Had Pentax 35 mm film camera. Given an ist DS digital body. Not doing something right, obviously, to use the old lenses. Told they should work. Figure have to do manually, not auto. Just need to know what to do. I do have one auto lense.......wide-angle. Works fine. Others don't. Would appreciate any help you can give me.

Thank you. Barb

    I install the lens from my 35MM camera but cannot get the camera to take a picture. Also, I great difficulty getting the lens to release for removal. Any ideas as to why the camera won't take the picture or why the lens is so difficlut to remove?

I have old Lenses that I use; you must set your lens to manual, Switch left hand front of body. That should resolve the problem.

I just purchased a Canon EOS Rebel K2 35 MM film camera body. What lenses are compatible with this camera?


The Rebel K2 has the Canon EF mount. It is compatible with any EF lenses except the EF-S series. It will also work with third-party lenses that are compatible with the Canon EF series.

You can see the entire current line of Canon lenses (including the EF-S series) at

Doesnt seem to work with the lens which was on my old K1000 which is a SMC Pentax-M1:2 50mm, serial number 5918334 any ideas?


Although your lens is an older manually operated K mount and will physically fit onto your camera, there are incompatibilities which limit the level to which it is compatible with your *ist DS.

Ignoring the really obvious difference that your lens is totally incapable of autofocus, the first real incompatibility is that your camera body has one of the "crippled" versions of the KAF (autofocus) mount. This means that it lacks the mechanical stop-down coupler/indicator used on the original K mount. The result is that your camera body does not sense which aperture the lens is set to and will not stop the lens down to the selected aperture when you press the shutter release. The full specification KAF mount maintains these old mechanical legacy couplings, but as most owners don't use older lenses any more the crippled KAF isn't an issue to most users and significantly reduces manufacturing costs. Crippled KAF lenses can still use some manual K lenses, but only the ones which have the A setting on the aperture ring and your lens pre-dates this development.

Your only realistic fixes for this are to either replace the camera body with a model supporting the full KAF mount (expensive) or to use later K lenses with the description SMC Pentax A instead of earlier SMC Pentax M. You'll still lack autofocus but as long as the lens aperture ring is set to the A position then it will work when the body is set to shutter priority and Automatic modes. There are far more Pentax A lenses remaining in good condition than Pentax M so you should have no trouble finding them, but because of their compatibility with later mounts you'll find that prices are somewhat higher.

Note that there is no adaptor which will allow you to improve compatibility between your present camera and the lens you have asked about.

I hope that I've answered your question, if so please take a moment to rate my reply. If not, perhaps you should add a comment to further explain in which way your camera doesn't work with your lens and I'll then try to assist you further.

*IST DS autofocus


Try using another lens, if this solves the problem you have a lens problem. If not the camera is the problem.

AV error whn pentax ist DL & Quantaray zoom lens attached


I've got the same problem. The problem is that the lense is loosely attached to the body. What you need to do is that when you see the Av flashing, press the lense of the camera to the body and twist the lense to the left a bit. This tightens the connection. You can then take the photo.

Cannon lenses


All canon EF lenses (and compatibles e.g. Sigma EX) can be used with both analog and digital  EOS-bodies. Depending on the sensor size (usually smaller than a 35 mm negative) a crop-factor due to the smaller field of view must be considered.  Example: Canon EF 50mm/1.8 lens used on a digital EOS (40D, crop factor 1.6) equals a 80mm lens (50mm x 1.6) compared to analog cameras using 35mm film. Some digital EOS-models can also use EF-S lens-series.

Why is my *ist DS eating my SD cards?!


I've used Sandisk Ultra II 512M cards, a PQI 1G and a Transcend 1G card (all high speed rated) in the *istDS. I've done about 1500 exposures now, many RAW, and have done several rounds of upload to my computer. No problems at all. These same cards work flawlessly in a Panasonic FZ10 as well. Either you have had a bit of bad luck, two defective SD cards in a row, or have a *istDS with a stuck or bad memory card controller. Try using the Reset command in the Set Up Menu, see if that helps. BTW, always format SD cards with the camera once before you start using them.

I don't know how to answer your question, since I haven't yet experienced that phenomenon. It sounds like it's just caused by the nature of the lenses used. Since you are new to the camera, I'll just warn you that it is not perfect in any way, but every function of it is very good, so the end result is amazing, and I might even say perfect. This is just the nature of the Pentax dSLR for now, and it seems that it's a Pentax thing in general. You'll find lots of dSLRs that can outperform the Pentax in one or two feature comparison tests, but if you lign up all the features of one camera and compare them with the Pentax you'll find the Pentax will beat any camera out there. It is just so well balanced, and each feature really is good enough, which adds up to a LOT. I'm sure somebody here will explain the problem you're having, and if you're like me you'll just make a few adjustments and be satisfied with the results. Post some shots too, that's an excellent way of getting feedback that will help you make the most of your Pentax. I wouldn't trade my Ds for any other camera out there even costing 10 times more.
