Photography Camera, Lenses, and Gear 2 — Questions and Answers
Question 1: What does the term 'crop factor' refer to in digital photography?
- The ratio of a sensor's size to a full-frame 35mm sensor (Correct answer)
- The amount of image cropped during post-processing
- The lens focal length multiplier applied in camera settings
- The reduction in megapixels when shooting in RAW format
Correct answer: The ratio of a sensor's size to a full-frame 35mm sensor
Crop factor is the ratio comparing a camera's sensor size to a full-frame 35mm sensor, which affects the effective field of view of lenses.
Question 2: Which lens type produces the least geometric distortion for architectural photography?
- Fisheye lens
- Tilt-shift lens (Correct answer)
- Wide-angle zoom lens
- Macro lens
Correct answer: Tilt-shift lens
Tilt-shift lenses can correct perspective distortion and keep vertical lines straight, making them ideal for architectural photography.
Question 3: What is the primary function of image stabilization in a camera lens?
- To increase shutter speed automatically
- To reduce blur caused by camera shake during handheld shooting (Correct answer)
- To sharpen edges in post-processing
- To stabilize the subject's movement in the frame
Correct answer: To reduce blur caused by camera shake during handheld shooting
Image stabilization compensates for small camera movements during handheld shooting, allowing photographers to use slower shutter speeds without motion blur.
Question 4: A lens with a maximum aperture of f/1.4 is considered:
- A slow lens with limited low-light capability
- A fast lens well-suited for low-light and shallow depth-of-field work (Correct answer)
- A standard lens with average light transmission
- A telephoto lens designed for sports photography
Correct answer: A fast lens well-suited for low-light and shallow depth-of-field work
A wide maximum aperture like f/1.4 allows more light to reach the sensor, enabling faster shutter speeds and creating a shallower depth of field.
Question 5: What does 'ED' stand for in Nikon lens nomenclature?
- Extended Distance
- Extra Depth
- Extra-low Dispersion (Correct answer)
- Enhanced Definition
Correct answer: Extra-low Dispersion
ED stands for Extra-low Dispersion glass, which minimizes chromatic aberration and produces sharper, more color-accurate images.
Question 6: Which camera metering mode measures light only from a small central area of the frame?
- Matrix/evaluative metering
- Center-weighted metering
- Spot metering (Correct answer)
- Highlight-weighted metering
Correct answer: Spot metering
Spot metering reads exposure from a very small area (typically 1–5% of the frame), giving precise control over exposure of a specific subject.
Question 7: What is a 'pancake lens' in photography?
- A lens with a very wide field of view
- An extremely compact, flat prime lens (Correct answer)
- A lens optimized for food photography
- A soft-focus portrait lens
Correct answer: An extremely compact, flat prime lens
A pancake lens is a very thin, compact prime lens that makes the camera system much more portable without sacrificing image quality.
