Old Sigma lens for a Pentax camera: Can anyone tell me if I will be able to use this lens on this camera and if so, how.

Hi Ben, I just ordered this camera, but currently have the k100d. I did use an older lens with my k100d a while back and I had to press the a/e button for about a second to get it to stop down, the camera won't know what the aperature is set at, but it is still usable. I find dpreview.com is really helpful for those sort of questions. Just type in your query in the 'search' area and any discussion about it will come up. Good luck.

is sure that you can NOT mount a Pentax lens in a canon camera without an especific adapter, but I have not experience in adapters. Sorry!

No, it will not. It works just with a limited number of SIGMA lens. Have a look on the SIGMA website. It does not work with any lens of different company (Nikon, Canon, Pentax ecc.). Better: it can increase magnitude of 1.4 but you will loose both autofocus and automatic exposure. Frankly speaking, I use it (not frequently) together SIGMA 300 mm f: 2.8. The autofocus is not very precise, slow and the quality of the photos is not fantastic considering the whole amount of money that the lens (both) costed. Regards

If a lens works on a previous analog or digital Pentax (K-mount), it will also work on the K-3. With adapters, you can use even screw-mount lenses and other formats and manufacturers lenses too. Some restrictions regarding manual apertures apply, but the camera still works with them perfectly. As your lenses are digital ones, you'll have no problem at all.

I've been a Pentax shooter for over 30 years and one of the reasons is because all their lenses are compatible with all of their cameras - film and digital. If in doubt however, I would call them to confirm. Their customer support is really good.

Not sure why Amazon says it won't work. It will work, no question. Ive owned many Pentax bodies and lenses, and I'm sure it will work perfectly.

This is a silly thing to worry about. Older Pentax lenses were designed for film, which is an innately higher resolution medium at lower ASA/ISO speeds. A good K or M lens will still be good on this sensor, arguably better in some cases since the softest part of the image circle is cropped away.

Hi, thanks question. This lens can work for Pentax K-30, K-50. Thanks in advance.

Does anyone know if a Sigma DL MACRO lens that was used on a Nikon N70 can be used on the Pentax K-7? If so, how?

Yes the Pentax lens did work on my Canon camera with the adaptor. I was a little worried at first when i couldn't get it off of the camera but then i finally figured out there is a little metal strip that pushed in released it from the camera. Had me worried at first, and your Pentax lens will all be manuel.

If you buy a sigma 70mm for NIKON (mount) it will be 100% compatible and obviously you'll have the autofocus / I had the Pentax mount and the AF motor for that was inside the body not in the lens; anyways the AF for macro won't help at all, as for the portrait range it isn't fast for this lens

You should be able to get any kind of C-mount or adaptor ring for you Pentax. I had to buy one for my Nikon so this lens would fit. The only thing is it is a fully manual lens so you need to put your camera to manual due to it not recognizing that there is a lens even attached... this is a fun lens to use though. Amazing photos of the moon.

I have not been happy with the auto focus. I have used this lens with both a cannon T3 and a cannon 70D. The problem is it will no come into focus. I have contacted sigma asking if there is anything that can be done about this. I have not yet gotten a reply.

Matthew, Sigma has released information of a replacement lens which will hit the market towards the end of March. the lens is priced at $499 and boasts significant upgrades to almost every aspect of the lens. With that being said the price of this version of the lens has been slashed (lucky people like me found it for $289). I would consider your need for this type of lens. Most of the bad reviews come from earlier models of this particular version (matted black Vs smooth black). The defective lens's rightfully so get poor reviews, however the functioning models get high praise. I have tested the sharpness and autofocus and my unit is perfectly fine. I decided that $500 was too much for a new lens and $289 was a bargain for its older brother. If you look around you may still find that clearance price. I hope this helped!

Probably not. The lens linkage is specific to camera make. I would contact Sigma to see if they make a Sony configuration.

I purchased it for firmware updates which worked like it should. I only have the 35 so I would assume it is comp with that lens, but check the sigma website to be sure. Happy shooting :)

Question is non specific, but yes it will fit your camera, it does take nice pix. However, you may be referring to the auto focus and if you are go to the Sigma web site and look for the compatibility chart. Also if you go to the B&H; website do a search for this lens and looks at the specs..their site is very helful. (I have no affiliation with them I'm just a customer).
