      For manual aperture lenses only

      I purchased the Bowers screw mount to use old Mamiya, Tamron, and Tokina screw mount lenses on my 5D mk II.

      The product is fine and does what it says...Read complete review

      I purchased the Bowers screw mount to use old Mamiya, Tamron, and Tokina screw mount lenses on my 5D mk II.

      The product is fine and does what it says but much of the convenience of shooting digitally is thrown out the window and the experience will be akin to shooting with film.

      The most critical thing to know is that your lenses must have manual aperture control or they will shoot wide open by default and you will have no depth of field control.

      To be sure, remove the lens from the camera and turn the aperture ring. If you see it open and close, you're good.

      1) QUALITY: The Bower adapter is a durable well- machined item.

      2) EXPOSURE CONTROL: Still Mode: No in-camera metering. Video Mode: Auto exposure works normally (5D Mk II).

      WORKAROUND: If you are shooting digitally, of course you can simply snap exposure tests or rely on a handheld meter.

      3) INACCURATE LIVEVIEW: The DSLR live view will be inaccurate and appear underexposed in many circumstances so you will depend on the viewfinder for focus and composition.

      WORKAROUND: If you have a video function on your DSLR, you can also hit record at which point the 5D II, for instance, will correct the exposure and you can compose. Useful in low light situations. You can then just trash the video clip.

      4) NO DEPTH OF FIELD CONTROL WITHOUT MANUAL APERTURE CONTROL ON LENS: My Mamiya lens has this switch so the aperture is controllable on the lens, my other two lenses do not and so they always expose wide open.

      If you don't have this feature on your screw mount lenses then they may be of little use on your Canon, unless you always like to shoot wide open.

        Comments about Bower Lens Adapter Canon - AF Camera Bodies to Pentax Lens Screw Mount:

        I contacted your help desk and they gave me the information on this adapter. It is great, I can now use the old Pentax screw mount lenses that were collecting dust. Granted, it takes a bit of work to get the lenses to get great pictures, but to use a lens that I have owned for over 25 years is great, brings back a lot of memories, and gives me more lenses than I had before. Also, your personnel were fantastic, they were helpful and extremely knowledegable.

            Comments about Bower Lens Adapter Canon - AF Camera Bodies to Pentax Lens Screw Mount:

            I recently acquired a box of very nice old Pentax lenses. This adapter works perfectly to attach them to my EOS 5D. Of course I have to shoot manually, but that just goes with the territory for these old lenses. Some reviewers mention the adapter gets stuck on the lens or camera body, but that has not been a problem for me. If it was, I would try a little judicious polishing on the mating surfaces of the adaptor. I'm sure that would fix the problem. It would be better to fit too tight, rather than too loose. My lenses fit to the camera very securely, with absolutely no play.

                  works great ! Using my old Super-Takumar 1.4 from my Pentax SP. Wanted to try some night shots with my Canon 7D and needed more light. Now using Liveview and manual focus. Just zoom in to check the focus ...having fun.Also using it for some video. Think I will be digging out my other pentax lenses and experimenting. I had looked at the Sigma 1.4 and it had great reviews but this adapter was less than $ and the Sigma runs around $.

                    The product fit perfectly.
                    For those of us who started photography more than 40 years ago and now own a video capable DSLR this is an excellent solution to affordable prime lenses.
                    I went with T mounts for my old Spiratone 85mm and 400mm but the M42 for the Pentax 50mm 1.4 and the 28mm wide. It's not that the kit zooms are bad it's just that a prime is called prime for a reason.

                      I inherited a bunch of old Pentax screw mount lenses from my dad and wanted to use them with my 7D and other EF mount cameras for cinematography. This adapter enables me to do that! It works great! The build quality is great and it just works. It's a cold mount, so you can't do autofocus or anything, but I shoot manual anyway, so that's not a big deal for me. I'm really happy with the product, it brings new life to these great old lenses.

                                            This adapter allowed me to use my 70's lenses from my Fujica ST701 camera: Praktica srew mount 42 mm diameter by 1 mm Pitch thread. I can now use my old Bushnell 70-220 1:3.5 Macro lens on Canon Rebel XTi easily. Just screw on the adapter on the old lenses and lock them in the Canon body. To remove the lens and adapter push the release button and twist as your normal lenses. Unfortunately the first few trials, I had to remember that my old lenses are not auto-focus. It works well in Av and M modes. I would have bought this adapter sooner had I known.

                                                I wasn't paying attention when I ordered this as I needed an adapter for a Vivtar Bayonet Mount to EOS body. This was for a screw mount. Even though it was sent back I do have to say that it looked very sturdy and well machined. Gets a good rating for the product can't rate my stupidity!

                                                  This adapter is PERFECT for mounting threaded vintage lenses to your canon EOS body. The adapter is very heavy duty, I have no fear of loose lenses like you get with most cheaper priced mounts. A TOTAL MUST HAVE FOR VINTAGE LEND JUKIES!!!

                                                    Bought seven of these guys and all of them deliver. I've attached them to some old Pentax Super Takumara lenses and they all work beautifully. 1000% satisfied...

                                                      This product allows me to use my quality lenses circa 1970s, on my new Canon T3i. This adapter has no downside, other than auto settings no longer work, but I want to be in control anyway. Low cost; buy one for each legacy lens.

                                                        Back in "the day" (mid-60's to mid-80's), I was totally involved with Pentax gear, mostly screw-mount lenses and accessories. I dropped out of serious work in photography until last year when I bought a new Canon EOS DSLR with a couple of lenses and discovered the joys of digital imaging. The problem was, I had some fine old lenses and macro equipment that wouldn't fit the new camera. The Bower lens adapter has put my old and much-loved Super Takumar lenses back to work and allows my bellows unit to again make macro photos really up close and personal. I like it so much I may buy another just for the convenience. It is well made, fits with precision and was an inexpensive way to put my old friends back to work. It does what is asked of it and that is all I could wish for.

                                                        I thought I could never use my old Pentax-type screw mount lenses again after I went Canon Digital. The other brand of adapter was listed for [$]-- insane! Now I can use my Vivitar Series 1 70-210 Macro lens which along with my Mamiya/Sekor 55mm portrait lens (aperture rating 1:1.4) paid for a lot of wedding shoots and a few contest winnings over the years. Shooting a lot of film with manual settings means the only drawback to this adapter isn't really a problem. All-automatic exposure and auto-focus makes you lazy!

                                                            I bought this adaptor to mate with the adaptor I got with my spotting scope. The only problem was that the threads on this adaptor were course thread and on the spotting scope adaptor were fine. I was still able to make it work.
