Hi all, some great shots as of late. Work has been very mean in terms of hours, so I have been absent for quite some time.
I am now looking to replace the EF-S 17-85 with possibly the EF 24-105 F/4L as my new walk around lens.
Thoughts?
(Another lens I've got penciled in for further acquisition is the EF 35mm f/1.4L to replace my 50mm F/1.8)
I will have a hole at the wide-angle end of the range, but I'm thinking I may plug that at some point with the EF-S 10-22mm.
The 24-105 and the 24-70 are both nice, high decent quality (they are not primes) zoom walk arounds, but may be more suited for full frame cameras, as 24mm on a crop is not that wide. If 24mm is going to be wide enough, these should be your top contenders, otherwise you might also want to look at the EF-S 17-55 f/2.8. It is not an "L", but it is a pretty slick little lens that a lot of people are very happy with on a crop camera. It has very good build quality, and the optics are very nice.
The EF 35mm f/1.4L is probably the finest mid-wide in the Canon line up (although I haven't used the Mk II version of the EF 24mm f/1.4, it is supposed to be quite something as well). It is a really fun focal length, and takes superb images. You can't go wrong with that lens.
As for my lenses (I have a 5D), I have the 50 f/1.4, 85 f/1.8, 135 f/2, and the 24-70 f/2.8. Of them, the 50 is usually the one on the camera, the 135 is my favorite (although it is a bit long for indoor work), the 24-70 is used when I don't know what to expect when I'm taking the camera somewhere, and although the 85 is a nice focal length, I don't find I use it that much. I think most of it has to do with the fact that it doesn't focus very close, and right now with a 1 year old running around, I need a bit more flexibility in the focus range than that lens offers.
The 24-70 is a nice lens, it is great for a zoom, but it is a bit soft on the wide end, and after a while of using primes, even the non "L"s, you get a little spoiled by both the image quality, and the size and speed. I have been thinking about selling it and replacing it with a 35mm f/1.4 and if I want to really test my marriage either the 17mm or 24mm new tilt shifts, as most of my work at this focal length is architectural type shots for work.
Your best bet would probably go and rent the lenses you are interested in for a while and see how they actually fit in to your shooting style.
--EDIT--
I think I misread this part originally:
Other Canon users, do you have a place you have listed your lenses?
Probably one of the better places to sell is
