Just had a quick test with the lenses, due to the MASSIVE lens circle these things seem to generate the 5x4 area only really gets the centre of it meaning that its actually quite sharp and clear which is what I was aiming for - if they were smaller and of this design then the 5x4 area would have been nearer the edges which would have meant a lot of imperfections, will be interesting to stop the lens down.

250mm f2.2

125mm (ish) f1.1 - its a tad out of focus due to having to hold 2 lenses together and shoot using a manual lens lol but you get the idea, still quite a good image, slight bit of distortion.
