"Once in a while, when you are ready to resign things to being just the way they are and give up, the planets align, the clouds part, and the gods smile down, making everything right again. Well, perhaps I’m exaggerating a bit. However, my initial testing of the new firmware Version 1.01 for the Canon mount Sigma 120-300 f2.8 “Sports” lens is complete and things are looking good.
To briefly recap, my issue with the lens and original Version 1.00 firmware was basically two-fold. First, despite all sixteen adjustable focus points available in the Sigma Optimization Pro software being perfectly calibrated using the USB dock, the lens would badly front-focus in between the 200mm and 300mm settings. Second, the lens required completely different Optimization Pro focus parameter settings for the 1D Mark III and 1D Mark IV compared to Canon’s other bodies like the 7D, 5D Mark II and 50D. This meant my lens was either “set up” to work with my 1D bodies, or my other bodies, but never ALL my camera bodies at once. I began my testing with a very methodical approach. I needed to find out first if the new firmware fixed the issue of the different parameter requirements for the different bodies. I also wanted to get a baseline to see how different my new Optimization Pro setting would be from my old ones, and I wanted to do it for all my different camera models."
