Its not an amazing lens, but a fun one none the less
Allowing instant shooting, the 15mm lens is great for when you need to take that split second shot during the day.
Designed as a lens that substitutes for a body cap, the new 15mm f8.0 Body Cap Lens features a 3 element in 3 group wide-angle design. A small lever enables manual focus and it has an infinity setting as well. Designed to accentuate the effects of Art Filters, the fixed aperture optical design creates sharply focused centre regions with softer edge details.
I don't see why you would want to replace your body cap with a lens that isn't even that great. You might as well just keep a standard prime on it then.
