I believe a genuine Pentax adapter can be had for around $25 either here on the forum or from someone on EBay. $49 seems a bit steep.

Keep trying. The genuines pop up here quite often and sometimes also on EBay. If all else fails, get one from B&H; make sure you go for the genuine Pentax K to M42 adapter. (I believe they are being designed and made from the same mold as the original ones but with a different metal these days—I prefer the old, original metal one that says Pentax and Japan on it.)

I have that very lens (bought from a member here) with that very pin and have no issues. In fact, that is my favorite lens; it gives me no grief whatsoever. I use the genuine Pentax M42 to K mount adapter that I bought right here from a member as well. Best two purchases I ever made.

I have a K-r camera and recently bought the K-to-M42 adapter from a member here on the Pentax Forum (a great place to buy and sell to other Pentaxians). It is an old, original K-to-M42 (screw) mount adapter, nice and thin. Easy. Take your lens off the camera body. Screw the adapter into the hole. Mount the Takumar (or other M42/screw-mount) lens onto the adapter. Comes off as easy as it went on. No screwdriver needed.

I get a black screen every now and again. But for the most part, the green button works for me. I don't use it all the time; in fact, I don't use it very much at all these days on my K-r, having become fascinated with what I can achieve through simply opening and closing my aperture in combination with turning my flash down to -2 and with using fast lenses (Sears 50 mm f1.7, Tak 55 mm f1.8). My conclusion is that using the green button is not an exact science, especially with a touchy camera. My K-r does not seem to like extensive use of the green button. Furthermore, if I "stop down" once, it works for the next several shots. Sometimes. Hmmmnnn ...

It might help to snap a photo first, see what you have (perhaps markedly over or under-exposed), then press the green button. I wouldn't press the green button right out of the gate ... So after setting your aperture to your best guess for the shooting conditions and taking a test shot, press the green button (you have now told the camera to adjust/compensate for the shot you just took). Next, re-focus and shoot; you should be "stopped down" now. Look at the shot in the review. It should be well-balanced.

I have a question that may have been answered already, but here goes: when you are using the green button to "stop down", how often should it be pushed? I have a feeling I'm doing it too much. For instance, I'll focus on my subject, push the green button, then push the shutter all the way to take the shot. Then, I'll focus on my subject (which hasn't changed or moved much) again, push the green button, then push the shutter all the way down to take the next shot.
Am I pushing the green button two times unnecessarily in the above example?
Sometimes when I do this, my viewfinder goes black (mirror lock-up?).
And sometimes, I get a very hazy shot.
So far, I'm doing better to just open my aperture and expose manually without using the green button.
