Seems most of his issues are not getting the lenses he wanted in time, which is a temporary thing. Unfortunately, the high demand for the new lenses and the Japanese earthquake put things behind schedule. Another major issue is the menu system which is legitimate.
I still think mirrorless, even FF gives you more flexibility to go light. The cameras got bigger because they added IBIS, even so they are still smaller than a FF DSLR without IBIS. How big would a stabilized DSLR be? It is apple to oranges in that respect. Yes, you can use stabilized lenses on a DSLR but you can also buy an A7 or A7r and use stabilized lenses on a SonyE and be significantly smaller and lighter.
The biggest issue I have with Sony seems to stem with their decision to put the 36mpx sensor in the A7r. I don't know if this was due to an effort to directly take on Nikon or to just push the technology. That sensor requires a more "telecentric" DSLR lens design vs. a rangefinder lens design. The lenses could be made significantly smaller if designed for just the 24mpx or 42mpx sensor. Now they seem to be stuck having to also cater to the A7r sensor. The 36mpx sensor should have been used for an A99II.

The compromise
And, having mentioned compromise, I should explain the great compromise which has made the entire Sony E/FE system much larger than it needs to be.
It’s all down to the A7R 36 megapixel sensor. This sensor, more so than the 24 megapixel full frame, requires a very telecentric lens design. That is, more like a DSLR lens, despite the slim A7 series body. In order to perform acceptably with this sensor, the FE lens range could not be designed to be as small as a rangefinder system equivalent, or to take full advantage of the 18mm mount to sensor distance.Brian Smith, whose images are great (not cheesy portraits) but whose technical info clearly comes via Sony PR, says this: “Mirrorless camera design has allowed Sony’s lens designers to place larger than normal lens element close to the body”. Actually, they don’t, as the design of the extenders will tell you. They’ve used a stronger degree of telephoto construction in the long zoom, allowing a smaller than normal rear element and they have taken measures to move it further away from the body – and this is a general trend. If you want to see what a properly small 85mm f/1.4 looks like try a Carl Zeiss Planar 85mm f/1.4 ZE in Canon mount – 72mm filters not 82mm, 570g versus 850g and really solid all-metal manual focus. The mirrorless bodies do provide a zone from around 16mm to 42mm from the sensor surface which can accommodate the rear of the lens, and can’t ever be used on a DSLR. But Sony does not make full use of that and can not do so because of the microlens, filter layer and structural characteristics of the A7R sensor.
Despite this, the flexibility remains. Tom Bricker stated he may give the excellent Voigtlander 10mm a try before making up his mind on Sony. That combo is materially smaller than a DSLR wide angle counterpart. In fact, since 10mm is the widest rectilinear FF ever made, right now there is no DSLR counterpart. I think future hope for smaller lenses made reside in the third party realm.
Sony's A7r decision is now haunting them as the demand for more "pro-lenses" such as the f/2.8 zooms increased. They are as big as DSLR lenses because of the A7r. This is not to say that one cannot make a small FF kit with Sony. Using certain primes one can. The 35mm 1.8 is very compact. The 28mm f/2 is small and light and at a good price. The system allows you to be a big lens "Pro" one day and a light traveler the next. Obviously the A6000/6300 even more so. Unfortunately, it could have been even better.
