LEE "Square" Circular Polarising Filter

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:

Jamil, I'm actually not 100% sure if it does or doesn't so don't quote me. I thought I read in this thread somewhere that people did not have issues at 16-17mm. Someone please correct me if I misspoke.

I noticed the 4mm thickness in that post which is double the Lee. I know Lee sells a 4mm guide for their FK's so I planned on picking one up if I went with the Schneider. However, some reviews on B&H mention the stubs on the 4mm guides not lining up with the indents on the 2mm guides. Idk that it would really deter me since you have a screw holding it down regardless. I'd also have to double check to see if I need the longer screws they sell as well.

My foundation kit came with the longer screws that I used to make it a 3 filter holder. You can pick up some even longer ones if needed at your local hardware store. I usually get the stainless steel screws for stuff like this.

And if B&H is out of stock, I highly recommend 2filter.com

2filter.com is exactly where I ordered my FK & Big Stopper!

I know I will definitely need a G4 filter guide for the Schneider if I go with that. They also have the various Lee screws listed, so I'd probably just order them as well so that it all matches up.

Last night I remember seeing them listed somewhere else, too, where there was a photo of the screws but I cannot remember for the life of me.

the 4x4 CP will not vignette on the 16-35II @ 16mm. Trust me, or just go check out my flickr stream.... I use it all the time. I've seen the 105mm option once, it vignetted on a 24-70...

JBen - how much sharper did you find the 16-35 over the 17-40?

Well, to be fair I got it when I got my 5Diii because I wanted a 2.8 zoom to pair with the insane ISOs that come with the 5Diii. But I HAVE noticed a step up in sharpness in my images since that switch. Hard to say how much is the lens -vs- the body but I'd put money on it being the lens. I'm a whore lens wise so I've tried them all. I did NOT want to like the 16-35ii (because it's bigger and more expensive) but it's a keeper.

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?

the only limit with the 4x4 CPL with cars is if you're at a show the panel and holder are a lot bigger on the front of your lens -vs- say a 77 or 82mm round CP. So they could get knocked off in a crowd basically. If you're going to own one, get the 4x4 setup and just be careful. I'd tie a leash to it and the lens so if it falls off it won't hit the ground?

I kept my 77mm filters only because they're not worth enough selling used to make it worth losing them in case I ever need them. They're also very nice when shooting waterfalls when all you want is a CP because you can only get water on the outside of the filter, not both sides of it AND the lens...

Thanks, Ben. Before I got the Lee setup, I was going to get a B+W 77mm Kaessman MRC CPL. Possibly even an 82mm with an adapter so that I wouldn't have to worry about vingetting. But since I do have the Lee FK, I'll be getting a 4x4 since I like how fool proof it is.

Now, for a CPL - Lee or Schneider ?!

That's exactly why I have both.

Thanks for the info. It's hard to say if the 1 stop of light and 1mm focal length wider is worth the upgrade, especially considering I mainly use this lens stopped down on a tripod. I love how small and light the 17-40 is.

it's not an easy decision, but even being a cheap weight weenie I'm still glad to have the 16-35II now that I have it. But if you're happy with the 17-40 just don't ever try a 16-35 and you'll be happy.

When I upgraded from the 24-105 to the 24-70 II it was a night and day difference in sharpness, distortion, and build quality / lens feel. I don't think it will be as big a difference in this case. I could always test them out side by side and decide.

I'd bet you're right (that the 24-105 step up to the II version is bigger).

This great article just saved me some money:

OK...back on topic. Hope to use the CPL tomorrow on my vacation.

Here is one of my first good shots using the Lee square CP:

Nice! Im a sucker for that type of shot. You nailed it

Thank you! Much appreciated!

And regarding the square CP, I'm finding it's totally usable (as this topic confirms) in the square format. In this case, I had the lettering on the filter in the top position. I find it works best either in the top position or the right position.
