit on the tripod and have a long exposure, information technology will become evident that those stationary-looking stars are actually moving.

Of grade, the stars aren't moving—you are.

Every bit the earth spins around its axis, the view of the sky seems to pass by. But as the sun progresses overhead during the day, the stars progress across the sky at nighttime.

The effect is not noticeable with the human eye, but if y'all leave a camera taking a picture show for very long, the stars will show as trails. This is how star trail photos are taken.

 In the northern hemisphere, the stars appear to rotate around the Northward Star (Polaris). When you see star trails that spin around i point like a pinwheel, the photographer has used this outcome to their advantage.

What Makes a Skilful Astrophotography Lens?

If your goal is wide-field nightscape astrophotography, the lens y'all cull should have 2 qualities.

You want a lens that is wide-angle and is as fast as y'all can get.

The goal of nightscape photography is to allow as much lite in as possible. Assuming that you do not have a motorized equatorial mount, the faster the images are taken, the better.

The best astrophotography lenses are prime lenses. Prime number lenses are generally faster than zooms.

The fastest zoom lenses are usually express to f/two.8, and most of those don't get very wide. For the EOS 1000-mount, there are very few wide-bending zoom options.

Focal Lengths

What size lenses piece of work best for nightscapes? In that location'southward room for experimentation and creativity as you frame your images, but the general dominion of thumb is to go as wide as you can.

 A wider lens lets in more light, and it minimizes the star trail event.

Like our eyes, a wide-angle lens barely notices the blur caused past the motion of the earth.

Where a telephoto lens might crave a shutter speed of well less than a second, a wide-bending lens can let yous get by with shutter speeds of ten seconds or more. So the wider your lens, the longer exposure photos you can accept.

Wide angles are also the best from which to capture landscapes and the night sky. These are big epic things, after all.

It only fits that they should need a big field of view to capture them all.

Which lenses piece of work well for star photos? I prefer to use an ultra-broad-bending prime lens. My go-to is one between 12 and 16 mm. It's possible to use annihilation between 8 and 35 mm, or fifty-fifty higher.

But for the reasons mentioned higher up, you lot will have better luck with something wider. The EOS Grand family of cameras have a i.6x crop factor, making a 12 mm lens 19.2 mm in 35 mm equivalents.

To Fisheye or Not to Fisheye?

Broad-angle lenses have some quirks yous should consider. The wider the lens, the more than distortion is nowadays in the concluding image.

The lens tin can be designed to handle the barrel baloney in two means–by creating a fisheye effect or flattening the image out. A rectilinear lens creates a flattened image.

 It's important to realize that even these have distortions, with objects near the edges getting stretched out in crazy ways.

But hither's the adept news–information technology probably won't thing. Distortion in nightscape photography will but be noticeable if a familiar object is placed right on the border of the frame.

 If you utilise a person or a vehicle in your shot, information technology might look bad-mannered. But if information technology's a natural scene, the distortion probably isn't going to depict any attention.

The benefits of shooting with an ultra-wide-angle lens far outweigh the difficulties of dealing with distortion.

Once you option a lens, you lot'll go familiar with its tendencies and frame your shots accordingly.

Circular fisheyes nowadays an entire 180-caste field of view on your photographic camera sensor. These lenses are rare, and for the EF-Thousand, I know of only one–the Meike 6.5mm f/ii.0. When you take the shot, you will get a black frame around a circular image.

This image is not going to utilise your full photographic camera megapixels if you crop it smaller. These are specialty lenses unremarkably used for VR images.

Slightly wider lenses possess the aforementioned barrel baloney, but they fill the frame. These are full-field diagonal fisheyes or full-frame fisheyes.

These lenses are an fantabulous pick for night photography since they let in so much low-cal.

The baloney tin can however be annoying, though, then they're only recommended as a secondary option. In other words, they're fun lenses to play with, but I wouldn't want my only lens to be a fisheye.

There are several fisheyes like this available for the EF-Thousand with focal lengths of eight mm or so.

Rectilinear wide-angle lenses are a little less wide, but they produce a flattened image that is commonly more pleasing to the middle. It's undoubtedly more than useable in more situations.

 The widest ones I know of for the EF-One thousand are 10 mm. There are some zooms available with EF-S mounts that are interesting, too, including the Canon EF-S 10-18 mm f/4.five-5.6 IS STM. Generally, these zooms are also wearisome to be great at astrophotography.

Importance of Fast Lenses at Night

The next important factor to consider in lenses is how broad the discontinuity is, or in other words, how fast information technology is.

A wider discontinuity lets in more light, and that will permit yous to shoot with faster shutter speeds.

In other forms of photography, you might worry about the shallow depth of field produced by an f/2.0 or f/2.eight lens. Surprisingly, this isn't a business organization in night sky photography.

You volition usually focus the lens to infinity, which negates the depth of field result. If you take subjects placed very shut to the photographic camera, you will have to step down the aperture and adjust the focus accordingly.

