The purpose of the calibration is to make sure that the AF system of your camera and lens is working together perfectly. You can use a USB extension cable but in our experience these can cause some problems with reliability and we wouldn't advise it unless you have no other choice. If you're using a laptop this won't usually be a problem, but if you have a desktop then consider this when choosing a calibration location. Your camera will also need to be close enough to your computer to be able to plug in the USB cable. The Target Distance Tool will help you choose the right distance, but here are some examples for common lens focal lengths. If the camera is too close to the target, the results of the calibration won't be as good for general shooting. The distance between the camera and the target is important for a good calibration. You'll need to attach the target to a flat, vertical wall and aim the camera at the target, so pick a height at which you can easily aim the tripod mounted camera.

You should have the software installed and ready to go, but if you're not in that position head to the guides below to help you get set up. To get my 50L dialed in I just did a LOT of shooting wide open, at objects with good texture and contrast, and eventually had an idea of where the AF was hitting the most in front or behind targetand adjusted accordingly.This page will show you what you need to do to run your first calibration. I plan to redo the L testing, this time from a correct, large distance.īasically, FoCal can't get a consistent reading and therefore can't make an exact adjustment. I didn't even need to use a tripod, remote shutter release, mirror lockup etc. I spent a lot of time doing indoor testing printed targets, computer monitor with moire patterns, Then I discovered that I get better results by hanging a large printed target on a wall in my backyard, and shooting it from realistic distances on a sunny day. I get pretty consistent focusing and have yet to notice much of the focus shift problem others talk about. I wonder what throws it off? How did you end of adjusting the 50L? That's the 50L for ya Don't blame the program, blame the lens. Which chart did you use afterall? Gear List. Interesting, I've heard great feedback from people on here which has me thinking of dropping coin on it but now you have me thinking otherwise. Anyone had better luck? Is there something I'm missing? F lickr.

So I waited until the next day and set up in my back yard in daylight the recommended environment.Įnded up using a printed free focus chart and settled on -6, which seems to give me the most consistency over varying distances and apertures. Took some real world shots and was not happy.
