Can polariser ruin shots?

Just one point that probably has little bearing on the AF issue - The Nifty 250 has a rotating front element. That means that once you adjust the polarizer the way you want it, it will change when you focus.

Personally i would rather have just used a Marumi 2 stop ND filter to eliminate the haze since the positioning of the Sun would be no factor in relation to the target capture. Of course just like the CPL you would still have to re-position the filter after pre-focusing since the lens rotates during AF.

Check out my post here about a similar bad experience with an inexpensive polarizer I picked up.

How could an ND filter eliminate haze?

Heck, it's hard enough to cut haze even with a polarizer ! This shot was taken yesterday ( very hot and humid/somewhat hazy here ) from out on the golf course. This house ( yes, it's a private residence ) is about 1 click away, and was shot with a polarizer in the 300 2.8

BTW Nice House !

Looked in my bag and the one below is what i use which is actually a Marumi GC color effect filter that can be used to cut the glare from the harsh Sun or the glare off the water depending on how you spin it. It does a pretty good job when my target is not suitable to use a polarizer in relation to the Sun position early & late:

I use it with the 70-200MKII down here in these bright hot Texas days we get most of the time.

I figured a way to post some of the shots I was talking about. They are attached in the links below,

Having looked at one of your images, it has a softness that I would attribute to the use of a poor quality filter. It's not subject motion or a slow shutter speed as you've stopped water drops in mid-air. It's not missed focus as the image is uniformly soft.

My suggestion would be just to leave the filter at home for a while and see how you get on. A CPL is really something that should be used only when circumstances specifically require it. In shots like this, having the water reflect the blue sky (if it is indeed blue), can actually be useful.

Thanks Xarqi. I will take your advice. The CPL is indeed cheap and I never had this before using it. That was kind of what I thought but also suspected it could be a problem with my camera or lens. Your explanation makes more sense

I have a Lee 105mm circular polarizer which I use on the Lee filter system. With the Lee adapter rings it can be used on any lens and it is superb! No negative effect on IQ. If fact it really produces spectacular results. Highly recommended!

Please do not post pictures of my guest house up again.

Oh....sorry....I thought it was just the maid's quarters...
