You, along with thousands of others, have discovered the Achilles heal of the small digital cameras.
Two major problems:
Small camera dictates small battery.
Small battery dictates small flash.
The average coverage of small digital cameras is about 12 feet (at best).
You need to use high ISO settings indoors.
Small camera dictates small CCD sensor.
Small CCD sensor dictates excessive noise at anything over ISO200.
The DSLR camera has:
A large battery.
A built-in flash that can cover almost 40 feet.
An external flash that can cover over 100 feet.
A large CCD or CMOS sensor
ISO settings up to 3200 with low noise.
You need to rethink your requirements.
Perhaps something like a DSLR camera with a bright lens
and some photographic training for your people.
I have been asked to purchase a compact camera for our office. Many people will be using it, so it has to be easy for the 'non-photographer' to use. They want great images that can be used in powerpoint shows, etc, but don't want anything larger than a compact. I picked up a Canon SD850IS this weekend and am trying it out. The outdoor pic's are good, but the flash indoors was disappointing. (I shoot with Nikon D70, so maybe I won't find a compact camera that I'm not disappointed with...) This camera will be used overseas (so the battery life and recharge capabilities are important), in the office and in churches (thus the importance of good flash photography) and by many different people. Is there a better camera for this situation?
