|So far, really good. It is a bit of a learning curve though. The menu system is a bit clunky and over-facing, but the camera is really customisable, with 4 buttons, and various other controls that you can set to suite various styles of shooting. Moving from a DSLR, the electronic viewfinder took a bit of getting used to - the first time I tried it made me feel travel sick, but i am pretty much used to it now. The lens is amazing, but quite a big piece of kit (82mm filter size) though. I've had the camera out three times, and each time I find it easier - by mid May I hope it will be second nature. I also got a metabones adapter, so can use my Canon lenses for the time being, although I do plan on keeping my 7D2 for moving wildlife. One huge advantage over the Canon 5D2 and 7D2 is that the RAW files need much less processing - contrast, colour rendition etc are all far closer to what my eye sees, rather than the fairly flat images I've been used to.
I'll give an update in a couple of weeks.
