You need to disassemble your new one , screw that bit on then place the outer bit on. then those three screws force the mount up aginst the lens ensuring the correct registration distance. Also before you tighten them make the lens align properly on the camera. And yes it is easily the best solution for a T mount lens.

New adapter will be delivered to me tomorrow. It is not an expensive item ($10), rather for test.

Hello everyone sorry i was away and didnt have much access to the internet. i ended up buying a super-paragon 28mm that had the official ring for 40 euro so now i got another m42 lens . i am now trying to figure out how to depress the aperture pin, im gonna experiment on the cheap lens and then go for the helios one. I havent noticed any problems with the adapter threads although ive noticed that it gets a bit stiffer to lock the lens on the camera. Other than that its been pretty good so far. Removing the adapter from the camera was an issue at start but i found out a way to take it with a small paperclip. thank you all for the answers!

A common issue with some of the Helios lenses is light leakage around the base. You might look at this thread.Preventing M42 adapter light leaks and dust ingress - an easy solution! - PentaxForums.com

Not to beat a dead horse, but I don't have light leakage through my kipon adapter even with a lens with a base so narrow that it exposes the electrical contacts (and it depresses the aperture pin and focuses to infinity).

I havent noticed any problem like that on the helios but the lens that the adapter came has some light problems like kinda flares from other sourses of light from the frame.

According to comparison of conducting and non-conducting (black plated) adapters described in:
TESTS: Plated vs Painted (conducting vs non-conducting) lens mounts on K-r: whats t - PentaxForums.com
I made some improvements:

I removed the black anodized coating to make electrical contact for pin 7 and ground.

Yes especially with the Helios 44 to 44-2 models and any other lens with a small base light leakage is an issue. Some of the flare examples in the Helios reviews are obviously from this source. It is another advantage of the non-infinity (flanged) adapters in that they don't leak the light.

Not sure why you are doing this. The lens is totally manual - the green button would have worked fine. No matter what pins you short out there will be no stop down metering.

I just tested it with conducting and non-conducting mode. Result is the same. You have a right.
