It puzzles me why people use as the basis for size comparison of interchangeable lens systems a single lens mounted on a camera. Once you start to carry multiple lenses, the shorter register system will almost always lose, because the extra length has to be on every lens instead of once on the camera turret. We have seen that most lenses don\'t take advantage of the short register distances e.g. because of ray angle in wides.
I guess there is a specific preferences at work here. FMers overwhelmingly use lenses in the 28-85 range, especially 35-58, and focus more on specific rendering characteristics. There are some SWA users as well, and they will have trouble finding compact wides for their A7/A7R cameras. There is some limited hope for a few lenses, but putting together a small, yet complete and flexible kit with consistent rendering (read: system, as opposed to several individual character-lenses) remains a challenge for now.
Putting a complete kit together right now is a challenge, but it shouldn\'t be that hard in 6 months. It is even possible to put together an excellent and flexible kit right now, but it would cost mega bucks. It would look something like:
SWA: Leica M WATE (covers 16 to 21mm at f/4)
WA: Sony/Zeiss E-mount 35 f/2.8 for landscapes and small size, Voigtlander M 35 f/1.2 for speed; Leica M 35 f/1.4 FLE for all around performance
Normal: Sony/Zeiss E-mount 55 f/1.8 for landscapes and small size; Canon nFD 50L f/1.2 for speed; Leica M 50 f/2 AA for all around performance
Short Tele: Leica M 90 f/2.5 for landscapes and small size, Leica M 75 f/1.4 or Canon nFD 85L f/1.2 for speed, Leica M 90 f/2 AA for all around performance
Tele: at 135mm there is the Leica M 135 f/3.4 APO, at 180-200 there are many SLR lenses for this system probably the best would be Leica R 180 f/2.8 APO, but if you do most distance shooting the Leica R 180 f/3.4 APO would be great too, and if you want small size their is the Voigtlander 180 f/4 APO which is quite nice as well. At almost 300 there is the Leica R 280 f/4 APO and you don\'t get much better than that, and at 400 there is the Minolta Rokkor 400 f/5.6 APO which is excellent.
So that would cover 16 to 400 all with excellent lenses and I have seen enough that I believe all of these would work very well. There is a bit of a gap between 21 and 35 in which it is unclear what will work well, but it is clear that the Leica R 28 f/2.8 v2, although not fast nor small will work well with the camera. So a system (and actually several kinds of systems) now is quite possible, but very very expensive.
An affordable system will be possible in about 6 months when the Sony/Zeiss WA zoom and short tele is available.
It would look something like:
SWA: Sony/Zeiss 16-28 f/4 (my guess, it is announced but not the specifics)
WA: Sony/Zeiss 35 f/2.8
Normal: Sony/Zeiss 55 f/1.8
Short Tele: Sony/Zeiss 85 f/1.8 (it has been announced and I think the specifics as well)
Longer Tele: Voigtlander 180 f/4 APO
Supplement this with some fast glass like the VM 35 f/1.2, the Canon nFD 50L f/1.2, the Minolta Rokkor 58 f1/.2, the Canon nFD 85L f/1.2 and you could have a very good and reasonably affordable system.
