I NEED one of these.

OK.

I want one of those.

A lot.

Sadly, they cost many of your earth pounds and so I'm going to have to save and buy one later. So, in the absence of sponsorship from Canon (Mr Canon, if you're reading I am still open to offers), I decided to try something a bit different. Andrew suggested a reversal ring, and after convincing me it wasn't some sort of weird proposition and it wouldn't hurt I looked them up.

Essentially you use a little adapter ring to mount your lens on your camera backwards. The reversal ring comes with the appropriate lens mount for your camera plus a thread of your choice. I'm not sure I understand the physics of it, but essentially it allows near 1:1 (macro scale) image capture depending on the lens you use.

You can pick one up on Ebay for about a tenner.

Well, since it was cheap and a bit of a giggle I picked one up and had a play. The version I bought had a 52mm thread on  it to fit my 50mm F/1.8 lens. Honestly, the only reason I picked this one was because it was to hand when I did the ordering. The ring (with appropriate thread size) will work fine on the kit lens as well I reckon.

Here's some results.

None of these shots have been tweaked in any particular way in order to show you straight out of the camera what I achieved in about 5 minutes. There has been no cropping at all!

For the cost of a pizza (I'm a big lad, I like my pizzas man-size), it's a nice toy and there are only two real downsides that I've seen with it.

1. You have to live in manual world. you lose the connection to your lens when its reversed so the aperture just defaults to whatever the lens rests at and can't be adjusted that I could see. You'll need to set shutter speed manually, though at least the exposure meter on my 400D kept working which helped a lot.

2. You have to focus manually. Now this doesn't sound that bad, but look at those shots above again. Depth of field is razor thin, and I mean razor. You're probably playing with millimetres in focus and given the lens is mounted backwards it can be tough to do any adjustment. I found it was simplest to just move camera (and head) backwards and forwards.

OK, lets be honest. this is never going to replace a dedicated macro lens (and Mr Canon, if you are reading I'd love a loan of the 100mm one mentioned above). But, if you want something different to try it's not a bad way to spend ten quid and an afternoon. I've put it in my kit bag. You just never know...
