Any workaround for getting a CP on the 14-24

Go to last post
Very unlikely. The filter would probably have to be gigantic and would produce uneven shading in photos.

I have wondered if someone might make a neutral menicus lens to be used as a protective filter for the 14-24. It would be horribly expensive, I am sure, but the high price and popularity of the 14-24 might make it commercially viable. It would probably seriously degrade image quality though.
 
I just ordered at B&H a Schneider True-Polarizer 138mm.

http://www.bhphotovideo.com/c/product/398871-REG/Schneider_68013038_138_mm_True_Polarizing_Water.html

It is designed for video cameras but it's supposed to be one of the best, hence I guess it should work fine also for photography (Schneider optics are usually top class).

I bought the non-linear one because it is 100$ less (still almost 300$...) and giving I'll mostly use it while on tripod I don't need the AF to work.

I bought the 138mm filter because even if the lens has a diameter of 98mm the integrated hood pulls ahead the plane of the filter so you'd get vignetting at the right/left edges with a 105mm filter (and I hope I won't get vignetting with the 138mm also...).

Polarizing the sky at 14mm is not advisable, but the lens goes to 24mm so at the longer settings it would be nice to have the option.

Anyway I got it mostly to reduce reflections in foliage and water, not to darken the sky (something you can easily do in PS).
 
The lens doesn't protrude past the hood at any zoom, so you could use rubber bands or some such taped to the edges of the filter to hold it against the hood. The hood would be resting on the filters glass, but hand holding would get old real fast I'd guess.
 
sorry to bother but what does the abbreveation CP mean, i see it around quite often
 
Hand holding a GND could be beneficial on a long exposure. You could dodge like the old darkroom days to feather the effect further, or cover both angels of a steep mountain range that don't work as well with the straight graduation.

You could even use a CP at the wide end and hand rotate to equal out the uneven effect on the sky, although it would also lessen the effect overall. Since it's not attached to the lens, no camera movement.

They're called "dome ports". You can get them from Ikelite, Seabell, etc.

Normally, a signature this small can't open its own jumpgate.

I just got the 138mm Schneider True-Pola from B&H.

Sadly it works badly with the 14-24.

First of all it's not very effective as a photographic polarizer, my B+W polarizes MUCH more.

You have also to rotate the whole filter because it isn't built in two parts (one threaded and fixed, the other rotatable) it's just a single piece like an UV filter, so it's a little more awkawrd to use.

I get slight vignetting even at 20mm, but the most important drawback is that it gives many reflections on the image, probably because there's always some space between the filter and the spherical frontal element, but also because it doesn't seem a very good optically filter per-se also... just look through it with the naked eye and it's almost impossible not to reflect your own face...

In the end... worst 290 $ buy in my life... even worse because it was a special order hence not returnable/exchangeable :(

I hope that Lee would find a better solution.
 
lee filters have solution this month , but i bought spare cover and hacked 95mm hole out to accept a hoya , full frame camera d700 should have spare in case of any corner vingetting...Nik Onman
 
Couple days ago I saw on one of Nikon users webside, someone used the Lee filter attached to the flange (yep, you read that right "toilet flange") and he claimed it works OK.. YMMV

Now I'm wondering what to do for filter use, especially the CP.

I don't think you want a polarizer on that wide angle of a lens. I've got several deliberate bad examples from my Sigma10-20.
