Nanuk 918 Hard Case (Silver, 20.6L)

Yes.

The DZOFilm VESPID 6-Lens Kit A (PL & EF Mounts), B&H # DZVKAPLM, would be too large for the foam inserts. The alternative would be the DZOFilm 4-Lens Hard Case for VESPID Primes (B&H # DZOCASEV4). https://bhpho.to/3zLO0aL

Yes it will. You could place multiple of that lens in this case.

Based on the measurements it would be a very tight fit and not recommended. Another choice that would work is https://bhpho.to/39ftveq

While the manufacturer does not list the diameter of the lens cavity, it can easily hold a lens that is 3" or smaller in diameter. So those lenses lenses all should fit.

A Canon 24-105mm f/4L would be the largest lens it can hold.

don't buy this case. not enough flexibility for different types of lenses. just don't.

Unfortunately no. The size for each lens in the Nanuk 918 Case with Foam Insert for Set of Six Lenses is 4 inches by 8.5 inches and the Leitz Summicron C lenses are larger than 4 inches in diameter. I would recommend either the foam insert version https://bhpho.to/3eztYYT or the divider version: https://bhpho.to/36Rfyil The Divider version is more adaptable in case you change which lenses or other accessories you might be carrying.
