worth the effort Great upgrade for any Mac Pro 4,1 or 5,1 machine
in older machines like mine 2009 MacPro 4,1 it is a bit tricky i was able to get it working with just a few tweaks the 2010-2012 5,1 machines should be much easier since they incorporate a proper CPU holder.
worth the effort i estimate i will get another 5 years or more out of the machine which will make it nearly 17 years old. A testament to Apple's designers and the concept of using industral parts throughout their pro machines.

Great lens for Serious photographers
Great lens for those who are tired of letting the camera control your focus Image quality and Build beyond most lens manufactures today with the possible. exception of Leica. These Zeiss lens will last a lifetime
