I have an old pentax camera (at least 10 yrs old) with SIGMA lenses, are they still compatible with this camera?

Great camera, and any K-mount lenses will work (manual lenses will work with our AF)

If you lenses are K-mount bayonet style you will have no problems. If they are the really old screw mount style you will be out of luck. I can not recommend this camera enough. If you are looking mid-grade this is the one. If you have the money to spend upgrade to the K-5 IIs, or maybe the K-5 II. I am intrigued by the removal of the anti-aliasing filter, it is supposed to result in outstanding photos if you get the setting correct....good luck....

I have a Pentax older that yours and all of the lens seem to work fine. I have both Sigma and Tamron lenses You know that with the older lenses it won't be weather resistant. It's only WR with Pentax WR lenses.

Yes they will work on this camera. However if they are not Auto Focus lens that function will be disabled.

Generally the answer is yes. However today i discovered that I have a Sigma 28mm lens that mounts on every pentax film camera I own, but that lens will NOT mount on my Pentax K-x DSLR. I am trying to find out why, and if that can be fixed, and I am close to ordering a K-30 myself, and am curious if it will mount to that Sigma lens!

All PENTAX 35mm lenses will work with the PENTAX DSLRs. Non-PENTAX brand lenses are not tested for compatibility with our DSLRs. In addition, use of other brand lenses on our DSLRs may result in the lens becoming stuck on the camera, which could damage the camera's lens mount and void your RICOH/PENTAX warranty. Some older RICOH lenses such as RICOH-P, lenses marked "KR" or "PK-R" or lenses with a metering pin projecting from the lens mount are not compatible with PENTAX DSLRs. PENTAX bayonet mount lenses work naturally and without the purchase of any adapters. Older PENTAX screw mount lenses will require the purchase of a Mount Adapter K (Part#30120, approx. $30). In the Menu under Custom Settings, set "Using Aperture Ring" to "Permitted" for lenses that have aperture rings, when the aperture ring is not in the "A" position. The K-50 and K-500 use essentially the same settings with older lenses: PENTAX A-series lenses (lenses with an "A" setting on the aperture ring), can be used as manual-focus lenses in all exposure modes on a PENTAX K-50. Early PENTAX K-series, M-series and S (screw) mount lenses without auto-aperture control (an "A" setting on the aperture ring) can be used in Manual exposure mode using stop-down metering and manual focus. This is the exposure mode which will give accurate exposures when using these older lenses on our digital SLRs. If older lenses without an "A" setting on the aperture ring are used in Av (Aperture Priority) Mode, an exposure error may occur. Note: Using PENTAX S (screw) mount lenses on a PENTAX DSLR requires the use of a Pentax Mount Adapter K.

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.

Yes.. If you buy a lens with a PK mount it will work on any Pentax camera that uses the PK system. This includes all Pentax cameras going back to the start of the PK system (1980s?). Some features of newer lenses will not work with older cameras that don't support the new features, but the lens will still work in manual or non-auto-focus mode with older film cameras. All Pentax digital DLSR cameras that use the PK mount support the features of the new PK lenses. The Pentax Q cameras do not use the PK mount, but you can buy a Q to PK adapter (not the best set up, but it will let you use your PK lens on a Q system camera). Yes..

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.

Yes. The nice thing about Pentax lenses is that even the old screw mount ones will work with any Pentax dslr, and all K-mount lenses will work on any dslr body.

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

Possibly; check with Pentax Service and Repair Dept. 1-800-877-0155, Chandler, AZ

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.

Yes, i have so much fun to use all my old lenses (K mount) but first you need to get the right adapter for about $30. You better do some research on pentax forum. They have many tests on different lenses.

Probably, but I'm not the expert. There's a table of lens compatibility on Sigma's web site. I also spoke with a Sigma tech Rep --- very helpful.

Yes, the *ist takes K-Mount. An advantage-if you still have lenses for old Pentax film cameras-is that you can use them on the digital Pentaxes. Besides Pentax lenses, other makes with K-mount will fit.

Hi,I would say yes without any problems, i have used mine with my Pentax K5 and a sigma 70mm-300mm lens on many occasions with out any issues, since the B Grip has the added support section that sits against your thigh it can be used with this set up with out ant problems.

This adapter is for Pentax Lenses. I'm not sure if the sigma you are asking about has the same mount as Pentax. Probably not.

With the proper adapter there should be no problem but I have no experience adapting Pentax k lenses to Canon bodies.

Completely interchangeable. Only older Sigma lenses may not work fully, but those lenses aren't worth keeping anyways.

Hi SammyC - Pentax uses a Bayonet Type System, Called a " K-Mount "...that is unique to Pentax and also Sigma Cameras. You can find the filter thread size by looking up the lens on Amazon...they usually have the filters available just below the write-up on the lens.
