Sony will have a press event on April 24 at 9am PDT time. I am not sure if they will announce the new 24-70mm GM II on that day. But here are the rumored lens characteristics:
- it’s extremely sharp
- designed like the current 70-200 GM II
- it’s the lightest 24-70mm f/2.8 on the market
- it’s also smaller than the previous version
