balanced when mounted on 1dx mk11,even with 2x extender

Durable; Rugged; Sharp Focus; Strong Construction

Condition was excellent and limited testing seems to agree with other owners appraisals. Though one reads the specs, it is almost a shock to see the actual size and feel the weight.

"Thanks to my mom and her generous monetary gift, I decided to spoil myself and purchase this lens. I love to photograph wildlife so this lens would make a great addition to my gear. I love that I can use my 2X extender and it did not interfere with the auto focus.

Image quality is amazing; very sharp; autofocus is very fast

Price is steep but worth it
