most of the time I find it a nuisance as you can't comfortably reach the edge of the filter to turn it.

I probably don’t understand the difference between “regular” (e.g., old-school “film” type) polarizers and “circular”. I do understand that you need a circular polarizer for digital cameras. But how do they work? My limited understanding tells me that you would NOT need to turn them as you used to do with the older ones. But I’m probably wrong about that.

One does need to turn a Cpl filter, to get the effect you are after. Just the same procedure as a linear polar' filter.

I tried my tulip type hood on my 55-250mm lens on top of my cpl filter and got no vignetting,but using my 18-135m wide angle lens I did get some vignetting from the corners of the hood(tulip) and could not eliminate this problem. How do I correct this on my wide angle lens. Thanks!!

One of my club members was using a lense hood over a polarizer filter on his camera?(dslr) Do you really need the lense hood in this situation(partially sunny or sunny day)? Thanks for your help!

Polarizers are not immune to creating lense flare. The hood is just extra protection for both the lense and filter along with helping to keep the sunlight off the front glass.

Another reason for the rubber lens hood, I had a slight bang with the attached lens hood and the elevator door closing.
Everything looked OK, but after going through the hotel lobby and on to breakfast, lost the lens hood. Could not find anywhere (probably broken anyway). Several of the hotel staff were on alert for the missing lens hood. Short answer GONE...
But fortunately I had as mentioned in my previous reply to this post a rubber lens hood, which added protection on the end of the lens, reduced flare, and worked well with my cpl as we were around water. The rubber hoods are cheap $10.00 +/- and fold easily for storage.

Nikon has a two part hood for their Polarizers. There is a scale on hood that indicates whether to use one or both parts of hood according to focal length. Never sorry to use hood only sorry when I dont use them.

As someone who uses a CPL a lot, I'm glad this was brought up. I typically don't use the lens hood due to the nuisance factor in adjusting with the hood on.

Neither do I. If flare is going on, I just shield the lens with my hand.

Tough to do while handholding Nikkor 300 f2.8. Just need an extra hand. Thanks for the thought.

Not if you use a tripod!

I don't often have a circular polarizer on the front of my 300 2.8.

You correct this by using a lens hood made for a wide angle lens - not one designed for a normal to telephoto lens. You are looking for a hood that is shallower and wider than what you have tried. I suggested earlier that you take take your lens, filter and body to the nearest camera shop and try the hoods on your equipment. There is no other way to get what you need without exhaustive and money wasting trial and error.

From my own experience a CPL and hood work well together. You get the most benefit from a CPL when you are shooting at 90 degrees to the sun. That is also the time when you need a hood the most. Canon seems to agree. The hood on my EF 100-400 L II has a small door built into it so that you can easily adjust the CPL with the hood on.

Does anyone use a Zune magnetic filter holder system for filters or their lens cap. I just recently tried the system and like it so far. Some might feel it is too expensive but is a judgement each of us has to make. I would encourage people to take a look at it.

On my Nikkor 300mm f/2.8, there is a slot mid barrel for inserting 40mm filters. A protruding notched wheel on the drop-in mount will allow me to rotate the polar filter while viewing.

Thus making the hood/polarizer interference problem moot.
