Sony is keen to portray itself as a genuine contender in the imaging market. Currently, it is doing this through innovation and experimentation, of which the A7R is a prime example.
What we have here is the world's smallest and lightest full-frame interchangeable lens camera - an extremely exciting development, especially for the compact system camera market. It's fair to say that traditional DSLR manufacturers may be starting to get worried, especially given the price points at which the A7 and A7R are available.
Image quality is top class, especially in terms of detail. Colours are beautifully vibrant, while the scope to customise colour output in camera is very much appreciated.
It's clear that Sony has thought about how enthusiast and professional photographers like to work and the amount of button customisation available is wonderful. It's great being able to make the camera work exactly as you want to, or the way you think is most sensible.
While the camera is small, it's still chunky enough to sit nicely in your hand, with a grip on the side making it comfortable to hold for long periods of time – always a bonus.
It's great to have a tilting screen too, something which currently only Sony offers for full-frame cameras. It helps when shooting at awkward angles, or if there's a lot of glare. The EVF is also excellent. Although it can't compete particularly well with an optical finder in some dark or high contrast situations, the rest of the time it's better in many ways – being able to quickly assess whether you've nailed a shot is particularly useful.
That's not to say that this camera isn't without its flaws. The battery life is poor, and if you're looking to spend a day with this camera, it simply won't last that long. I'd recommend investing in two additional batteries if you want to use it all day – thankfully the batteries are small and pocketable.
It also remains baffling that Sony doesn't include a touchscreen on a camera like this. While the enthusiast/pro photographer might not be bothered by such technology, the fact that Sony has access to this in spades makes it more of a glaring omission, especially when you consider how fiddly it is to change the autofocus point.
Image quality from the A7R is, quite simply, superb. That's by far and away the best thing about this camera, and we're excited to see how the system develops from here on. With the addition of more lenses and more accessories, it should become an attractive system to get on board with.
It has to be the battery power - you will be forced to buy another battery. It would be nice if Sony could include a spare in the box, especially as you're already shelling out a significant chunk of change for a camera like this.
Both the Sony A7 and the A7R are fantastic innovations. But for now, the system isn't quite complete enough. Although image quality is fantastic, it feels as if there are a few kinks that need to be ironed out, most importantly improved battery life, and hopefully the introduction of a touchscreen for the next iteration of the camera. With only one proprietary lens available for the R model at the moment, it's a little limiting. But compatibility with other lenses via optional mounts makes it extremely intriguing for users considering moving to Sony from other brands.
