I was spoiled the other day while observing peregrine falcons (besides the fact that I was observing peregrine falcons!) – a fellow East Bay photographer, George Suennen, let me borrow his “more advanced” (aka more expensive) lens setup for a couple of shots (Canon EF 300mm f/2.8L IS II USM Telephoto Lens with a 2x teleconverter). I REALLY REALLY don’t want to like this piece of equipment, but … WOW. Very gracious of him to offer for me to use it, I’m not sure if I thank him or curse him for putting that thing in my hands!!
Right now I typically shoot with a different Canon 300mm lens – the Canon EF 70-300mm f/4-5.6 IS USM (but I DON’T have a 2x teleconverter attached – which brings the L-series lens setup to an equivalent of 600mm!). To understand the difference in lenses, a visual comparison is in order of course. Both images below are cropped close to 100% but no other post-processing has been applied (sharpening, contrast/brightness adjustment, etc). The same camera body was used. The difference between the lens setups is very evident.
Are the results worth 14x the amount of money more? I suppose that’s an individual choice. It’s certainly understandable why this lens is rated one of the best in the Canon lineup, and a standard for many sports and wildlife photographers. Until I make the jump, I’ll have to continue to get close to subjects without disturbing them to get clear shots … which is a large part of the fun – and helps to force me to really get the most out of my equipment and techniques.
