A Wildlife Photographer's Guide to the Sony 135 f/1.8 GM Lens

I was able to beg & borrow, though unsuccessfully steal, a drool-worthy Sony 135 mm f/1.8 lens for our South Island NZ trip earlier this year. I’ve finally gotten around to writing up my observations on Nature Tripper: Sony 135 f/1.8 GM Lens: Wildlife Photography Notes.
I’m hoping to borrow the lens again for my Queensland work and will add additional Sony gear guides over time.
