Long Lens Technique

Last night at the RMC faculty art show gallery opening I was asked "how on earth do you always get such sharp results?" My short answer was "very carefully;" but in the long answer long lens technique became the topic of conversation. A while ago I shared my thoughts on a long lens support. If you look through my gear list you see that I have long lenses and by looking at my photographs of wild animals you will see that I use those long lenses often.

Good or proper long lens technique is not my creation, nor is it something that I will claim to be the master of; but a devote practitioner... yes. Through my upbringing in competitive archery and photography I have spent 20+ years of my life concentrating on being able to hold still. When I speak of long lens technique I am focused on using long lenses while mounted on a tripod and suitable head (gimbal, ball, or fluid). If you are not using a tripod you should buy a good one, that alone will make a huge improvement in the quality of your images, then you can start to worry about long lens technique.

I demand absolute sharpness from my images, each image that I keep can be shown at 1:1 and still prove itself to be critically sharp. I have honed my approach on long lens technique to deliver the results I demand as often as possible.
  • Use a tripod and head that is designed to stabilize the equipment you are using. The $75 special at Best Buy is not the right tripod to do the job.

  • If you are using a lens that is physically long consider using some form of long lens support.

  • Place you left hand on top of the lens, roughly over the center of the tripod. Your left hand should be resting gently, not applying any real force, as it is simply in place to absorb vibrations as they travel through the system. (I do not recommend using a bean bag in place of your hand)

  • Grip the camera securely in your right hand; but you do not need to put it in a death grip. (Your right hand becomes another contact point to absorb vibrations)

  • Press your shooting eye firmly against the cameras eyecup. I personally use a larger more comfortable eyecup on my Canon 7D, as it is the camera I use most often with my long lenses. (Your eye and face become another contact point to absorb vibrations)

  • Calm your breathing, relax, and focus. This should also help to slow your heart rate, especially when those incredible and exciting situations arise.

  • Keep your finger on the shutter release, and simply roll your finger to trigger the camera. If your finger is floating over the shutter release you will likely hit or poke at the shutter release causing vibrations, and potentially a shift in your framing. (Just like squeezing the trigger when shooting a gun or bow)

  • Get out there and practice, use your camera in this manner often (ideally I would say daily). The biggest reason I know my camera, lenses, and other equipment so well is because I take several thousand photographs each month. If you don't have "good" local shooting just get out and shoot something, think about it like you would going out to exercise to stay in shape; but call it camera shape.
Some other things to consider:
  • Be sure to dress for the conditions. If you are cold and shivering your photographs will show it.

  • Be sure your tripod is the right height for you. If you are standing be sure you can stand tall. If you are sitting be sure you can sit comfortably. (If you are not comfortable and balanced you will not be able to fully control your camera)

  • Relax, I believe that most everything in life is at its best when you can relax.

  • Breath, like relaxation remembering to breath is key. Holding your breath is rarely a good idea.

  • Balance is critical, both for you and your camera/lens on the tripod.

  • If you can not master the finger roll, use a cable release.

  • If your hands are not on the camera use mirror lock up, or live view as a "modern" mirror lockup.

  • Image stabilization is good, and always getting better; but you can help it out. Follow this advice and remember to give your IS/VR time to figure out what it should be doing

  • Know your image stabilization. Does your lens/camera know when it is on a tripod, and what do you need to do when it is?

  • Stay out of the wind. For me nothing seems to shake me and my camera more than high wind, so I do all that I can to shield myself and my camera from it (when I can).

  • Use a lens coat. Not that the coat has stabilizing properties; but I find my lens more comfortable to touch when it is covered with soft and temperate neoprene.

  • The list goes on and on...

  • Did I mention practice?
Your milage may vary; but this seems to work well for me :)

Happy Shooting

New Canon Hybrid IS

I am sure that you have all seen this by now. I came across it late last night and was instantly glad that I have waited on trading my 300/2.8 for a 500/4.0.

I can not stop thinking about how Canon said that this fall would introduce 100 new products, and how they said that 2009 and 2010 would be the years of new lenses. Think about all the lenses that came out 10 years or so ago.

Nikon just got VR in lenses that Canon has had for quite some time. The VR is about equal to what Canon has. And now it is time for Canon's next step and that next step could be very cool.

The release is online here.

New Canon Hybrid IS world's first image stabilizer to compensate for two types of camera shake


Angle camera shake



Shift camera shake

TOKYO, July 22, 2009—Canon Inc. announced today the development of Hybrid Image Stabilizer (IS), the world's first* optical image stabilization technology that compensates for both angle camera shake and shift camera shake. The technology will be featured in interchangeable single lens reflex (SLR) camera lens planned for commercial release before the end of 2009.

Several different preventative methods and corrective procedures have been introduced to compensate for errors caused by camera shake, which occurs when a camera moves while its shutter is open and its image sensor is exposed to light.

Canon began researching methods to compensate for camera shake in the 1980s, and in 1995 launched the EF 75-300mm f/4-5.6 IS USM, the world's first interchangeable SLR camera lens to feature a mechanism that compensates for optical camera shake. Since then, the company has continued to produce a variety of interchangeable lenses with image stabilization capabilities, and boasts a total of 21 such lenses in its current product lineup.

Canon's newly developed Hybrid IS technology optimally compensates for angle and shift camera shake. Sudden changes in camera angle can significantly alter images taken during standard shooting, whereas shift-based shaking, which occurs when a camera moves parallel to the imaging scene, is more pronounced in macro photography and other close-range shooting.

The new Hybrid IS technology incorporates an angular velocity sensor that detects the extent of angle-based shaking and is found in all previous optical image stabilizer mechanisms, as well as a new acceleration sensor that determines the amount of shift-based camera shake. Hybrid IS also employs a newly developed algorithm that synthesizes information from the two sensors to make optimal adjustments, thereby dramatically enhancing the effects of image stabilization during shooting, including macro shooting, which had proven difficult for conventional image stabilization technologies.

Canon is actively engaged in ongoing research and development of interchangeable SLR camera lenses incorporating Hybrid IS technology, and is aiming for the early commercialization and inclusion of the lenses in a wide range of products.

* For use in interchangeable SLR camera lenses as of July 17, 2009. According to Canon research
