Welcome back
In honor of my 70–300mm babby coming back from the shop, I took a test picture on this cloudy morning, in my dimly lit apartment, from across the room, with the flash on.
It lives!
According to the repair report, the aperture assembly needed adjustment or replacement. They also threw in some general checking and adjusting. Thank you so much, six year warranty. My babby was out of my hands for just over two weeks, which—considering that most of that was shipping back and forth, A-AND it was over Thanksgiving—is a pretty quick turnaround.
