Roy - I actually focus with it wide open then stop it down as the last action before I shoot. Since I am shooting flowers I have time to do this and I know how many clicks f8 or f11 is to stop down (4 and 6 on my 28mm) . It's the one annoyance you have to live with to get sharp focus wide open, but you get use to it pretty quickly. Believe me, shooting closeups of flowers or insects, you need to stop down to get depth of field. Anyway, I can't wait for the macro lens to arrive I won on Ebay- Bruce

Ok Roy

here is a wide open shot, untouched apart from coversion from RAW and resize of my Vivitar 135 mm F2.8.

The second is the same shot only the lens is stopped down to about F8, both are in Av mode.

I don't think I will use the lens wide open, it looks terrible comapred to the smaller apeture shot.

As photos they may not be great but I learned something form the exercise about the effect of apeture on lens performance.
