Review: Olympus OM-D E-M5 (Compared with Sony NEX-7, Fujifilm XPro1 and Canon Rebel T4i/650D)


Olympus OM-D E-M5 (IN STOCK at B&H)

When I reviewed the Sony NEX-7, my opinion of mirrorless cameras really started to change. It’s a game changer camera that offers a reason to go small and pass on a DSLR, so when I heard all of the hoopla about the Olympus OM-D E-M5 being even better than the NEX-7, I knew I had to check it out.

First Impressions

When I unboxed the Olympus OM-D E-M5, I was immediately reminded of the quality of the Fujifilm X100 and X-Pro1 bodies which is a good thing. However, when I turned it on I was even more pleasantly surprised that the rear OLED display blew away that of the Sony NEX-7 and pretty much everything else I’ve used. The rear display offers a tilt feature, but it isn’t quite as useful as the fold and rotate design found on Canon cameras like the T4i and the G1X. It also offers a touch screen which I usually have disabled, but it’s fantastic for photo playback where you can swipe to see more photos, zoom (via a slider only), and pan very easily. This big 3.0” display is the future of camera rear display technology that other brands will hopefully adopt in the future.

This camera also offers an electronic viewfinder which is a big let down as the display quality is horrible compared to the rear display and not even close to the quality and brilliant design of that found on the Fujifilm X100 and X-Pro1 bodies. In short, it works (and is handy in bright light) but it’s more of a checkbox feature than a purchase consideration feature like the Fujifilm cameras.

Olympus M.Zuiko Digital ED 14-42mm f/3.5-5.6 II R Lens

I had the Olympus M.Zuiko Digital ED 14-42mm f/3.5-5.6 II R Kit Lens and the Olympus M. Zuiko Digital ED 45mm f/1.8 Lens with my review unit, but I quickly hated the 1.64’ (0.5 m) minimum focus distance of the 45mm f/1.8 prime so I favored the 9.8” (24.89 cm) minimum focus distance 14-42mm for most of my review period.

In my testing I found the battery to last longer than some of the other models I’ve used, but it is still only good for about one 8GB SD card under normal use. Speaking of the battery, this camera has a separate door for changing SD cards that isn’t coupled with the battery so that allows for real-time swapping without turning the camera off which is nice.

I found the grip to be excellent and the controls to be fairly nice, so ergonomically I’d say it’s a great design. However, the in-camera menu system – while visually appealing – were cumbersome to use and I found myself lacking quick access to hard buttons for some of the features I wanted handy (although the two programmable function buttons can help). The toggle for the viewfinder to rear LCD wasn’t super obvious, and the purpose of the function buttons felt illogical but other than that most buttons were easy to figure out. The rotating knobs were great and didn’t accidentally get bumped, and the power switch was fantastic. It should also be noted that with a rear touch screen, it’s possible to to address some of my concerns without reprogramming anything but I still found the touch screen to easy to bump to leave it activated at all times.

As of the time of this article, I haven’t done any flash photography with this camera yet using the Olympus FL-LM2 Flash that is included with this body (even body only units).

Video


Play in HD

People who follow my blog know that I hate doing video, so I put zero effort into my videos. This is just another one of my typical “follow my son on his trike” videos where I test the auto focus and zoom during a lame real-time HD video. This is Program Mode video with default settings, but there’s lots of control over what you can do with video so my impressions are that it’s above average for cameras in this class.

Noise Concern

At first when I started using this camera I was blown away as it’s rear OLED display is very good so the images I took looked fantastic. However, the in-camera JPEG’s are very heavily processed (I’d say much more than other brands) so it seems to be noise free even into the higher ISO’s. My first gut impression was “wow, this is better than the NEX-7 and even the Fujifilm X-Pro1”. As I dug deeper I discovered that this was an illusion as the noise found even at ISO’s as low as 1600 was what I’d classify as excessive as you can see here:

Olympus OM-D E-M5 Noise at ISO 1600 
100% Crop of RAW file at ISO 1600

The in-camera noise reduction is horrible too as it destroys detail as you can see in the couple 100% crops below from an ISO 1250 image:

Notice how hair detail is lost

and the details in the shirt are obliterated

As a result, if I were advising a friend who owned this camera I’d say turn off ALL noise reduction and use Noiseware or Dfine instead as they do a much better job of preserving detail and not introducing artifacts.

DPReview’s comparison images seemed to indicate better results than the NEX-7, but that is not what I experienced in real-world usage. To my eyes the NEX-7 and X-Pro1 had a significant advantages in real-world noise handling and performance.

