Canon EOS-M Review

Looks like you're new here, so welcome! Feel free to look around, check out the galleries, online shop, and the weekly blog. Contact us if you need anything.

Panasonic set the stage almost five years ago by introducing us to the Micro Four-Thirds camera system. I like to refer to it as a Gen 3 camera for its unique feature (or lack-thereof) of not using a mirror in its operation--pretty significant when you think about how long we've had mirrors in our SLR's and now digital-SLR's.

Since that time, we've seen other manufacturers begin to dabble in this technology while being careful not to fully embrace it until it had proven itself. In the age of "smaller is better," combined with the fact that even the most basic of smart phones now take photos that rival the earliest digital-SLR's, the Micro Four-Thirds is getting more attention and being taken more serious.

So now we have the Canon EOS-M camera system. It's been on the market for nearly 8 months now and we've been able to put it through its paces and determine its worthiness as an EOS camera. While consumer opinion has been mixed, you have to admit, it's one pretty cool little camera and with the ability to use EF lens with an adapter, the possibilities are endless. With a retail price of just under $700, it's not exactly cheap but for the right person, it's a dream camera.

Packing a powerful 18 megapixel APS-C "hybrid" sensor and 14-bit DIGIC5 processor, the camera is certainly capable of producing crisp, clean images and is perfectly suited for novice users who are looking for better quality and more options than their current point-and-shoots offer. The EOS-M is essentially a mirrorless version of the EOS 650D but with a much simpler interface and more compact size.

   

The new EF-M lens mount currently supports two lenses natively--the EF-M 18-55mm f/3.5-5.6 IS STM zoom, and the EF-M 22mm f/2 STM prime and with the EF-EOS-M lens mount adapter, all of Canon's EF lenses can be used.

While there is no mechanical viewfinder on the camera, the fixed (non-articulated) 3" touchscreen LCD on the rear of the camera combines framing, focusing, and various exposure options, all in one place. Staying true to Canon quality, the camera features a magnesium-alloy body and although it lacks a built in flash, a hot shoe on the top plate allows it to be fitted with a Speedlite 90EX. The camera is available in black, white, red, and silver.

3rd Generation cameras and the future of DSLR's

A lot of talk has been going on lately about the future of digital SLR cameras and as a professional photography instructor/blogger, I suppose every now and then I'm expected to write about the looming death of some photo technology. Well, today is not that day, but this topic does provide us with the opportunity to discuss exciting advances with digital photography and provide some insight as to the direction we're heading.

The buzz phrase in the digital camera industry right now is "3rd Gen cameras," also known as "four-thirds" or "micro four-thirds" cameras, "EVIL cameras", and a short list of other such names. With advances in technology, some camera manufacturers are starting to push out cameras that produce high quality images utilizing a smaller sensor and no mirror such as the Olympus OM-D E-M5 Micro-Four-Thirds digital camera, seen here. So what does this mean for the future of digital photography? Are these new "3rd gen" cameras ready to take over? Not by a long shot, but let's take a look at how I've come to that conclusion:

There's no denying that at some point in time, all digital cameras will lose the antiquated mirror, a technology that has been in use for for over 60 years since the advent of the Zeiss Ikon VEB Contax S back in 1949. The mirror in DSLR's is a mechanical component of the camera that must flap open and closed with each frame, creating a mechanical bottleneck that directly affects the maximum frames-per-second the camera is capable of. But losing the mirror won't happen overnight, in fact, it will likely be a gradual transition over the next decade.

The camera industry is a multi-billion dollar industry with photographers using billions of dollars worth of digital SLR gear, some of which is very expensive, especially when it comes to lenses. With high quality lenses ranging in price from $500 for a simple prime lens, to more than $14,000 for a top-of-the-line 800mm super telephoto, it's practically impossible from a financial standpoint for photographers to just switch overnight.

Let's take a look at some current issues I see with 3rd Gen cameras that will undoubtedly be resolved over time:

3RD GEN TECHNOLOGY IS STILL IN ITS INFANCY

So should you sell your DSLR and lenses and pick up a new 3rd Gen camera? No, and the reason is simple: These new 3rd Gen cameras are just that, new, and that means the technology is just starting to come to market, accessories are sparse, and there is a lack of lenses for these cameras compared with what is available for DSLR's. The 3rd Gen cameras of today will not be of the same caliber as the ones available in 5 or 10 years. The same was true when digital SLR's hit the market a couple decades ago. It takes a few years to get the ball rolling, test the waters, and see what works and what doesn't.

LENS COMPATIBILITY

It is unlikely 3rd Gen cameras will be compatible with the lenses of today because of the way today's lenses operate. Of course firmware may be developed to allow the camera to capture the old lens' image, flip it like the pentaprism does now, and display it correctly, but most likely, new lens technology will be used to compliment the new cameras. The new 3rd Gen lenses will be smaller, lighter, faster, and quieter than today's lenses which will be a welcomed change for those of us stuck lugging around 15 lbs. worth of lenses through the woods or on a safari.

