Thanks guys. As stated before, I try my best but have lots to learn. I'm so thrilled to hopefully have a few years ahead of me with such great gear. Boy capturing fast BIF is a major challenge with that 300 X2.
Dustin, I sent the 2 extenders, camera, and the 300 but didn't send the 24-70 F4 as I figured it was good compared to what I saw of the more highly rated version. They did test them out together and I'd like to believe tweaked some things but all I learned was the upgrade to the 300 firmware. BTW, it's shameful how some have knocked the WiFi, calling it a joke when it is exceedingly useful in the right hands. I'm in the process of constructing a treepod and hope to move back from my sensitive subjects and shoot remotely.
For security and to reduce the hassle I used Don's Photo return service and that was great except the Canon tech would not speak to me directly and there was some mis-translation of my concerns. Isn't that how it always goes!
Regardless, I will be happy and forget the fussing and hopefully get shots that are worth posting and warm the hearts of those that view them. I guess that's what it's all about, right? I'm also thrilled to be able to look at shots and learn what these critters are called and to carefully view their unique characteristics.
My Nikon camera/lenses that got me back into photography were due to my wife's persistence and she fully supported my switch to Canon, but what really made this feasible was inheritance that my dear mother left me. She's the one who instilled in me my love for God's creation and I know she'd be happy (although shocked at the cost) with my purchase.
