Photography and Media Camera Equipment & Technology 2 — Questions and Answers
Question 1: What type of camera viewfinder shows the scene directly through the lens via a mirror system?
- Electronic viewfinder (EVF)
- Optical viewfinder (OVF) (Correct answer)
- LCD monitor
- Rangefinder window
Correct answer: Optical viewfinder (OVF)
An optical viewfinder (OVF) in a DSLR uses a mirror and pentaprism to show the photographer the exact scene through the lens.
Question 2: What is a 'prime' lens?
- A lens with image stabilization
- A lens with a fixed focal length (Correct answer)
- A lens designed for macro photography
- A lens with an extremely wide aperture of f/1.0
Correct answer: A lens with a fixed focal length
A prime lens has a fixed, non-adjustable focal length, as opposed to a zoom lens that can change focal lengths.
Question 3: What does 'TTL' flash metering stand for?
- Total Tungsten Lighting
- Through-The-Lens (Correct answer)
- Timed Trigger Logic
- Targeted Tone Level
Correct answer: Through-The-Lens
TTL (Through-The-Lens) flash metering allows the camera to measure flash exposure by reading light that passes through the lens.
Question 4: Which camera setting controls how long the sensor is exposed to light?
- Aperture
- ISO
- Shutter speed (Correct answer)
- White balance
Correct answer: Shutter speed
Shutter speed determines the duration the camera's shutter remains open, directly controlling how long the sensor is exposed to light.
Question 5: What is 'image stabilization' (IS or VR) designed to compensate for?
- Subject motion blur
- Camera shake from handholding (Correct answer)
- Lens distortion
- Chromatic aberration
Correct answer: Camera shake from handholding
Image stabilization compensates for small involuntary camera movements caused by hand-holding, reducing blur at slower shutter speeds.
Question 6: What is the purpose of a UV filter when placed on a camera lens?
- To add color to images
- To primarily protect the lens front element (Correct answer)
- To increase contrast in photos
- To enable infrared photography
Correct answer: To primarily protect the lens front element
While UV filters were originally used to block ultraviolet light on film cameras, today they are primarily used to protect the front element of a lens.
