First of all, my gear:
Body: 5d mkiii
All purpose zoom: 24-105mm f/4L IS USM
Tele-zoom: 70-200mm f/2.8L IS mkii
Primes: 8mm Rokinon fisheye & 100mm f/2.8L IS Macro which I am selling and will replace with a 135mm f/2L which will then eventually be replace by an 85mm f/1.2L prime
Speedlite: 430ex mkii and I am in the market for a 90 ex to use as a hotshoe master for off camera triggering.
Now the circumstances I find myself in. I was looking for a backup for my mkiii just incase it decides to flip out one day and I'm stuck without a camera for a week or two (though I know CPS is good about giving you a temporary replacement.
Well... what I did was buy a 17-55mm and a 50D. I previously had a 60D and my lone issue with the 60D was the lack of AFMA. I know AFMA is less of a concern at f/4 and above, but as discussed above, I'm looking at f/2 and eventually f/1.2. And yes, I will more often than not use those lenses on the mkiii, but you never know.
Part of the reason I wanted the 17-55 is to get a sense of the focal length. On the 50D, the focal length is roughly 27-88. If I have the focal length, then I know I won't care for the 24-70 f/2.8L USM mkii. Also, the extra stop would be nice... but again... if I'm going to an indoor event... I can't imagine taking the 50D over the mkiii.
So am I going to use the lens? I'm almost leaning towards no. I have it up on Amazon, so if it sells the decision is out of my hands... Dang EF-s...
As long as you have ANY crop body (besides a 1D series) KEEP that 17-55. It's the perfect walk around on your 50D. I much preferred mine (when I still had my 40D) compared to my 17-40, 16-35, or 24-70 on crop use.=. It's just too good of a range to give up.
But he has a 5D3 and 24-105, which has a better range! Why would he walk around with less range? Don't get me wrong if all you have is a crop body I fully recommend the 17-55 as a walkaround. But now that I have my 24-105 I will use that as a walkaround lens. Am I missing something?
Because I don't think he's talking about selling the 50D and lens, just possibly the lens. The 5D bodies and 24-105 are a great walk around combo in most places. The 50D and 24-105 to me is not a great walk around combo when compared to the 17-55. Yes you get more reach which is useful, but I'd rather have more wide angle and that 2.8 IS as a bonus. But that's my personal experience, as I pretty much didn't like using the 24-105 on my 40D compared to when I used the 17-55 on the 40D. Shots in tight places with my family and/or friends turned out easier to use with the 17-55 on crop than 24-105. Yes there were a few times the extra reach of the 24-105 was nice to have on the crop, but not as often as having the wider end, again at least for me. I love the 24-105 range on my full frame bodies, works out much better than 24-105 on crop. There is nothing wrong with having the 17-55 as part of a backup lens on a crop body. I had that combo as a backup set myself for a long time, until I went dual full frame body. If he consider's selling just the lens, then I'd rather he sell the 50D as well, and get a used 5D classic. That would be a better backup, as he woudn't have to re-adjust for range in a pinch. But only if he's willing to sell both. Since I don't think he is, then I don't see why he should sell the lens.
