Additionally, three dedicated image stabilization modes are available—Standard, Panning, and During Exposure Only—and can be selectively employed to suit a variety of types of shooting.
A ring-type Ultrasonic Motor USM , along with optimized focusing algorithms and a high-speed CPU, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.
The rotation-type zoom ring offers precise adjustment between zoom positions, especially when shooting handheld, and a zoom torque adjustment ring enables easy setting of the zoom tension for personalized control.
A weather-resistant design protects the lens from dust and moisture to enable its use in inclement conditions. Additionally, fluorine coatings have also been applied to the front and rear lens elements for further protection against fingerprints and smudging. Rounded nine-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.
A redeveloped tripod collar can be attached or detached from the lens without having to remove the lens from the camera. The included ETD lens hood incorporates a side window for easier adjustment of rotating filters with the hood in place.
Made from aluminum, the 3-section legs are secured via twist locks and extend to a maximum height of The center column can be replaced with the included short column to allow the tripod to reach a minimum height of The rubber feet can be swapped out for metal spikes so that the tripod can be used on hard surfaces, such as ice, or soft surfaces, like carpeting or a lawn.
A ballast hook on the center column allows for the addition of stabilizing weight, and the included carrying case protects the tripod during transport. An ideal support for sports and wildlife photographers, this head is capable of handling a 44 lb payload and allows fluid movement on both vertical and horizontal axes.

Add your rating and experience with the product. I ended up buying both the 2x extender and new lens and it turned out to be a good decision. In short, the image stabilization on the mark II lens is indeed amazing even with the 2x extender and well worth the investment. I had read numerous online posts from "experts" that an extender will make the images look soft and that you will lose contrast. I decided to put this to the test.
I want to be able to take wildlife headshots that show whisker detail from far enough away that there's no danger of getting my face ripped off or getting gored. So I set up a resolution test chart 75 yards away in a somewhat open forest that had dappled light, probably the worst conditions that I could expect to be successful in.
I then took multiple photos and varied the following: Old and new lens, no extender, 1. Shutter speeds were slow at reasonable ISO settings due to the light and gave a good test of real world conditions.
I found the following:. Mounted on a secure tripod and without an extender both the old and new lens gave approximately the same maximum resolution about 12 lines per inch at 75 yards, the resolution limit is driven by the number of pixels in the camera, not the lens.
When using the extender, even when mounted on a tripod, you will need to set the shutter to high speed continuous and take 4 to 6 images so that you get at least a couple good images.
Breezes and shutter vibration will cause some movement during exposure. The 2x extender was more useful than the 1. With a 1. The real difference between the two lenses is the image stabilization. A hand held shot with the old lens at mm was laughable; it was just one big blur. The image stabilization with the new lens makes hand held shots possible if you are leaning against a support with your elbows tucked in and control your breathing or rest the lens on support.
You will need to set the shutter to high speed continuous and take 5 to 10 images. Here is a jpg copy of a test shot I did handheld. I found the best tradeoff of ISO, f stop, and shutter speed at mm to be ISO , f11, and as fast a speed as lighting will permit. That was true whether handheld or using a tripod. As you can tell from the resolution chart, I won't be getting any bear photos showing whisker detail any time soon, even 25 lines per inch won't capture that.
Why aren't you shooting faster shutter speeds handheld? I was taught to double my focal length to get a shutter speed that will be sharp when shooting handheld. Am I correct in that auto focus with the 2x extender will work with the non IS but will not with the IS version? I have the IS i. Also, some within this thread said that auto focus at F8 does not work. I used my IS F8 to shoot surfing photos recently and didn't have a problem with auto focus, my body is a 6D.
I was taught the same thing, but that was before image stabilization came to lenses. My real life testing was done to quantify the best combination of speed, aperture, and ISO for the Mark II lens on a 70D camera both with and without the 2x extender.
The new II lens has amazing image stabilization which will allow you to shoot at the slower speeds required for f11 and lower ISOs. Focus for both the old and new lens with the extender will work only in "live view" using a 70D camera, but it works well. If you like to view through the lens when you take photos, focus in live view first, switch to manual focus, turn live view off and then compose through the viewfinder.
Just remember not to touch the focus ring. Next Page. Camera Lens Canon FK Page 2 Thank you for purchasing a Canon product. Doing so could result in loss of vision. Looking at the sun directly through the lens is especially hazardous. Page 5: Focusing Ring 1. Page 6 3. Switching the Focusing Distance Range You can set the focusing distance range to 1. By setting the suitable focusing distance range, the actual autofocusing time will be shorter.
If you use AF from outside the specified focusing distance range, the lens may stop focusing when it reaches the limit of the range. Page 7: Zoom Ring 4. Adjusting Zooming Resistance Move the zoom ring forward or backward to zoom. Changing the zoom ring after focusing can affect the focus. Page 8 5. Page 9 6.
