But what's the main differences between G5 & G10?
The two models were released five years apart, and it shows.
The G5 has a 5-megapixel sensor; the G10 is 14.7 megapixels.
The G5 has 4X optical zoom compared to the G10's 5X.
The G5's LCD display is 1.8", the G10's is 3" and much higher
definition.
The G5 goes up to ISO400 while the G10 goes up to ISO1600 - not
that this makes a difference since noise kicks in at ISO200
anyway.
The G5's highest shutter speed is 1/2000 sec compared to the
G10's 1/4000 - if you don't have enough light this isn't going to
help you any.
The G5 in fact has some adtantages over the G10:
- it shoots at a maximum of 2.5 fps - much faster than the G10's
0.7
- the maximum aperture is larger at f/2.0 compared to the G10's
f/2.8
- the G5's screen flips out, letting you take shots from odd
angles; the G10's screen is fixed
In any case it's a moot point since the G5 stopped production in
late 2004. You'd be lucky to get one in good condition these
days.
