I'm looking for suggestions of how to remove a circular polarizer in the field. The problem stems around the fact that the threads get tight when it is attached to the lens then on removal the adjustment ring freewheels and makes unscrewing damn near impossible!

the easiest way is to use a leader straightener. You can find one in the Orvis catalog. Another fly fishing tip. Rub the threads of the filter with the oil from the side of your nose. Apply it with your finger. Fly fishermen rub the male furrel on their fly rods on the side of their nose to keep it from sticking.

Why not just carry a filter wrench, very cheap and small. Adorama for less than $5. They come in different sizes.

Didn't know there was such a thing. Thanks, I will look into it. Dr.C

May be wrong thread pitch. Some of the most common sizes have multiple pitches. A silicon coated Q-Tip on the threads will work as well. What size filter are you using?

Macifej: 67mm hoya for the kit lens and 77mm for 70-200f2.8. Threads are ok the adjustment ring of the polarizer is knurled to be turned while the attaching surface is smooth and of a smaller diameter that is really hard to get hold of since it is very close to the attaching part. Thanks for your input. Dr.C. Just got back from Dar and Tz hunt, believe me the Indian ocean, a few clouds, some flowers etc look really good through a polarizer!

Doc! What kind of glass might you be attaching that 67mm to?

Canon 17-85IS. Lens has generally poor reviews but takes excellent pictures? Dr.C

I have some New In Box Schneider (Schott Glass)B+W MRC2 filters in 67mm I bought in Europe last fall that I don't have a lens for. These are the absolute top of the line filters made in the world. If you want them I would part with them for a reasonable price. No clue how much they are now with the exchange rates.

I really do not understand filters and their usage enough to pop off about yours. Thanks for the offer. Dr.C

No worries! A basic understanding of the use of filters can greatly improve the quality of your images. Grab an inexpensive book and give it a whirl. Stay away from the cheap-o filters. Most are crap.

I understand B+W are the top-of-the-line. Dr.C

I'm gonna have to get one of these.
Filter Wrench

Been frustrated the same way with polarizer filters myself.

Hoya are good, too. The best ones are always expensive, so a top of the line CP for digital cameras could easily reach over $200.00.
