On October 3, 2019 Sony announced the second iteration of their flagship full frame camera – A9II. Looking at the specifications we get the impression that it is just an incremental upgrade over the A9. Or is it?

From the day Sony announced their 135mm f/1.8 GM lens I was wondering if it will be a better option for me to replace the 70-200mm f/2.8 GM. Being smaller, lighter and faster – that sounded like a good option. Plus, on my A7RIII or A7RIV, with just one click (switching to crop mode) it turns to a 200mm lens. For my casual shooting I wouldn’t even think about this. But for professional work – like weddings and other events, the versatility of the zoom lens is a king. However, the new 135mm has a faster Dual front and rear XD linear motors to achieve fast, precise, and quiet AF. It also have smaller minimum focus distance and aperture dial on the lens.
