Hello Bob. Found your video, very relevant for myself as I've also recently bought the17-40mm lens and agree with your opinion, what a lovely lens. Use mine on an R6 giving me IS which is an added bonus. Really enjoyed your video, down to earth and informative review.
Thank you for your review. I bought this lens, it's on its way, and I'm going to put it on a Sony a7r2 with its 42mp sensor, do you think this lens will have good enough optical resolution for nice printable photos?
