I would like to see a photo...

Long ago, we chose the camera to use, and sometimes the lens, based in part on the end use of the photograph.

If we were shooting a full page magazine ad, chances were prety good, in 1960, that a 4x5 camera was being used.

I was shooting weddings during the transitions from 4x5 to 120 to 35mm, and there were lots of times, I'm sure, where the client would have been unhappy with a 35mm shot of, say, the whole wedding party.

TODAY, WITH DIGITAL... there are still editors and art directors with specifications from the past that eliminate some bottom of the line cameras from 3-4 years ago.

It would be harder to sell a 30x45 enlargement of a skyline showing a dozen buildings with lots of signs and cars in front that viewers try to look at carefully if that shot was taken with a T3 and a 75-300and it would be easier to sell with a T4i and the 18-55 lens at a medium zoom and moderate aperture, plus almost twice the pixels.

BUT I SUSPECT your question is about the difference between the T4i with the kit lens and a 5D-III or similar, with some $1500 L lens.

I can't think of any difference that matters.
