The auto thing-a-macallit on Amazon says this lens won't work on a K20D. Is that true?

this works fine on the k20d. I have it on my k20d and it is a fine lens. great to have if you want a good prime lens.

No, that's not true. You can find the answer here. http://photo.net/pentax-camera-forum/00YDTO

Yes, my old K-mount lenses work fine with my K-50. However, you'll have to experiment with exposure settings and manually set the f-stop and shutter speeds (plus manual focus of course). But it's a great advantage if you already have some old high-quality lenses in your kit.

I got mine on Adorama. Its M42 to K mount for Pentax. Get a good quality one other wise it might get stuck to the lens or camera.

Works very well with a K3. Used it almost exclusively on a trip to Hawaii as a walk around lens and it performed well. https://www.flickr.com/photos/ted_beilby/sets/72157646102761802/ to see some of the shots.

I don't have a K3 (sadly), but I do know that this lens is fully compatible with my K5 and K5IIs. Therefore, I am confident that it is fully compatible with your K3. Pentax seems to be a company that avoids incompatibilities between cameras and lenses. I have often wondered where this advice came from - no idea, but I believe it to be either incorrect or based on criteria of which most of us are unaware.

It's a DA (made for digital) lens. I have used it on the K20, Kr, K5, and K30. It is a great lens, in my opinion, and has endured the test of time.

I have this lenses and it worked very good on my K500 PENTAX. Which is almost the same as the K50. This I hope is some help.

The mount I purchased was the Konica AR mount to the Nikon D800 and it works fine in manual mode or aperture priority mode. Also Have a Pentax K20D digital camera that has an APS-C Size chip that I use with Fotodiox Pentax 6x7 lens adapter to the K 20D. This also works well in the manual mode and aperture priority. It should work with your camera if you select the adapter that has a Canon mount to what ever lens you have. Also Some APS-C cameras do have the same mount as full frame Digital cameras.

It also says it will not work with K-7 or K-5ii. This is a newer lens made for today's Pentax and Ricoh DSLR's. I wouldn't trust the assistant. Go to the Pentax site to determine if it will fit. I believe we can trust those who responded here.

Yes. It will work with any of the K series. This is my main lens because of its versatility.

Yes, they do work. I have a Pentax K20 and it works just fine. You have to go into the software of the camera to insure that the camera picks up the lens.I just looked up the steps on the internet to do it. Also, like Fred stated make sure that your camera is the K-mount not any other mount or it will not fit or work.

If the lens is a Pentax Bayonet mount it will fit this camera. I use several manual lens from the 1980's on my K20d. The manual lenses will of course only function as a manual, and you will have to set aperture and focus yourself.

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.

Yes! I just bought it for my K30 and it does work. You can set the camera to auto-focus when you press the remote and that works, too. I have had no problems with it, using it with the K30 and the DA 18-135mm lens.

Yes, but. I also have a K1000 and I have put the lenses on my new K500. They do not operate in the automatic mode setting (on the side of the K-500). I set the lever to MF instead of AF.S or C and they work well. Obviously, the aperture as well as the focus is manual.

I don't have a MKII, but as other people confirmed it will work. Just one thing to keep in mind, since on a full frame body, you'll see dark corners for sure then zoomed out all the way. PS can improve a lot, but try not to zoom to the extreme 17mm. The best about this lens is sharpness. Bokeh effort isn't that great. Landscape should be one of its best uses I think.

As others have said, it'll work. Be aware, though, that the K200D's image sensor area is smaller than the 35mm film area. The apparent focal length is 1.5 times the 35mm focal length. This means a 12mm lens will appear like an 18mm lens.http://en.wikipedia.org/wiki/Crop_factor
