Improve the consistency of your DSLR camera's color photos with this ExpoDisc 2.0 EXPOD2-77 77mm lens filter, which lets you set white balance, meter 18% incident exposure and dust map your camera's sensor to ensure images with a high level of quality.
The expodisc 77mm is perfect for my 50mm lens. If I used and bigger lens I might run into it not fitting but as far as it goes it works perfect. My pictures are fast easy and fun! So glad I purchased this
