Pushing the Shutter Speed Envelope

Harlequin Duck drake, head portrait. This image was created with the tripod-mounted Canon 800mm f/5.6L IS lens, the 1.4X III TC, a 25mm Extension Tube, and the EOS-1D Mark IV. ISO 400. Evaluative metering -1/3 stop: 1/8 sec. at f/14 in Manual mode. (1/8 sec. is not a typo….) Central Sensor (by necessity) Rear Focus/AI Servo AF and recompose.

Pushing the Shutter Speed Envelope

I have been amazed by the new 4-stop Image Stabilization on the Canon EF 800mm f/5.6L IS lens from the get-go. While spending two afternoons on the Barnegat Jetty recently with Denise Ippolito I decided to push the envelope and see what is actually possible with good sharpness techniques…. Here I was working with just about 30X magnification. I started making images at 1/60 sec. and then dropped down to 1/30 sec. With the duck just sitting there in lousy, lousy light I dropped that down to 1/15 sec. and finally made a half-dozen images at the ridiculously slow shutter speed of 1/8 sec. About half of all the images were sharp. The soft images were a result of either the bird moving during the exposure or having turned its head away just before I released the shutter.

Not sure why but I went back to my old-style sharpness techniques with my left hand pressing down on the base of the lens hood. After I focused and the bird held its position I held the shutter button down for 5-6 images at a time. (All with IS Mode 2.) From where I sit, this image is at least acceptably sharp. Do note that the near shoulder is totally out of focus due to lack of depth-of-field. Depth-of-field at 18 feet at f/14 with this set-up is about 1/10 of one inch. Or not much!

Do consider that there are many folks who feel that the Mongoose M3.6 does not offer enough support as good support as the Wimberley V2 with the 800 and a TC…. (Both are great heads for big glass. I prefer the lighter Mongoose while other prefer to stay away from side-mounting gimbal heads.

Why did I do it? I had nothing better to do and I am always looking to learn more about my gear. My only regret: I should have tried 1/4 second!

4-stop IS combined with amazing weight reduction are just two of the reasons that I am looking forward to the eventual release of the 500 and 600mm f/4L IS II super-telephoto lenses…. Learn more on these two lenses here.

Shopper’s Guide

Below is a list of the gear used to create the image in this blog post. Thanks a stack to all who have used the Shopper’s Guide links to purchase their gear as a thank you for all the free information that we bring you on the Blog and in the Bulletins. Before you purchase anything be sure to check out the advice in our Shopper’s Guide.

Canon 800mm f/5.L IS lens. Right now this is my all time favorite super-telephoto lens.
Canon 1.4X III Teleconverter. Designed to work best with the new Series II super-telephoto lenses.
25mm Extension Tube. An extension tube allows you to focus closer than the minimum focusing distance of your lens.
Canon EOS-1D Mark IV professional digital camera body. My two Mark IVs are my workhorse digital camera bodies.

And from the BAA On-line Store:

LensCoats. I have a LensCoat on each of my big lenses to protect them from nicks and thus increase their re-sales value. All my big lens LensCoat stuff is in Hardwood Snow pattern.
LegCoat Tripod Leg Covers. I have four tripods active and each has a Hardwood Snow LegCoat on it to help prevent further damage to my tender shoulders 🙂
Gitzo GT3530LS Tripod. This one will last you a lifetime.
Mongoose M3.6 Tripod Head. Right now this is the best tripod head around for use with lenses that weigh less than 9 pounds. For heavier lenses, check out the Wimberley V2 head.
CR-80 Replacement Foot for Canon 800. When using the 800 on a Mongoose as I do, replacing the lens foot with this accessory lets the lens sit like a dog whether pointed up or down and prevents wind-blown spinning of your lens on breezy days by centering the lens directly over the tripod.
Double Bubble Level. You will find one in my camera’s hot shoe whenever I am not using flash.
The Lens Align Mark II. I use the Lens Align Mark II pretty much religiously to micro-adjust all of my gear an average of once a month and always before a major trip. Enjoy our free comprehensive tutorial here.
Canon EOS-1D Mark IV User’s Guide. Learn to use your Mark IV the way that I use mine. Also available for the 7D and the Mark III here.
