I have a chance to get a like new 24 1.4 II for a good price ( $1200 ). How much better is this lens then a 17-40 or 28 1.8 or 24-70 ( at 24? ) I figured it would be a nice wide for my 5D and act like a 35 for my 60D. I don't shoot a whole lot of wide (but more interested lately ) or really do large prints but it seems like a pretty amazing lens but I am not so sure 1.4 is really as necessary on the wide end.
I can also get a 16-35 for around the same price but I am leaning toward the 24 for the filter size and really it just seems like more fun but I wonder if I am just gear lusting as I am pretty happy with my current setup. Just seems like it's worth considering.
Any advice is appreciated.
