Circular Polarizing Filter and long Telezoom lenses (Page 2): Got a Dremel tool? Cut out a small section of the hood so that you can use your fingernail to rotate the filter, as others...

Got a Dremel tool? Cut out a small section of the hood so that you can use your fingernail to rotate the filter, as others have done. Putting the cutout on the bottom greatly reduces the chance of any light entering. My Canon 100-400 has a sliding door built into the hood for adjusting the filter. I believe some aftermarket hoods have the same feature. Rubber hoods that screw into the filter so that you can adjust the filter by turning the hood are a less desirable option, IMO. They are often much smaller then the original and can be quite hard to find for the larger filters. BTW, in case you aren't aware of this, larger Cir-Pl filters often have cromatic issues. For the size you need, buy a very high quality one, such as a B+W.

Suggestions and comments appreciated.

This threads on the CP filter and turns with it to adjust.

Thank you for replying. I would like to rephrase my question: How does one operate the Circular polarizing filter with the lens hood attached...the lens hood on the Tamron and or Sigma 150-600mm lens is long, the Circular polarizing filter needs to be rotated to get the desired effect and the lens hood obstructs ones' ability to rotate the filter ?

With my 28-300mm lens, I can reach in with one finger and rotate the polarizer.

First off.....a 95mm CPL is very pricey and the Tammy is a slow lens to begin with. I bought the only one I could afford, a Sigma......and I haven't used it yet!!! $295 for ???

As to your actual question. You would either need to; attach the filter, adjust, then attach the hood or...attach filter and hood, the reach you hand in to adjust.
Another possibility is one of those rubber hoods that screw into the filter threads. I've tried this with other lenses and didnt care for it.

I've been thinking of using the trusty Dremel to cut a little window in the side of the hood.

If you do, I hope you post pictures.

Or, you can skillfully hold the lense hood in front of the lens for the shot.

I addressed that issue in my previous reply. Use a rubber lens hood that screws onto the filter and by turning the hood, you turn the filter. Cheap and effective.

I simply don't find many instances when I need to use a C-Pol on a long telephoto lens. I'm far more likely to use one on a wide angle lens.

Best solution is drop-in filters, which some big telephotos use. The C-Pol versions of these have a means of rotating the filter without having to remove it from the lens.

Or, yes, some deep telephoto hoods have ports you can slide open to access the filter to rotate it.

Another method is to substitute a generic screw-in hood (http://www.bhphotovideo.com/c/product/11178-REG/B_W_65069638_95mm_Screw_In_Metal_Telephoto.html), that threads into the filter, so that hood and filter can be rotated together as one. Not a cheap solution ($70+ for a metal 95mm tele hood?), but after spending what a quality 95mm C-Pol costs ($250 for the B+W Kaësemann), I'd want to protect both lens and filter as best possible from bumps, as well as oblique light.

If you are using theCPL for it's best effects you will be 90 degrees away from the sun so flare won't be a problem. BTW flare usually occurs when shooting into the sun, a hood or a polarizer wouldn't prevent this anyway

First if your doing wildlife why would you even want to use a CP filter on a long lens??? People spend big bucks on fast lenses for a reasons. Second, you could almost forget about AF. Third, it's going to cost you two f stops, think about it.

I see lots of comments of flare/how to use, but in my experience even trying to use a CPL on my 70-300 at airshows that the CPL blocks too much light for the autofocus to work as well as it should. I almost always end up taking it off. Now If i had a nice lens like a 400mm f/2.8 or 500mm f/4 (about half of what my car cost) I might not have a problem ").

You can shade the front of your lens with the "black foamy thing". You should have one in your bag! (Neil Van Neikerk)Check it out!

That's why you always wear a hat. Does a great job eliminating flare in such a situation and keeps your brains warm otherwise. A baseball cap with a dark under brim keeps flare minimized in your eyes too. Hat and tripod. Don't leave home without them.
