I have a dilemna. I will be getting ~1500 for my tax return this year. I was really hoping to get a FF camera, but the 1Dmkiii is looking better and better as of late. Which would you guys choose?
For some background, I do some paid events (on the cheap, still a student), but my real passion is documentary style work. I shoot mostly film but have a gripped T2i for a digital body. I know my way around this thing like the back of my hand, and let's just say it's all I really need. HOWEVER, I would like increased performance, and we all know that when you're being paid for a gig, appearances matter. Though I deliver the images with a consumer body, I don't want that marring my rep before I can get them to sign a contract. Before the flaming begins about using a t2i for paid work: I try to borrow a better body before a shoot, and always have a back-up, film being a tertiary back-up to a second digital body. As far as I'm concerned, I'm using the T2i to it's full potential and can handily work around its limiting factors.
So here is my break-down of pros/cons so far, cost not being one of them as they are very comparable in price in the used market:
5Dii pros:
FF - I really like having the 'real' 28mm FOV with my 28mm 1.8 on my EOS film camera. It's fantastic. I don't really need more detail or shallower DOF than a T2i delivers, however.
ISO performance - As far as I understand, the 5Dii has an edge here. Is this correct?
Megapixels - More usable pixels for larger prints
5Dii cons:
AF the same (or worse) than my T2i once you consider the spread
1Diii pros:
AF - I am really amped about having a pro autofocus system. With the T2i I just use center point.
Pro body - I like the feel of a nicely balanced camera. Weight is no issue for me.
Appearances - put clients at ease about the quality of my work
1Diii cons:
Lower res screen - Not a huge concern
Less usable MP - 10mp should be okay for me. It's acceptable, but on the low end
Older - More use, obviously
Crop factor - I wanted FF for my lens line-up.
My lenses: Sigma 10-20, Canon 28mm 1.8, Sigma 50mm 1.4 (coming very soon), Canon 70-200 f4 IS. Is this a good kit for APS-H/APS-C combo? I plan on keeping my T2i as a backup.
