Gear for the chase
When I first hiked the John Muir Trail, I actually wondered whether there would be great photo opportunities. We would only go past the backside of Half Dome. Likewise the Mount Whitney Crest. No icons at all to photograph. It is true that the mountain scenery on that trip is gorgeous, but daytime photos of it generally are not. It was on this trip that I learned to chase the light and some of the rules of the road for doing so.
On any hike in the backcountry, it is essential to be open to the sights of the day. Unexpected opportunities appear and disappear. Reacting quickly can make the difference between a great shot and an ordinary one. It is true that many photographers head out with a pack full of lenses, an extra body, and a tripod. They must be Navy Seals.
For me that doesn’t work, and it especially doesn’t work on a 30 day hike, most of which is above 10,000 feet. On a hike you might be unable to stop and wait for a hour or more for the light to be right. After a 3,000 foot ascent, you may be very tired when an opportunity presents itself. It is essential to be open to the unexpected and to be able to move quickly to capture the image the moment it presents itself.
Galen Rowell, in my mind the father of contemporary adventure photography, used a 35mm file camera, at a time when many “serious” photographers insisted in medium or even large format cameras for photography. The modern version of that camera is a lightweight mirrorless digital camera.
At first, I used Nikon or Canon APC cameras because they were the lightest available. Some of the photos from these cameras are presented on this site. The lenses available for these cameras were good, but I was looking for better quality.
In 2012 Olympus came out with the OMD, a small, lightweight mirrorless camera. Olympus has traditionally been a source of excellent lenses. I loved the mirrorless feature and the reduced weight because of it. Despite some loss in visual quality through the viewfinder, the fact that no mirror had to be moved during exposure meant for very smooth shutter operation, especially important at low light situations.
I have never looked back. Now I have the newly released OM-1. It is an adventure photographer’s dream camera. The body is quite light. It is the world leader for in-body-image-stabilization. Crisp clear hand-held shots can be had from shutter speeds of a couple of seconds or more. It has focus tracking that will follow a bird, for example, and capture full resolution images at 50 frames per second. It has in-camera high dynamic range capability that is cleaner than ever thanks to a faster sensor. The same sensor speed has also improved the image quality of the in-camera focus stacking. It provides a hand-held 50 megapixel option for relatively still subjects.
The camera also has a new feature that simulates a neutral density filter enabling clear shots of flowers aside a blurred stream. Each of these features can be programed to a single button or dial for immediate access.
It has best-in-industry weather proofing. I will stop this list with a mention of the 5.76 dot OLED electronic viewfinder, which for all practical purposes is as good as optical.
Putting aside for the moment the hand-held 50 MP feature, the big issue with the camera is its 4/3 sensor, which is half the size of full frame cameras. It also has “only” 20 megapixels. There is no question at all that on a bench test, there will be greater detail from a 40 to 50 MP full frame sensor. Likewise there is no question that the full frame camera, and especially its lenses, will be much, much heavier.
Operating in the field is quite a different matter than conducting a bench test. The equipment must be carried, sometimes for great distances over difficult terrain. My OM-1 with a Pro f4, 12-45 lens weighs less than 2 pounds including battery. No full frame body with a pro quality lens comes close. God forbid that a tripod would be needed. That weight not only has to be carried, but it has to be hefted into place for a steady shot in the low light conditions that prevail at dawn, dusk or after a storm.
Let’s look at a typical example. Start with a camera setting at f4, ISO 200, and shutter speed 1/100. As the light dims, the Olympus camera with its unbeatable stabilization allows you to maintain the 200 ISO setting while decreasing the shutter speed. If the light drops 8 stops, the shutter speed can be decreased to 4 seconds. With care you can get a great, clean shot of stationary subject.
A full frame camera and its much heavier lens is at a severe disadvantage. It is a challenge to hold that rig steady for a shot at 1 or 2 seconds shutter speed, much less 4. Instead, it is more likely that the photographer will have to increase the ISO. If the ISO is increased by the same 8 stops to 12,500, the photographer can get the shot at 1/100 shutter speed, but at a noticeable loss of image quality.
For action shots like wildlife, no competitor, full frame or otherwise, can deliver full resolution focus tracking at 50 frames per second. The lighter weight of the Olympus is also a tremendous advantage when moving quickly to keep the camera framed on the darting unexpected movements of wildlife.
For some reason, I wish the sensor had more than 20 megapixels; but I can’t really figure out why. Yes, there is a limitation on the size of print enlargements, but that has no practical effect on me and probably not on many others. I have a 16 x 20 print of my Alpamayo shot on the South America page which has no discernible quality loss.
I photographed a falcon on the roof of an old office building in downtown San Francisco that was the site of Sam Spade’s office in the film noir classic, The Maltese Falcon. (It was taken with an OMD that had a 16 megapixel sensor. See below.) The Natural Resources Defense Council, which has offices in the building, made a 24 x 20 print of that shot which it displayed in a conference room. Again there was no visible loss of image quality.
However, let’s say you want to go larger. With Adobe Super Resolution, the file size can be upscaled to twice the size. My 20 megapixel image becomes an 80 megapixel image. The native raw file size for this camera is about 11 x 14. With Adobe Super Resolution, the base file size is about 22 x 28. I believe that file could be enlarged to 30 x 40 while retaining excellent image quality. I used Adobe Super Resolution to upscale my picture of the Tengboche Monastery on the Himalaya Page to a 28 x 14 print. It looks fabulous.
While I don’t want to understate the importance of technical quality, it is also a mistake to overemphasize its role. A good photograph also depends of the selection and framing of the subject and the timing of the shot. I love to hike, and photography enhances the hiking experience. It makes me think more about my surroundings, and it leaves me with images that enrich my memories. For me, Olympus lightweight, high quality equipment is the secret sauce.
