General Brand ABPKS overview

  • 1Description

This adapter allows a "universal screw mount" type lens (Pentax M42) to be mounted on a Pentax K-mount type body. Although the lens will fit physically, automatic diaphragm (AE metering), or any other functions are not retained using this adapter. In this case you will need to meter in "stop-down mode" since the lens does not have the ability to have its aperture controlled by the camera body.

General Brand ABPKS reviews

Pentax-K Body to Universal Lens Adapter is rated 2.8 out of 5 by 20.
Rated 1 out of 5 by from TERRIBLE PRODUCT COST ME HUNDREDS This adapter is a terrible product and I want to warn you against selling this. Within the first 24 hours of using the adapter, it malfunctioned and broke on my camera mount and was permanently stuck. I tried several pro camera shops and no one could remove the adapter. I had to send my camera back to Pentax for a full service. They also had to clean tons of metal shards that flaked off the adapter into my camera body. This was a terrible experience for me and I am definitely not reccomending the Bower adapter. Infact through this experience I have learned that hundreds of others had the same bad luck I did with this adapter. ...

Rated 3 out of 5 by from Great price, poor build quality I used this to adapt my old M42 camera lenses to my Pentax K10D DSLR. It allows me to use my lenses and it works as advertised. The downside is that it is rather flimsy. There is a flat spring held down by a small screw. The screw came out inside my camera body, along with the spring. Luckily, nothing got scratched. The head of the screw was not well cut, and was difficult to put back with a jewelers screwdriver. But hey, it's $. You could get one for each lens you want adapted, and just leave it on. And I do like the old lenses on the new cameras.

Rated 3 out of 5 by from Caution: Pros: Works well. I use it with a 55mm chinon lens, and it works like it's supposed to. Cons:The small screw that holds the spring steel lock screws into the threads of the adapter. I buggered the first few threads of my lens before I figured out what was going on. After removing the screw and spring, worked fine. No problem with adapter coming loose in the body, but the lens un-screws easily, and could pose a problem with heavy use. Just be aware. Conclusion: Does what it is advertised to do.

Rated 1 out of 5 by from Horrible Jam - Don't Use it. Easily mounted on my Pentax ME Super. However, when you find out that the M42 lens you mounted cannot properly stop down with this adapter, you'll try to remove it from the camera. Forget it! You won't get it off. This thing is jammed in my camera and I can't get it off, even with the so-called special tool that is provided with the adapter. So, now I have useless Pentax ME that is mounted with an equally useless and unremovable adapter.

Rated 4 out of 5 by from The only thing missing is an removal key This is a proper m42 to K-mount adaptor; the entire adaptor fits into the k-mount barrel so it doesn't act as a impromptu extension tube. It's latching, so it will *not* come out unless you really want it to (my regular camera rig is a Pentax *istDS, this adapter, and a 55mm f1.8 super-tak lens. When I go on long bicycle rides, the camera goes into a pannier bag and bounces down the trail with me, and it has not come undone ever.) There are two small defects with it. The first, which is not very much, is that the screwmount side of the adaptor is about 30 out of true, so the aperture ring is twisted to the right side of the barrel (and the manual/auto diaphragm switch sits directly under the bump that contains the built-in flash unit) and the second is that it doesn't come with a removal key, so I have to use a screwdriver to release the barrel latch so I can twist the adaptor off the lens when I want to use one of my K-mount lenses.

Rated 1 out of 5 by from Adapter can get stuck on lens This adapter is grouped with the cheap M42 adapters. However, this one has a screw which holds a flange onto the adapter. It's not easy to put in. However, I used it fine on my M42 200mm. Then I put in my M42 135mm. When I tried to unscrew it, the thing got stuck. In the end I had to cut it off. Major pain. I hope B&H stands by their products, good or bad and refunds all my money.

Rated 4 out of 5 by from works as advertised I use older Pentax screw mount lenses. There is no limitation in focusing. Distance imaging remains sharp with this adapter. It must be screwed tightly onto the lense. Otherwise it may remain attached to the camera body. Removal is sometimes difficult.

Rated 1 out of 5 by from Did not work. It is not made like the original Pentax adapter that I had and cannot find and was easy to get in and hard to get out. The 55mm Takumar lense would not screw into the adapter very well.
