f/5 is a no go for me on a long lens. f/6.3 is even more of a no go, but that's just me.![]()

I'll save my $$$$$ for a 400 f/2.8 with a 1.4X or 2X. They are once in a lifetime purchases that can be handed down.
sigma 200-500/2.8 EX aka "Sigzilla". even a dedicated f/2x extender comes with it.

i fully understand what you say and sympathize with it. light is paramount. aperture rulez!
but it's all about the money.
and the size of front element and size of lens.
and weight of lens.
also, extenders are no free lunch. they eat light! a 400/2.8 with 2x extender turns into an 800 f/5.6 lens.
pretty dark, man!
but rejoice, there is good news! a constant f/2.8 SUPER tele zoom lens is waiting for you and the EF mount of your Canon mirroslappers.

on stock at amazon abd elsewhere. usd 25,999 with free shipping.
hope you got the wallet for it. and the bizeps!
yes, it can be handed down to sons and sons of sons. with an optional adapter they can easily convert it to a mobile missile launcher if and when needed.
lol, man!
and: lenses are no hand-me down items. except as cup board decoration and rather substantial paperweight. canon ef lenses will only be usable with an adapter max 10 years from now when the last mirrorslapper is retired. much like canon fd glass in 1987. and 20 years from now nobody in their right mind will lug around big fat abd yet slow and dark lenses. for imaging those of us who are still alice then will use tiny nano lightfield cameras with some non-glass microlenses in them. or similar.
Yeah, a 2.8 at that focal length is what I meant. :

An 800mm at f/5.6 is far better than a 150-600 with variable aperture and as dark as 6.3mm. I have no desire for 800mm, but if I did... I guess f/5.6 at that focal range wouldn't bother me. However, with 115 degree temps atmospheric conditions don't work for that.
I have a Tamron. I don't like this one in the post... for the very reasons I stated.
Keep slapping it AvTm. You'll never get no satisfaction.
