Well, yesterday I went out the the Isenberg Crane Reserve (near Stockton, CA) to take a Department of Fish & Game tour of the reserve as it's now Sandhill season. I've shot Sandhills in the Central Valley before, so I pretty much knew the drill.
Sadly, the weather on Sunday was too nice, and most of the Sandhills did their fly-in very late in the evening. There was very little light to work with.
I also, for the first time, decided to try my Canon 400mm f/5.6L lens with the cheapo Tamron 1.4X extender. Others have claimed good results with this combo, and even though I already have the Canon 1.4x, you need to tape the pins for auto-focus, and even then, it performs very poorly as far as auto-focus is concerned (on a 20D). The good news is that with the Tamron, the 400 focuses much more quickly than it does with a taped Canon 1.4x. It's not nearly as fast as without it, but decent enough to do some birds in flight (as long as they don't fly too fast
).
However, the bad news is that it really cuts the contrast of this great lens a LOT. Far too much for my tastes. Now, first 2 images below are shot with that combo, and the contrast looks fine. That's because I processed them in Photoshop to return the contrast. They were both taken in excellent, contrasty light though, making the PS treatment do-able. The images I shot with this combo in non-ideal light were not useable. That would be most of my Sandhill shots, so you're not going to see any Sandhills taken with that combo in this post.

The next 2 were taken with my 70-200 f/2.8L IS, and I sort of like 'em