SMALL SENSOR SIZE = POOR IMAGE QUALITY

Another current drawback that will improve over the next decade is image quality due to sensor size. Right now, the sensor size of choice for most pros is "full-frame," which means the sensor is the same size as a 35mm negative. Both Canon and Nikon's flagship cameras feature a full-frame sensor along with a slightly smaller APS-C sensor used in their sports/wildlife tailored cameras. The 3rd Gen cameras use an even smaller sensor, about 75% smaller than the full-frame sensors. The use of these tiny sensors allows the cameras to be made smaller and more compact, and allows them to be fast by devoting processing power to onboard systems like the digital viewfinder, auto image processing, autofocus, etc. What you end up with is poor image quality at high ISO or in low light conditions--a deal breaker for any professional photographer or advanced amateur.

DSLR's ARE HERE TO STAY... FOR NOW

So for now, digital SLR's are still the way to go if you're looking to achieve pro results from your gear. I anticipate these cameras will continue to be sold for at least another decade or longer and as better and better 3rd Gen cameras start hitting the shelves, they will slowly begin to phase out. The bottom line is, digital SLR technology is HOT right now and each new product launch yields even more impressive specifications. We're just starting to hit the plateau with digital SLR's so you can still feel confident in purchasing a nice DSLR and some lenses without having to worry about obsoleteness for a while.

REVIEW: Canon 24-70mm f/2.8L II

The Canon EF 24-70 f/2.8L lens has been the trusty sidekick for professional photographers and advanced amateurs alike. Because this lens is probably the most common lens you'll find in any serious photographer's camera bag, it's no surprise that many people have been very apprehensive about Canon "messing with" this lens. Well, they've done it, but I think you'll agree after reading this review, it's for the better.

Let's take a look at the new specifications:

Focal Length & Maximum Aperture 24-70mm, 1:2.8
Lens Construction 18 elements in 13 groups
Diagonal Angle of View 84° - 34°
Focus Adjustment Inner-focusing with USM
Closest Focusing Distance 0.38m/1.25 ft.
Zoom System Rotating Type
Filter Size 82mm
Max. Diameter x Length, Weight 3.5 x 4.4 in., 28.4 oz. / 88.5 x 113mm, 805g

 

The notable changes include the addition of 2 elements giving the lens 18 elements in 13 groups, as opposed to the 16 elements in 13 groups of the previous 24-70. Canon also added a zoom lock lever to the lens and as they've been doing with other new lenses, increased the number of aperture blades from 8 to 9, while also increasing the filter size from 77mm to 82mm. The filter size change will certainly irritate some folks but this is the route Canon is beginning to take. If you have used the Canon 16-35 f/2.8L lens, you know that lens also has the 82mm filter size. Having to buy new C-POLS and ND filters for your lenses is often an expensive and irritating process, but at least now you'll be able to use them on more than just the 16-35 lens.

Focusing distances remain the same at 0.38 m/1.25 ft. and the zoom system remains a rotating type. Weight has been reduced from 950 grams to 805 grams, even after adding two new glass elements. The reason for this, of course is the new glass element technologies combined with smaller, more efficient electronics. The new 24-70 also loses 1/2" of length, taking it down to 4.4", but gains about 1/4" of diameter due to the increased filter size.

Now of course, none of this means anything if the lens can't hold it's own against its predecessor, and so for that, let's take a look at the MTF charts:

 

Now, let's compare these with the MTF charts of its predecessor, the 24-70 f/2.8L:

 

Consistent Image Quality Throughout Zoom Range

Notice the thick black line on the MTF charts for the new 24-70 lens. This line represents image quality wide open at f/2.8, and shows the falloff as you move away from the center of the lens. The thick blue line represents image quality with the lens stopped down to f/8. The closer the lines are to each other, the better. From these charts, we can see that the image quality is consistent from center to edge with literally no falloff of quality in the 70mm range, and only 11% falloff in the 24mm range. On the older 24-70, we see some falloff at the edges of the lens in the 70mm range, and a very big falloff at the edges at 24mm, about 80% to be exact. These numbers are very telling and really demonstrate the improvements Canon has made to this lens.

Bokeh

Obviously, we can see there is an improvement with bokeh as well. First, notice how the two thin, dashed lines are so close together on the newer version 24-70. The closer these lines are to each other, and the more consistent their position is to each other, the better the bokeh. The thin, dashed black line represents the lens at wide-open f/2.8, while the thin, dashed blue line represents the lens stepped down to f/8. This lens will be consistent in terms of bokeh from the center to edge. The older 24-70 had a more substantial falloff as it approached the edges with as much as an 85% falloff in the edges at 70mm. Not the case with the updated lens.

