Title M400+1.7X AF Bottom_Left
Description Being bored, I decided to see if the 1.7X would actually take a photo - or even touch up the focus - with my M 400-5.6. This series was taken wide open, Av, Shutter speed was 0.6 seconds on tripod, SR off, 2 sec mirror lockup, aperture obviously wide open. It will do fine tune auto focus given adequate light and contrasty edges. These were manually focused. Focus distance about 5.7 meters or a little less than 19 feet. This is, then , a 680mm f/9.7 lens equivalent.
