500mm for your Rebel T3i? The same 500mm that applies to all Canon EOS bodies: EF 500mm f/4L IS II USM, a $9000, 7 lb monster that works best with a tripod and gimbal for a stable platform, or at least a monopod, although can be hand-held if you have the arms for it.
For more economical lenses, have a look at used and / or older, discontinued models.
I agree. I have an EF500 f/4L IS USM. It’s a monster of a lens but it’s only second best to the Mark II and the new 600mm lenses. But for the money I think the new 100-400 Canon lens is the best especially for someone just starting out with their first long lens.
