Hey thanks for the help! I have a 50mm prime lense that I plan on reversing. Aperture control and auto focus is not really needed for me. It was something I was considering since I make buy the 100mm wr in the future which I would end up manually focusing anyway.
I have a pentax k5iis which Is the K-mount. I do not have the m42 adapter. I'm looking for a set of tubes of Amazon or b&h that I can get quickly in the mail. I ordered a reversing ring from Amazon sent out by adorama.
