question
Will this adapter depress the aperture pin and allow you to do stop down metering on any M or A lens
Google pentax k mount adapter m42 stop down and read the article in the Pentax Forums titled How to stop down an M42 on a K-mount camera . In a nutshell, there is no aperature link between the m42 lens and the K mount camera. You must focus (for brightest view) fully open, read the meter at wide open, stop down to the aperture you desire, calculate the speed, set it and take the picture. It's been a while but if you do a depth of field preview stopped down, that should give you your shutter speed. Anyway, it is a small price to pay to allow you to use some of the excellent old glass out there.

question
I bought both an unused original Penac adaper for my K5II to use with tele Takumar M42 lenses but it wiggles iomce in the comera. Bought a chinese adapter, it is more stable but with rough machining. Is stil stable once in the camera mount? Or is wiggles like the knes i have.
The Pentax adapter will wiggle when in the camera without a lens attached, because it is designed to get pulled tight into place as you screw the lens in. With the lens fully mounted, camera and lens should be steady and solid.

question
Will this allow focus to infinity on Takumar 200 f.35?
Yes, it focuses to infinity on all my my m42 lenses. Very well made. You only need one. It stays in the camera and the lenses screw into it. Excellent gear.

question
Is this a genuine Pentax adapter?
I hope you get other responses. I only used it a few times and not with me now while I am travelling. It seemed to be well made and fit nice with both the old Super Takumar lens and the K5 body. I don't recall any stamps that indicated Pentax but could have been.

question
I tried out this adapter on my K3II with a Pentax Super Takumar 55mm lens (M42), and for the life of me I now cannot remove the adapter. Any tips/tricks? Thanks!
With the 55 mm lens removed, one of the open slots on the adapter has a flat metal (spring) tab that needs to be compressed before removing adapter. Use a jeweler's screwdriver or something similar in size, Hope this was helpful.

question
I have a Pentax K200D with some old Pentex K100 lenses, and Sears and Ricoh lenses that worked on my Pentax K200D. I'm just starting out, playing around... Will this adapter work with my Pentax and non Pentax lenses on my K200D? Thanks!
Hey! I use this adapter on my K-3 for some of my old manual lenses with m42 screw-mount and it works just fine, no problem with focus on any of the distanses.
