- Really heavy, but capable of wonderful quality
3• Lens

- How large should the maximum aperture be? Bigger apertures (smaller F number) means faster shutter speeds in low light situations.
- Can you increase the range of focal lengths?
- Are lenses interchangeable?
4• Viewfinder and LCD monitor
- Does the camera have an optical viewfinder? Does it work when you use attachments?
- Does the camera have a LCD monitor?
- How fast is the LCD monitor?

- How clear and high resolution is the CLD monitor. Is it clear enough to reliably judge the quality of the picture?
5• Built-in flash
- How powerful? What is the range of distances over which the flash works?
- Can the flash be used with other attachments, or do they get in the way?
- Can you use an external flash?
6• Storage media
- Which type: Compactflash, MemoryStick, SmartMedia
- How much storage space on the media that comes with the camera, how expensive is it to get more media?
- How easy is it to handle the media? Is it so small you are afraid you will lose it or break it? Is it bigger than you want to make space for in your camera bag?
- What accessories will you need to download the images from the media? Digital film reader? USB cable? Etc.
7• Exposure value choices. Most cameras have a range of sensitivity settings, usually expressed in ASA numbers (i.e., 100, 200, 400). The higher the number, the greater the sensitivity. The lower the number, the better the image quality.

- How good is the image quality at each setting. The Highest sensitivity settings have a tendency to be "grainier". Take a look a sample original photos in Photoshop.
8• Power
- How long will a battery charge last?
- Are the batteries a common type, or are they only only available from one source, and probably more expensive?
- Does the camera accept standard non-rechargable batteries, in case your charger dies while you are on vacation?
