Toothwalker, why not? Any specific reason? Being able to use my EF mount lenses with Sony sensor looks appealling.
Using an EF mount lens on an A7 is one thing, abandoning Canon altogether is something else. I asked myself the same question. The answer, for the time being, is no. The main reason being that it won't improve my photography.
It will reduce the stress on my shoulders, but to achieve that I need to replace a few lenses as well. On serious photo trips I carry a DSLR and five lenses from 21 to 200 mm, YC mount and EF mount. My shooting style is shoulder bag, quickly grabbing and changing lenses when needed. With an A7 I might get one or two native lenses, but for the remaining lenses I don't want the hassle and delay of relocating adapters from one lens to the next. If I equip all lenses with a separate adapter, which is also a costly business, the total weight may even be larger than before.
Advantages of the A7/R are (for me at least):
1) Weight reduction.
2) State-of-the-art sensor in a small package.
3) Reduced vignetting with large-aperture lenses.
Disadvantages and uncertainties are:
4) Weak/absent AA filter (some people don't mind aliasing, but I do).
5) Vibration blur at certain shutter speeds.
6) Edge smear and color cast with quasisymmetrical wideangle lenses.
7) Bad flares with shiny adapters.
8) Reports of excessive noise at low ISO.
9) Persistent rumors of Sony applying irreversible processing to the RAW files.
10) One is forced to use crappy Sony software to get the most out of the RAW files.
11) It is unclear whether the performance of the native lenses depends on compensation, in the lens design, for the astigmatism of the sensor filter stack.
I am sure the A7 has a better sensor than today's Canon DSLRs, but I have a hard time finding confirmation from the images shown in this forum. When there is a clear difference in image quality, it is mostly because of 6) and 7). Some of the negative points and uncertainties will go away as solutions are found, or may prove to be incorrect, but I am not going to ditch my SLR just like that.
I may consider the A7 as a second camera though, probably best used with native lenses to keep the package light and hassle-free.
