Damaged Lens

March 20, 2021

I think this Canon EF 70-200mm f/2.8L USM  remains the most expensive lens I have ever purchased. Sadly (OK, heartbreakingly) it fell off the tripod a couple of years ago.





As you can see the glass is intact but manual focus and zoom are now very tight. They can move but not without a great deal of effort. Meanwhile, autofocus appears to be unaffected. I snapped the below shots with Canon T6s in JPG "L" mode. They are unmodified except by scale and/or cropping. 
Note: this lens can work with the Canon 1.4 extender (see below).



Approx 9.5 feet, cropped and scaled 50%.

Approx 43 feet, cropped and scaled 80%.
IMG_6920 1/320 sec. f/7.1 190mm ISO 100
