DIY Ghetto Microscope

These are the remains of my old point-and-shoot Canon A80 from years ago. The part creative and part goofiness in me just couldn’t let these go to waste. I had to do something with them. I recently read about people attaching Holga lenses to their DSLRs to have some good ‘ol Holga fun. It got me wondering what would happen if I mount a compact zoom lens on APS-C sensor cameras. I just had to find out.

This is the result of some fiddling around with Nikon body cap, a glue gun, and left over pieces of the Canon compact. Now that this little lens officially became a Nikon f-mount I can mount it on my Nikon or my Canon Xti with the EOS-Nikon adapter. It even zooms in and out. How sweet is that?

Here is the result.
It’s not looking terribly handsome. And one has to wonder why anyone would want to do such a thing.

Here are the shots made with the silly frankenstein lens. The good news is that I can focus really close. I mean really close like 3/8 of an inch! It can almost serve as a cheap microscope. However, as you can see they aren’t terribly good looking. Also, at that focus distance you don’t get enough light between the subject and the front of the lens. So you’d need a tripod because you’ll be shooting really slow. Yes, the lens is crappy but fun. The same way go-carts are fun even if you drive a Bentley.

Konica AR Mount Lens on Nikon F-Mount

Interestingly, Konica AR mount bayonet is almost identical to the Nikon F-mount. You just have to remember to turn clockwise to lock (F-mount is turned counter-clockwise).
This Vivitar Konica AR mount wide-angle that I picked up from eBay next to nothing fits surprisingly well on the Nikon D90. Nikon’s long flange focal length – typically an undesirable feature for SLR enthusiasts – has turned this 28mm wide-angle into an effective macro. The result is surprisingly satisfying. It captures amazing close-ups. The lens is sharp and easy to focus. Of course, there is no focus-to-infinity due to the aforementioned flange focal length.
