I was looking for a lens one step longer than my 70 to 300mm. This is it. I've used it for bird watching with a tripod. Camera and lens together are only 5 pounds. Simple to use. Satisfying results.
I got very helpful advice from your Best Buy salesman on this, too.
Thank you.

This lens focuses very close giving you an almost macro type of result. The image stabilization is like nothing else. Best money I have spent.

This has become my go-to telephoto lens and has served very nicely as a macro lens in a pinch because of its very close near-focus capability. Tack-sharp and with the latest Canon IS tech, it's totally reliable in any focus mode under just about any shooting circumstance. Love it.

Coupled with the 7D Mark II this lens is fantastic for birding. It was a little soft at the ends out of the box but nothing a little MFA couldn't take care of. Once I did that it performs like a champ.
