Math and Magnification

Parked on the shoulder of the cutoff road under the Intracoastal Canal bridge, Bill Maroldo was working on a Great Blue Heron on his side and I had a nice Little Blue Heron perched on a post on mine. We had some sea fog so the light was nice and there were no crabbers to disturb the birds. Bill suggested I might like to use his 1.7x teleconverter instead of my 1.4x on my long lens.

You can already see where this is going, I bet.
