  1. Now I need to track down someone who has a dock to update mine I guess. I hope this resolves the issue with the Irix 15mm and my Canon TS-e lenses where if you are shooting a bracket it shoots the first one at say f14 or whatever you have chosen and then it slams open the aperture to f4 for the rest of the bracketed shots.

    1. The dock is for lenses. MC-11 updates via USB. Bear in mind that unlike Metabones, Sigma doesn’t test compatibility with Canon lenses – only Sigma.

  2. For sure. This is why I have both. The MC-11 does NOT work with the IRIX 15mm f2.5 or the Canon TS-e lenses. If you are bracketing (as I often do with architectural) the first shot is taken at the correct f14 or whatever… then the mount slams the aperture wide open for the remainder of the bracket ruining the bracket.
