[QUOTE="Blade Canyon, post: 551801, member: 15302"] Count me in with Osantacruz and Geoffc, Focal software is not any better than the manual methods, and it's a pain to set up and takes a lot of time to make the adjustments. In the end, its calculation is usually very close to where I had the setting already. I've shot down rulers and I like shooting along a bookshelf to see which titles are most in focus compared to the focal point. The fastest manual method to fine tune AF for certain lenses, however, is the no-shot method. Put the camera on a tripod, set the lens to manual focus, zoom in on Live View, and achieve the most perfect focus you can get manually. Then switch off Live View, look through the viewfinder, and push the shutter button down half-way to see if you get the green focus light. (If you are set up for BBF, I guess you have to hit the back button.) If the indicator light says the shot is in focus, then the AF and the actual focus are in tune. If the focus indicator gives you an arrow instead, start adjusting the AF fine tune (without changing the focus or moving the camera) until the green light comes on. That's it. Someone told me the green light is much more generous when the camera body is manual focus mode, so that could be a big flaw in this method, but it has worked well for me. [/QUOTE]