It should be noted that my camera came with version 1.2 of the firmware for the body and 1.1 for the zoom lens.

Autofocus Performance


f/5.6 @ 42 mm, 1/1000, ISO 2000
(Compare this to a T4i image at the same location here)

The bottom line with this camera is that it’s non-tracking focus (aka one/single shot) is outstanding, but it’s focus tracking (i.e., continuous/servo focus) is horrible. This is an improvement over a camera like the Fujifilm X-Pro1 which struggles to focus lock on static subjects indoors as focus locks happen quickly, but it just can’t track which is a shame given the fact that it can do about 28 JPEG fine or 20 RAW 4:3 full resolution images before any slowdown occurs and it never fully stops in either mode. This camera has all the makings of a great compact sports camera, but the reality is that its noise performance and terrible continuous tracking prevents it from being suitable for this purpose (see my 5D Mark III review for what’s possible these days – or T4i for the budget conscience).

The single AF mode is the way to go, but even at 1/1000 sec predictive focus is necessary for a moving subject as you can see here:

image
f/5.4 @ 38 mm, 1/1000, ISO 800

In this shot my son is swinging, but very slowly so 1/250 sec should be sufficient to stop his movement but I was aggressive and went for 1/1000 sec. During my swing tests I only managed to get about 6 out of hundreds of shots that were usable which is pretty rare these days. Even my X10 point and shoot can outperform this camera at continuous focus tracking.

Exposure Metering

I think a firmware update is order for the in-camera ESP metering as it would randomly get seemingly easy shots over or under exposed. However, the good news is that it’d usually only get one frame wrong and then be back on track. I worried that I might have been accidentally hitting the AEL button which gets programmed to Fn1, but I disabled it to prevent that from happening and I still saw this problem.


ESP and Spot metering gave identical results for this shot

This might be a reasonable ESP exposure, but the funny thing was that shooting in spot or center-weighted metering, I got the same results. I’d expect spot metering to brighten my subject at the expense of the background as other cameras will do, but not the E-M5.

It should be noticed that when I did my metering testing I was in Aperture Priority mode.

Sound of Camera

The first thing I noticed when I turned this camera on was that I could hear it make a low gurgling sound that reminded me of an old air conditioner. I got used to it, but it’s the only modern day camera that I can recall being audible to the point of noticing when turned on. Turning of image stabilization, going to manual focus, etc… didn’t help – it’s just a noisy camera. It didn’t seem to impact the video in a significant way, so I wouldn’t call it a huge problem. It’s just something to keep in mind if you are going to turn this camera on in a quiet place as people will hear and notice it.

Compared with Sony NEX-7, Fujifilm XPro1 and Canon Rebel T4i/650D

Personally, I think the T4i/650D outperformed this camera in all but the quality of the rear LCD and size. The Sony NEX-7 would still be my recommendation for those looking for a mirrorless camera, and the X-Pro1 still wins the dynamic range comparison by a huge margin.

For those who are price conscience, I’d say go for the T4i/650D. For those who are size conscience, I’d suggest the Sony NEX-7.

Conclusion

This is a nice camera that I started to love right away. Based on the gorgeous rear LCD image previews, I expected this camera to dethrone the NEX-7 as the best mirrorless camera – but it didn't. In fact, this camera really reminds me more of the X-Pro1 where it has tons of potential but is missing some key things that hold it back (noise, metering performance, and AF tracking). However, I think the Olympus faithful will still love it. It’s a good camera that just a couple years ago would have blown the competition away, but competition is stiff so I just can’t help but thinking that Olympus has some bugs to resolve before this camera can start attracting Sony NEX customers.

This camera has a great sensor for capturing detail and the kit lens takes advantage of it. This made it a fun combo for macro shooting.

The Olympus M. Zuiko Digital ED 45mm f/1.8 Lens did great on SLRGear.com’s blur index testing, but I didn’t care for it as much in real world usage. I much preferred the 14-42mm which did okay on SLRGear, but seems less sharp – but in practice I found it to be a great overall lens.

I usually shoot jpeg with my other cameras, but I shoot RAW with the OM-D because results are substantially better (detail, noise, color etc.). Also, lenses make a big difference on the OM-D. For chasing my 3 year old grandaughter, nothing beats the Canon 5D3, but I can also get very good results with the Olympus. I agree with your evaluation points except that the electronic viewfinder works well for me. Thanks for the review.

Ron Martinsen said...

