Along with Sony a1II, Sony will announce a new FE 28-70mm f/2.0 GM lens on November 19th. It will cost around $3000. And much lighter than Canon's RF 28-70mm f/2L USM lens.
Honestly three grand for a single lens sounds totally wild to me. I remember when I first started out and thought I needed the absolute top tier gear to get good shots. I ended up lugging around a heavy setup that just sat in my bag most of the time because it was too bulky for a casual day out. I would suggest being really careful before dropping that kind of cash on this new 28-70mm when it drops on the 19th. You might want to consider something like the Tamron 28-75mm f/2.8 Di III VXD G2 instead. Its way cheaper, usually under nine hundred bucks, and for most people the f/2.0 aperture isnt worth the extra two thousand dollars. I once spent way too much on a fast prime and barely noticed the difference in my daily photos. If you really want Sony quality, I'd look at the Sony FE 24-70mm f/2.8 GM II because its already light and sharp. Just make sure to think about the weight... even if Sony says its lighter than the Canon, its still gonna be a brick to carry around all day. I'll be watching the announcement but mostly just out of curiosity... my wallet definitely isnt ready for this one.
