As photography is my full-time occupation, I own a fair number of cameras. They tend to differ in brand, features and weight but those days most of my cameras are small mainly because of my frequent journeys by commercial plane. Airlines tend to enforce strictly carry-on rules nowadays and a large and heavy system is of no use to me when working overseas. People who want a carry-everywhere camera share the same desire for small cameras even if for different reasons. But it is not always obvious from an article in a paper or a review on the web to know how small a small camera truly is. Of course, you can easily get dimensions of a camera but what you really need sometimes is how small a camera that you lust for is compared to the camera you have or compared to another one you may consider buying. Well, fortunately there is a very good site for you to visualize size of a camera compared to another. There maybe several of them but I find that this one here is really the best. It is very user friendly and is updated regularly with new cameras. Most cameras can be viewed next to each other from different sides and you can see the dimensions by clicking on the product. Most products are classified by their full model name and alphabetically within a brand . However, latest additions are not always ranked alphabetically within their own brand so scroll-down the full list before thinking the model you are looking for is not here. You can see what a page may look like. You can move the products within the page by clicking on the small arrows in the little black strip with the camera name in it. You can remove one camera by clicking on the yellow arrow in the same black strip
For cameras with interchangeable lenses, you have a scroll-down list to attach the lens. A little trick : if comparing two or more cameras side by side is not enough you can click and drag one on top of the other to see both superimposed for a few seconds.
When choosing a camera , it is always better to hold the camera in your own hands to see how it feels but this website is certainly a nice tool.
Happy Pictures !
