Yesterday I go to have some shoot with my 2 of my buddies on Marrina Barrage. After that, we go to Marina Sq to have dinner, which we take a look each others result...
Looking at one of my friend's result, I found quite interesting that all his landscape is shoots using f2.8 (he used a 5D and 16-35 f2.8 L). When I asks why he using f2.8, not step down to let say f8 to achieve deep focus, he even more surprise. From his reason, since his lens is a high quality one, he no need to step down like any one of those cheapo lenses. Even he reasoning, step down the aperture only wasted his lens' f2.8 availability. The other friend also try to reasoning with him and try to explain about deep focus, but seems he stands firm with his reason that f2.8 able to produce good landscape pics.
What do you guys thinking?
Normally I always step down to min f8-f10 when trying to achieve deep focus, and I believe this is also applicable to any L lenses (I don't have any)
