Hey Dustin,
Great review, as always. I'm on the cusp of buying this lens, but one thing keeps bothering me. I use the Eg-S screen in my 6D for my fast primes and love it, even indoors, but I absolutely hate the idea of having to take it out if I'm switching lenses (I know, I'm lazy). I remember you saying you used the EG-S screen. Have you every used the 70-300 L with the screen installed? I'm going to Iceland in December, and I want a telephoto zoom for landscapes. I'd use the 70-300 outdoors in daylight and never past sunset, so I was wondering if you think I could get away with leaving the darker focusing screen in for those shooting conditions.
I'll probably buy the lens anyway, but I was curious. Thanks!
