OMG....Thank guys so much! My 50-135mm is working again!
I did it with a Mac and a K5IIs and only using a SD card, and it took less time than it would have to dig out my Pentax USB cable. It worked with the first try.
Previously, I thought that taping over the contacts or removing the contacts all together (do not think of the movie Airplane!) would solve the problem, but it didn't. With the contacts removed, the camera still thinks it's an SDM lens.
Once again, thank you so much! I have golf shoot this weekend and I really need it for that. I had a golf shoot a month ago, and was able to slide by without it because the majority of shots were not the action shots.
This is my most expensive lens, and it's great to have it working again. It's part of a troika of lenses for my pro work, with the other two being the 17-50mm Sigma 2.8, and a 10-20mm f/4-5.6 Sigma

I FIXED IT! YAY!
I'm usually afraid of opening a lens (once I tried and springs popped out when I opened one).
So, being very careful, I opened it up, making sure that the area would prevent screws from rolling away.
After looking at it, and seeing how the parts worked and fit together, I noticed something really strange.
The circular piece that has the external Aperture lever, and the interior Aperture lever fits into the inside of the chrome mount similar to how the lens fits onto the camera body. It couldn't go on because a pin that prevents the piece from coming off, prevented it from being put back on. The pin is also an anchor point for Aperture lever spring. Unscrewing and removing the pin allow me to put the circular piece back on.
I think this is the first time I've fixed a lens. I wonder how the lens got this way in the first place? The pin would have to be removed and replaced for this problem to be created.

This is a push-pull lens. Doesn't that action suck in dust? This lens doesn't have much dust in it. I wonder if this has been used at all due to the problem, which might have come from the factory.

This lens looks pretty good, and the reviews agree. I can't wait to fully try it out tomorrow.

I picked up two items today that had problems with the Aperture lever.
One was a Promaster Spectrum 7 MC 2X KPR ($2.50). I was able to fix that with a pair of pliers.
The other one is a Vivitar (Cosina) 28-210 Macro Focusing Zoom 3.5-5.6 ($3)
Now, with this one the lever sinks into the lens body. Hold it upside down and you can see it when it falls into place, but during normal use, it retreats into the body. This prevents the aperture from opening.
Have you run into this before?

This is an Olympus camera power supply that works with the *ist DS. I bought it today. I saw one months ago, but didn't buy it, because I had just bought a no-name 6.5 volt PS. That one didn't work though. It must not have output enough power. Taking a picture with that connected, caused the shutter to act like a machine gun.
Today I was at a thrift shop that I rarely go into, and found this power supply

I just bought a *ist DS today. The Pentax Forums click counter says that it's at 7450.
I just updated the firmware to the latest. It now can read a 16 Gig SD card, but not a 64.

Isn't the KP the same price as the K3II? Maybe Ricoh want's pros to move to the K1 series?

I bought a very nice copy a year or so ago from a thrift shop for about $35. It was still in the box. I used it recently, and it's my favorite lens currently; I've been using it a lot. It's light, and the image quality is good enough so that a little post-processing makes them a lot better.

I tested a Neewer TT660 II that looked NIB at a thrift shop today, but I didn't test it on a camera. I got it home, and it did everything but flash on a shoe. Hours later I finally take the foot apart, and reseat the spring that connects the center pin. That fixed it for a second, then I had to open it up again, and solder the spring to the board.

Yesterday I bought a bag that I later learned was for a Ukelele. I thought initially that it might be big enough for my 200-500 Adaptall SP, but tonight I tried it out, and it's just big enough for the body too. The zipper just barely made it around the end of the lens. Also, I put a hole in the lens' cap to allow air to escape when taking it off and removing it. |

Thanks, guys! It was set to "Cross Processing". It must have been like that out of the box. This is my second Pentax digital, my first being the K5IIs, and I've never used that screen before.
