Lens Buying Guide
Compared to a standard lens, wide angles have a better depth of field and clarity. 24mm and 28mm are the most common focal lengths. Wide Angle Lenses » Telephoto Essentially the exact opposite of wide angle lenses, telephoto lenses bring far off objects and subjects into close view. … Return Doc

Casio TRYX Review – A Review Of The Casio TRYX EX-TR100
One disadvantage is that the LED can cause some small glare spots on objects The downside to the LED is that it doesn't project its light as far as a traditional flash unit will, meaning you have to be pretty close to your subjects to record a usable photo.
