This lens seems to have an option for IS or non-IS... and the price difference of 750 dollars.
I can go without IS since I mostly always just use a tripod, but I also noticed the differences on this lens-comparison site, which to me look very noticable, with the IS version being much sharper IMO:
My question is... does anyone here think that included in the 750 extra dollars, some better optics are used, aside from the IS features? Perhaps this site didn't use the exact same testing parameters? I am not sure.
Thanks for reading.
