The current buyer-facing maximum is Up to 2GB (CompactFlash Type I, FAT16); 256-512MB recommended for reliable use on this early model; for older or unusual formats, stay within that limit and avoid oversized cards.

Is the Nikon COOLPIX 3100 worth buying used?
It can be worth buying if you want a 3.2 MP effective Nikon digital camera from 2003 with 1/2.7-inch CCD. Check power, lens movement, screen condition, and storage access before paying.

How do you transfer photos from the Nikon COOLPIX 3100?

Nikon COOLPIX 3100 is worth judging as its own Nikon body, not just as a generic old compact. Start with condition, the exact battery/card setup, and whether its look fits what you want to shoot.
What owners like
Nikon COOLPIX 3100 works best when you want simple snapshots, direct flash, and the relaxed character people look for in older digital compacts rather than a technically perfect modern camera; its 1/2.5-inch CCD and 38-116mm equivalent, 3x optical zoom are the main character of the look.
Common complaints
Check the lens movement, flash, screen, buttons, and card door calmly before relying on it; older compact bodies can need a little patience without being a bad buy.
What to compare
Compare it with Nikon COOLPIX 2100, Nikon COOLPIX 2000, Nikon Coolpix SQ, Nikon COOLPIX S30 to decide whether you want this exact body, a cheaper nearby compact, or a slightly more capable alternative.
