At Sony Kando 1.0 in May, I was able to play with new Sony 12-24/4 G lens along with a Sony a9.
With really wide lenses I like to shoot landscapes, especially with foreground elements. This was on the hill behind El Capitan Resort in Santa Barbara where we all stayed.
Sun stars looked great with the lens.
I found the lens to be very sharp, and really quite compact. I was quite pleased with the lens and definitely plan on buying it when it becomes available in a few weeks!
