M42 lens to Pentax PK K Mount Adapter Ring infinity focus guaranteed K20D K10D K200D K-M Review

Average Reviews:

(More customer reviews)I got this adapter from Rainbow Imaging and it works great. This adapter will maintain infinity focus as can be seen in the pictures as well - adapters must fit within the camera mount and be flush with the body to achieve this - any adapter that sticks out from the body will lose infinity focus.
The adapter is a simple metallic ring with an added retainer clip that keeps the adapter from getting off the camera. The key that comes with the adapter allows you to keep the retainer clip pressed against the adapter, so you can remove the adapter from the camera. It's also useful when mounting the adapter, to help tighten it.
Some people worry about the clip getting stuck inside the camera mount, so if you're concerned about that, another alternative way of using this is to unscrew the retainer clip, then tightly screw the adapter onto the M42 lens, then mount the lens as a regular K-mount lens. The risk with this approach is that the lens may come off if you are not careful, because there is nothing keeping the adapter inside the mount (the lock that works for normal K-mount lenses cannot work for an M42 adapter).
I've used the adapter both ways and I'm currently using it with the retainer clip on. When removing the adapter just follow these steps:
1. Don't panic
2. Use the key to keep the retainer clip pressed against the adapter
3. Try to not push the key too much towards the mount - try to just grab the tip of the adapter, so you can turn the adapter without the key getting in contact with the mount
4. Turn firmly, but don't apply excessive force - it's not needed and may lead to scratches
For the price range, I doubt there is a better alternative to this adapter.

(More customer reviews)Edit--- Since this review I've gotten another to find out there are off brand ones going around. True fotodiox adapters are much better than the off brands. They will have the name on the side and screw in before needing to be tightened by the Allen key. The no name off bard I have has already been striped by switching between SR and 4/3. I do not beleive this will be a problem with the proper ones. Just a heads up- touted as used may be off brand.
------------------------------------
Great product. I have the 40-150 4-5.6 and have been unhappy with the amount of unacceptable blur I get at the 5.6 mark. This product for less than $20 allows me to use a nearly impossible otherwise 170mm 1.7 (when you adapt a 85m f/1.7 Minolta MD on a 2x crop frame). A 200mm f/2.8 becomes a 400mm f/2.8 for less than $200, used. The ability to use super fast, super long Minolta lenses on the 4/3 system is a great advantage that makes up for the infamous lack of affordable 4/3 lenses.
For those who fine the lack of tactile feedback on digital disappointing because of their familiarity with 35mm film will find themselves right at home with an adapted MD/MC. An adapted lens works in manual mode by adjusting the shutter speed with the toggle wheel on the body and turning the aperture ring on the lens accordingly. I find the E-520 meters after a test shot is taken and you can stop up or down accordingly. I can't speak for other models.
Be warned that with some lenses the diaphragm pin is not entirely accounted for by the adapter so you will have to mount the adapter just slightly less than locked. With the tight fit and metal mount this has never been a problem for me. It is as snug as can be. It also take a minute to get used to mounting. It needs to be wiggled into place. But again the benefits far outweigh the trouble.
Overall I suggest this product to anyone who wants to make use of their old lenses, add lenses to their kit at bargain prices or fully utilize the advantages of the 2x crop frame to get some of the longest, fastest lenses possible. It's also worthy to note that tilt shift lenses (a glaring omission from the 4/3 system) can be mounted from many systems with the adapters that this company manufacturers. While Olympus currently makes about 24 high quality lenses, your options are open to a new world when you consider adapters. Being complacent with our limited choice is no longer a sacrifice we have to make with the 4/3 system. I believe the discerning photographer will be very happy utilizing and paying for Minolta manual focus lenses on their 4/3 body with this adapter.

Average Reviews:

(More customer reviews)There's really nothing more I can say about the adapter. If you do your research and understand what this is, then there should be no surprises and no worries about the usefulness of the adapter. I bought a used Olympus E-P1 for cheap and I've got a ton of nikon lens that I was hoping would work with this adapter. And they do. Sure, everything is manual including the aperture (hell, you dont even get traditional "stops" with a G lens), but who cares? This isn't a magical adapter that gives you the same experience when you mount a nikon lens on a nikon body. This adapter is for people who want to experiment with photography and discover a deeper understanding about what it means to move reflected light through glass and onto a sensor. If you have nikon lenses and a micro 4/3ers body AND you want to learn more about photography, get this adapter.

RAINBOWIMAGING Nikon Lens to Micro 4/3 Four Thirds System Camera Mount Adapter, Olympus PEN E-P1, Panasonic Lumix DMC-GF1, GH1, G1, G2, G10, (RainbowImaging Adapter, MSRP 24.99) Review

Average Reviews:

(More customer reviews)I got this so I could use my few remaining Nikon lenses, slide copier, etc. on my GF1. The reviews on the more expensive one said that it wouldn't let go of the Nikon lens, so I went for this one. It works ok. The lens release button does not work smoothly, but it works. It lets go of the Nikon lens when you push (or really slide) the button. It has a more difficult time letting go of the camera body, but if I am patient, it releases ok, without forcing. It fits well, with no slop. Bear in mind that focus and aperture will be manual.

Average Reviews:

(More customer reviews)This thing is amazing. I was looking at some $700 macro lenses, but thanks to this I no longer need one.
Because there is no glass in between the lens and sensor, the image quality is not affected at all. What you get are clear, crisp macro images.
I experimented with this (see the product pictures) and was shocked at how good it worked. Yes, everything must be done manually - exposure, focus, etc. But it's definitely worth it. You can get VERY close to your subject - I was only about one inch away and the focus was great.
Thanks to this, I saved $700 and now can take amazing pictures with my kit lens (18-55mm) and Nikon D40.
Some tips:
To get the best results and focus the absolute closest, zoom your lens out as wide as it will go. The pictures I have submitted were taken at 18mm.
Use as much light as possible. I used a simple flexible desk lamp to light my subject, and still had shutter speeds of about 1/2 a second.
Use a remote release - you need to reduce vibration as much as possible.
When focused VERY close, all the dust on your lens and camera sensor will be visible in the photo. You can take it out fairly easily in Photoshop, but it is best to keep things as dust-free as possible.

By mounting the lens backward on a camera body, you can create amazing macro images.It is extremely fun to turn you lens into a macro lens.
