Long Lens Tips And Techniques
My first long lens, purchased back in 1983, was the Canon 400mm ƒ/4.5 FD. I worked with that lens for seven years, not fully realizing the incredible benefits of the really big glass until some guy let me look through his 600mm ƒ/4 Nikkor lens on Sanibel Island…. Soon after, I jumped all the way up to the old Canon 800mm ƒ/5.6 FD and entered the world of huge magnification. Since the advent of autofocus, I’ve owned and used several Canon EF 500mm and 600mm ƒ/4 lenses. Today, I’ve come full circle—my favorite big lens right now is the EF 800mm ƒ/5.6L IS. That said, I’m looking forward to the availability of Canon’s two new big guns, the EF 500mm and 600mm ƒ/4L IS II supertelephotos.
Over the years, I’ve reviewed, sold and, most importantly, enjoyed more than a few images that were created with long lenses and teleconverters. In this article, I’ll share many of the techniques that I’ve used and developed over the past two-plus decades.
1) Big Glass And Teleconverters Lens Correction
Many folks who invest in big glass shy away from using teleconverters. Doing so is a huge mistake as they’re forfeiting focal-length flexibility and extra magnification, which provides more pixels on the subject. By practicing your sharpness techniques—try supporting the lens with your left hand from below rather than above—making sharp images with the 2x TCs and either the 300mm or 400mm ƒ/2.8 lenses should be child’s play at most reasonable shutter speeds. And I’ve long believed that competent photographers should be able to create sharp images with a 2x TC and a 500mm or 600mm ƒ/4 lens down to 1⁄60 sec., as long as the subject isn’t moving. And that goes double with the sharper optics and the improved image stabilization and vibration-reduction systems of newer lenses.

2) The Sharp, Fast, Versatile 300mm ƒ/2.8
For years I had my eyes and my mind closed to the 300mm ƒ/2.8 lenses. That all changed when I borrowed one for my big Antarctica trip with Cheesemans’ Ecology Safaris in early 2012. I loved it so much that I extended the loan and brought it along to Japan for a month. On the Southern Oceans trip, I needed to travel light; the Canon 300mm ƒ/2.8L IS lens was my big lens. It was great in the Zodiacs® and great for handheld birds-in-flight photography with or without the 1.4x TC. I used it with the 1.4x TC for all of my sea eagle flight photography in Hokkaido, and it was great for the snow monkeys as well. Aside from the light-gathering ƒ/2.8 speed, the lens is mind-bogglingly sharp.

3) How To Recognize Good Situations
Telephoto lenses offer a narrow angle of view, a bit more than 3º with the 800mm lens on a full-frame camera and well less with crop-factor bodies and/or teleconverters. Many folks don’t realize that if you wish to create images that feature clean backgrounds, working with a narrow angle of view is much more important than working at the wide-open aperture. The farther the background from your subject, the softer the background will be. Learn to look for great situations where your long lens can provide clean backgrounds. Nearly all of the gannets at Bonaventure, Québec, nest on the ground. When I came upon a pair building a nest atop a viewing shelter, I stayed with them for several hours.

4) A Tripod Is A Necessity!
Working off a sturdy tripod with long focal lengths will—almost without exception—pay huge dividends in terms of image sharpness. For years, I’ve used and depended on the sturdy and rugged Gitzo GT3530LS 6X carbon-fiber tripod. When using the 800mm ƒ/5.6L IS lens with the Canon 1.4x III teleconverter or the 300mm ƒ/2.8L IS II with the 2x II teleconverter as for the Macaroni penguin image, you’ll always find my long lenses on a tripod. When working with relatively static subjects, snugging up the knobs on your tripod head will help you produce even sharper images.

One of Arthur Morris’ skilled students, Clemens van der Werf, shows good technique. He’s supporting the lens from below with his left hand, and his face is pressed firmly against the back of the camera. This is much more reliable than holding the lens on top and trying to keep it steady with downward pressure. With these long lenses, even the slightest movement results in softness in the image, so proper technique is mandatory.
5) Rear Focus And Recompose
When using teleconverters with certain long lenses, you’re often limited to the central autofocus sensor as I was here with the 800mm ƒ/5.6 with the 1.4x III TC/EOS-1D Mark IV combination. I set up all of my camera bodies to remove AF from the shutter button; I use the star button to focus. For this image, I focused on the chick’s eye by pressing and then releasing the star button. Then I recomposed by pointing the lens to the right to place the bird pleasingly back in the frame. For flight photography, just push and hold the star button to track the subject. Also note that I’ve pointed my shadow right at the bird; doing so and getting low ensured pleasing results in the relatively harsh midafternoon light.

6) Big Lenses And Gimbal Heads
It took me years to learn this lesson: Using a gimbal head makes lens handling easy and efficient; any telephoto lens will be rendered weightless (be sure to balance your rig whenever mounting the lens or adding or removing accessories). I used a Wimberley head for years, and many folks still prefer them for their bottom-mounting system—the lens plate is parallel to the ground. I went to the 4th Generation Designs Mongoose head years ago to save weight. I love the side-mounting M-3.6; the lens plate is perpendicular to the ground. If you can comfortably support your rig in your right hand for 10 full seconds while mounting, you’d surely enjoy the substantial savings in weight; the M-3.6 weighs only 26 ounces. Despite its light weight, I’ve had no problem making sharp images with my 800mm lens at shutter speeds as slow as 1⁄6 sec.

7) Wildlife Shown Small In The Frame
Long focal lengths can be used to extract dramatic areas of interest from the grand scene and create images that effectively include small-in-the-frame birds or wildlife. I used my 800mm lens here to frame these distant sandhill cranes during fire-in-the-mist conditions in New Mexico, with the ground fog lit from behind by the rising sun. Remember that it isn’t always necessary to fill the frame with your subjects to create powerful images.

8) Handholding For Flight
There’s a small, but growing army of folks led by my colleague Jim Neiger who find that handholding supertelephoto lenses for flight and for action enables them to capture high-quality images consistently. Strength and stamina are big factors, of course. If you try it, make sure to get your left hand well out on the lens barrel; you wouldn’t try to hold a log by one end, would you? Don’t attempt to hold the lens up in the ready position all the time. Instead, hold it at your side or find something to rest it on before raising it when the action develops. I had made a series of sharp images of this osprey while handholding my 800mm until fatigue got to me. This photo was created moments later with the lens on the tripod.

9) Long Lens AF Tips
Learning and practicing the intricacies of your camera’s autofocus system can help immeasurably in your efforts to create dramatic imagery. I recommend that you use rear focus 100% of the time. Done properly, you’ll be in AI Servo or C and never have to switch to One-Shot or S ever again. Learn to manually select off-center AF points. Learn the advantages and disadvantages of the various AF options and arrays. When working with relatively distant subjects, make sure to set the limit range switch to far, especially for flight photography. And remember that prefocusing manually (if your system permits) will make for faster initial focus acquisition (especially when it’s snowing!). For this red-crowned crane image, I made sure to prefocus manually and used central sensor/expand to 45 points.

10) Your Vehicle As A Blind
There are countless situations where working from a vehicle can get you a lot closer to wildlife than if you were on foot. This is especially true at wildlife refuges that have auto tour routes. Approach very slowly, and be sure to kill the engine before making any images unless you’re at a fairly high shutter speed and suspect that your subject is extraordinarily nervous. I use a large beanbag called a BLUBB (Big Lens Ultimate Beanbag) that I designed myself to ensure making razor-sharp images when working from my SUV. It’s available from the BIRDS AS ART online store at store.birdsasart.com/shop/.
