I've been a big advocate of the Canon 17-40mm f/4 L for a number of years and for the number of times the wide angle has dug me out of a hole, the f/4 aperture has put me into one. For all the events and projects I have worked on, there always seems to be a common theme...low light. And although the 6D performs well at high ISO, I am reluctant to go above ISO 1000 unless I really have to to get the shutter speeds I need to freeze action sports. I also want to make a shift to using prime lenses exclusively up to 70mm, as the fantastic 70-200mm will never be made redundant!
The Sigma 24mm f/1.4 comes in at almost half the retail price of the Canon equivalent, and have yet to find a review that states it performs half as well as the Canon. In fact many say it out performs the Canon 24mm f/1.4. Big words...only one way to find out I guess.
I used this lens for a recent shoot for The North Face. This shoot posed a couple potential issue; low light, and a need to freeze runners with only a speedlight at my disposal. I had to keep my fstop backpack light as I was running the 10km course with the runners! The lens performed amazingly and gave my images the look I have been after for a long time. The decision to trade in my 17-40mm has paid off already!
Here are random shoots from a golden hour walk around the block using my new shiny lens!
