7D is designed for sport, nature lives shooting. It's something similar to what Canon 1D is suitable for, with 1/3 of 1D sales price. The good things of a multiplier DSLR camera? You don't have to be concerned over the lense's quality, unlike many full frame cameras, such as 1DS ( I-III )and 5D(I&II ). 7D is likely to pull out the best part of any applied lense regard the sensor size. Nevertheless, it also needs superwide angle zoom lense, such as EF-S 10-22, for landscape shooting.
The good things for full frame DSLR camera ? The depth of field and the wide angle effects are most common factors. The full frame DSLR camera, such as 5D mark II, is very good for landscape and portrait shooting. But, you'll require to have some good lenses so that the qualtiy of camera can show the differences. Lense's vignet and soft edges are some common to find for a full frame DSLR camera. So, there's no absolute answer whether to go for a full frame or multiplier DSLR camera. Basically, it's the budget and type of shooting. Choose well and good luck
Okay, I'm feeling a bit flummoxed at my choices. I'm looking to upgrade to a dSLR early in the new year. I've been reading a lot on the 7D, and it's getting great reviews. However, from what I've read, it doesn't appear it's full frame. A pro photographer friend of mine has suggested I buy a used 5D MkII because it's full frame and she thinks I'll be much more satisfied with the images I get. The basic problem there is price. New is of course hugely expensive and used isn't available with the company I was planning to buy from, so no interest free purchase. And, from what I've read and struggled to understand, it sounds like I'd have to be a lot more selective about the lenses I buy with the 5D, because it shows up flaws that much better? Which means a higher price again.
I'm mostly interested in macro shooting, landscapes, and portraits. I do find wide angle shooting interesting and I'd like to do some of that as well, which I understand is much better on a full frame camera.
Is there anyone out there who has used both models? Is there anyone who's had a similar conundrum and can offer some advice? Anything would be better than the confusion running around in my head. Thanks very much.
