Gap: ff = nice / 120 ... 140 mm 2.4 ltd VERY NICE, tele's 400 and + : no thank you: long may m43 prosper as I now have a gh2 which makes this part truly much easier for me. But not if you need fast performance ... room for improvement.
Mirrorless 1.5 crop is not so useful, I like the 2.0 crop very much. Maybe 2.5 would be nice, too. No this market is not yet overcrowded, in fact it is needy. For Pentax to join
. I, as an older woman, got used to the conveniences of the lighter and compacter system very quickly. Evf are great to use, mf is a jiffy, live view truly fun, especially with touch focus.
A x100 like all in one solution with all the goodies, of course, is always nice. But then I think 16 - 40 to be to limiting.
Frankly I have stopped buying other lenses for m43 for now, because I hope Pentax to show their brilliant new mirrorless system. The future will tell.
