The filter goes into the slot in the holder closest to the lens. You can then use the toothed edge to rotate the filter, just as you used to turn your old polarizing filter. It can be a little stiff, but it will turn.
Your FZ45 accepts 52mm filters. You can use any 52mm filters you wish on this lens.
There are two types of polarizing filters: linear and circular. The linear polarizing filters are for film cameras and *some* digital cameras. Circular polarizing filters are needed by many digital cameras because the linear polarizing filter types interfere with the autofocus programs. If you shoot in manual focus modes only, it won't matter which you buy. If you do use autofocus, you ought to try the linear before buying - otherwise, purchase the circular polarizer.
I hope this helps! If it did, please rate my reply "4 thumbs up". Thanks!
it is most likely a burned polarizing filter. There is a polarizing filter on the blue light channel and another on the red channel. When black, or other dark colours are displayed, the red polarizing filter is supposed to block ALL of the red light being projecter. If the filter is burned, some light slips through and creates a red tinge on the projected image. If the red tinge only appears on dark images, but is absent when the images is completely white, a damaged filter is likely the problem.
Seems its hard to buy them. Best bet is probably buying a broken projector from ebay and stealing the filters out of it.
First of all, yes, the filters work for both film and digital cameras. Both amazon.com and bhphoto.com are good sources for filters. A good polarizing filter is Sunpack...good price, great value.
Hi,
Based on the fundamentals of retaining rings, The filter lens probably fits into the ring housing first, and the retainer ring is inserted inside of the ring, following the lens. The retainer will need to be compressed in order to fit inside the ring, but will snap into a groove once in proper position.
I hope this is helpful... Good luck.
No, the problem is not with the lens. Your Canon camera requires unpolarized light to focus. Even on manual focus, you may have trouble seeing focus through the viewfinder. That's why they invented circular polarizer.
