This is a seamount adapter that I made for my Nikon J1 and I'm going to test it with a couple of these seamount lenses and compare it to the kit lens for video. This lens is a 50 millimeter F1.4 lens and this other lens is a TV zoom 17 to 102 millimeter F2.0. This is the kit lens 10 millimeter to 30 millimeter with everything in fully automatic mode. This is the 50 millimeter seamount lens with a wide open aperture 1.4. It's worth noting that the automatic ISO does not work when a lens is not detected. So you'll have to do all your exposure adjusting by changing the shutter speed or the aperture on the lens. This is the TV zoom lens and you can see a lot of camera of the camera. This is a very good lens. This is a very good lens because my adapter is not completely solid and with this big heavy lens it tends to wiggle around a little when I'm trying to make adjustments. I think this setup would be fairly solid if I made an adapter to mount the lens directly to the tripod instead of relying on the adapter mount to hold this heavy lens. This is the main reason I made the adapter. It's much easier to get a good high-speed shot with the fast seamout lenses. The 50 millimeter seamout is on top and the kit lens is on the bottom. You
