> Very nice, Dave. That 400 is a great asset. It is, although I do struggle with it at times. When the AF gets it right I get some great images. I was lucky with this one as I'd been in such a hurry I'd forgotten to pay attention to the settings and it shot at f/6.7 so depth of field was not in my favour. I remember trying to calibrate the focus of my lenses soon after getting the K5ii but gave up as the AF system just wouldn't quite focus consistently. If I focused on the target a few times in a row it'd always come out slightly different, which made me wonder what was the point of calibrating it. I seem to remember my target wasn't perfect but I never quite got around to having another go with a better one. I do wonder it if's simply a mechanical limitation of the screw-drive mechanism.