Buy, or Wait?

WAIT. The original 24-70 f/2.8L is such a good lens, has been my "walk-around lens" for years, and like many other photographers, it's difficult to accept that there could ever be a worthwhile upgrade for such a great lens. But, after looking at the performance tests of the new 24-70 lens, it's easy to see how this really is a worthwhile upgrade, especially with the lens being so popular amongst serious photographers. However, with an MSRP of $2,299, nearly $1,000 more than what its predecessor sold for, and the same price you'd pay for the 70-200mm f/2.8L IS II, the lens is overpriced by $500 to $700. That said, I do NOT recommend an upgrade at this time. Keep your original 24-70's until the pricing becomes more reasonable.

REVIEW: Canon 1.4x Series III Extenders (Teleconverters)

The new Series III extenders (teleconverters) from Canon are pretty amazing for when you need that extra reach, but don't want to reach too far into your pocket to pay for it. But how do the really stack up (no pun intended) against each other, and is there really a noticeable loss in image quality like so many doomsday critics say? We used a Canon 7D camera with a Canon 70-200mm f/2.8L IS II lens for this test and these were our observations:

Construction & Durability Improvements

The extender is solidly built and there was no movement or play when affixed between the camera and lens. These new Series III extenders have 7 screws holding the mount plate together where it attaches to the camera body; an upgrade from the 4 screws used on the previous generation of extenders. For some reason, Canon only added the extra screws to the side that mounts to the camera body, not the side that mounts to the lens. We're not sure why but it does seem like reinforcing both sides of the extender would have been nice. The extenders are weather sealed so it shouldn't be a weak spot if you're shooting on a 1-series camera with full weather sealing.

Image Quality

The image quality was very good in our tests throughout the aperture range, something the 2.0x Series III extender was not able to achieve. The 2.0x did a decent job at maintaining sharp image quality but the 1.4x did an awesome job and you can see that in the side-by-images below. There is not the noticeable degradation in the lower aperture range (f/5.6 and f/6.3) as we saw in the 2.0x extender. Even though the 1.4x extender only causes you to lose one f-stop instead of the two stop loss you get with the 2.0x extender, we decided to test both extenders starting at the f/5.6 setting for consistency.

Conclusion

So is this extender usable? Absolutely. Whether or not you buy this extender will depend a lot on how much image quality you're willing to lose and how much money you're willing to spend. At $475, the 1.4x Series III extender is a very affordable alternative to buying an expensive 400mm lens that could easily cost 20 times as much money and with the relatively negligible amount of degradation, it's definitely worth considering.

TEST CAMERA: Canon 7D
TEST LENS: Canon 70-200mm f/2.8L IS II USM
*** Please keep in mind, this was a very basic test, using only one lens, one camera body, and one lens focal length (doubled with the extender to 400mm). The results will vary based on your particular camera/lens combination but this should at least give you a basic idea of how much image degradation you can expect to lose with the extender.

REVIEW: Canon 2x Series III Extenders (Teleconverters)

The new Series III extenders (teleconverters) from Canon are pretty amazing for when you need that extra reach, but don't want to reach too far into your pocket to pay for it. But how do the really stack up (no pun intended) against each other, and is there really a noticeable loss in image quality like so many doomsday critics say? We used a Canon 5D Mark II camera with a Canon 70-200mm f/2.8L IS II lens for this test and these were our observations:

Construction & Durability Improvements

The extender is solidly built and there was no movement or play when affixed between the camera and lens. These new Series III extenders have 7 screws holding the mount plate together where it attaches to the camera body; an upgrade from the 4 screws used on the previous generation of extenders. For some reason, Canon only added the extra screws to the side that mounts to the camera body, not the side that mounts to the lens. We're not sure why but it does seem like reinforcing both sides of the extender would have been nice. The extenders are weather sealed so it shouldn't be a weak spot if you're shooting on a 1-series camera with full weather sealing.

Image Quality

The image quality was pretty decent in our tests, especially at the higher aperture settings. There is a noticeable degradation of image quality at the lower aperture settings, specifically at f/5.6 and f/6.3. The image quality past f/6.3 was pretty consistent with only minor degradation at f/8 and almost no difference at f/11. The one problem we do see with this, however, is that most people using this extender are using it for wildlife photography and birding. For that type of photography, you need a wide aperture to let in enough light to maintain the high shutter speeds. Since you will lose two f-stops when you use a 2x extender (one f-stop for the 1.4x extender), your widest aperture on an f/2.8 lens will be f/5.6 which is where the highest amount of image degradation appears.

Conclusion

So is this extender usable? We think so. Whether or not you buy this extender will depend a lot on how much image quality you're willing to lose and how much money you're willing to spend. At $475, the 2.0x Series III extender is a very affordable alternative to buying an expensive 400mm lens that could easily cost 20 times as much money.
