I have an update on this post.

When working in close you should always set your f-stop as tight as you can. The f-stop is the amount that the iris of the lens is open and is expressed as a ratio of the lens focal length over the current diameter of the iris setting. For instance, if the lens had a 100mm focal length and the current iris opening was 10mm the f-stop is f10 (100/10). 100mm divided by 17.857mm would be f5.6. The larger the f-stop number the smaller the iris opening and the greater the depth of field you will have in your picture.

I am now working with a new/old camera that I bought on eBAY for $75. It is a Kodak EasyShare P850 that went out of production several years ago. Many people seem to think that Kodak made a big mistake when they stopped making it. It is light and easy to handle and has image stabilization which is a great help. We also found close-up lens set for $18 and that really helps working in close. This camera is a good idea if you are looking.
