Tokina's updated 11-16mm f/2.8 for APS-C — CF coating and improved internals over the original.
The Tokina atx-i 11-16mm f/2.8 CF is the updated version of Tokina's popular APS-C ultra-wide zoom, adding CF (Clear Front) coating on the front element for easier cleaning and improved scratch resistance over the original Pro DX.
Same optical formula as the AT-X 11-16mm f/2.8 Pro DX — sharp with constant f/2.8 for astrophotography on APS-C. The CF front coating is the main practical improvement. One-touch focus clutch. 77mm filter thread.
Available for Canon EF-S and Nikon F DX mounts. 77mm filter thread — accepts standard filters. Approximately 555g. No weather sealing. CF front coating. 16.5-24mm equivalent on APS-C. The narrow 11-16mm range is the main limitation.
Available used at mid-range prices. The CF coating addresses the original's glass cleaning difficulty. Same optical quality — proven and respected. The 11-16mm range is narrow but the constant f/2.8 is excellent for astrophotography.
