Sigma has released a set of firmware updates for its Art lenses for Sony E-mount cameras. The upgrade improves AF speed, Face Detection accuracy, and fixes other minor AF glitches.
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.
