   that is a beast of a macro lens! ha ha

   how does exposure work when using m42 lenses, when you’re in aperture priority and you adjust aperture does the shutter speed adjust automatically? or do you have to set everything manually

   I currently shoot pentax, but am interested in the new 7d, primarily for video work- and it would be nice to know I could use my pentax lenses on it

   I have a bunch of old Pentax M42 lenses left to me by my grandfather with his Yashica TL Electro, and this video convinced me to buy the adapter for my Rebel T1i. I only hope it works in video mode too! Great job.

   Well spotted! I keep referring to the 29mm as a 28mm – its just stuck in my mind now and can’t seem to get it right!

   Thanks for your comment!

   The second lens is a Pentacon auto 2.8/29. Not 28 mm, but 29. Good video though, well explained. Personally I prefer the non-flange adapter, I use the A/M switch to close aperture just before taking the picture.

   very helpful. a shame a watched it after i bought an adaptor of ebay and it didn’t have the aperture pinning thing need to return and buy a proper one then. macro rings work like this – the more you put on the closer ir will be able to focus

   This is great …
   This is great information!!….I have a Canon 20D EOS and i have a 70-220mm auto-zoom Pentax mount lens that I used on my old Mamiya 35mm…and have been told by a reputable camera store here in Canada, that an adapter for this lens would cost about $200. I suspect that they just want me to buy one of their lenses!! So thank you for this information, I will endeavor to find an adapter for my old lens, which I love!!!

   Bear in mind also a 2x teleconverter will rob you of 2 full stops of light, which means the exposure has to be 4 times as long which can be seriously slow.
   So in effect the min aperture of f4.5 suddenly becomes something like f8 or f10 or so.
   A 1.4 x teleconverter is only one stop less light difference which isnt so bad
   Also the image quality degrades quite noticeably on cheaper teleconverters.

    Very cheap compared to a digital lens.
    I like super takumars.
    The image quality on those is superb.
    I havent really tested out the other brands much

    pentax super takumars are top notch for image quality but everyone seems to have cottoned onto this as well so prices on Ebay are going up and up.
    Bear in mind most of the adaptors have slight differences in flange thickness etc so you cant get infinity focus with some of them.

    it is probably better to mount the adapter to the lens first.
