Backyard Spring Night Sky in New Jersey. Wide Angle Lens Options for Nikon 1 Cameras.

One of the issues I have had with the Nikon 1 “mirrorless” cameras is the lack of wide-angle lens options. The widest angle available with the initial set of lenses was 10 mm f/2.8 prime. This has a 77° field of view (FOV) equivalent to a 27 mm lens on a full-frame (FX) DSLR camera. I like taking wide-angle panorama landscape images when traveling. In order to do this with the Nikon 1 camera requires taking several images and then stitching them together during post-processing. Before going to Norway, I saw a note on the internet that the Olympus FCON-T01 Fisheye converter uses the same 40.5 mm thread that the Nikon 1 10 mm f/2.8 lens uses. The 0.74x adapter increases the FOV to something like 20 mm on a FX DSLR camera. I took this combo with me to Norway, and published an image of Greenland from 36,000 feet using the combo. (19-February-2013).

Since returning from Norway, Nikon released a new wide-angle telephoto lens for Nikon 1 cameras – the 6.7 – 13 mm f/3.5-5.6. At 6.7 mm this lens has a 100° FOV equivalent to a 18 mm lens on a FX DSLR camera. The following three images were taken with the Nikon 1 V2 camera 1) with the 10 mm f/2.8 lens; 2) with the 10 mm f/2.8 lens and the Olympus fish-eye converter; and 3) with the 6.7-13 mm lens at 6.7 mm. The wide-angle image with the 6.7 mm does not have the fish-eye curvature effect. Indeed, when in Norway I found that when I used the Olympus lens I would need to keep the horizon right at the middle of the image. I think that I will be adding the 6.7-13 mm lens to my light-weight travel kit.

Note: Nikon changed the threading on the 6.7-13 mm lens to 52 mm, so I can’t use the Olympus adapter with this lens 😉

Backyard Late Autumn Early Morning Sky: Last Quarter Moon.

It has been a long, but mainly productive day. I got up very early to get a picture of the last quarter moon. I wanted to try out photography of the moon through a 500 mm telephoto lens using the Nikon 1 V1 camera. Because of the smaller size of the image sensor vs. a 35 mm (FX in the Nikon digital world) the effective field of view with this setup is equivalent to using a 35 mm camera with a 1350 mm lens (~2.7x). Since the N1V1 camera does not have a mirror (the mirror in a DSLR needs to move out-of-the-way when taking pictures) and has an electronic shutter mode — there is no mirror slap or shutter motion when taking pictures. This is important when taking pictures through large telephoto lenses where any motion or vibration will blur the image. I had hopes that this would help to get a sharp image of the moon. One limitation with the N1V1 with the FT1 adapter is that it can only autofocus through the center autofocus sensor. For this image I manually focused the lens (and set the camera to manual focus so it would not try to autofocus before releasing the electronic shutter). I used the remote (IR) shutter release so I would not be adding additional vibration to the system. I was impressed with the result. I did take several images trying different settings, and this was one of the better ones.
