Here's an interesting (which way should I go).
I'm almost saved up to get a 35L - always wanted it, but I find myself wondering if I should consider a 5D as a second body.
I have 3 outstanding lenses for my 40D:
24-105L - my walk-around
and a 580EX II
The 35L and 10-22mm would fill in a critical space for me with my (young) children - Non-flash low-light capability - and also a fabulous wide-angle for crop. The 85mm f/1.8 is great, but definitely long indoors on my crop....
Here's the dilemma:
Getting a 5D body almost "doubles" my lenses in a way:
24-105L is wide and on a 5D format is simply "wow". I still have the 580EX II, so lack of built-in flash is no big deal.
85mm f/1.8 is more usable inside, and what a portrait lens on a 5D
70-200mm, although great on a 5D, still has 1.6x the reach on my 40D, and as far as speed, fps, etc., is a great match on the 40D
35L - well, it's my "dream" lens. On my 40D, it would be plenty wide enough for me (I've set my 24-105L to 35mm and walked around with it indoors to get a feel) and at f/1.4, wow. It would spend significant time on my 40D
10-22mm - 16mm FOV equivalent, and I'd have a blast with this angle. I have done a fair amount of stitching for landscapes when needed, though.
Lenses-wise, there's other options, I know. I've discounted the Sigma 30mm, especially since eventually I will pick up a full-frame, so I'm going to stay with non EF-S, with the only exception being 10-22mm (since there's no EF equivalent)
I'm not really interested in selling my 40D either. It has features that I know the 5D doesn't, so I'd be a two-body solution.
My budget is limited to $1,700, with an absolute cap at $2,000.
Anyone in similar circumstances?
