TAMRON SP 150-600mm F5-6.3 Di VC USD G2 CANON (Model A022)

[primetime]

Novice here. Apologies for the dumb questions, but how does this lens compare to other 150-600m options? Looking for something that can be had used in the $600-$700 range that can take detailed close-up pictures of birds, sometimes in flight.
Is this the lense to get or can better be had for similar price?

How does the speed of Canon variant lense compare when taking pictures of birds in flight?
How does the G2 compare to the A011?
This is for a Canon RF10, so I'm assuming the EF to RF mount is needed.
Not sure if they make 150-600mm F5-6.3 options that don't require the EF to RF mount?

I don't use big zoom lenses, but that sure looks like a nice one and it won't break the bank. When using Tamron lenses with a Canon EOS R series camera, the separate EF-EOS R Canon Mount Adapter is required. But considering that you may use other EF lenses some day, that's not terrible news.

Crop camera at 600mm you're going to need a tripod or at the least, use a monopod. You'll also need to start practicing smooth panning and tracking. LOL

I have this lens on an Canon 80D which is an EF mount. I use it for wildlife, It works well. Focus is good. A Canon lens would have better focus I'm sure. For the money I have been very happy with mine. I will point out that to zoom it turns the opposite direction of Canon lenses so it takes a little awareness when you shoot with it to remember to turn the other way.
