Wonderful, Patrick. These filters really 're-create' the landscape.
Do you perhaps know if Lee has the filters for the Sigma 12-24 too ?
Hi John, thanks for commenting,appreciate it!
And yes, LEE Filters do make the SW150 MkII for Sigma 12-24mm f4.5-5.6 DG HSM II too, and also;
Nikon AF-S Nikkor 14-24mm f/2.8G ED (as I'm using)
Nikon 14mm f2.8 D AF ED
Canon EF 14mm f2.8 L II USM
Samyang 14mm f/2.8 ED AS IF UMC
Tokina AT-X 16-28mm f/2.8 PRO FX
I also know that additional lenses will be added soon.
And a little advice, I must say that if you haven't had much experience with shooting with ND filters, I would recommend you to stay away from those heavy duty 6 and 10 stop filters to start with and rather start of with a "normal density" ND as f.e. a PRO glass ND which you can get from 2 and 3 stops. Many new beginners of ND filters starts of with a Big Stopper which is between 9 1/3 and 10 2/3 stops, which is not a good idea if one really wants to learn the ND filter "process" from scratch.
Feel free to contact me for further questions, I'll be glad to help! (send me a PM)
