likely the best K-x combo
In terms of quality, they are just as amazing that deliver quality in a small body. I always get amazed especially on the quality from DA 40mm limited as it is the thinnest of the trio in 21/40/77 and yet the IQ is excellent in the prime and its close focus is quite good at 0.4 meters.
I can pretty much mount my DA 40mm limited and use it as a normal lens on both my K-x and K20D. The K-x has the edge over the K20D in smaller size and coupled with faster AF in the DA limited lens, I can hardly find a reason not to like the 40mm limited. And as many have noted, I have tried the DA 40mm limited on film body with Pentax SuperProgram. In program mode, I can pretty much use it with no issues on vignetting in the corners. With the SuperProgram, the 40mm is a really compact pancake waiting for light traveling. I have few pictures using DA 40mm f/2.8 limited with hood mounted on Pentax SuperProgram in P mode with film scanned by a lab
on film with Pentax SuperProgram
And I tried out the DA70mm f/2.4 limited over the weekend on my white K-x along with Pentax DA 21mm f/3.2 limited, the performance is good and I have not run its course for more uses, but I find both the high ISO capability of the K-x will work quite well with the DA limited primes . Even wide open shots in 6400 is pretty acceptable to me. I am casual shooter in image quality but it really warms my heart to take pictures of my boys not having my flash handy and the shots were done in indoor lighting and my boys are not standing still for the shots.

Impressions & Notes
- Though all DA limited primes are small, they are quite outstanding in image quality.
- The DA 40mm f/2.8 surprises me with smallest in size but quite outstanding in real usage.
- Both the DA 40mm and 70mm can be used with FF film bodies such as Pentax SuperProgram in the Program mode or if a body has provision in aperture change in body, it will work with DA 40 and 70mm in aperture change. Capable film bodies with aperture control in body include many but I have used Pz-1 and P3n with good handling and results
- Though slower than the FA limited equivalent, they are the best to be used with the Pentax K-x if your objective is compact in size and lightweight in traveling
- AF is found faster in DA 70mm f/2.4. In the indoor shooting, I do find the lacking of AF to lock on target quickly and hence missed a number of shot opportunity
- The DA 21mm f/3.2 limited will have imaging circles when used on film bodies.
- The DA 35mm f/2.8 limited will work with film bodies better than 21mm limited but not as perfect as 40mm f/2.8 limited. I will report back in using DA 35mm f/2.8 with a roll of film for test reports.
- ISO 6400 are usable with the default medium NR setting. I have not tried but I think someone shooting it in raw and use Noise Ninja or Neat Image will have better outputs than my jpg with little to no post processing.
- Grain in the 6400 is appealing for black and white conversion
- I pushed the DA 70mm to its knees in f/2.4 and iso 6400 and results are reasonable but one will get better pictures with less pushing to the extremes.
- I dearly miss the AF-C switch in my K20D. I shot all test shots with AF-S and I think I will have more keepers had I changed to AF-C easily when the scene dictate the changes.
- Use of flash at the right scenes may be better suited than relying on the high ISO as the grain and a bit of detail loss warrant the use of bounce flash.
