Picked up Pentax A 50mm/f2 - free

Well, my father handed off his old Pentax ME Super with the A 50mm/f2 lens. Can't wait to try that out as well on my K10d and see how that works. He also has an old Yashika 35mm SLR (TL Electro X with 50mm 1:1.7 lens). Add these to my Canon Rebel EOS-G 35 with kit lens and 300mm zoom lens and mySony DSC-150 P/S and I'm building a nice little collection! I'm heading on vacation to Hilton Head/Savannah/Charleston next week so I'll be sure to take plenty of picture will all three of my Pentax lenses. I'll post the A lens ones in ths post when I get a chance. Don't expect anything spectaular as I'm just learning in depth dSLR photography.

It's a nice lens.

I hardly use mine anymore, but it's always close at hand.

I'm thinking of getting a reverse adapter and using it for some macro work.

I like mine well enough that I pulled the M-50/1.4 that I paid three times as much for out of my bag and put the A-50/2 in its place.

Main reason being that the only time I really use either of them is outdoor night shots with off-camera flash and I like being able to set the aperture through the viewfinder rather than counting clicks in the dark. If I want that length in the daytime I mount my Takumar 55/1.8, since I don't have to fool with removing aluminum foil and an adapter.

Since I haven't played with my A lens yet, what's this your referring to about aluminum foil?

It only applies to users of M42 (screwmount) lenses. The camera has a metering problem with M42 lenses, requiring a very large plus adjustment to the EV in order to get correct exposure. The problem can be greatly reduced by taping a piece of aluminum foil over the lens electrical contacts that surround the lens mount on the camera body.

Since I use M42 lenses almost exclusively, changing to an M or A lens means removing the foil and the M42 adapter first, then replacing them again later. Since that's a hassle I just swap out to a 55mm M42 lens instead. That's not practical at night, since when using M42 lenses one has to stop down the aperture manually prior to shooting, rendering the viewfinder pitch black and utterly useless for handheld shots. So in those cases I switch to the more modern M or A lenses, with which the aperture remains wide open until the camera closes it down when you press the shutter.

Okay, thanks, I've seen that in reference to the M lenses; but got confused and thought you were saying it included the A lenses as well. Thanks for the clarification.

I probably need to further clarify. It doesn't apply to M lenses. M lenses and M42 lenses are different animals altogether.

Sorry, that time was my error as I only typed M in lazyness without realizing it's an all-together different lens!

No problem. It's just important to tidy up things which aren't clear since people do come by at later dates and learn things from old threads. Don't want to leave anything behind us which could add to confusion instead of subtracting from it.
