REMOTE CONTROL

Let's get one thing clear. Canon accessories are extremely expensive. There's no way anyone can afford to fully utilize their EOS 20D unless you're Lakshmi Mittal or Samerah bin Mokhtar al-Saadawy.

So being flat broke, the first step in accessorizing our Canon was acquiring a remote control with timing capability. The Canon model was $140 in 2005. The Heroine Heavy Industries model was $70. $50 of that was buying a cable with an N3 connector but it's still cheaper.

An N3 to T3 adaptor was destroyed to get the N3 connector.

The top switch engages the autofocus and light meter. The second switch engages the automatic shutter. The shutter is signalled once for mirror lockup and once for exposure. Delays for mirror lockup, exposure, and storage are configured using the dip switches. The third switch is a direct shutter release.

This works perfectly as long as it doesn't get wet.

LENS MOUNT

Let's face it. The Canon EF 200mm F2.8L that everyone has is really unbalanced but no-one on the internet has thought up a way around the $90 T mount. Now take a look at this.

That's a sheet of 1/4" MDF, some rubber floor matting, double sided tape, a #3 washer, 2-56 nut, 4-40 bolt, 5/16-20 blind nut, 5/16-20 bolt, 5/16 washer, and heat shrink tubing from OSH.

A 1/16" threaded rod and 3-32 collar came from Sheldon's Hobbies.

Don't tie it down too tight or you might bend the camera body.

This is a good solution for lens mounting until you have enough money for the T mount, but not a permanent solution.

PINHOLE LENS

Of course, a really pointless thing to do with your EOS 20D is make a pinhole lens.

It makes interesting effects with your sensor dust. You're better off with your 50mm F1.4.
