Hi, I have a Canon G3 digital camera, which I've had for a number of years
although it hasn't seen much action. I was disappointed with the shutter
lag and due to this in three years it's taken under 700 shots. I recently
purchased a Sony Cybershot DSC P100 and the difference in speed is marked.

Is the improved shutter delay purely due to improvements in technology over
the last few years or could it have something to do with the speed of memory
card? In the Canon I was using a 12x Lexar card, my Sony has a Lexar Sony
Memory Stick Pro.

I was looking to have a bit more control over my photography than the Sony
offered and looked out my Canon again. Although I'm sure the picture
quality is better; despite the lower pixel count, I'm frustrated with the
shutter delay. Will I see a marked difference (or indeed any) by upgrading
my memory card to say a SanDisk Extreme III?

Your help is appreciated.

Kind regards

Kev

I doubt it. Writing to flash is slow such that data is buffered in RAM
while the various flash writes occur. More RAM buffering allows a faster
"motor drive" for digital cameras.

Shutter delay improvements are probably due to faster microprocessors
inside the camera.

The Gs are a great camera, but as you say they suffer from lag, even the
later G6s aren't so brilliant in that regard.

If you want speed and control have a look at a new or used digital SLR,
which is where I went from the G2 (lag), even the older SLRs are very
quick. New DSLRs are comparitively cheap nowadays [1] and there are some
great used buys too, just factor in a good lens on top because the glass
on the front of the G will beat the cheap kit lenses.

[1] The brand new Canon 400D with a lens will probably cost less than
the G3 did new, I've just priced one up for about £30 more than we paid
for a G2 on discontinued clearance.
