This matches MSL Mastcam Left then Correct. Original MCZ spec was for 34mm to 100mm but we ended up with some extra credit range and can do 26mm to 110mm. Typically values 26, 34, 48, 63, 79, 100, and 110 will be used, but AFAIK nobody is sure yet how they'll be chosen. Zoom has to be stowed at 26mm for driving, so that might motivate use of that setting sometimes. -------------------- Disclaimer: This post is based on public information only.
