Homemade Lenses

Has anyone tried making any form of homemade lens for a EOS Digital?

A friend pointed me at a bodycap lens for his OM10 which gives lens-baby/holga style effects. I was just wondering what you could knock up at home using a body cap, some toilet paper roll and some old magnifying glass lenses or old reading glasses. Fancy a laugh?

I have seen pin hole lenses made from bodycaps. I mean to make one myself some time.

Well my first experiment wasn't too successful. I ended up having to use the kit lens for focus and holding my lens on the end. Pics and Lens available here:

Surfdan- I kinda liked your homemade lens shots. Very distinct look.
I made myself a pinhole body cap, but used way too big a drill bit and all the pictures are incredibly bright and way out of focus. Shots of colorful curtains looked like an acid trip.

P.E. My lens was made up of the internal bits of an old pair of binoculars and some masking tape! Hi Tek :D

The Loreo is a commercial pinhole-like lens.

Instructions to make your own can be found here.

Having spent £1000 on a 100-400 IS lens I don't really want to start messing about with old toilet rolls and magnifying glasses thanks! :D

I'm not forcing anyone to do anything @irbusfan. But for those who are a little bit more experimental/creative than yourself, I see no reason not to discuss it here.

Surfdan, you might really enjoy a lensbaby. Have you tried one yet? Lots of experimental possibilities.

I ordered a Lensbaby 2.0 and I think it ships Friday if they are still on schedule. WAHOO!

Anyhow, I really really like the tree shot above. Makes me want to build one with a spare endcap.

Any commentary out there on what size of drill bit to use? Do anything special to keep dirt out of the lens? The loreo is pretty cheap, and f/64 is nice, but I really like the blur from the homeade rig...

Here is some good info on how to make a bodycap pinhole. The example here is pretty advanced, and so are the results, but the idea is the same. Experiment and find what works for you and what doesn't.

Lenox Laser makes precision-drilled pinholes, which have two advantages:

1) The hole is a lot less ragged, which affects image quality quite a bit.

2) Since you know the hole diameter, you know you f/stop, and you can calculate very accurate exposures (you can get good exposures on very finnicky slide film).

Just use their online calculator to figure out what diameter you need, drill a hole in your body cap, and tape or glue the pinhole in. That's it!
