Well, then you've got a much bigger lens. The idea behind such a fast 50-135mm telephoto zoom lens with APS-C is to effectively give the same usage as a DFA 70-200mm f/2.8 lens on a FF camera, but in a much more compact package. A very good concept! That is the spirit in which I use mine and I love it. I'd much rather use this lens on my KP than to get the DFA 70-200mm f/2.8 for my K-1 II! In fact, I hope if a PLM version does come, and it probably will, that it will be the same design, indeed the same lens, because it is that good. When they replaced the SDM DA* 16-50mm f/2.8, the new PLM version came as a much larger lens! But in that case, it was needed to put in better optics for better performance. The DA* 50-135mm f/2.8 performance is just fine as is- the SDM AF is the ONLY problem!
