15mm Limited Polarizer

Anyone have any idea on which polarizer I would need for my Pentax 15mm limited?.

Well, it's got a 49mm filter thread, but be aware that using a CPL on a lens that wide gives a...unique look to the sky. Just something to be aware of.

Ok good to know. Would you recommend a filter?

There is no point in spending more for the slim frame polarisers - the DA15 doesn't suffer from vignetting from normal ones in the first place. Hoya, B+W and Heliopan are highly regarded makers

The B+W slim CPL actually fouls on the inside surface of the DA15s hood due to the knurling on the filter ring.
The standard version of the CPL filter is fine though.
B+W, Hoya (the Japan ones not the cheap Philippines one) , Marumi, Heliopan all good. Multicoated versions.
Kaesmann type are sealed to prevent moisture getting in between foils, maybe needed only in extreme condensing weather.

Vignetting is minimal. The CPL is on the lens in the pic with hood extended.

I use a 49 to 72mm converter and a 72mm Hoya Pro1 CPL I already had. No vignetting at all

As Finn suggested, be aware that the wide field of view of the DA15 will result in an uneven sky if you are planning to use the CPL to take panoramic images with clear skies. This is due to the fact that the level of polarisation of light varies with the angle away from the sun. Maximum effect of the CPL is at approx. 90 degrees to the sun and lessens either side of that. I reminded myself of this out about a week ago using the wide end of my Tamron 17-50mm with a CPL to photograph coastal scenes. Shorter focal lengths than say mid 20's mm increasingly produced an unnatural variation in the intensity of the blue sky. Longer focal lengths were fine.

Not so much of an issue though for cutting down reflections off close up subjects or with overcast but glare filled days.

This was taken with a DA21mm. A 15 would be even more pronounced. Just FYI...
