Will this lens work on the Pentax K20D and are there any limitations?

The K20D is a KAF2 mount. The DA 18-135 is a KAF3 mount. They are compatible. However, as a k30 user, there may some limitations that I am unaware of. There are K20D and DA 18-135 users on Pentax Forums who may be able to answer your question on limitations. http://www.pentaxforums.com

It will work with full functionality on ALL Pentax DSLR camera bodies. It's an excellent, economical upgrade to the basic kit lens.

Bill, I have a K20D also and tried this lens on it - the distortion was apparent at 18mm indoors.. I only tried the lens on the camera.. never used it as I did not get all the proper paperwork nor a lens shield with it... so I returned it the next day to Amazon for a full refund.. only because of the seller.. not the lens itself.. I'd also say.. read as many reviews on it as possible before buying..

Yes this will work with the Pentax K-x. All the latest Pentax DSLR (except the 645D and Q series) use the same mount. So it will fit and function as it should (as well as Sigma programming allows). You may not have some of the exif info that you would have used a Pentax made lens but beyond that you shouldn't have any problems.

Yes, it will. Any Pentax bayonet-mount (K-mount) lens will work with any Pentax DSLR.

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.

I know it will probably work with the K50 since it is the upgrade for my K30. I would suggest you Google pentax.com with this question. I have a feeling it probably will work but I don't want to lead you astray!

I have used the old K1000 lenses (pentax 50mm lens it came with and an off brand telephoto) on my pentax k-3 with no issue. It is all manual, so I have to take a guess at metering, and of course no auto focus, but it works, it mounts and produces nice results. You will have to have knowledge of manual metering to produce the results you want.

It works perfectly with my Pentax K10 and it is my understanding that it should work with the K5 and all other Pentax DSLR's made since the K10..according to Pentax. I actually bought 2 for this reason.

Ah, then you should be pretty much at home with the basic functions of the K200D. The LCD also displays setting information.BTW, if you have any screwmount lenses, make sure to get the official Pentax adapter since the 3rd party adapters may lose infinity focus. Also get some good NiMH rechargeable AA batteries (like Eneloops) and a charger.

Is this lens compatible with my PENTAX K100D SLR? Will the auto focus work? Will I be able to use the scene function of my camera?

Well.... technically yes. After all, "Pentax claims that all their auto-focus cameras are backward compatible with K-mount lenses dating back as far as 1975 without need for an adapter." But there are major trade offs. The camera cannot read the set f-stop of K and M series lens. You won't be able to take advantage of the autofocus options. You may need to manually set aperture. You'll have to compensate for the smaller digital chip size as compared to 35mm film. But technically the lens is will work. You'll likely get better results from upgrading to a lens designed for use with the digital camera. The K-5 II does offer full manual control options that will let it resemble the Pentax ME. Well... except for maybe the film advance lever and rewind crank.

Other than I know that all Pentax lenses are supposed to work with any of their bayonet mounts I don't know. I know it worked with my K100 digital. To my great delight, I can use my OLD Pentax lenses that aren't digital with my digital Pentax--they just don't read what the computer part is saying in the camera. I have gotten excellent photos using non-digital and digital lenses with my digital Pentax.

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 beauty of Pentax DSLR's is that they will accept all K-mount Pentax lenses ever produced. I myself have a 25 year old manual focus 50mm M f/1.4 lens I use on this camera.

I have tried it on my K10D but mostly use it on my K-7. Never had any issue with it.It is one of my favorite lenses...

Hi, may be is a mistake, I have my Pentax K-3 with this lens works perfectly

If it's a K mount , yes. Mine came with the correct mount for Pentax. I have a K20D and a K5.

I don't have a Pentax digital camera, but as I understand it they should have the standard K-mount. Be careful of the Ricoh K-mount lenses that have an extra pin that can get stuck on the digital cameras so that you cannot easily remove the lens.
