As other CSer have stated, a fair comparison need to be done, i.e. same lens, same setting, same subjects, etc. I never compare both, but from spec wise, IMHO, 7D and 450D doesn't different much. Maybe at pixel level yes.
Canon make classification and class of their body definitely with a reason,
not just because it has 3 digits and 1 digit only :bsmilie:
I've using 400D - 450D - 500D, 40D, 7D and between 3 digits, 40D and 7D it's different,
picture you take from 3 digits looks like a painting, it's just not real, 40D and 7D does better
Canon XXXD series is by no mean crap. My brother's 450D can take pictures with colour, contrast and sharpness comparable with my 1DM3. Of course these photos are taken with low ISO (< ISO 800).
I would think that camera body will affect the IQ when it comes to low light situation, high ISO capability. If you are shooting without flash almost all the time, like I do, then camera with larger sensor (or larger pixel size) will really benefit.
This is a joke, right ?
It is your brother has a better skill and you're no match for him (kidding) :bsmilie:
Well, if it is like u said 450D comparable with 1D Mark III,
let's say it's in bright light condition and low iso settings,
why do the pro using 1D body while they're doing their job if there is sufficient lights ?
It's cheaper for them to get 450D body rather than 1D Mark III body,
even if they break 8 units 450D on the job, the costs similar with 1 unit 1D series :bsmilie:
I dont think XXXXD or XXXD series are crap like you said, they still can produce stunning photos if you know how to work the settings to your advantage.
more impt is the one behind the cam, imagine you pass a 1DmkIV to a totally newbie? He will just put it to auto mode and snap it like a PnS...
Actually there is no AUTO mode in a 1D series body, right ?
Is it a new feature from 1D because a lot of people like to jump ahead to 1D ? :bsmilie:
