HI Ken, I agree with most of it, except that I think 77 is equally sharp wide opened. I remember testing my *ist (35mm) with this lens - I shot almost a roll of Reala at f/1.8 and they are all sharp, very crisp with distant subjects. Of course the sharpness would be more even stopped down, and definitely this is the best lens I have.
The only limitation is the slow AF, but it focuses manually almost like a real MF. I just need to buy that 31mm to satisfy my thirst of complete LTD lens, but the price keeps me away from getting it! Regards, Winston >>77mm is still in a good portrait range and very sharp. It does not have the sharpness of 85mm in wide open but I never minded. <<
