Will do GW!

Here's some shots I did today to test what I was hoping it would help with, macro shots. Excuse the really boring fly photo's, was the only thing I could really find on such a miserable day.

Seems to work pretty well for this, but upon checking some "regular" shots with the kit lens, you can see the focus isn't quite right. Will try to find the time this weekend to experiment with a tripod and fitting a shim or two. Hopefully the weather will be better next week for me to give it a good test outdoors, there's some interesting looking fungi starting to grow on all the old rotting tree trunks.

Something a bit more palatable for people, been messing around with it again this morning, and I think I have figured out the problem.

I need to position my eye higher than I normally do, and the issue of shadows on the micro prisms vanishes.

Went into the garden and spotted the neighbors cat sat on my fence, so decided to try it with f/2.8 as that should give me a much better indication of where the focus really was.
