Reasons to Upgrade
I'm growing frustrated with my current Canon 400D (XTi) camera body.
Below are issues I have with it, and how a new
Canon 7D
would address those problems. Are these issues worth the $1800 price tag
to upgrade (including several other accessories, less the resale cost of
the 400D)?
| Problem with 400D |
How 7D addresses the problem |
| Image quality in low light is lower than I'd like, and even at
my max ISO of 1600, I often can't get shake-free images.
|
7D allows up to ISO 12800, a 3-stop improvement over
the 400D. Despite the smaller photosites, image quality at ISO 1600
is also improved, with the 7D's 3200 on par with the 400D's 1600.
|
| Autofocus speed, especially at 300/5.6, is abysmal in anything but
brilliant sunlight. Manual focus through the dim viewfinder, despite
being off by a bit, is more likely to provide a usable image than AF
that hunts to the far end of the focus range.
|
7D has 19 AF points and a more advanced focus engine, compared
with the 400D's 9 AF points.
|
| When shooting with a tripod for portrait or other shots, especially
with manual lenses, it's difficult to know if I've focused correctly
using only the tiny viewfinder.
|
The 7D (and every other camera released by Canon after my 400D)
has LiveView with zooming, allowing you to see a 10x magnification of
the image on the LCD before taking the shot. Critical focusing of
stationary objects becomes trivial.
|
| The viewfinder on the Rebel series is very small and dim, which
makes it rather difficult to focus accurately with manual lenses.
The split image / microprism focusing screen that I added does help.
|
The 7D viewfinder is about 20% larger in each dimension than the
Rebel viewfinder. The drawback is that it's not designed to work with
replaceable focusing screens like the one in my Rebel. They are available
in the aftermarket, though. Oh, if only I could have a viewfinder like
the picture window in my Olympus OM-10 film camera!
|
| I sometimes will leave the SLR at home and take the point & shoot
camera because I know I'll want to shoot video at an event, even though
the P&S camera takes poor still photos.
|
The 7D can shoot 1080p high definition video. It eats memory cards
for breakfast, I'm sure.
|
| When shooting outside (or sometimes, in the bathroom), I'm worried
that a light mist or other mishap will ruin my 400D.
|
The 7D is fully weather sealed, making it impervious to anything
but submersion. To get the full benefit, the lenses must also be sealed,
of course, which means buying L glass.
|
| In continuous shooting mode, the 400D will only do 2.5 frames per
second. For any sort of action, that's not nearly fast enough. You're
better off trying to time the shutter for the decisive moment and hoping
you catch it right.
|
The 7D shoots 8 frames per second.
|
| When lighting with off-camera speedlite flashes, I have to forego
eTTL metering and power my flashes manually using cheap radio triggers,
which makes it hard to shoot in dynamic environments.
|
The 7D has a built-in IR-based, eTTL-capable flash trigger
that will work with my Canon 430EX flash (I think).
