The other day I was a bit bored, so I decided that I'd try and build a pinhole lens for my Canon T2i.
If you don't care about stuff like this, skip to the bottom, otherwise here is a summary of what I did.
First of all, you'll need the following:
A needle (the thinner the better)
A pencil with an eraser (optional, but it sure makes it easier to make the hole)
Thin metal (aluminum foil, brass sheet, etc. The thinner the better!)
A spare camera body cap
A drill
Some very fine sandpaper
A vise (also optional, but it will make drilling the hole in the cap easier)
And tape (to attach the metal to the camera body cap)
The needle/pencil combo, much easier to use.

I ended up using the bottom of a Pringle's can as thinner metals were not available.

The process is fairly simple, but a bit time consuming.
- Cut a small piece of metal out of whatever material you are using.
- Taking the pencil and /or needle, carefully poke a dent in the metal, you don't want it to go all the way through.
- Sand the very tip of the dent off. The goal is to make as small a hole as possible.
And that finishes the lens! Now for the mount.
- Take your camera body cap and tighten it in the vise.
- Drill a hole in the center of the cap. The size doesn't matter all that much, just make sure it's quite a bit bigger then the pinhole.
- Sand off the rough edges if there are any.
Finally, combine the two pieces by taping the pinhole piece inside of the camera cap.
And that's the finished product!
Below is a photo with the lens, without any editing or anything.
Of course it needs a bit of touchup work, and maybe a couple settings tweaked. But overall it's fun to play around with!

Now the part completely unrelated to the lens, or even photography for that matter.
If you are particularly observant, you may have noticed a new page of my blog up top called "
The Bookshelf". Basically it's a spot for me to put books I've read recently, and what I thought about them! I don't know how often I'll update this, but I'll try and update it a couple times a month depending on how many books I can find in Kenya!
Hope you all have great weeks!
