just read this on steve huff's 17mm review for micro 4/3
Sorry if this will make you doubt, nianys
Fuji X has a couple of good lenses and their 35 1.4 can be spectacular, in good light and when it focuses correctly. I took the X-E1 with the 35 1.4 to the same event and again the Fuji left me frustrated and I missed so many shots due to the AF missing the focus point. When the Fuji is indoor in lower light or funky light the results are not usually very pleasing as the AF is slow and the AWB is not up there with the best. It throws out funky color casts if you are in some indoor low lighting. I am hoping and have faith that the X100s delivers on speed and accuracy (and I think it will) and improved AWB. I feel the X bodies are more like beta models being tested by those who buy them. No offense to whoever owns them and loves them, and MANY of you do, it is just not working for me as they are much to quirky and for my tastes, there are better options out there right now in my opinion.
I can say the X-E1 and 35 1.4 taken out in good light or sunlight or studio light will reward you with a super nice image that draws you in to it with nice depth and colors. But side by side indoors low light other cameras do much better. I know, I shot them all.
So for me, I would take the E-M5 and 17 1.8 or 25 1.4 over the X-E1 and 35 1.4. I just do not get along with the Fuji X bodies. The images I get from the E-M5 are more to my liking, and the best part is, I do not miss shots due to slow or dodgy AF. I would also choose it over a NEX right now just due to the masterpiece lenses available for the Micro 4/3 system. The 12mm, the 45 1.8, the 75 1.8 and the 25 1.4 from Panasonic.
Again, I just write what I feel from MY experience and I am always 100% honest about my experiences. The OM-D E-M5 can give you back very rich and glassy images
