I suppose it depends what the priorities are. Some people think that compact and reasonably priced 35 and 85mm f1.8's are basic staples of a good system whilst others would prefer a 50mm and others would prefer SOTA f1.4's. Some prefer zooms and of those some would prefer f4's and some f2.8's. I suppose it would be ideal if there was a set of lenses to suit everyone and the Sony system has filled out a lot to the point that we have most things now and indeed we have reasonably priced compact 50 and 85mm f1.8's, they just haven't so far given us a 35mm. I'm sure they could do one if they decided to. I just don't believe it's impossible due to some strange limitation of the mount... Stick an adapter on a Canikon DSLR f1.8 and it'd still be smaller than the Sony or Sigma f1.4's.
The glaring omissions for me are the 35mm f1.8, a longer macro (150mm?) and I'd add a 50mm macro to that little list, one with a decent focus system as the one I had was rubbish and went straight back.
PS.
Talking about glaring things the Nikon Whatsit has a max shutter speed of 1/2,000 with EFCS. I'd find that unacceptable as I don't want to go back to fitting and removing ND's because of shutter speed limitations. I hope they either cure the shutter shock or somehow get around that limitation. Given the choice of swapping my A7 and AF 35mm f2.8 or MF f1.4 for a Nikon with a compact 35mm f1.8, if they have one, and that limitation I'll keep the Sony gear and live with the lenses I have.
