Should I place pre-order for 5DSr or wait?

However, it could be time to wait a little before purchasing one new, because the A7RII should be announced soon, says Sony Alpha Rumors. If Sony has implemented a few improvements from the current model as well as a 50Mp sensor in it, it should be an awesome resolution tool.

Don't count on it. The A7RII is rumoured to have the same 36MP sensor with the main feature being in body image stabilisation. For landscapes this feature is mostly redundant. Of course just because the resolution is the same doesn't mean that there won't be significant improvement in image quality.

Right. But in order to have in body image stabilisation, a slightly larger CMOS is required, am I wrong? Maybe the early 50Mp rumor was correct, but the remaining resolution after the stabilisation cropping is only 36Mp?

…Which leads to another question: will the A7RII have a crop factor, or is it engineered so that it will remain a full frame?

…Which draws another thought: would it be technically possible to implement a taller 3/4 ratio 50Mp sensor in a mirrorless camera, either from Canon or Sony? Putting a taller shutter in such a tiny body is probably a technical challenge, but this could become a real alternative to a medium format system. Many existing lenses would probably cover the slightly larger IC. Just thinking loud…

I guess that the shutter vib issue is something linked to lightweight tele lenses, for I am not seeing it with L-lenses attached to it, nor with the Mamiya 645 lenses. And secured on tripod with a L shape quick release bracket, you get the sharpest shots. The L-bracket adds a little weight to the body and probably helps dampen the shutter vibration when the camera is hand held.[/quote]



Are you using a lens adaptor ?. I've heard of light leekage issues with the Metabones

Canon made the first DSLR with 50mp just to be the first to break the 50mp barrier.

Maybe, they still have to release the camera. Sony may beat them to releasing, why else would Canon announce so early?

I purchased the camera second hand, and there was an adapter in the package. It is branded "King". It is solid all metal and so far: no problem. You could probably buy 3 or 4 of them for the price of the Metabone, and I am not sure that the later would offer something more. Can't make a direct comparison though.

I use the Mirex EF T&S adapter on a plain dumb adapter to Sony. Works well, no vignetting at all. The "King" does not vignette either with the shift adapter, but it has electronics. It is better not to short the contacts I've heard.

I'm gonna buy a 5Dsr, but...am going to wait to get my hands on a refurbished one.
Will have been checked out entirely before being resold.

and don't forget 11-24 on the way out

Can't justify the 11-24 at the moment. My 16-35 f4 has been good enough at this stage. I'm thinking my next lens will most likely be in the 200-400mm range. Most likely the new 100-400. Canon do have a great lens selection.

IQ on new 100-400 is very close to 70-200 f2.8 IS II. AF is fast with my 1dx. I shot from 100mm to 400mm, I don't see any issues with IQ from wide to tele end.

16-35 f4 IS is EXCELLENT for the money, however, I'm itching for that 11-24
