Pentax Q DIY Pinhole lens

In short, I tried to make a Skinkpinhole lens for the Q at a much lower cost.

Aesthetically it has that slim look that just suits the Q well.



I heard rumors that the machining work is a bit subpar with loose tolerances and I actually think that Visualdarkness Inc once again went with paper in the construction, the good news is that it's a sturdier paper and it's actually taped this time.





I think it's pretty much on par with the Skinkpinhole shots that are out there, except for the wonky OOF highlights, but that's not saying much and I doubt that you can see a MTF with the lens. My very unscientific (it's way too hard to see a target) focal length testing tells me that it's between 9-11mm, probably at the lower end.

This pillow was the best target for FL testing due to large colorful areas so that I could measure by something.



This one makes me dizzy.



Yes, it's actually a lamp.



A flower or a hugging seamonster?



Can you guess the lenses?

LOL BTW the OOF highlights in this one are quite interesting.

Sigma 50-500 and DA*300?

Better add this one to the adapted lenses thread - other mount (Q) before someone beats you to it.

At first I got a double image due to a bad hole so I consider the OOF points a huge improvement.

Much smaller.

Wait 'til I post my second DIY lens for today! It's a way more interesting one, although less sturdy and won't go in you pocket together with the camera.

Neat idea. Haven't done a pinhole on the Q. Need to try this myself. Will probably use tin foil.
thanks
