Screen Filter Slr
i need help with some vocab for photography classs.?

so i have this vocab sheet and im supposed to define some stuff of a camera, help would be appreciated. =D

1. standard lens
2. manual override
3. uv filter
4. cheap lens image quality?
5. slack
6. split image focusing screen
7. which film is faster 100asa or 400asa, and how do you know?
8. dx
9. shutter speed control
10. list slowest to fastest shutter speeds on a 35mm slr
11. what 2 things do shutter release do?
12. 3 things happen when click the shutter?
13. list the f-stops from smallest to largest size

1. a lens that accurately approximates the view of human eyes with a focal length of 50mm.
2. Setting the dial to M. The camera does not make decisions about aperture, shutter, and iso; you do.
3. a filter attached in front of a lens that block uv light. Usually used to protect the lens from scratches and smudges.
4. huh?
5. huh?
6. the image you see through the viewfinder of a SLR camera. When you remove the lens, you can see the focusing screen reflected in the reflex mirror of the slr.
7. 400. Because it is more sensitive to light.
8. aps-c image sensor size. 1.5x crop from "full-frame" or 35mm
9. controls the shutter speed. Could be a dial, or adjusted from the menus.
10. wow, this depends. Probably 15" to about 1/2000 of a sec.
11. It controls the exposure. Faster shutter speeds means image is less likely to blur due to camera shake or subject movement.
12. the mirror flips up, shutter opens, film or ccd is exposed to light
13. 22-1.4

Wow seriously, doesn't the instructor go over all this in class? XD
