Hello all!
I recently started to try to callibrate my lenses but I have to admit that is not so easy as advertised!
I am working with the Spyder Lenscall by Datacolor. I found that callibrating my 300f/4 was not so difficult but it is not as easy with the 600f/4. I took several pictures, all at the max wide aperture (f/4), then I took notes on what +/- adjustment I was setting on the camera, then I downloaded the images and open them in LR, I started to compare between pictures to find the ''sweet spot'' but I am not able to find huge differences between pictures, am I missing something? what would be the ideal distance to be set with the 600f/4, yes I know the minimum focusing distance is 5.5mts but what would be the right distance so that I can have enough dept of field to be able to judge any meaninful difference?
Thanks a lot for your help! :S3:
