What is the smallest digital camera? That is not a question that is easily answered. Digital cameras are getting smaller all the time, some of them to dimensions that would have seemed impossible 10 years ago. The next question would be "Are tiny digital cameras as useful as normal sized ones?" The answer to that is a yes. Cameras that are no longer than your bigger than your forefinger and can fit into the palm of your hand are as useful as regular sized cameras.
While smaller models of digital cameras are not very useful for professional-style photography they are just as useful for everyday pictures as their larger counterparts. It is standard in all digital cameras to include flash, focus, and zoom. The best part is that they are not as expensive as larger models either, but that is for good reason.
Many of the smallest digital cameras do not have a lot of built-in space to store pictures, and because they are so small, chances are you will have to purchase a Micro SD card. These are getting cheaper by the month it seems like, so this is not a huge problem. What is a problem is that many miniature digital cameras do not have a screen for you to view the pictures that you have taken. This has become a standard feature for any normal-sized models so it may be difficult to get used to. Not being able to check to see if a picture is just right can end in some bad photographs.
Several models also do not have the ability to record videos, which is another feature that has become standard in digital cameras. This is one factor that really convinces people not to purchase some of the smallest digital camera, but if you are not concerned with recording videos then it should be no big deterrent.
The truth is, these types of cameras are a bit of a novelty. They are very cute, and it is amazing that something so small can effectively take quality pictures. However, they tend to get lost easily and some of the cheaper ones on store shelves can break if dropped only one or two times. They are to be handled with care. Losing all of the pictures you've saved on a digital camera can be frustrating, if not extremely upsetting.
All in all, the smallest digital camera is certainly an affordable alternative to a standard, multifunctional model. They are great if you are looking for a camera to take on the go or to give to a loved one as a gift. They are handy gadgets, but if you are serious about taking pictures then it is better to look elsewhere.
