Let me first start by saying I'm not a brand loyalist, neither am I trying to stirr up a discussion which is 'better'. I recently sold my 5D3 + L lenses and in the process of either deciding to invest (further) in Sony by buying the A7 (or its successor), or going the Fuji route with the X-system (mainly X-T1 + primes). My main photography is weddings, indoor events and kids/people.
I currently own a Sony a6000 + 16702 + 24Z + SEL50 and I wonder why it is there seems to be so little 'professionals' choosing Sony for their work. Since I've been investigating different systems for a few weeks now, trying to decide what is the 'good' move for me, I bumped into a lot of blogs of professional photographers who either completely sold their SLR setups to go with Fuji, or who use Fuji extensively together with their SLR. I don't see this (almost at all) with Sony. Even though cameras like the a6000 have amazing AF, very good IQ and lens lineup which (if you pay for it) isn't that bad. Same thing for the A7. A lot of photographers seem to like it, but I see very little pro's going the Sony route.
The main reasons I can think of, is mainly the lens lineup of Sony isn't up to par of Fuji (at least quality-wise), but on the other hand, having first hand experience with some of the best glass Sony has to offer, this might be a misconception. Maybe the Sony support is bad compared to Fuji? (which can be a major factor for pro's). Maybe Fuji marketing is doing a better job reaching out to the pro's and Sony is more focussed on the enthusiast?
I really wonder what you guys are thinking about this. I am still very much debating if the Fuji X-T1 + primes can offer me about the same as my 5D3 did, but on the other hand since I already own a Sony system, investing in the Sony FF might be a better bet. Very hard to decide and I must say, by checking out all these blogs, Fuji is pulling me in more and more. It's also strange to see that the Flickr groups seem to show a lot more creativity when it comes to photographs taken with Fuji, compared to the Sony groups which seem kinda generic. Of course it's just the man/woman behind the camera that makes the difference, but browse flickr a bit, the difference is very easy to see.
