Polarizing filter help

Just noticed in the OP..... there is no glare to reduce.... those are reflections. But still a CP will help.

I'm still confused. I also took some shots with other lenses without the filter (85mm and a 100-300mm) and none of them have that distorted look. Is it because I was at a different angle with those lenses?

Here's one with an unfiltered 85mm.

I'm not clear what distortion you are referring to.
Can you elaborate on what you mean by distortion?

Thanks

I'm sorry - I don't know how to describe it. What I'm referring to is most easily seen in the picture in post #1, where the reflection of the blue sky in the windows has a distorted, rippled effect, instead of a crisp, clear, smooth blue as in the first picture of post 16. Hope that makes sense...

Yep, sometimes you get those lines (looks like a sort of rainbow grid) on certain building or aeroplane windows when using a polarizer due to cross polarisation.

See here and here

You may need to re-state your question.

But here are a few answers at random.

You say "glare" but are asking about reflections. Polarizing filters are to help reduce reflections. So why are you taking pictures of reflections as a subject, but useing a polarizer?

If you are asking about why the reflections are full of waves....it is because glass is not really flat. The farther the object is from the glass the more apparent this is. Example. If you put a model, leaning agenst the window you will not see much distortion, But try to take a shot of the distant horison in the reflection it will be all messed up. Our brains can adjust for this. This is why we dont overly notice it live. The same way our brain can adjust white ballence. White looks white in Flouresent, Tungsten, incandesent, and sunlight. Enen though our eyes are not sending that signal.

It can be as qtaran111 stated. The filter may be producing a Moray effect.

Not only is glass not perfectly flat, but the different panes of glass (glazings) are often not perfectly parallel to each other - which in effect means that the "mirror" is not flat - this also results in distortion.
