Pentax 110 50mm F2.8 stopped down

Moving on from the 18mm lens I tried the 50mm lens. This was also taken hand held at 1/100th second (a bit ambitious given the 280mm 35mm equivalent!). The lens was stopped down using the 'ring binder reinforcement' method and mounted to a cheap eBay PTX 110 - P/Q adapter. The picture is straight out of the camera but resized.

Pentax 110 24mm F2.8 stopped down

The last of my collection of Pentax 110 lenses is the 24mm F2.8. As with the others, this was taken hand held at 1/100th second. The lens was stopped down using the 'ring binder reinforcement' method and mounted to a cheap eBay PTX 110 - P/Q adapter. The picture is straight out of the camera but resized.

The other ones looks amazing but this doesn't look stopped down enough.

Thanks. I used the same ring binder reinforcement hoop things on each lens. To be fair I suspect there may be an element of camera shake using that 50mm lens hand held at 1/100th, and I think there will be less depth of field with the 50mm too.

Yeah, but I still think it would be better stopped down just slightly more, quite typical for older tele lenses.

Ricoh XR 50mm 1:2 / OEM adapter

Fairly decent at 5.6. Didn't reset the shake number so it says 400mm in error.

Instead of wasting time hacking an old film movie camera to death to get the lens out so we can shove it through a hole we poked in a plastic body cap and try to take a photo with it, I want to know when someone is going to take a handful of sand and melt it down and pour it into a mold and polish it on a rock and make their own lens so they can duct tape it to the front of a Q and take a photo with that...

Check the index it may have already been done. I remember a toilet paper roll being involved somewhere.

You mean the guy that was stupid enough to make a macro lens with a bad lens, paper roll, tape and rubber band? Oh, now I remember, it may have been me.

Canon EF 100mm f2.8 macro

Well, I did it, sort of...The iris adapter now has a Canon receiver and a Pentax K mount. I could have used the $125 Canon to Q adapter on Ebay, but then I could not ever put the lens on a regular size Pentax camera.

Photo 1 is the iris adapter with the 4/3 mount that I needed to replace with a K
Photo 2 is the 4/3 mount removed, the K adapter is on the right with the remains of the donor lens in the background
Photo 3 is machining the K adapter to fit
Photo 4 is the completed unit
