If you bought the 6D to use with a standard zoom to take standard photographs, that seems like a not-well-thought-out decision.  At the very least, you should be looking at poster sized prints, and...

...rather than advertise the limitations of the (useless) wifi, or making it useful in a firmware update, they release the actual camera they were advertising a few months later....and for some...

Two things that come to mind, maybe you are a little beyond infinite focus, and maybe this is the effects of atmospheric distortion (air and heat)

I think the combo you would love is the 7D with the 400 f/5.6, that is the perfect birding combo for hand held.  It would be difficult to get a single setup that is great in size-weight-performance...

I haven't used either lens, but I can tell you this. The 18-200 is basically an 18-55 that will zoom up to 200mm to catch what you think is an important photo of some animal that surprises you. It...

The other poster was right on about the Samyang 8mm for a great fisheye for the money. You might also want to consider the UWA Samyang 14mm that is also great value for money, easy to use, but...

There are some good iPhone and android apps too, many of them free.
