First few goes with this adapter which can either be used as an odd electronic extension tube or as I was using a lens reversal adapter that maintains full electronic control of the lens. Tried it with the kit lens. One oddity I noticed during shooting with ETTL flash was the shots were around 1 stop overexposed at my normal flash settings. I think this is because the reversed lens has an aperture around one stop wider than the set aperture. This means needing to shoot with the aperture on the lens about 1 stop smaller than you would normally at any mag and also setting the FEC on the flash about 1 stop -ve to your normal setting.
Mag range with the kit lens was just under 1:1 at 55mm and about 5:1 at 18mm. I hadn't expected to get focus at that focal length but the focus distance was 25mm in front of the adapter ring.
