24-70mm is really heavy and huge and I do agree that its one of the best lens.
I also do prefer the lens because of its focal length but yet again its huge and heavy and I might just afraid not to carry it for shoot and ending up using my 50mm instead.
I wonder if there is anyone sold this trinity lens just because of its weight and I don't want to be one of them. :dunno:
my fave primes are 35mm and 85mm. now both 1.4 and for travels and walkabouts, i tend to use these more often. (consider the 35/2 paired with 85/1.8 if weight is really an issue. they are cheaper, lighter and very very good).
but i won't sell my 24-70 because i find it's still the most versatile for events (i don't shoot professionally - i meant for friends n family). depending on situation (lighting/ size of place etc), i couple 24-70 with either a f1.4 lens or 17-35/2.8.
yups, it's heavy cos a 28-105 or 24-120 will give better coverage with less mass. but when i browse the pics after that, i know the extra grams are worth it.
