First of all what did I like? Well for a full frame camera, high definition system, it's a small camera body with nice controls, beautiful RAW files and overall impressive image quality. My first couple of weeks with the system had me excited about some of the photographs that I was producing, the amazing detail and resolution in my work, but this quickly wore off as I realised that this system was changing the way I work, and not in a good way.
I started becoming one of the DXO enthusiasts, the pixel peepers, blowing up every individual photograph for hours at a time and admiring the clarity and resolution in my files instead of going out and making photographs. I was becoming everything that I hate about photographers. Let me just say there's nothing wrong with wanting your photographs to be perfect, I want that. What I was doing though was telling other photographers online and in person about how sharp my photographs were etc. In a strange kind of way this seems to be a common theme amongst the Sony A7 series photographers. The online groups dedicated to these cameras on social media and photo sharing websites seem to be flooded with these type of users. Way more than I've ever seen on any of the Fuji equivalent sites.
There were a few things with the camera that I really disliked as time went on. Terribly slow autofocus (almost impossible as the light fades) and a shutter that was so loud that I thought I was launching grenades from the end of the lens barrel. These are fairly well documented so I won't say any more on them. You can read about those elsewhere. A quick side note about the shutter, a number of users complained about shutter shock on their A7 series bodies. I never noticed it during my time with the A7R.
There were also a few niggly things in the menus that I didn't like though, for example having to navigate to an option to enable the camera to use a cable shutter release. My Fuji's just allow me to do it automatically when you plug the cable in. The menu and settings don't feel very intuitive and it can be quite tricky and time consuming to locate a specific function or setting which is no good if you're working under time pressures.
One thing that bothered me the most was the lack of support or interest from Sony in terms of listening to their customers. Let me compare with Fuji again for a moment. Any flaws in a camera or new feature requests to Fuji are corrected and added regularly through firmware updates. For example, the X-Pro1 camera is now over 2 years old but has just recently been updated with new features (The ability to finely tune your autofocus with the manual focus ring), making it feel like a new camera again. Sony doesn't appear to be listening, or really attempting to fix things and add new updates in a way that Fuji does. The Sony user base are screaming at a brick wall as far as I can tell. The firmware updates do come with Sony however they are incredibly difficult and temperamental to install and never really seem to address the issues fully (see any Sony forum for scores of complaints). The process involves downloading an installer on your computer and connecting the camera via a usb cable. The process is laborious and finicky and many Mac users have been unable to run the installer or ended up bricking their camera. I had the pleasure of updating the firmware twice via someone else's windows machine and the only slight improvement in the camera was a slightly faster boot up time, that's all. Fuji in contrast make it very easy to update via a file that you simply upload onto an SD card and install directly onto the camera body.
Other things that I didn't like included the Sony FE lens collection being very limited too. There's only a limited selection of lenses, admittedly for a fairly new system. There are now however almost as many camera bodies available as lenses. Sony needs to focus on getting more lenses out there instead of a new body every 5 minutes. The few lenses they have are very well built but are a bit on the large and heavy side for a compact system. One of the arguments that I've heard against the limited lens selection is that you can get adapters which allow you to use lenses from Canon, Nikon and also legacy glass via the M-mount adaptors. But really you're adding to the bulk again, thus defeating one of the major benefits of the smaller mirrorless systems, not to mention it looks really weird and bulky. In some cases the autofocus doesn't work with these lenses either leaving you to focus manually. Fuji by comparison have an ever growing lens selection and they listen to what lenses their users want too. This is how to please your customers! Fuji do have a head start on Sony in this sphere so it's only fair to cut them a little slack.
