I'm weighing options in a new camera. I've been using a Canon 400D (Xti) for years, but there have been so many advances that I think it's worth upgrading. A 550D (T3i) runs around $700. The 5D MkII is around $2500. I wouldn't pay the extra $ for a 70D compared to a 550D - there aren't any functions that I need on a 70D that aren't available on the 550D (I shoot almost exclusively in manual mode, occasionally in Av). If I go with a small sensor camera, I would just go with that 550.
The ?'s I have are about the IQ difference between the 5D mkII and the 550D - 21mp on a 1x1.5" sensor vs. 18mp on a 22.3x14.9mm size sensor. I'm unsatisfied with the noise levels on my 400D. Most of my stock photography is done with strobe lights, but even with good exposures and ISO 100, there is a bit of noise in the shadows. I would also enjoy a larger file size and the ability to shoot outdoors with a higher ISO. I don't feel like I can shoot any stock on a higher ISO than 100 with my current camera.
Opinions on the IQ on the 5D vs. 550D (or cameras with same sensors) as related to microstock? Would the 550D be able to produce good quality files on any ISO's higher than 100 without having to use noise-reducing editing software? More editing means more time, which means less money
/ What is the highest ISO you've been able to use without getting problematic noise (without post processing or using multiple exposure techniques) on cameras with these two sized sensors?
Either camera will be a significant improvement over my current 400D, according to tests I've seen on review sites. But I wanted to get your views based on real-world experiences shooting stock.
So my main questions are how much quality improvement will I see with a 5D over a 550D, and how much faster of an ISO can I shoot with on the two cameras? Of course I would have to change a few lenses if I move up to the larger sensor size, but that isn't a real big concern for me.
If I'm lucky, a 5D mkIII will show up before I make a purchase - I'll probably be making a purchase in 2-4 months.
thanks in advance for your advice!!!