Just to be clear - my gripe with the elecronic viewfinder isn't its usefulness - it's primarily the quality of LCD used. It is much lesser quality than the OLED rear display (as you would expect for price reasons) and the color accuracy and resolution are both lacking. Fujifilm has done a much better job with the quality of the LCD used for their viewfinder so I wish Olympus would have simply used a higher quality display and matched its color calibration to the rear display.

It's usable, but its not a high quality LCD in the electronic viewfinder.

Willi Kampmann said...

I switched from a NEX-3 to the OM-D and noice performance is slightly better because the OMD doesn't tend to produce blocky artifacts as much as the NEX-3 at higher ISOs (3200 and up). The NEX-7 to my knowledge has slightly inferior noise performance to the NEX-3 because of its higher pixel count. I really can't confirm your results.

Same goes for the EVF: It's getting praises everywhere, and rightfully so: It's fast, sharp and bright. The NEX-7's EVF is supposed to be good, too, but I've heard it's too constrasty and you can't configure it manually.

You've also ignored one of the biggest advantages to the OMD (and the reason for the "air conditioner"): The terrific IBIS. Its stabilizing capability is among the best of the best and it works with any lens.

I had the choice between the NEX-7 and the OMD, and I'd choose the latter every time again. Both cameras are terrific, but yours seems to be broken. Seriously.

I am surprised you were shooting up to f11 for your review. The limit of aperture diffraction on this sensor is just above f5.6

Valerij Tomarenko said...

I am a little bit surprised at three (!) instances of the word "horrible" in a relatively short review. I certainly disagree as regards the EVF (i.e. it being "horrible"). As far as I know it is also the same EVF which is used for Leica X-2. I have both OM-D and Fuji X100 and cannot tell that the latter (Fuji) has some advantages over the EVF of the OM-D, but I can be mistaken. Thanks for the review!

Ron Martinsen said...

Willi & Vallerij,

Perhaps some additional context will help. As part of my job I have the opportunity to work with high quality displays from NEC and Eizo, and I work closely with X-Rite doing color accuracy related reviews. This work and mynprinting expertise has trained my eye to be very sensitive to color accuracy and image detail. As a result the first thing I noticed about this EVF was that it wasn't color matched to the rear LCD. This coupled with the fact that the rear OLED has such outstanding pixel density versus the EVF which has the pixel density of a cheap TV LCD is the basis of my complaint.

Ron Martinsen said...

Matt,

Go to take a look at the blur index of the 14-42 on SLRGear.com (http://slrgear.com/reviews/zproducts/olympus14-42f35-56m2/tloader.htm) - f/11 is well within the sharp range of this lens.

Don't worry so much about diffraction theory - look at the images and what the camera actually does at the various apertures on the blur index. Yes, it's true that f/5.6 is its sharpest (much like f/8 on a full frame), but diffraction doesn't become problematic until f/16 with the 14-42mm lens.

Ron, I enjoyed your review. The OM-D is a very good camera and I think you agree with that in your review. I do think that the rear OLED screen is superior to the EVF but what I do like about the EVF is the refresh rate - I don't see the color tearing that I see in my Panasonic. The sensor is quantum leaps ahead of the old Panasonic sensors but, I do think that the OM-D's sensor lags a bit behind the best APC-S sensors in clean high ISO's but coming from a GF1, it's still refreshing to shoot at 1600 ISO. Anyway, I've enjoyed going through your site and I like your real world review style.

Bill, Teri, Mira + Mei said...

Hi Ron,

I wanted to follow up about your reviews. I really like that you use the cameras in everyday situations and then report on what weeknesses you find. I think this is important for people that are less knowledgeable about cameras and are looking for real world advice on how a camera operates. I own an OM-D and I would not disagree with much of you wrote about it - it is a fine camera but, it has it's warts and any camera model or brand does. There is not perfect camera (system) out there and it's good for all of us hear that once in a while - no matter what brand we use.

Ron Martinsen said...

Bill,

Thanks for your posts! I'm glad you see the value in what I'm trying to do. I post real-world feedback rather than gloried press releases because I take the time to put myself in the shoes of someone who has invested their hard earned money in these products.

I don't put negative feedback to hurt peoples feelings or make them feel bad about their purchase. I just want to help people understand some real limitations they'll discover if they go with this product so they aren't surprised. I'm also optimistic that this feedback will be seen by the camera makers with the hope that they'll address these concerns.

No product is flawless, and to some extent - thanks goodness! If it they were really perfect we'd all be running around with the same exact camera and I wouldn't be able to enjoy evaluating cameras anymore. ;-)
