I would have been fine with v2 had the price not seemingly doubled at release(I understand sales, vs release prices and MSRP, but that is what essentially happened in the short term(1 year at least.) With the price hike from v1 to v2 they should have made it IS, put the opening price at $2499, and if they had wanted to released the current v2 at $2249, or less.
They easily could have made the 24-70 2.8 II an IS lens to begin with, which we all wanted and expected,
many wanted and expected something with prime-like performance on a FF at 24mm and amazing f/2.8 center across the range in a reasonably small (smaller and lighter than before) package. And we got that.
I just don't like the idea of another new lens release with an insane price, especially when the concept of having IS in the this lens had been talked about for a while.
I'm all for paying top dollar for something if it gives me exactly what I want, but otherwise, i'd rather just hold out for the best, considering the price of v2 wasn't low either.
It's like the new iPhone here in China(where I live). They made the 5c for $730 bucks, and the 5s for $860. If i'm going to drop 700 dollars on a new phone, I don't want to wish I had the metal body, or better processor, etc(or IS), i'd rather just pay $100 dollars more and have the best. Likewise, if i'm going to pay $2300 for a lens, I'd like to be fairly sure there isn't an upgraded version coming the next year.
