yah, but considering u r likely, i guess, to be trying to squeeze in the foreground white rock and u will need to have a bit of sky on top of the head, u won't be able to get a square crop unless you move back or widened the FOV.
is that the widest of that lens? if it is 10-22mm, i thought u can go wider though.
for a while, i shifted from zoom to prime. then when i get a series of prime, i realise there are times when my vantage is limited and the composition i can get can also be restricted (e.g. waterfall and to avoid the sky), then i wish i have my zoom. i've 80-200mm f/2.8 super heavy. have always wondered if i should get 180mm f/2 so much lighter. i always used a 10-20mm and a 50mm f/1.8. though i wish to have a 17-50mm f/2.8, i doubt it will replace the other two and hence become a white elephant. probably will stick to similar setup and adapt accordingly to the places i go, kiv look for fast prime tele.
