Size and weight
The first consideration prior to buying a digital camera is its weight and size. Can it be easily carried? Do your shoulders feel tired after an hour? Size and weight is more important than you'd think, if you can't carry the camera with you, then most likely you can't take any picture. Digital cameras come in different sizes, but they can be categorized into 3 groups, which are compact digital cameras, mirrorless cameras and DSLRs. In order to have the maximum portability while travelling, a compact digital camera will be the perfect companion as it hardly occupies any room in a bag, or pocket. Most models like Panasonic FT10 and Canon S95 are the powerful point-and-shoot cameras that you can slip into your shirt pocket, and you can even strap on your belt.
Zoom lens length
Digital cameras with zoom lens length less than 20X are often small sized and portable. It is also important that the zoom range should be at least 28mm wide so that everything stays in focus and you can get superb, sharp and crisp results whenever.
Ability to capture movies
The next feature that's found essential is the capability of recording movies. Most cameras can shoot some sort of videos, while those offer high definition (HD) movie recording function are becoming dominant in recent years. Cameras including HD movie recording capability are Canon SX30, Canon IXUS 220, Canon Powershot S95.
GPS geo-tagging
Geo-tagging inserts map location into the image files for where they were taken, and it offers a new twist on digital photography. By adding map coordinates into pictures, users can be able to search in photo archives on their computers based on the places they took their photos, not just the time. As geotag allows photographers to figure out where a particular photo was taken, it is easy to identify something like a Westminster Abbey after your memory of your trip to Europe three years ago has receded into blur. Today, Panasonic Lumix DMC-TZ20/ZS10, DMC-FT3/TS3, Canon SX230 feature a built-in GPS (Global Positioning System) function for users to record the location and direction of every shot they take.
