I’ve used the 28-60 + wwl-1b on my A1 extensively over the last 9 months and they’re a fantastic combo. Autofocus is quick and reliable and the images are tack sharp. What I love the most about this setup is it’s flexibility. ~80% of my shots are taken at 28mm with the WWL-1 on, but when I need a bit of zoom to reframe smaller subjects I can zoom through to 60mm behind the WWL-1 (15% of shots) or even take the WWL-1 off for fish portraits (5% of shots). If I have strict baggage allowances on a trip this is the one lens combo I’ll take. If I’ve got more wiggle room in my luggage I’ll also throw in a Sony 90mm macro lens and a Canon 8-15mm fisheye. If I’ve got both, I pick and choose between the 28-60 and the fisheye based on the subject matter, whether I want to do split shots, etc., but they both take beautiful images.
I’ve pulled together some sample images from the last 9 months here if you’re interested: https://www.shanesmith.photos/Recent-Adventures/Underwater-2022/Sony-28-60mm-Sample-Gallery
