I think it will be interesting for Pentax to be ahead of many others in planning a 16-50 and 50-135 f2.8 lense. This will be equivalent to 24-75 and 75-200f2.8 in 35mm film.. which mean not only wider angle, but better coverage for the lense.. 2 lenses is all I would need.. but just wonder what is the price of the lense like...
