We all want lightning fast auto focus and that is the enemy of accuracy, so if we had slower auto focus we probably would have more accurate auto focus too. The reasons for this miss in focus accuracy are mostly twofold, one is speed and the other is in the nature of the Phase Detecting auto focus system used in DSLRs. And this is what Reikan Focal will help you with among some other features if you go for the Pro version. The thing you’ve done is to move the plane of sharpness a little further to the front or backward, so the subject you’ve aimed at is in perfect focus and thereby also is at its sharpest. By this I mean, you can’t use the fine tune and make the lens magically sharper, like swinging a magic wand over it. If there isn’t anything faulty with the lens, the lens will always be as sharp as it can be at some point in distance from the camera and lens. We’ve all heard that this or that lens is not sharp, or some use manual focus “to make the lens sharp” or maybe even some who has done some AF fine tune report that the lens is much sharper. Means at this time only Nikon and Canon cameras are supported by Reikan Focal. With Canon it was introduced by the 1Ds Mk II and I think all including and above the 50D and on are supported. I would condense it down to: computer software that helps you determine the right plane of focus via in-camera auto focus adjustment.ĪF fine tune with Nikon was introduced with the D300 and D3 in 2007, and all but D3000 and D5000 series are supported. You connect your camera to the PC with the standard USB cable and start the software.įoCal guides you through the correct positioning of the camera and target, then you can run any of the tools at the touch of a button.įoCal works with Canon and Nikon DSLR cameras that support AF Microadjustment/Fine Tune – see the Supported Cameras page for more details. Reikan FoCal is not very known by DSLR users, so what is it all about? Copied from their info:įoCal is computer software you install on a PC or Mac, and a special target you attach to a wall.
