Frequently asked questions
What filter size does the Canon EF 16-35mm f/2.8L III use?
It uses 82mm filters, matching the previous generation and the 24-70mm f/2.8L II, so landscape shooters can share filters between the two.
Is the EF 16-35mm f/2.8L III good for astrophotography?
Yes. The f/2.8 aperture and wide field suit night-sky shooting, and the III has improved corner performance over the II.
EF 16-35 f/2.8L III vs f/4L IS: which should I buy?
The f/2.8 is faster. The f/4L IS is lighter and stabilized, which helps in handheld video.
