Hoya 52mm HMC Red 25A Screw-in Filter

Beautiful filter...in most excellent condition! Arrived packaged very securely and on time. This item is as described in the listing, and I amvery pleased with it. A great addition to my photographic arsenal. Thanks very much.

I use this filter on a monochrome digital camera and it makes skies more dramatic by darkening the blue regions without affecting the white clouds. Here are some photos I took using it on my Pentax K3III Monochrome at Trona Pinnacles near Death Valley

Excellent quality yellow glass filter. No vignetting.

Excellent filter for darkening the skies when shooting (or converting) your photographs to black & white. You could just adjust your settings to approximate this filter in PS, but there is something to be said for doing it the traditional way.

Super well manufactured, glass is immaculately smooth and red is uniform the whole way through - but be advised this won't simply add red to your shot, when you check your histogram, you'll see nothing but red.

the filter works great! good contrast, blacks are really black when you shoot in black and white. It does it job well! great buy.....

I used this for B&W photography. Works as expected.

Awesome filter. High quality. Will be purchasing more in other colors.
