Ok...you got me there....I bow down!
No need for that. I just read too many threads where someone rejects the lens they need for the lens they might eventually need. But it just doesnt make any sense to limit yourself for a couple of years because you want to go full frame someday. Given that I have actually made money on two lenses that I sold after a couple of years use, its a pretty safe investment.
Now back to the greatness of this lens.
