I just bought a new Canon IS 10x42L. While the images are clear and crisp it does show yellow color on the edge of a subject especially when the subject is contrasted against a blue (like a bird for example) or black sky (Example, watching the moon at night shows a yellow edge on the left end side of the moon, no coloration around the terminator though). Yellow edge on subjcets will diminish when moving the binoculars a little and only shows up when holding the camera still for a few seconds. Engaging the IS makes it worse. What can I do?
