I'm a Sony shooter who is currently looking to move to Canikon mainly because of the poor selection of longer reach lens options available to the Sony A mount system.pig hunter wrote:The Sony may have won the CoTY award

The A7RII is undoubtedly an astounding camera but it is not, and never will be, an action camera, that development may come at some stage, but not now. It is a superb tool with the best sensor so far made in terms of image quality, dynamic range etc. The others WILL catch up. It is the camera functions which let it down. Stupid things like a small battery giving poor life, poor interface and small fiddly body. Don't get me wrong here, if I was after a camera for travel/landscape/scenery/architecture etc then the Sony would be very high on my list, probably at the top.
Remember that the 5DS is not marketed as an action camera either although it can be used with a reasonable degree of success. At least it has a decent sized body with well established interface. I expect if would be popular for wildlife with long lenses allowing a good hard crop but still giving a large useable image.
For now I certainly wouldn't buy either of them, they just don't excel at the subject matter I shoot (or try to!). There are better cameras for action/aviation.
With regard to finding long lenses for the Sony A7RII, you can get loads of long primes for it, in fact any Canon or Nikon prime will fit it as will the Sony 500mm f4. With the latest adaptors, they will all autofocus too. Any lenses without IS or VR will benefit from the Sony 5-axis built in stabilisation system.
