Here are a few bird photos taken at random. 300mm /2.8 II + 2xTCIII on 5DIII. Usually f/5.6 and iso 640

Good night Madam
My dear friend Surapon, you forgot I'm male (MRS are my initials)- but what's in a name
Many people here make the same mistake, so I updated my avatar awhile ago as a hint to my gender
Sharpness really isn't critical beyond a certain point, so long as you have the right length lens for the job and have time to perfectly compose the shot. Where sharpness starts to matter is when you don't have that chance, and you have to crop after the fact. So basically, I care a lot about sharpness in whatever lens I choose to keep on my camera by default, and I don't care nearly as much about sharpness on the other lenses in my arsenal—except for the long zooms when I'm taking photos of birds; then I care again, because I don't own a $14,000 behemoth lens....
Love this topic! Awesome eagle shots CT John!
You do realise, that f/4 on FF is still thinner DoF than f/2.8 on APS-C, right?
This is incorrect. A lens mounted on full frame or crop will deliver the same dof at the same aperture. Ie if you mount a 50 1.4 on a 70d or a 6d both will have the same dof. It's the same glass. But the angle of view will obviously be a lot wider on 6d
While I can hand hold a 300 f/2.8 ii + 2x TC with IS, I will tell you that using a tripod is better at that focal length. The Tamron is about 1.5 pounds lighter than that combo but I can tell you that there still are times when a tripod is a great tool. Having only recently gone to a Gimbal head, I'd really recommend it over a Ballhead unless travel weight is a limiting factor. I am biased but I like the Lensmaster RH-2 for it's size, simplicity and price.
