Lenses / Re: 400 f/2.8L IS I vs. 400 f/2.8L IS II
« on: Today at 02:41:05 PM »
I had the version I of the lens second hand for a year, sold it and recently got a hold of version II through a mentorship programme. In terms of IQ and sharpness, difficult to find major differences between the two, AF is fast on both except it had a tendency to keep searching more on the version I (in my case only maybe?), but what I found to be a blessing is the obvious and welcome decrease in weight. I literally got severe back pain carrying the version I, not telling the version II is a featherweight but oh so easier on the shoulders.
