What software can show my most frequently used focal length?

Question

Many people recommend a focal length of 35mm, 50mm, and sometimes even 85mm and upwards for those interested in purchasing a prime lens. I, however, would like to figure out what focal length(s) I use most often, and then purchase a prime with that approximate focal length.

Is there a piece of software that will analyze thousands of photos and then tell me how many times I used a certain focal length?

Answer

Someone referred me once to Exposure Plot. This is a free Windows utility which is very simple. It shows you graphs of different parameters, one of them being focal-length.

If you already use image management application like Lightroom or Bibble Pro, then you can also usually see that data in the filter interface.

For Lightroom for example, you need to activate the filter bar (/), select Metadata and change one of the columns to show Focal-Length. You'll get to see all the focal-lengths used and the number of photos taken at each focal-length. What's neat is that you can combine things like rating and focal-length, to find out which focal-length is used in your best images.
