That was probably more information that you wanted.

The value you choose will depend upon how you usually use the lens. Unless you have a Canon 1D, you usually have only 1 AFFT value that the camera will accept. Case in point - zooms with different AFFT values at each end of the range. But whether or not you actually need the program is an open question.ĪFFT is still as much an art as it is a science, and there's always an amount of compromise involved that's not objective. You can then apply his tuning value detection program to the images and arrive at a result with direction documentation of its accuracy in the image itself. I frankly like the Michael Tapes target+ruler product better, because you can directly see on the image the amount and direction of any mistuning. Multiply that by the several FLs you should test a zoom at, and you're talking a lot of time for not a reassuring result.Īs a consequence, one needs to resort to direct observation of the images to select an AFFT value that meet's ones needs, and this is where Reikan's method doesn't provide enough information to do so. Add to that a pass using Liveview as a control (it's always the most accurate focusing method). I've had to do multiple focusing passes (5-10) at each AFFT value to give the program enough data to work from. With Nikon it's mostly manual and a pain. The other thing I've noticed is that with a lot of lenses, notably the slower zooms, the tuning curve derived from the testing is quite flat and the software has difficulty determining a single optimal AFFT value. If you have a Canon product it's a much more compelling system because the process is fully automated.

I have and have used their software for AFFT on my Nikon.

They've just released the new version of their software after a long development period, so it's still in the 'early adopter' sales phase. Calibrate most Canon and Nikon cameras and lenses with FoCal Pro Lens Calibration from Reikan. In addition to the software license, a 150mm standard hard. Reikan has announced the release of version 2.0 of their FoCal focus tuning app. The occasionally put their software on sale the last special was for their 'hard targets'. Free Upgrade FoCal 2.0 is a free upgrade for all FoCal 1 license holders. Are there any discount codes for Reikan's Focal software? There used to be one( mbp45) but it no longer works.
