I do a lot of hiking.And I can step out of my house and within minutes reach a beautiful forest where I walk for exercise every day.I see many photography subjects such as parrots，snakes，hares，big trees and flowers.There are so many different flowers around my place that once I decided to see how many types I could count in a onehourlong walk，and I counted over 100.
Needless to say，as a keen amateur photographer，I always take a camera with me.I have three favorites: a Pentax Optio RZ10，a Sony Alpha 390 and a Panasonic Lumix FZ100.I mostly take the Pentax pocket camera with me.This Pentax pocket camera takes images as good as those from much more expensive Single Lens(镜头)Reflex cameras.It allows you to get to just 1 cm from the subject，and these images are of astonishing clarity(清楚)．I can stick the camera right into a flower.And the photo shows fantastic details.
The Pentax is also good at taking landscapes.The color is natural and price again the details even of distant objects are great.Sometimes，even when I have one of my other cameras with me，I still just use the Pentax pocket camera.About half of all the images on my website were taken with the Pentax.
The Pentax takes quality images in poor light and the zoom works well.You have to work hard to get a blurry(模糊的)shot.This is an especially good feature at parties and gatherings.You get fantastic photos of people.You don't have to wait for them to keep still.
Keep this camera in your pocket or in the car.It takes up little room；it's light and you'll never regret it!
