Re: Lens purchase decision - advice please


My 100-400L II arrived today, and.....  It's going right back tomorrow to my local shop where I bought it for an exchange.  Something is way out of whack.  It's extremely soft at any focal length, and it's missing focus.  When I test focus speed, it's slower than an original EF-S 75-300!

The only thing I can think of is something happened during shipping, and either some elements shifted or something.  It was packed very well with a lot of shipping material inside to cushion it, but there was a small gash in the outer box.

I already spoke with the camera shop (they're amazing, BTW) and they put another one aside for me when I get there tomorrow.  I tested it on my 77D and my wife's T3i, and there is definitely something wrong.

Ugh... nothing more disappointing when you spend a good amount of money on professional gear, and it doesn't work.  I still have high hopes, as the one I rented in August for my Yellowstone trip was amazing.

Here's a few shots to show what I mean.

Just checking the focus points
