Sorry to revive this old thread, but I'm considering getting the wonderpana for the 17 myself and am a bit confused
Is this 145 Essential Kit custom made for the different lenses (like the Nikon 14-24, the Canon 17 TS, etc.) or will the same kit work with all of them? Particularly I'm wondering if the same kit will work for the 17 and the samyang 14 mm - and possibly the 16-38 2.8 II.
The kit for the 17 TS-E is custom, I strongly suspect all the others are too.
I have thought about making a convertor for the 17TS-E version to an 82mm thread, that shouldn't be too difficult and would give me more flexibility, but I haven't gotten round to it yet. But I don't see a way of making it fit the other lenses with petal shaped hoods/ends.
It might be worth a call to Fotodiox to ask how the core units fit to the filter holder, it is a bayonet mount, and you might find they will sell you the core units (the bits that attach to the lens) and you only need one filter holder for the Samyang and the 16-35, but I still don't see how that could interface with the unique lens cap mount bayonet arrangement they have for the TS-E.
