I bought the Lens something from spyder. Either my eyes are not good enough or....
I have that Issue, I can not see the fine differences once the setting gets close.
1) do you have to buy a new program for each body ( their website asks you to order for a specific body). My camera is a 5D II, but I have and am still borrowing a 1Ds III for the last three years. Hence would I need two payments and two programs for those. The questiens becomes even more pertinent if I finally Get the 1Dx.
Your purchase allows you to use FoCal on 5 different bodies. You can add or remove bodies a limited number of times, which is to prevent users from cheating, but you can have five at a time.
2) does the program do the callibration for you? (Of course you need to set it up and so forth) But will it set the appropriate values for you in the camera, or would you still have to go through with shooting many shots,to narrow the gap down as with the solution i have today?
The answer depends on the camera body. The 7D and 5D MK II are full automatic, but the 5D MK III and the 1D X cannot have full automatic calibration due to limitations in the Canon SDK. So far, a way to make the calibration fully automatic for those bodies has not been found. You have to follow on screen instructions and change the AFMA value manually between shots, otherwise, its automatic. This actually goes pretty quickly, since they have improved the ability of the software to find the right value with a minimum number of shots and AFMA settings.
