CAMERAS AND LENSES I OWN
This camera has f/8 autofocus with a 1.4x extender, meaning I can use a 1.4x teleconverter on an f/5.6 lens and retain autofocus, however I find that it is not fast or accurate enough at focusing, at least for bird photography. Overall, I have no real complaints about this body and it is an exceptional tool for bird and wildlife photography.
Canon EOS 60D
The Canon EOS 60D was my main DSLR body before I upgraded to the 7D Mark II in late 2014. It worked very well for me. While it doesn't have the 10 fps, 61 autofocus points or the ISO performance of the 7D Mark II, it was still a great camera for me and was considered to quite good at it's time. I found I could use it to ISO 640 or sometimes 800 and get very usable images with not too much noise. This is still a great camera and is my secondary/backup body.
Canon EOS Rebel T1i
Canon EF 400mm f/5.6L USM
I've spent only short amounts time with the equipment below, ranging from a few minutes to try it out to a week or so of use.
In rare cases I use a Sigma EF-610 DG Super Flash and when I use the flash, I usually use it on a Vello flash bracket. Usually I use my equipment on a Milano Carbon Fiber tripod with a ballhead, or if I am renting a larger lens I'll use my gimbal head. To spot the birds and wildlife I photograph, I use Vortex 8x42 Diamondback Binoculars and an Olivon spotting scope.
