ASM modes
The camera does have aperture- and shutter-speed priority modes as well as full manual. However, they are a pain to use because you have to open up the Fn menu every time you want to change the settings. Also, if you decide you want to switch from one mode to another, you either have to go two steps into the main menu system or turn the mode dial out of and back into the ASM position. Apertures at the wide end include: f3.2, f3.6 f4.2,f4.6, f5.2, f5.8, f6.6, f7.3, f8.3, f9.3, f10.3, f11.6. With the lens full extended you get: f5.8, f6.8, f7.6, f8.3, f9.6, f10.7, f12.0. Shutter speeds range from 16 seconds to 1/2,000 of a second.
