Please forgive me for such a question. THis is my first time with such an ultra wide lens. I am shooting on a 5dmkII and received the lens (brand new) as an early Christmas gift a couple days ago. SO today I set up on the tripod and take some shots outdoors. I used a hyperfocal chart with lens set at manual focus. Now there are very few "hash marks" on this lens distance scale, but I should have been very close. I shot at both f/8 and f/16. I eagerly downloaded the shots and had nothing but mush on the screen. So I go back outside and set the lens to infinity and take a couple more shots and things are much sharper. I guess I am just confused. In the past I always used the hyperfocal chart when doing landscapes with my 50mm and up lenses. Is it just that the 16-35 is so wide that infinity is the best for broad landscapes? Even the very close foreground appears sharper with the lens set to infinity focus. Thanks for any advice in the matter.