Manual Vs. Autofocus Lenses for Astrophotography

I've never had much luck getting my diverse camera's auto functions to cooperate in my years of doing astrophotography.

 The focus never works to infinity in dim lite, then that'due south the commencement thing to get set to manual.

To play with exposure settings, I wind upward going to the "M" transmission manner, even with the ISO and sometimes with the white balance.

The upshot is that I seldom intendance to pay for an autofocus lens for this chore. There are a few autofocus lenses bachelor.

If you utilise your super-wide-angle lens for other things like architectural interiors or group shots, I remember autofocus is worth having.

Merely if you're picking up a broad-bending for astrophotography alone, I don't personally see whatever advantage to paying for an electronic lens.

Information technology's perfectly understandable for new photographers to be a little intimidated by working in completely manual terms.

 The thing to remember is that mirrorless systems like the EOS M are virtually as fool-proof every bit you can get. The focus peaking tool allows you to nail any manual focus situation.

The Exposure Triangle for Night Pictures

Something else to keep in mind with this sort of photography is that it is trial-and-fault in nature.

When you prepare up your photographic camera to take a 10-2d exposure, the screen preview might tell you that information technology's going to come out completely black. It doesn't know what it will capture over those 10 seconds, and so you can't preview it.

Then you lot accept your best guess and see what you get.

To make this technique work, you've got to exist the master of the exposure triangle. Yous will need to conform and tinker with all 3 elements—the shutter speed, the aperture, and the ISO setting.

The shutter speed will control how long the camera takes the picture. As discussed above, you lot tin't let this get also long.

If yous leave the shutter open longer than x seconds or so, the stars will start blurring into star trails.

You tin experiment with 15, 20, or 30-2d exposures—I've gotten some decent results with ultra-wide-lenses.

The aperture, which usually controls the depth of field, tin be adapted to the lowest f-stop available.

 If you have objects in the foreground, or you observe that your lens doesn't perform very well at the widest setting, you tin can always step it up from there.

The ISO is of critical importance in night photography. The EOS G cameras typically accept ISO in the neighborhood of 25,600, but you lot might not like the results.

It'south a personal choice, and it depends a lot on the ambient light conditions, only college ISO settings volition produce grainier photographs. Only because information technology does ISO 25,600 doesn't hateful yous should do that.

I try to limit myself to ISO 1,600, or occasionally 3,200, for the best results. Information technology's fun to play with faster ISO images, merely I trash the results more often than not.

Tips for Getting the Best Astrophotos with EF-Chiliad Mount Cameras

Here are a few more tips for getting the most out of your nighttime sky photographs.

• Avoid lite pollution and large cities. Even if the sky appears pretty dark, your camera will pick upward a lot more ambient low-cal than yous realize. Several websites provide maps of lite-polluted areas. They will allow you to plot a form away from lights and find the darkest spots nigh you.
• Permit your eyes adapt. It tin have them up to xxx minutes away from bright lights to become fully adapted to night time. Apply a carmine flashlight if you must, and stay away from vivid lights for at to the lowest degree that long. Your dark vision takes thirty minutes to build up, but it goes away instantly when yous see a bright light.
• Use a sturdy tripod. Nighttime long-exposures can't exist handheld. Yous need a sturdy platform that isn't going to move in the current of air. To farther avoid camera shake, employ a remote release shutter or the Canon Connect app to trigger the photographic camera without touching it. Some remote shutter releases let you to program it to accept any number of photos over a set up period of fourth dimension–a handy feature if you're stacking star photos.
• Discover some apps for stargazing. There are several  hat will teach y'all the constellations and help you lot find the North Star. They'll also give you a heads up about meteor showers or other astronomical events, which might brand interesting subjects.
• It's oftentimes cool at night, then dress for the conditions. Plan to make your stay comfortable, bring chairs and a thermos of something hot and tasty.
• On cool nights, permit your gear get acclimated to the colder weather by leaving information technology outside in your camera handbag. Don't motility information technology from warm temperatures to common cold, and don't have information technology from cold to warm without some cover. You don't want condensation forming on the camera and lens.
• Astrophotography isn't the time to go a minimalist. Have lots of photos, fill up your carte if you must. For every shot yous frame, have multiple exposures with the focus, shutter speed, discontinuity, and ISO all bracketed differently. The final results are frequently much dissimilar on a computer than on the back LCD.
• If yous're afterwards star trails, findan app that will stack the images for you lot. If you have one long exposure, you'll have problems with camera sensor graininess, battery usage, and other elements blurring or getting over-exposed.
• If there are elements in your foreground that are too dark, play with light painting and emphasis lights in your landscape. Lite upwardly the items for just a portion of the exposure time with a flashlight or camera light.
• Practice and effort again. Your results will proceed getting better as you experiment with ISO and aperture settings. Once you find only the right combination for your lens and sensor combination, y'all'll be able to get better results quicker. Ever make it your mission to minimize the corporeality of dissonance in the epitome.

 A broad, fast lens and a tripod are must-have items.

But once you've got that, all you accept to practice is get out and give it a endeavor.
