You have very eloquently summarized the down side of said lense for us "Old Guys".
"Silent" who knows after her Majesties Naval Guns have fired 20' from your ears or after spending 8 hours a day 4000' underground listening to the scream of a 4 cylinder JV Diamond Drill. Back when Men where Men and didn't need ear protection ! I have a Bigma 150-500 DC and miss 115% of my shots because I'm always looking at the big end to see and make sure if its turning while trying to focus on that distant prize.
I've even tried putting beach sand down the big end so I can hear it turning ; then it stops turning altogether. "Accurate" How do we know? We're looking through our good eye that's being adjusted by the broken end of a beer bottle at an image this big
. "Faster" hardly f4.5 - 6.3 up against the Super Fast f4 - 5.8 of the 55-300 Screwd Drive
Sincerely
Some Old Guys
