Indeed!
And its a nuisance; I need a lens of this general size and specifications, and there isn't going to be an alternative for a long time.
And it may not be easy: it could be that the extra diameter and weight of the Canon F4 is what you need.
I remember in the early days of digital Olympus used to go on about the importance of telecentricity in lens design for 4/3 cameras because of the requirements of digital. Maybe that's right, and for all that mirrorless cameras have advantages, the flange distance is not really one of them (except for versatility) as the best designs will still be tele centric.
One question: i wonder if I mightn't get better results on 36MP by shooting at 50mm and cropping rather than shooting at 70mm. Anyone care to crunch the numbers?
