Lenses that support changes in the AF speed USM EF 400mm f /4 DO IS II USM EF 11-24mm f /4L USM EF 50mm f/1.8 STM EF 35mm f /1.4L II USM EF-S 18-135mm f /3.5-5.6 IS USM EF 24-105mm f /4L IS II USM EF 70-300 mm f/4-5.6
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. With a film of ASA 100, use 1/100 sec.
