Over the winter, sports shooting slowed down to almost nothing, so I picked up some portraiture and landscape, and now shooting sports is just not as appealing to me anymore.
I've found that my 70-200 f4L works well for headshots, but is a bit long for 3/4's and full body, especially in my home studio where distance between me and the subject is limited.
I love the perspective that the kit lens gives wide open at 18mm, but I feel the performance is way behind what I get from the f4L. That's why was looking to trade/sell my 70-200 and grab a 17-40 f4L to replace it.
From what I've read, it would be a great landscape lens, but I'm curious how well it would work for headshots. At 64mm on the long end on the 1.6x sensor, it seems a little short, and I could possibly just use my nifty fifty for headshots and pick up a super-wide (tokina 11-16 or similar) that isn't canon L, although I <3 L glass.
Any suggestions on lenses to replace my 70-200 with? I'm fine with buying off brand lenses, but a constant aperture is a high priority, as well as a price under 600 (I don't mind buying used).
