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.

My 6300-Mile Field Test

On our recent vacation, my camera of choice was Sony’s newest mirrorless camera. While I also brought a much larger Nikon D700 conventional DSLR, I relied mostly on the the Sony A6000. As a comparison, I captured about 150 images with the Nikon D700 and more than a thousand images with the Sony A6000.

My setup was the A6000 coupled with Sony’s 18-200mm lens. This combination is lightweight and compact, produces quality images and just happens to fit beneath the driver’s seat for fast, convenient access.

Hopefully, the following photographic sampler illustrates the A6000’s versatility. I’ll add a few techie details afterwards.

The A6000 is smaller than a conventional DSLR so it’s both lighter and more compact.	You can compare the sizes of the A6000 next to the conventional Nikon D700 DSLR.
The A6000’s high resolution 24MP sensor renders scenics with very high detail.	Additionally, the camera can capture subjects that have a wide range of exposure levels.
The A6000’s articulated LCD makes it easy to capture stills and closeups.	The much improved focusing system works well for wildlife shots.
With the 18-200mm lens, I can keep dry while still in on the action.	Here’s some quick, responsive focusing
The A6000’s bright viewfinder makes it easy to compose and frame in bright sunlight.	The electronic viewfinder previews the scene with the camera adjustments applied.
It handles action shots well and can capture up to 11 frames per second.	The exposure system works quite well with a wide variety of subjects.
I used the camera’s sweep panorama feature often to automatically produce some very pleasing large images.

I suppose it doesn’t matter than I traveled 6300 miles with the camera other than I used it under a variety of conditions.

My “film” was a 32GB SD card, but I never filled it with the 200 pictures a day (the camera was set to record simultaneous RAW and JPG images). All in all, I’m very happy with the images that the camera produced. The one small gotcha is that the A6000 has a short battery life – probably due to the electronic viewfinder. Thankfully, I had an extra battery that I carried along.

Since this is my third Sony mirrorless camera, you can safely assume that I’d recommend this camera to others. In fact my daughter must have agreed with my assessment and purchased one.

For those interested, here’s a few of the technical specs for the A6000:

Sony A6000 os a mirrorless with a 24MP sensor. One of the reasons for choosing this camera is its fast and accurate hybrid focusing system that allows up to 11 frames per second capture. Other proven features are its “sweep panorama”, automated HDR capture, easy exposure bracketing, and Sony’s proven video recording.

List price for the A6000 body without lens is $650. The 18-200mm lens cost $850, more than the body but this single lens allowed me to enjoy the scenery without clutter of additional lenses.
