"Slim" Filters?

[MPG Photography]

Sorry in advance for the rookie question... :cool:

I am in the market for a circular polarizing filter for my 28-135mm IS lens.

I know the slim filters are specially made for the "wide angle" lenses, but is it benificial on the above mentioned lens to pay the extra $$$ for the slim filter?

I will be using the lens on my DRebel so with the 1.6x factor the 28mm isn't really a wide angle IMO.

If you were putting a very wide angle lens onto a film camera (full frame), then the use of a slim filter makes some sense. Extra cost, but it makes some sense.

If you were putting the same lens onto a Digital Rebel, then it makes much less sense, due to the reduced sensor size. In essense, you aren't using the very outer edge of the lens or filter anyway, so whether there is a lip of filter there or not is irrelevant.

It makes a difference on a 16-35 mm lense with a 1Ds but not a 1D. The cropping effect on the 1.4 and 1.6 factor cameras cuts off the vignetting.

Has anyone actually check this out??

I have a 1Ds and the 16-35 2.8L and I bought just a regular circular polorized fileter (didn't know any better). I've only used it with the filter a couple of times (don't remember if it was at 16mm or not) but definatly don't remeber any problems.

One other point that I noticed with the same lens and filter, if you buy the regular filter, you can still use your lens cap. If you get the "slim" version, you cannot(I least I couldn't!). Since I like leaving the polarizing filter and lens cap on when I"m out shooting, I prefer the non-"slim version"

I just ordered a B+W 77mm slim UV filter does anyone know if a lense cap can be used with this model? I never thought this might be a problem.

B+W slim filters have no front threads so you will not be able to use a standard lens cap. as stated above if you don't have a full frame camera you should have bought a regular one. i think there are some other types of caps, if you look around. you may want to exchange it though.

I used a normal B&W cir. pol. on my 17-40 with a film camera and even wide open saw no vingetting, but when I used my B&W normal red filter and the pol. I got a little vin. So I tyhink you will have no problems with a normal filter

B+W are very thoughtful people they include a lens cap with the slim filter, so problem solved. I use film so thought the slim filter was the way to go.
