Circular is what you want; Linear polarizers don't play nicely with metering and AF systems. See this post

What he said...you want the circular polarizer.

mine would be the 16-35II currently but I'm hoping the fuji 10-24mm replaces it soon here. I've owned ~5 17-40s, ~3 12-24s, the nikon 16-35, 17-35 and 14-24 as well as the canon 10-22 and 20-25 as well as the older 16-35 I think? Yeah, I've tried them all basically (the sigma 10-20 [Both versions] now that I think of it)... But the 16-35ii is enough sharper than the other canon FF options it's the winner and I MUCH prefer being able to use filters the normal way -vs- having to punt with some super wide lenses like the nikon 14-24mm. The canon is also certainly sharp enough -vs- what they nay sayers like to say.

Ok thanks for that I will have a look at the 16-35 II

Nice photo`s of yours in this thread buy the way.

I just read through this entire thread. Great info!!!

A square CPL is really intriguing to me due to the fact that I don't have to worry about vignetting. I recently purchasing a Lee FK with Big Stopper and I've been venturing more and more into landscape photography.

However, I also like to do a lot of automotive photography. How would the 4x4 CPL's effect me removing reflections from windshields and the like? Will a 4x4 CPL limit me at all?

Also, I've been a HUGE fan of B+W/Schneider optics and I've definitely seen a difference between the B+W CPL's compared to cheaper alternatives. With that, I've been looking at the Schneider Circular True-Polarizing filter which was posted earlier in this thread. Does anyone have any feedback at all comparing the Lee 4x4 to the Schneider?

Thanks!

-Jalal

As far as the 4x4 goes for cars, assuming you aren't doing something weird with Grads at the same time, you'd just mount the polarizer as normal and rotate the holder a bit to get the reflections out of there. I don't see why it would limit you

Personally ive never found the square CPL limiting even with grads. The grads restrict you to 90 degree increments on the CPL but ive never found the need to have the CPL at 45 degrees (or any other angle from 0-90). Granted you could possibly add a bit more polarisation if you did have it set somewhere from 0-90 degrees but its so minimal I dont even worry about it

Here's my first test shot with the new Lee CPL. I really like it, and it's very easy to put on / remove. In the 90 degree fully polarized position it removed most of the glare from the glass, but added back in glare on the iPhone. Without it you couldn't see the reflection / glare on the iPhone. Must be something with that fancy gorilla glass.

I also added a small microfiber cloth to my Clik Elite filter holder so I can easily pull out the filter and not get fingerprints on it:

Maybe I'm not completely understanding the way a CPL works, but light reflects off objects different depending on their shape and their angle to the light source. So a CPL will always need to be adjust to remove glare from the object you are targeting. It won't simply remove glare from every object in the room that reflects.

This happens to me all the time when working with automobiles at car shows and the race track. You can remove the glare/reflection from one part of the car, but another part will still have it, and continually changes as you adjust the CPL.

So you can remove glare from the windshield, and as you continue to rotate the CPL, you'll start removing glare from the doors, and then the rear quarter, etc.

This is how I've always used screw on style CPL's.

This is correct and there is no advantage using a square CPL as opposed to a screw on CPL in terms of polarisation effect. The advantage of the square is that it slides in and out and is compatible with your other lee filters/holder etc

100% agreed and also because it will not vignette at 16-17mm (16-35L/17-40L). Both are issues that are important.

So now my other question...
Schneider 4x4 CPL or Lee 4x4 CPL?

Jalal - Good to know it doesn't vignette on the 16-35L. I've been thinking to upgrade from the 17-40L. Ben - how much sharper did you find the 16-35 over the 17-40?

For the Schneider, see post #269 in this thread. The Schneider is thicker and may not fit in the Lee holder:
