This 55mm Hoya RA56 Green Enhancer Filter 55mmfrom Hoya RA56 Green Enhancer Filter 55mmis designed to enhance colors in the green spectrum without changing or having negative effects on other colors. Combining the Green Enhancer with a circular polarizer or a UV filter will also increase the saturation of the color and the sharpness of an image, such as foliage in a landscape shot.

The glass filter has a filter factor of 2.5, so you should increase your exposure by 1 and 1/3 of a stop to compensate. Transmission of light passes easier through the filter because of a single type of coating, which has been placed on both sides of the glass, reducing reflections off the surface of the filter. The ring is made of aluminum, adding strength and protection to the lens while it is screwed on.

Q: 1. I'm looking for the Hoya Enhancing (Intensifier) Glass Filter, wanting to use mainly in lens 18-55 (52 mm), but also would like to use on my 50 mm f/1.8 g, then I'd buy the 58 mm filter and adapter https://a href= http://www.bhphotovideo.com/c/product/1068079-REG/sensei_surpa_5258_pro_52_58mm_aluminum_step_up.html target= _blank www.bhphotovideo.com/c/product/1068079-REG/sensei_surpa_5258_pro_52_58mm_aluminum_step_up.html/a for use on the 18-55.I need to know if that would cause any vignetting in 18-55 18 mm.Thanks!?

A: Hi Igor!I use the 58mm filter on a few different lenses, including a 24 with a 52mm adapter. Since you are going from smaller to larger you should have no issue. If you were to try to use a 52mm filter on a 58mm 18-55 then you may have an issue because you're down sizing. Since you're pushing it up in size there should be no issue. Hope the filter works well for you!

Q: 4. I have a Nikon lense which takes the 52mm size screw in filters. the lense is a 55mm. so I am looking at 52mm filters and step up rings. the question is, are the threads on this ring compatible with the rings on my Nikon? are thread sizes the same brand to brand? is it universal like mini usb charging adaptors for cell phones. since Nikon doesn't make many filters etc for its lenses I keep seeing all these from different brands and am curious if they are compatible. my lense is 18-55mm and I would love to enhance fall colours. thank you.

A: Filter threads are standard. If you have a 55mm lens, you need to get a larger filter size, and use a step up ring from your lens to the filter. If you use a smaller 52mm filter on a 55mm lens, you will have a large round black border around your entire picture because of the vignetting.

Also, all composition must be done prior to putting the filter on the lens as you will not be able to see once it is in place.
