I have had my Canon Digital Rebel for a year now and I just noticed that the
capacity of my flash card changes if I change the ISO setting. For example,
at ISO 100, the camera readout says I have room for 287 pictures (on my 1GB
flash card). At ISO 1600, the camera says I have ...

Hi..Im looking to decide between these 2 lenses for my Canon 400d....
EF 70-200mm f/4L USM
or EF 70-300mm f/4-5.6 IS USM
I'm looking at these particular lenses because I want a nice lens to take

optimum focus slightly ahead of the automatic
one.
Can this be compensated for by some

No one would argue that Canon dominates the professional photo
market.  In nearly every field.  Neither would anyone argue that their
cameras aren't at the top of the photo heap when it comes to quality.

Are the really fast lenses really practical for indoor shooting at
gatherings?
I am concerned about the narrow depth-of-field at wide openings, or is
that not really a problem if you don't get one more than about 30mm (ie

Guy walks into a downtown camera store and says, "I like to trade my

The status information in the viewfinder is very dim - so dim that I
often can't see important information, especially in bright sunlight.
In particular, I use a 28mm Pentax A lens with stop-down metering, so I
really need to see the exposure information in the bottom right.

I recently upgraded my flash to a 580 EX and I'm having a problem coming to

down to Nikon P5000 & Canon A640 (because I want the option of an optical
viewfinder). Any opinions on this.
