I own the models 1 and 3 of this line of cameras. The 6th iteration's lens began to accumulate dust almost immediately, making it nearly impossible to capture sunrises and sunsets. Versions 1 and 3 were used concurrently for 2 years without any issues; it's unfortunate that I paid $70,000 for this equipment. Perfect photography, enhanced stability, and autofocus. The 6th version's DD is also marginally worse than the 3rd version's; the shadows are not as pulled out and there are more overexposures. Only a greater zoom is a big improvement over an M3, and the price is 30 more.
