Sony seems to be on a roll. There are now 3 almost identical bodies out with the FE mount. This was a very smart and cost saving move on Sony's part. The A7 series in my opinion has near perfect ergonomics and producing radically different cameras in the same excellent body helps recoup development cost. The more A7's they make, in any version, the more money Sony saves (and makes). Great job Sony.
I am hoping, fingers crossed, that the next A7 body to be released has the movable sensor array that was reported on toward the end of last year. Much like the old Contax AX, which had a movable film tray for auto focusing with CY lenses, an A7 with this tech would allow for the use of Auto Focus with either old manual focus lenses or with other AF lenses from other makers (i.e. Canon/Nikon) by focusing with the sensor and not the lens.
I shoot legacy glass almost exclusively and while manual focus is fine for most of my work there are times I would prefer a little AF assist. A movable sensor would mean I wouldnt have to carry a whole second set of lenses to make this happen. Then there is also the really neat feature of the AX that allows for macro (or macro like) shooting with any lens without the need for tubes or close up lenses. Examples and explanation of that can be found here. The amazing Contax AX and ‘forbidden’ photography | grumpytykepix
I would like to receive input from the community on two things regarding this subject.
1) Would a movable sensor A7 interest you breathing AF life into legacy glass? Would you consider buying it if Sony released a model like this?
2) And, much more generally, what would you like to see as the next A7? Features, specs, etc.
