With A View up to 180 Degrees

The fisheye lens is an interesting accessory. I have one that zooms from 8mm to 15mm. At 8mm the lens can take in a full 180 degree view. At 15mm it has a 175 degree view.

At the 8mm setting my lens produces a circular image and at 15mm the image is full frame. Regardless of the zoom setting the images are distorted and produce a panoramic effect. You can often recognize one of these images by seeing that straight lines appear curved.

I’ve used this lens both in the field and in the studio and get a kick out of some of the fascinating results.
 
 

Wide Angle to the Extreme

It’s eye-catching when I see a photo that “bends” the horizon.

This bend comes from the camera’s lens. Use a very wide angle lens and you’ll see the curved “barrel” distortion on the images. One well-known type of wide angle lenses is the fisheye. These lenses typically have a field of view approaching 180 degrees – allowing you to capture the entire scene in front of the camera.

Until recently, fisheye lenses were expensive. I have one that cost well over $1500. But when I was looking for an ultra-wide angle for my Sony equipment, I found an inexpensive lens made by Rokinon. With its $300 price tag, I was a little skeptical of the quality of images from such a low cost lens but decided to try it regardless.

Here’s a short gallery of some of the scenes that I captured during my first outing with the lens a few weeks ago.
 
 

This is an 8mm f/2.8 fisheye. I wanted an ultra-wide angle for an extra Sony Nex7 mirrorless camera.	The Nex7 is very compact and lightweight. The Rokinon 8mm fisheye is also surprisingly compact.
The Sony Nex7/Rokinon 8mm setup is only about 1/3 the size of my Canon 6D with a Canon 8-15mm fisheye – a true space and weight saver.	One of the first images that I recorded with the new lens was in the Tetons. I especially like the curved horizon.
Here in Yellowstone you can see that the bridge rail curves upwards. The lens does not support the camera’s autofocus feature.	However an 8mm lens has a very wide depth of field which makes focusing less critical as you can see in this image taken at Mono Lake.
At Grand Canyon, the bend in the horizon is amazingly scenic. The lens does not support autoexposure so I set the camera shooting mode to manual, set the lens aperture to f/8 and adjusted to the proper shutter speed.	In both of these photos, you can see that the exposure for both a shaded and sunny scene were correct. Neither the manual focus nor the manual exposure requirements of this lens is a concern.
At Monument Valley I took advantage of the lens’ extreme wide view. Here I was able to take in a 180-degree view to photograph this huge monument within a single image.	The fisheye excels for those of you who like shooting portraits that include the vast surroundings.
At Mesa Verde, we encountered another “tight squeeze”. However, we were able to capture this with the lens’ wide view.	In Rocky Mountain National Park, the lens took in not only the winter’s left over snow but the billowing overhead July clouds.
What about the sharpness? Here I’ve enlarged a small section of one of the above images. You can clearly see the detail in the face, the lettering of the cap and the tufa formations in the background. I found the sharpness of this inexpensive lens to be very acceptable.

After my short time with this lens, I am no longer skeptical of it’s quality. The images are tack sharp with very good color reproduction. If you’re on the lookout for an ultra-wide, include this lens in your search.

The Rokinon 8mm f/2.8 fisheye is also available for other camera models as well: Fuji, Samsung and Canon M mount. Other similar versions with a maximum f/3.5 aperture are available for Canon, Nikon, Sony A mount, Pentax and Olympus 4/3.

Photographically speaking, a panorama is a photograph that encompasses a very wide view. I like panoramas because they reproduce a scene as if I were viewing it live by turning my head from the far left to the far right. I can view the photograph in small ‘chunks’ as I scan the entire image from the left to the right.

In the past, making a panorama was a complicated, multiple step process involving capturing the images and then stitching them together whether it be done chemically in a darkroom or digitally with a computer. I won’t go into details of making panoramas using either of these two “conventional” ways. Instead, I’ll point out the ease with which a feature on certain cameras enables me to easily make panoramas in one step.

For the past two years I’ve been using several Sony Alpha series and NEX series cameras to shoot panoramas. These cameras enjoy a feature called Sweep Panorama. When this feature is chosen, you simultaneously depress the shutter and move the camera in a sweeping fashion to the right. As you do this, the camera captures multiple images of the scene. The camera signals the completion of the sweep by halting the shutter. A few seconds afterward, the panoramic capture appears on the camera’s LCD for your review. Press the PLAY button and the image is displayed from left to right – in video fashion – but is actually a single, still panoramic image.

Above, I explained that the sweeping motion is from left to right. But in fact these Sony cameras let you sweep left to right; right to left; up to down; and down to up. These cameras also capture three dimensional appearing images using 3D Sweep Panorama that can be displayed on certain compatible 3D television sets.

Here’s a few of the panoramas that I’ve taken with various Sony cameras. You can click on each of the images to see a wide view of the panorama.
