Most previous tests were done by Carlo Lastrucci, not by me (with the exception of the 24-90mm, published in Spotmatic No. 30, October 2001, that we made together). Then I commented Carlo's pictures on Spotmatic magazine. No, we usually don't do focus bracketing, since most people in most pictures don't. I'd appreciate your further comments on this. Carlo's tests were done focusing with MZ-5 autofocus, with the exception of the latest comparison (35/2 FA vs. 31/1.8 Ltd, published in Spotmatic No.34), where focusing was manually adjusted by looking at the split-image in MX viewfinder. My test about the 24-90 was done with MZ-S, autofocusing on subject (either infinity or mid-distance) always going farther away from a closer subject (hence reaching focus from close distance). I was thinking of doing the same this time. Suggestions are also accepted. Bye, Dario Bonazza -------------------------------- http://www.dariobonazza.com
