Fujifilm X-Pro1 vs Sony NEX 7 vs Olympus EM-5 Specification comparison review, all these three camera are the most popular mirrorless camera of today.
First See a quick Specification Comparison
Low-Light performance and Dynamic range
From the specification comparison it is clear that Fujifilm X-Pro1 have big APS-C size sensor and 16 megapixel resolution , the Sony NEX 7 have a high resolution 24.3 megapixel APS-C sensor and Olympus OMD EM-5 have small 4/3 format sensor with 16 megapixel resolution.
From the specification comparison it is clear that Fujifilm X-Pro1 will perform better in low-light condition, bigger the pixel is, the lower the noise : The size of the photodiode and this has a big impact on the dynamic range and low light performance.
Video Performance
Sony NEX7 offers Full HD at 60 and 24 fps, Olympus EM-5 also offer Full HD at 60 fps (but no 24fps) and Fuji X Pro-1 Full HD video recording limited to 24 fps only.
A Image (JPEG) comparison test between Fujifilm X-Pro1 vs Sony NEX 7 vs Olympus EM-5 done at focus-numerique (french website), see the result of test below
 The Fujifilm X-Pro1 JPEG from camera look clear and usable upto ISO 3200, Sony NEX 7 performance is also good but I am really disappointed by Olympus EM-5 High ISO performance.
Conclusion: Fujifilm X-Pro1 and Sony NEX 7 both are excellent performer, buy any one of them.
