... would the 28-70mm L be a better buy than the newer 24-70mm L?
I've been reading threads and online reviews, and aside from weather sealing and an extra 4mm, its a toss up regarding IQ between these two lenses.
I'm going to buy a 5D pretty soon and would love a 24/28-70 standard zoom, but the 24-70mm is considerably more expensive here in Japan (even used).
If anyone has experience with both, can you tell me if the 24-70mm is worth the extra money? I read that the 24-70mm has "more" copy variations.
Would Canon still service the 28-70?
I'm a serious hobbyist that likes to shoot candids, studio portraits, and just general photography fun.
