I currently have a 40D with a 17-55. I am looking at getting a 5D3 with the kit 24-105 lens. I am also knocking around the notion of getting the 24-70 II instead of the 24-105 in order to maintain 2.8 aperture.
I am a hobbyist who likes to do portraiture, the odd event, vacations and the like. I also have an 85/1.8, 135L and 70-200/4/IS.
I never go above ISO 800 (unless I really need to) on the 40D - what would be an equivalent ISO on a 5D3 or even a 5D2 for that matter? 3200?
The 17-55 is on the camera 95% of the time. Based on the better ISO performance of the 5D2 or 3, if I boosted the ISO up to make up for the loss of a stop on the lens, do you think they would balance each other out from a noise standpoint (DoF issues aside). In other words, if money was not an issue, as a general everyday lens, if you were me would you get the 24-105 or the 24-70 II?
Thanks in advance!
Get the 24-10 Kit, it is a really good match for the 5D series cameras. I almost bought a second one with my 5D MK III order. If it does not end up suiting you, you can sell it for over $800.
I've had 5 of the 40d's and loved every one of them. ISO 800 was pretty much my limit. Just now, i pulled some of my old ISO 1600 images into LR 4, and they really look good, so newer processing has changed things.
With the 5D MK II, I was limited at ISO 3200 originally, but with the better image editors, I can now use ISO 6400 in a pinch without too much noise. I expect to use ISO 12,800 or even 25,600 on the 5D MK III. Thats a really huge jump over my beloved 40D's.
Here is a theatre shot at ISO 6400 taken recently with my 5D MK II, I'm really enthused about the possibility of two more stops. I would have bought it for one more stop.
