            Make sure you buy authentic pentax (no tool needed and says Pentax and possibly Japan).

            Twists on and off smoothly. Lenses attach smoothly as well.

            Shipping was fast.

                Comments about Pentax Mount Adapter K:

                4 stars only because of the price tag. I think 50 i steep but after readiong all of the problems people have with the cheaper ones... I got this one. It is machined beautifully. It fits in nicely. I don't know why people complain about a little tool for taking it off and on... really? I use my fingernail and they are incredibly short. I can't imagine having a better working adapter for my K7 to m42 lenses. But I can sure imagine having a worse one. It's up to you, but I would recommende Pentax

                    Easy to install and remove without tools. I use it to screw M42 lenses onto my Pentax K-50. Allows the lens to focus to infinity.I originally bought one from my local Pentax dealer for about half this price, but that one required a tool, and even then was pretty difficult to install/remove. I returned it and bought this one hoping for better quality. This one is definitely better.

                      Comments about Pentax Mount Adapter K:

                      This mount adapter is a marvel of precision design and machining. My first thought when I saw it was, "I paid $[$]for this!". But when I started using it I discovered it was well worth the money. I recently changed my digital camera system to obtain sharper images. Because I am a geologist, often working in dusty, wet, cold, nasty conditions, I chose the Pentax K-5 IIs because of its rugged construction, weather/dust-resistance, and lack of anti-aliasing filter. This little device makes it possible for me to use the Takumar Super Multi Coated lenses (w/Pentax screw mount) that I have used with my Asahi Pentax Spotmatic (film camera) that I purchased in Japan in 1968. Those lenses have been a true treasure for decades, and it is very comforting to be able to continue using them with digital photography.

                        Comments about Pentax Mount Adapter K:

                        I only had a couple M42 lenses for my K30, and didn't originally want to pay a lot for an adapter, so I went cheap with one from @ that didnt' focus to infinity, didn't come out of the camera easily, left me frustrated and cursing often, and in general made me avoid using the lenses. Then I got hold of a Super Tak "fast fifty" that is a work of art - re-annodized and CLA'd by DCShooter (on pentaxforums - great guy). This is an Amazing lens and I didn't want to go thru the frustrations I had with the cheap knock-off, so I came to B&H and acquired the real deal. What a difference! WOW - the quality of the machining, how easily it goes into, and comes out of, my K-30, and having a full focus throw are well worth the relatively higher price! You might think you're saving money, and you might not care about the aggravation, but once you experience it - get the real deal and be happy with all that terrific old glass!

                            It is substantially more expensive than the other options, but well worth it. It mounts, and more importantly, dismounts with no tools, fighting or special technique. Lenses screw in smoothly and feel secure. I have found no problems with infinity focus on the lenses I have mounted (all Takumar).

                                  Glad to see these back in stock. I remove the clip and screw them on to my M42 lenses to make the lens a K mount. You have to be a bit careful because the will no longer clip into place and therefore it is possible for the lens to fall off you camera. But in practice the lens is snuggly attached to the camera and I have never had an issue with the lens coming unmounted.

                                    Comments about Pentax Mount Adapter K:

                                    It's a bit expensive, but it's reliable, adapts M42 lenses to my K-mount camera (K-r), and it doesn't jam like the generic one I had did.

                                    It's very strong, and very precise machining, capable of mounting a heavy Dietz 28-80mm f/3.5 zoom without problem. It can also be removed without special tools, unlike the generics.

                                    It's pricy, but it's the only M42 adapter that works flawlessly. I'd buy another one for another camera if I needed one.

                                    Only issue I have is that stop-down metering is horribly inaccurate with my Takumar lenses, but that can be fixed with a +3EV compensation or no compensation in Live View. Not a problem with the adapter, just Pentax's buggy code.

                                        I use the Mount Adapter K to mechanically link early screw mount lens (Pentax) to K mount flang found on digital SLR cameras like Pentax K-5.
                                        The adapter, bearing the Pentax brand fits well in all aspects; whereas, knock-off brand I have tried has mechanically jamb on my K-5. Recommend removing the adapter spring clip so lens and adapter can easily be removed together from digital body.

                                            There are some cheaper versions of this by other manufacturers, but most reviews recommended to stick with the Pentax model and I'm pleased I did. It was simple to install and remove, and had none of the issues I'd read about for the cheaper alternatives.

                                              It was a little bit confusing for me what adapter to chose but once I got it it is perfect, works very well. Now i can use my old lenses like my Super-Takumar 50mm 1.4 on my Pentax K100D.

                                                        Mounts flush with body, providing the proper flange distance. Better construction than the third-party units floating around. But, the construction is still not the greatest. I had heard rumors that these were brass, but that seems unlikely — the metal is rather soft, soft enough that I'm rather convinced it's aluminum. Could be SS, I suppose. Anyway, unlike the cheap adaptors that come with a tool, you need to find your own solution for releasing this from the camera body when you're done with it. The literature suggests a ballpoint pen tip, I have none of those around. Even if I did, I'm not sure I'd be comfortable prodding them around my mirror box… Point is, you need to find something at the time to put in the release, and the soft metal will seemingly get dinged up a bit from this. I don't think this will ruin it in time, but it's not going to stay immaculate for long. Still definitely recommend this genuine article over the cheap ones…
