Originally posted by Ben_Edict Ken, that's an interesting notion. So can you be more detailed with your experiences Zeiss versus DA or M versus DA? That would be great! I mean, there are a couple of current Zeiss lenses available for Pentax which might be worth a try and the M are quite cheap, compared to the DAs.
Thanks

Ben,
No direct experience with the Zeiss glass but the samples I've seen on this forum and dpreview make me wish I had the funds to buy them. The build quality is reported to be outstanding.
As for the M, K, and A series Pentax glass, take a look at these tests.

From personal experience I'll match the M28 f 3.5, K35mm f3.5, FA 43mm f1.9, any K or M 50mm including the incredibly cheap 50 f1.7 against any DA* lens. There are others that will also equal or surpass the DA*'s but I have no personal experience with them.
For zooms I'd say the A 35-105 and the A 70-210 are equal to DA* in IQ but they are manual and not weather sealed. They will, on the other hand, be able to use a FF sensor to it's fullest advantage when it shows up.
I'm not saying DA*'s aren't good, I'm saying there are alternatives for a lot less money and their own advantages.
We haven't even touched on the advantage some old screw mount lenses have. There isn't anything in the DA* line that can do what my 85mm f 1.9 can do.
