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 😉

Tuesday (19-February-2013) — Trans-Atlantic Flight

Gone to See Norway 2013 Chasing the Northern Lights. Day 22: Bergen – Copenhagen – Newark Flight Home.

While on the Copenhagen to Newark leg of the flight home we crossed Greenland. Someday I want to visit Greenland.

Gone to See Norway 2013. Chasing the Northern Lights. Day 16: Tromsø.

I spent the day putting together a time-lapse video for one of the Northern Lights displays. Still many more to go. I catch the southbound Hurtigruten at midnight for a ride back to Bergen.

Gone to See Norway 2013. Chasing the Northern Lights. Day 15: Tromsø.

For my second night of chasing Aurora I went with “Northern Lights with Green Fox Guiding- When The Sky Becomes Magic”. Green Fox Guiding is a relatively new company, but Jacek Orasinski has been working in the Tromsø area as a guide for the last 11 years. Jacek is originally from Poland. The group was picked up in front of the Tromsø Tourist Information center at 17:00 (5 PM). There was low fog covering Tromsø. Jacek was pretty sure that as soon as we got away from the city we would have some clear skies. The Space Weather report was also favorable for the appearance of auroras during the night. A little after 18:30 we had our first sighting. This was one of the earliest displays that Jacek had seen this season. We stopped along the side of the road and got some initial images. Jacek drove us a little further to a better location with mountains in the background. Even though there was just barely a sliver of the moon, a couple of Norwegians were climbing the mountain. While photographing the Northern Lights we watched these two tiny lights climb up the mountain and then ski down in the dark. Once down, they started up the mountain again. Jacek knew that I was looking for something unique to use as a background. He brought us to an abandoned coal mine which I thought was great. I think the others got board after a few minutes at the site. I framed an image of the Northern Lights display with the silhouette of a coal chute in the foreground. As I was taking the 30 second exposure, a tour bus drove by and lit up the coal chute. I wasn’t planning on doing light painting – but as can be seen below I am happy with the result. We continued on to several other locations, with the Northern Light displays getting better and better. Finally, we ended up on a beach where we continued shooting. Jacek built a wood fire to heat his signature “Fish Soup”. We were provided with reindeer skins to sit on as we ate the soup. After dinner the Northern Light displays continued for another 3 hours. Although I thought last night was great, this was an order of magnitude better. Jacek even said it was the best night he had seed this season. In all, I took about 1400 images. Many, many will be used for time-lapse videos. I didn’t get back to the hotel until 02:00 and then couldn’t sleep as I wanted to start reviewing the images.
