ISO Accuracy

The actual sensitivity of each indicated ISO is measured using the same shots as are used to measure ISO noise levels, we simply compare the exposure for each shot to the metered light level (using a calibrated Sekonic L-358), middle gray matched. We estimate the accuracy of these results to be +/- 1/6 EV (the margin of error given in the ISO specifications). Note that these tests are based on the sRGB JPEG output of the cameras, in accordance with ISO 12232:2006, the standard used by camera manufacturers.

By our tests, the E-M5's measured sensitivities are about 1/3 stop lower than indicated across the ISO range (i.e. images are fractionally darker than expected for any given set of exposure values). A discrepancy this small has little practical impact in real world use but means the camera will be slightly flattered in our tests.

Noise and Noise Reduction (JPEG)

Note: this page features our interactive noise comparison widget. By default, we show you the default noise reduction settings of the camera tested, and three other models of the same class. You can select from all available NR options, and from other cameras. The 'tricolor' patches beneath the familiar gray/black/portrait images are taken from the same test chart, and show how noise impacts upon blue, green and red areas of a scene.

ISO range noise comparison

The noise from the E-M5 is very similar to its peers, both visually and numerically - suggesting the 16MP sensor is much closer to contemporary quality standards. The JPEG engine does a good job of keeping noise at bay without sacrificing too much detail (giving it a distinct edge over the Panasonic G3). With, at our preferred settings, with Noise Filter set to off and sharpening turned down, we'd expect a slightly noisier result but with greater detail retention. Either way, it's a good performance at all but the highest ISOs.

Raw noise (ACR 6.7 Beta, noise reduction set to zero)

Again in Raw, the E-M5 is producing very similar results to its peers. To an extent this is because Adobe tries to equalize the output of different cameras but the fact that the Olympus is retaining both detail and contrast at least as well as its competitors suggests the underlying data is at least as clean. The Panasonic's result looks worse but this looks like it is as much to do with the profiling (and lower black-point) than the Olympus, we suspect if we raised the black point to reduce the magenta tinge, the results would be comparable to the E-M5.

It is the only one listed in the camera feature search with a viewfinder as waterproof,but it appears to be only weather resistant, ie don't dunk it in water(or clipped to your life jacket while whitewater kayaking).

OLUMPUS OMDE5 appears to be an interesting camera - I am specially attracted to its weathersealed body and lens ( which I think is very essential in a country like I NDIA) - that was the reason why I had purchased PENTAX K10D years ago. One thing which is bothering me is its made in China tag. I am an architect and basically interested in landscape and nature photography - I travel a lot . Can I am have some inputs from those who are using OLYMPUS OMD E5?

As a hobbyist, I have been using OMD EM5 for more than an year now and I love it. Here are some of my clicks. There are mostly landscapes and outdoors sports shots.

I recently got E-M5 and very happy with it. By no means I'm pro photographer but with my new 12-40mm F2.8 Pro lens is great combat and have been talking great picture. I use Toshiba Flash Air to use with my iPhone/ipad too. I mostly to landscape photos and it has not let me down.

It is an excellent little shooter.
THe EVF is quite good and KILLS OVFs in low light. THese were taken with one ..

The CaNIKSon shooters told me that they got VERY few 'keeper' pics with their FF sensors. I get a few 'looks' while shooting, but they soon shut up when RESULTS are compared.

Anywhere it's really dark, you'll appreciate being able to SEE.

I also own the EM-1 and have yet to put it through its DIM light paces.

I'm on the hunt for a new camera and weighing up my options just now.. I'm fairly new to the game though and a bit naive in all honesty! Is the EM5 much better than the Canon EOS 7D as this comparison...

http://versus.com/en/olympus-om-d-e-m5-vs-canon-eos-7d

suggests? What features make this camera great and what one would you go for?

Thanks, Chad

Hi, I didn't see any answer yet, so I asume nobody saw your post yet. I'll try to help you (maybe you didn't choose yet). This comparison isn't very good in my opinion (for example, it compares 9 fps vs 8, but you have to take in account that is with fixed focus. With continuous focus is much slower and less accurate...). I had a 60 D (same sensor, and image quality as the 7D with different features) and I have now the EM-5. I can tell you it has some advantages (if you think smaller and cheaper very good lenses are important advantages; for me, it is essential), but you will have to sacrifice some speed and easyness of handling. The best way is to read the full review of both cameras and to determine what are YOUR priorities. Don't forget to look at the sample images, as the two cameras have different outputs and it's important if you don't like to spend time in post processing. You will find very nice and helpfull reviews on this site (in my opinion, one of the best). Good luck!

I sold my 7D and lots of expensive L glass after buying the E-M5. The E-M5 is much smaller, it's images are sharper (no anti-aliasing filter), while the 7D has a very strong anti-aliasing filter (much stronger than any of the other Canon cameras with 18MP sensors) and the E-M5 has more dynamic range. It's also not nearly as prone to banding as the 7D is when pulling details from shadows. The 7D is a bit more ergonomic, but it's much larger, and it's lenses are significantly larger. And the reason i sold it is because it's so heavy. The E-M5 is very fast focusing, but for indoor sports (subjects moving towards or away from the camera) the 7D wins. Both cameras are metal bodied and weather sealed. Both have 4 channel, 3 group remote flash triggering. The E-M5 also has tilt screen and touch screen (touch point to focus and take image.)
