Tips on Using the Image Stabilizer The Image Stabilizer also operates when the lens is used with extension tube EF12 II or EF 25 II or the extender EF 1.4 x III or EF 2 x III . Depending on the camera there may be image shake, such as after releasing the shutter. However, this does not affect shooting.
If the batteries do fail, the EF can still be used manually from 1/ 2 - 1/1000 sec. The Variable Aperture AE control will not operate, but you can manually adjust the aperture ring of the lens. A basic exposure guide to follow for bright sunlight (with distinct shadows) is to make a fraction representing the shutter speed needed at f/16 by putting a "one" over the film's ASA rating.
This indicates that the film has left the multi-slot take-up spool. Turn the rewind crank one or two more revolutions to completely rewind the top of the film leader back into the cartridge. The pull up the rewind knob to open the camera back and lift out the cartridge.
Lenses that support changes in the AF speed Extender 1.4 x EF-S 10-18mm f/4.5-5.6 IS STM EF -S 15-85mm f/3.5-5.6L IS USM EF-S 18-55mm f/3.5-5.6 IS STM EF-S 18-135mm f/3.5-5.6 IS STM EF-S 55-250mm f/4-5.6
You can attach extension tube EF12 II or EF25 II for magnified shots. The shooting distance and magnification are shown below. Focusing Distance Range (mm) Magnification ( x ) Close distance Long distance Close distance Long distance EF 12 II 3265 20570 0.18 0.03 EF 25 II 2904 9917 0.22 0.06
