|NOTICE: Although the lens will fit physically, automatic diaphragm, auto-focusing, or any other functions will not operate correctly while using this adapter. In this case "stop-down mode" will need to be used when metering since the lens does not have the ability to have its aperture controlled by the camera body. You can shoot with manual mode or aperture priority mode.|
Customer Reviews of New Adapter Fits Pentax PK K Lens To Canon EOS Camera
Good Quality; Hard to Use4/8/2012
Definitely fits the PK lenses to a Canon T3. Sturdy metal.. The outside ring with the ridges would be good for gripping except that the one I received needed quite a bit of muscle power to get it to snap/lock into the PK lenses.. and just as much to get it to come off.. which hurt my hands from the outside ridges... And if you get it stuck on the T3 [i.e. lens and adapter separate so adapter is on the T3 instead of the lens] you have to be very careful & use something to pry the adapter off without damaging the camera].. so right now it is stuck on a PK lens and I don't think it will come off..which is fine since I'm planning to only use on the T3, but still requires me to buy more adapters for my other PK lenses. Maybe the one I rec'd just fits super tight.. but something to keep in mind if you are ordering and plan to use on more than one lens.
