When thinking about purchasing a camera for a child, there's a few options to consider. How old are they? How responsible are they with the handling of objects (are they particularly clumsy, gentle, respectful)? What's their attention span like? And how interested in photography or creative outlets are they? There is of course, also budget to consider- how much do you want to spend on a camera that they may outgrow, not use much, or break?

Refurbished digital point-and-shoot, under $60. Pictured: Nikon L22.
Both used and refurbished cameras are great options when you want better quality for a good price. This could be a point and shoot that you still have if you decide to upgrade, and then you can pass along that camera to one of the children, or a used or refurbished camera.

The digital point and shoots are better for a 12 and younger crowd, while the digital SLRs are great options for teenagers. And if you have a child that is really interested in getting into photography, then an older 35mm manual film camera is also a great option. These cameras allow much more growth, exploration, and learning for the older children then a point and shoot will. For a list of great 35mm manual cameras (and why these are great starter cameras), click here.

Underwater or weatherproof cameras are great options for younger children who may be rougher and/or prone to throwing things in water (like say, the toilet).

Other good options for kid-friendly cameras include: kid-specific cameras (better for little ones under 6 years of age), Lomography cameras, and plastic novelty cameras.
