5D III (toying with the 1D IV for build and speed but perhaps as a second body next year?)
16-35 II (traveling, street, some landscape, group or environmental portraits even)
70-200 2.8 IS II (everything...weddings, events, portrait, some closer wildlife)
135L (covers my portraits, some street stuff, events/stage stuff)
24 1.4L (not as good as the TS but it's more versatile. churches, markets, lowlight, astro)
100 Macro (L or not? IS can come in handy and its only a $240 difference, weather sealing is a selling point)
50 1.4 (better bokeh than the 1.8, which I'd keep as backup or lightweight setup)
MAYBE a 600-RT but that likely comes last.
Thanks in advance for all the help! If you want some degree of feel for what I shoot, visit www.rfaganphotography.com.
I would choose a 5DIII over a 1D4 any day. Higher rez, better iso ability....a quiet mode which is spookily quiet and a build quality which is very close to a 1D series. It's AF system is better than the 1D4 too. It's not like any previous 5D series cameras. If you are shooting weddings then a pair of 5DIII's are probably the most perfect fit from any brand....those cameras were designed to shoot weddings.
16-35IIL is probably the most versatile ultra wide currently available. Sure it could do with an improvement...but it's a great all round package and does what it says on the box very well.
You won't need a 70-200 f2.8 and a 135L...they are very close in range and application. Either sell your zoom and replace with a prime or stick with your current zoom.
I personally prefer the 35L over the 24IIL, but both are optical gems and great performers. If I was using a 16-35IIL, I would choose a 35L. But the best thing to do is rent them both and see which one floats your boat. Your making long term investments...so it's wise to make informed choices.
The 100L macro is sharper than any 100mm USM macro I've tried and the IS is great for handheld wide open shots. It has better contrast and colours too.
If I was buying a 35L, I wouldn't bother with the 50mm f1.4...they are very close together in range...just half a foot step closer. Optically, the 35L is in a different league...as well as build.
The 600RT is a great flash, but it's radio options need further units and triggers to have a working system. If this is an area you wish to explore later by adding further units, then it's the model to go for. If not, then a 580 would probably be a better fit for you and a bit cheaper too.
