Originally posted by Art Vandelay II There's no perfect camera for everyone I suppose. However, since I personally don't care much about zooms I'm all for an ME Super sized mirrorless 35mm camera. As far as high end photographers using large lenses goes..I counter that with Leica. The cheapest lens they make is $1700, and every single lens they make is smaller than a FA31mm limited. They sale so many there is currently a 3-4 month wait because they can't meet demand. So I'd say there are a fair number of high end photographers that appreciate small primes. However, until recently we haven't had many options in the digital world. In fact, the NEX-7 is probably the first true DSLR replacement for a lot of us, and it is just now starting to ship.
As far as using large telephotos, f/2.8 zooms, etc. The one thing I don't understand is it seems no one thinks a large mirrorless camera will ever be made. Further, Pentax could design a modular body (seems righ up Ricoh's alley) about the size of a NEX-7, but design it so a vertical grip could be added to give it more heft when needed. You can always make a camera larger, but it seems Pentax has made a digital K-Mount camera about as small as they can; and they are still too large for some of us.
I wouldn't use Leica to prove your point. First of all, I don't think that Pentax could turn out a product with the cache that Leica has. I wouldn't even want them to. I, for one, couldn't afford it. People buy leica, not because of the optics (which are spectacular), but because of the name.
Of course there are lots of photographers who "enjoy" using primes, but if it comes down to every day shooting -- going out with the family, shooting a wedding -- most will take a zoom first and if they have space in their bag or they think they will encounter low light situations they'll take a prime as well. I think making a camera the size of the K20 is about the smallest that would work well -- whether or not it is mirrorless.
