i think i have almost masterd my 450d, very use'r friendly camera, now im thinking of moving up ,which would be the next step up,,,7d maybe,any advice ?

I've been mulling over a similar upgrade myself. Although I'm really happy with the quality of the 450, so I'm wondering if I should invest in some lenses first. Are you finding any particular limitations in your 450 that need addressing?

I have a 450D too and I would like to upgrade too.

What I miss more:

bigger sensor (I can crop more the subject)

more ISO and less noise (macro photo sharp nd more DOF)

HD movie (holiday and baby movies)

focus regulation (to fix back focusing issues with lens)

I'm wondering if the price difference between the 60d and 7d justify the added expense.

i have the box lens that came with the camera18-55 ,then i brought 55-250 canon lens and a 18-135 so i think i have the lenses coverd, i dont want a camera for making movies, ive seen photo's that have been taken with 5d and 7d camera's they seem to be so much quality photo.s,, maybe i have not masterd the 450d, or exspect to much from it,

The 7D, 60D and 550D all appear to use the same sensor,

18Mp with 5.4Mp/cm²

Your old 450D weighs in at 524g

The 550D is 530g

The 60D is 775g

and the 7D is 820g, without the battery.

All the other figures are with battery.

For me a camera must sit comfortably in my hands

and going from 550D - 60D - 7D is a step up in size each time.

......(macro photo sharp nd more DOF)

Is a new body going to help DOF?

focus regulation (to fix back focusing issues with lens)

Do any of these cameras offer that facility for the user?

Surely it is a workshop job

Anyway, that is my 2 pennth.

I use a 40D, and do not feel a need to upgrade........ yet
