DA40 on K1000

I have a K1000 coming to play with, and I know I won't be able to control aperature on my DA40 ltd because it lacks an aperature ring, but I'm tempted to use it anyway since it's the only lens I have that will give reasonable results on full frame. My question is, what aperature will the lens have when mounted to it? Will it be fully stopped down (f/22) or wide open (f/2.8)? If the latter, I may go ahead and try it. Thanks....I spent some time searching the forum for an answer and came up empty.

Fully stopped down, unfortunately.

You can wedge something in the aperture lever to play. A small piece of cardboard or folded paper. Not great but I have done it. Once I had it small and secure enough it worked fine. At first it interfered from size or just fell out, neither is good.

You could pick up an M50/2 for practically nothing - and it will work nicely with your K1000. For a little more, get the M50/1.7 (still inexpensive but better).

Or get the M40 2.8. Can't have enough 40mm lenses!

I have the DA 40 XS and the M 40 2.8. I use the M 40 on cameras requiring an aperture ring, and the XS on the Super Program. The Super Program allows you to control the aperture from the body and makes a great, pocketable setup.

Super Program, DA 40 XS, Kodak Portra 160NC




MX, M 40, Kodak 400 (I don't know what happened with the developer)

Likewise for me. I acquired a perfect used M 40mm f/2.8 many years ago to shoot with my ME Super and later Super Program. It is a very nice little lens, built very well with very good performance qualities as builttospill excellently demonstrates. Eventually, I went all-out and also got the FA 43mm f/1.9 for my AF bodies, then with digital I added the DA 40mm f/2.8, as ZombieArmy says- can't have too many of these!

I decided to leave the DA 40 XS on my K-01 and instead use an M 40 2.8 on my Super Program for the distance scales and the ability to use aperture priority mode with the aperture ring.

Thanks for posting the photos. Id been looking for examples of the XS on film.

Thanks for the info and advice everyone. Just learned the K1000 is coming with an M 50mm/1.4, so I won't have to use the DA40 or buy anything (although I'm tempted to get an M 28mm/2.8 to go with it!).

Go and get a M 28mm/2.8, it's a great little lense and one of my favourites!

That M50/1.4 is a great lens. Get the background separation and nature right, and it will practically paint pastels for you.



The DA40 is too small and awkward for a K body IMHO. The true capital crime of photography is that the Pentax ME, the smallest and most pocketable Pentax SLR of them all, is incapable of working with it (because of the lack of an aperture ring).
