Originally posted by Ash Users have been talking about making a FF MILC just so that it can be cheaper than a dSLR. That's the idea of the K-01 which you are now downplaying.
I probably don't see a practical advantage in having fast wide angle lenses since they're chiefly used for landscape/architecture. I had the DA 14 for a while and found the f/2.8 capability not very useful. The DA 12-24 had much more versatility. That's just me but I wonder how many shots cannot be captured by having an f/4 wide angle lens.
I don't see K-01 as a MILC, for me it's more of a OVF-less DSLR with CDAF. So it got all the disadvantages of DSLR and MILC, without any real advantages of them. By sacrificing OVF, K-01 had a introduction price $100 less than K30. For most K-mount users I believe OVF and PDAF is worth more than that, so K-01 did not sell well.
I can see many advantage of having faster wide angle lenses, for instance when shooting indoors, or shooting close up and getting better separation of background.Why do you think most ILC system have a fast "24mm" lens?
Another advantage of lenses needing less glass is that they are cheaper to manufacture, which hopefully lead to lower price on lenses.
