There has been a bit more talk about the upcoming Canon EF 70-300 f/4-5.6 IS II. We haven't yet nailed down the announcement date, but all indications say it will be before Photokina in September.
We're told the new lens will have a “digital display” like the Zeiss Batis lenses, what information is on that display is unknown at this time. The lens will also feature nano usm.
We're also told that the new version is slightly heavier than the previous version due to the front element and has a “stubbier” design.
More to come…
