Overview


As promised, I have performed some additional dynamic range tests on the mirrorless cameras I am testing (Nikon 1 J2, Canon EOS-M, Sony NEX-F3, Sony NEX-5R, Sony NEX-6, Sony NEX-7 and Olympus OM-D EM-5) and I have the data ready for your viewing pleasure. As expected, the Sony APS-C sensors performed the best, with the Sony NEX-5R and NEX-6 leading the game (although other NEX series are extremely close) followed by the Olympus OM-D EM-5, then Canon EOS M and then finally the Nikon 1 J2. Here is a comparison chart that shows performance of the various mirrorless cameras:
I have spent a considerable amount of time working with 7 different mirrorless cameras from Sony, Canon, Nikon and Olympus. I apologize for not being able to provide periodic updates on these cameras. I have come up with new ways to measure digital camera sensor performance, so it took me a long time to do it in a way that I believe will be more accurate and objective compared to my previous methods. Not only will you be seeing crops of sensor performance in a controlled environment, but I will also provide some numbers to quantify performance in colors and dynamic range. As I have already mentioned before, I will be measuring dynamic range myself going forward without having to rely on other websites for the data. It will be interesting to see how my data compares to other sites like DxOMark. I am not planning to do anything super intensive and I bet my measurements will not be without issues and errors, but I believe it is something worth trying. Hopefully it will give a different perspective to testing sensors.
Here is the first test that shows the low light performance of the following mirrorless cameras: Nikon 1 J2, Canon EOS-M, Sony NEX-F3, Sony NEX-5R/NEX-6, Sony NEX-7 and Olympus OM-D EM-5. Since these cameras all look excellent at ISO levels between 100 and 800, I decided to only show ISO performance at 1600 and above. Take a look!
I recently had the opportunity to spend some time with the GX1. Although I have owned some compact cameras and occasionally have the chance to experiment with those of others, this is the first mirrorless camera I have used. As Nasim and others have indicated, mirrorless cameras will increasingly play a larger role in the digital camera market, due primarily to their smaller size, lighter weight, reduced mechanical complexity, and faster FPS ( frames per second speed). They provide an impressive range of features in extremely small packages. But mirrorless cameras such as the GX1 still represent a modest investment and thus do not offer any cost reduction relative to entry and midlevel DSLRs. In this Panasonic GX1 Review, I will provide detailed information about the camera, as well as image comparisons to other DSLR cameras.
Some of my questions prior to receiving my GX1 included:
