Opinions on a B+W Cr Pl

[HDNitehawk]

• Does the slim really make a difference on the ultra wide lenses?
• Does the Kaesemann really make a difference over the non-kaesemann?
• Can I stack ontop of the slim filter?
• Does have it vignetting? I can't find an answer on this
• Is it worth the extra $100 that I paid for my Tiffen and over the second B+W filter I listed?

• You don't need the slim, the only benefit would be if you were stacking the filter. If you were using a wider lens like the 16-35mm the slim version would be more important.
• I would go for the Kaesemann
• Some are not, here are the designations.

  Mount Name	Mount Color	Non-Polarizers	Polarizers
  F-Pro (front threads)	Black	5mm	7mm
  Digital-Pro (front threads)	Brushed Chrome	5mm	7mm
  Slim-Line (no front threads)	Black	3mm	*5mm
  XS-Pro Digital (front threads)	Black	3.4mm	4mm
  Extra-Wide (front threads)	Black	Call	Call

• Neither should vignette on the 24mm. When you start stacking several filters it may, are you using a FF camera? 2 normal filters you would probably be ok. Go to 3 on a full frame body and you may start to see it depending on what your stacking of course.
• It isn't worth $100 if your family goes without food because of it. It is worth it if you want something that gives a little better IQ and do not mind paying the extra $$$. Whether it is worth it or not is a individual perception. To me it is.

EDIT: I have this one;

+1 for the Nano technology.

I have two other B+W's one slim one not. The one above is the best.
