Reikan FoCal Pro Lens Calibration 500mm lens

You can find my 500 F4 Sport images here and judge image quality yourself (my album also has images taken with my Sigma 150-600 C though, so please look at the tags below the images FYI). I am a relatively new owner, but I have tested the lens extensively. I'd also be interested to know how you rate the performance of this lens? I will however try your suggestion of just calibrating the lens plus the TC with the camera after resetting the dock calibrations to zero. I did make some using the Sigma Dock with the TC attached which seems to have made a slight difference. The lens BARE is sharp so I haven't made any adjustments to it.

Many thanks for the reply Manos and for the clarification re the best way to calibrate the lens. This way you don't have to fiddle with the lens itself via the dock, IF of course you get good results with the lens bare. The camera will see the LENS + TC as a NEW lens and will ONLY work under the calibrated figures, when you will be using the lens with the TC and not when you will be using the lens bare. Instead attach the TC to the lens and then on your D500 and then use the in-camera AF tuning to calibrate the lens WITH THE TC ON. If the lens BARE is sharp, then DON'T use the dock to calibrate it.

The lens can be brilliant but sometimes disappointing certainly compared to my no-nonsense Nikkor 200-500 f5.6 so much so that I'm thinking of trading the Sigma in for a second-hand Nikon 500 f4.Īny help & comments would be most welcome. My question is how to correlate AF fine tuning the Nikon camera with the Sigma USB dock to get best results? Frankly neither seem to work with the teleconverter attached and the results I get with it are extremely disappointing whilst the images without it are sharp. I use it in conjunction with a Nikon D500 & a Sigma 1.4 extender/converter. Hi - sorry to reopen this discussion but I am now on the second Sigma 500 f4 as the first had a faulty collar locking screw and was eventually replaced by WEX.
