With the beginning of Spring Migration it is time to consider investing in new binoculars. This is a proposition that can present itself in daunting ways. Careful consideration needs to be made whether a new birder or one who has spent some time in the field and acquired some expertise. The optics field is quite large and the number of products is considerable. How does one choose a binocular? Here are my suggestions.

First, determine just how and under what circumstances you will be using your new binoculars. If you are going to be walking then full size binoculars are certainly worth your consideration. However, if you are a backpacker or will be doing your birding on a bicycle, then you may wish to consider mid size or even compact binoculars. If you bird by sitting in a favorite spot, then larger binoculars could be your choice. Size matters when one considers the mode of birding. Size is dictated by the objective lens. Generally, if the objective lens is 50 mm then it is considered to be a large binocular; if it is 42 mm, it is full size; if it is 32 mm, it is a mid size. Finally, compacts have objective lenses 25 mm or less.
