This is probably worth the cost--but not much more
on August 14, 2013
I received this Promaster white balance lens cap today and was ready to throw it away after the first hour. First--I realize that there are several very positive reviews. I used this cap with my 5D Mark II and with a 70-200mm F/2.8 IS II lens. My first attempt was to see how it would perform indoors by photographing my 91 year old mother sitting in her rocking chair with a bright light to her right. After using the Promaster 77mm White Balance Lens Cap in this setting, it was virtually impossible to obtain any usable image of her. I tried several times--went back to YouTube to see if I was using the product incorrectly--then to its own manual (which is a single page PDF from their website which is not included in the package)--and then tried several other times. The images were as cold as ice--yes--I shoot raw and can correct this in Lightroom-- but after using the cap indoors for about an hour, I simply concluded that this cap in worthless if you are shooting indoors.
Next--I took the camera and cap outside a little after 7 pm Central Standard Time here in Texas--when there is still plenty of available light--and the cap performed quite better. I came back inside--used it again in a different room photographing other subjects and under different lighting conditions--and the results were a little better than my first attempt to photograph my mom. The images were still on the cool side--and will have to be modified using Lightroom--but they were not nearly as bad as the first set of images of my mom sitting in her rocking chair.
Initially, I was going to give this product one star--but after using it in another room and outside--I decided to bump up the rating to 2 stars. I was going to be returning the product after the awful first set of results--but for the money--it's okay with the caveat that it probably will only be useful when shooting outdoors. If you shoot primarily indoors--believe me--the images will be very cool and you will be modifying your exposure in post quite a bit. Thus--if you're going to be doing that--you probably are no better off than simply using one of the presets available on your camera.
