This is an excellent finder. At all settings the image was clear and bright and being able to see outside the frame was helpful in composing the photograph. I found the 50mm setting, due to the position of the finder on the camera, vital in properly composing a photo with my Jupiter-8. The cleverly designed plastic case will keep your finder safe when you're not using it. All in all, this is a necessity with any lens, even a 50mm!
