Nikon's Newest Full Frame Fisheye Option

For starters, the Nikon 8-15mm is a stunningly sharp lens. The images I have taken are clear and have great depth and detail. It is also a very versatile lens. Although made for a full frame camera, it can be used on a crop sensor camera as well. It makes beautiful diagonal images and has the added benefit of zooming out to 180 degrees in every direction, creating a circle in the frame

Although not really a zoom lens on a full frame camera (as implied by the 8-15mm) rather, it is an 8mm circular fisheye lens and a 15mm wide angle fisheye; in effect, two lenses in one. There is a vignette from about 14mm down to 9 or 10mm that doesn't quite form a full circle, so the 'in-between' isn't really usable. But, the lens can also be used on a crop sensor camera above 10mm where it will completely cover the frame. So on a crop sensor camera, it is a 10-15mm zoom lens. Below 10mm, there is a vignette and it never reaches a full circle.
I had the opportunity to take this lens on location with me to Fiji. The sharpness and clarity of the lens can be seen in the spines of the soft corals. Although on a full frame camera I rarely shoot with an aperture under f/11, this image was shot at f/9 and is still quite clear.

For some, having a circular fisheye lens isn't a draw at all. Others will rejoice at the versatility and freedom the lens gives them. In my book, having the ability to switch between circular fisheye and a regular diagonal image while underwater is a big plus. I like to shoot circular fisheye, but I don't want to devote an entire dive to it. Only a few subjects lend themselves to circular fisheye, and I would rather have the option of zooming my lens out when the time is right, than spend spend my dive searching for that one special opportunity.

The circular fisheye leaves a darker blue ring around the image which can't be helped, but can be adjusted in post.

I found another perk in the form of available dome ports for the Nikon 8-15mm. The tiny Zen 100mm lens with removable hood works great with this lens on a full frame housing. It wasn't a good fit with the Sigma 15mm so I had to use a large dome port to accommodate that lens. Now I have the option of getting really close and in tight for close focus wide angle shots with this lens and port combo. The hood removes easily which makes it a great option for circular fisheye as well. 

In my opinion, the Nikon 8-15mm lens is much better than the Sigma 15mm and the Tokina 10-17mm. For those who shoot with both full frame and crop sensor cameras, it can replace both lenses in addition to the Sigma 8mm fisheye lens. This makes it a valuable tool and a great buy, replacing three lenses with just one. Have a look at the following images and judge for yourself, but I will definitely keep the Nikon 8-15mm lens in my camera bag.
