One last test of the new lens is how it works with the 1.4X Telextender. Today, I headed off to the Orlando Wetlands Park for a nice, relaxing walk and an opportunity to test that combination with some of the wildlife that lives in the park. Saw about a kazillion alligators and took some pics of them. But my main objective was the birds that are in such abundance in this great habitat. I managed to capture some very nice images of the usual suspects but also found a few species that I've never seen before.

Early in the walk, I spotted a Red-shouldered Hawk cruising overhead having just caught its dinner.



A short way farther up the trail, I spotted an Ibis unlike any that I have seen before. This is a Glossy Ibis and its wings and back are positively iridescent in the sunlight.



Around the next bend, I saw another Ibis that I had not seen before. This guy -- a White-faced Ibis -- was hanging out with several Black Bellied Whistling Ducks which are very rare here in Central Florida.



Next, a Little Blue Heron.



A lovely Sand Hill Crane who let me get very close.



And a Yellow-winged Black Bird.



And, finally, a Great Blue Heron preening in a tree at water's edge.



So, what's my conclusion about the lens and, specifically about the lens with a 1.4X Telextender? Fabulous! Would I love to be shooting wildlife with one of the "super telephotos" that is in Canon's lens lineup. No question. But I need to be able to justify my equipment based on whether it can pay for itself in my business. I don't sell nature and wildlife photos. And so for me, my lens needs to be able to shoot dog show ring candids and Herding Trials as well as shoot wildlife and create images that are acceptable. The Canon 70-200mm F4L IS, whether separately or combined with the 1.4 Telextender, fits the bill. How would it work with a 2X Telextender? I really don't know but, personally, I have some hesitation combining a relatively slow zoom lens with a 2X extender. Lots of glass. Maximum F-stop of F8. No autofocus with the 7D. Just doesn't make much sense for me.

Anyway, testing done and I'm delighted with the lens. It's sharp, versatile and it'll pay for itself in one Herding Trial. I'm a happy guy!
