Re: DA 40mm

The DA 40mm lenses are supposed to be exactly the same optical formula as the old M 40mm f2.8, with more modern coatings.  I can't say whether that's true or not, I have an old M version and didn't see any particular reason to duplicate it with an AF version.  On the other had

Re: DA 40mm

Thanks Larry, that's just what I was wondering whether I should get the 43 for better performance or the 40 for smaller profile. I wondered about how the K-1 would dominate the size issue anyways. Now I think you have answered my question. I've been using the 31 limited in this function, bu

Re: DA 40mm XS on full frame SLR

Late, (still working on the backlog of old posts), it's not surprising that the XS or for that matter the regular DA 40mm would exhibit soft corners on film, so does the M 40mm f2.8, they all share the same optical design after all. On 4/2/2013 6:09 PM, Mark C wrote: I found the corners

Re: DA 40mm XS on full frame SLR

I found the corners to be soft on film as well. Less so when focusing close than when at infinity. But it covered most of the frame well. Mark On 4/2/2013 9:55 AM, Zos Xavius wrote: The 40XS has clearance for the mirror. Rice high posted samples from a 5dmk3 and it didn't fully cover the fram

Re: DA 40mm XS on full frame SLR

I was not aware of that. I've used the XS on both an Mz-S and Pz-1p without problem. The first try on the Mz-S produced very good results, but that camera relies on using an aperture ring to shoot aperture priority so I did not do a systematic test. The Pz-1p controls are like the K-5, K-7, K-1

I recently stumbled on a Pz-1p at a good price and bought it - I doubt that I'll use it much but it is a great camera and I do still shoot film. Took it out to test and tried the DA 40mm XR that came with the K-01 on it, just to see how it looked. I tried this earlier on an MZ-S but si

DA to me would mean that it's optimized for the digital camera sensors, and might not return the best results at corners and edges on 24x36mm format. That does not mean that it would be unusable, and it might in fact work quite well. It's not hard to make a 40mm lens that is well optimized for th
