I bought an adapter from Ace Photos. It was made by Bowen and was engraved with M 42 to Pentax K mount Adapter. I placed it on the lens. Easy. Then it would not fit my k20d. It'd drop in; it would not turn much; it would not click. I was faint of heart.
I called them and they were clueless as to the equipment so I sent it back. Before packing it up I figured I'd try again. Nope. Then I figured I'd try getting one of the back lens caps on to see if I could. I was more willing to twist the cap harder than the camera. :ugh:
And it did click in! Thought I was on it until I tried to get the cap off!
Yep. Stuck.
If it wasn't for the flex of the plastic it would have stayed on. Wow! Then what?
I need some more guidance here! I want to use an old Sear lens now but more want to be in position to use M 42 lenses later. I read something about removing a spring clip that is on the rim. Is that what it takes?
Then there is this issue:
Originally posted by OrenMc You can leave the adapter on the lens if you so wish. Just remove the spring lock and off you go. Then get yourself a k-mount cap for that end.
I don't leave it on the lens becasue I have a couple lenses to use it on but I removed the spring anyway because it was kind of a pain to remove from camera.
As I understand it these are not to stay on the camera! How could that be? The question would be more about how many of the adapters you want to get. One per lens to make the changing easier? A few? just one and take the time to spin it onto each lens?
TIA
Ok I read directions on how to do this!
Before removing the adapter, you must screw off the lens. Next, use a ball-point point pen (or fingernail) as explained in the instructions to disengage the spring in the adapter and twist it off, pushing counterclockwise with the pen.
Warning: Certain non-Pentax screw mount lenses will get stuck when mounted on a Pentax auto-focus camera body and they can only be removed by a repair shop. Those lenses have a protrusion which will snap into the autofocus coupler hole or into the screw heads on the rim of the Pentax bayonet and thus lock the lens on the camera. Do not use any non-Pentax screwmount or bayonet lenses before you have verified that they have no irregular protrusions on the rear.
And now it makes more sense about why people think it "stays on the body since it doesn't simple come off the body like a regular k mount.
Would have been nice to have directions with the product!
Still is confusing. Guess I'll have to buy another one! Try again. But which one?
