22 of 50 cards from the Camera Fundamentals and Equipment deck — real questions with worked answers.

1. What is the key structural difference between a DSLR and a mirrorless camera?

   A DSLR uses a mirror and optical viewfinder: light is reflected by a mirror up through a pentaprism to the eye, and the mirror flips up during exposure. A mirrorless camera has no mirror box; light hits the sensor continuously and the image is previewed on an electronic viewfinder (EVF) or rear LCD, allowing a smaller, lighter body.

2. What distinguishes a compact (point-and-shoot) camera from an interchangeable-lens camera?

   A compact camera has a fixed, non-removable lens and typically a small sensor, prioritizing portability and automatic operation, whereas interchangeable-lens cameras (DSLR/mirrorless) let you swap lenses and usually have larger sensors and full manual control.

3. What is a medium format camera and why is it used?

   A camera with a sensor larger than full frame (e.g., about $44 \times 33$ mm digital), used for maximum resolution, dynamic range, and tonal quality in commercial, fashion, and landscape work — at the cost of size, speed, and price.

4. In a DSLR, what is the function of the pentaprism (or pentamirror)?

   It sits above the reflex mirror and flips/reorients the light reflected from the mirror so the photographer sees a correctly oriented (upright and laterally correct) image in the optical viewfinder.

5. What does the shutter in a camera do, and what are the two common types?

   The shutter controls how long light strikes the sensor (exposure duration). Common types are the mechanical focal-plane shutter (two curtains traveling across the sensor) and the electronic shutter (sensor read-out with no moving parts).

6. What is the hot shoe on a camera body?

   The metal bracket on top of the camera with electrical contacts used to mount and trigger accessories, most commonly an external flash (speedlight), as well as microphones or triggers.

7. What are the dimensions of a full-frame sensor, and what film format is it based on?

   A full-frame sensor measures $36 \times 24$ mm, the same size as a single frame of 35 mm film.

8. Define crop factor and give its formula.

   Crop factor is the ratio of the diagonal of a full-frame sensor to the diagonal of a smaller sensor: $$\text{crop factor} = \frac{d_{\text{full frame}}}{d_{\text{sensor}}} \approx \frac{43.3\ \text{mm}}{d_{\text{sensor}}}$$ It tells you how much narrower the field of view is compared with full frame for the same lens.

9. What are the typical crop factors of APS-C and Micro Four Thirds sensors?

   APS-C: approximately $1.5\times$ (Canon APS-C is $1.6\times$). Micro Four Thirds: $2.0\times$.

10. A 50 mm lens is mounted on an APS-C camera with a $1.5\times$ crop factor. What is its full-frame equivalent focal length?

    Equivalent focal length $= f \times \text{crop factor} = 50 \times 1.5 = 75$ mm, so it gives the field of view of a 75 mm lens on full frame.

11. How is a camera's megapixel count calculated from its pixel dimensions?

    Multiply the horizontal by the vertical pixel count and divide by one million: $$MP = \frac{\text{width} \times \text{height}}{10^{6}}$$

12. A sensor produces images of $6000 \times 4000$ pixels. How many megapixels is it?

    $6000 \times 4000 = 24{,}000{,}000$ pixels $= 24$ MP.

13. At the standard high-quality print resolution of 300 ppi, how do you calculate maximum print size from pixel dimensions?

    Divide each pixel dimension by 300: $\text{print size (inches)} = \frac{\text{pixels}}{300}$. Example: a $6000 \times 4000$ px image prints at $20 \times 13.3$ inches at 300 ppi.

14. Define the focal length of a lens.

    The distance (in millimeters) from the lens's optical center to the sensor when the lens is focused at infinity. It determines angle of view and magnification: shorter focal lengths give wider views, longer focal lengths magnify distant subjects.

15. On a full-frame camera, what focal-length ranges are classified as wide-angle, normal, and telephoto?

    Wide-angle: roughly $\leq 35$ mm (ultra-wide $\leq 24$ mm); normal/standard: about $40\text{–}60$ mm (classically 50 mm, close to human perspective); telephoto: roughly $\geq 70$ mm, with super-telephoto $\geq 300$ mm.

16. How does focal length affect the appearance of perspective ('compression') in a photo?

    Telephoto lenses force you to shoot from farther away, which makes background and foreground appear compressed (closer together); wide-angle lenses used up close exaggerate depth and make near objects look large relative to the background. The effect comes from camera-to-subject distance, which focal length choice dictates.

17. What is a prime lens, and what are its main advantages over a zoom?

    A lens with a single fixed focal length (e.g., 50 mm). Advantages: wider maximum apertures (faster, e.g., $f/1.8$ or $f/1.4$), generally sharper optics, lighter and simpler construction, and better low-light and shallow depth-of-field performance.

18. What is a zoom lens, and what trade-offs does it make compared with primes?

    A lens with a variable focal length (e.g., 24–70 mm), offering framing flexibility without changing lenses. Trade-offs: typically smaller (slower) maximum apertures, more optical compromises (distortion, softness at extremes), and greater size, weight, and complexity.

19. Give the formula for the f-number (aperture value) of a lens.

    $$N = \frac{f}{D}$$ where $f$ is the focal length and $D$ is the diameter of the entrance pupil (effective aperture). A smaller $N$ means a larger opening and more light.

20. What does it mean for a lens to be 'fast'?

    It has a large maximum aperture (small minimum f-number, e.g., $f/1.4$ or $f/2.8$), letting in more light so you can use faster shutter speeds in dim conditions and achieve shallower depth of field.

21. List the standard full-stop aperture scale and state the light relationship between adjacent stops.

    $f/1.4,\ f/2,\ f/2.8,\ f/4,\ f/5.6,\ f/8,\ f/11,\ f/16,\ f/22$. Each full stop halves the light (each f-number is the previous multiplied by $\sqrt{2} \approx 1.414$), because light gathered is proportional to $\frac{1}{N^{2}}$.

22. What is the difference between a constant-aperture and a variable-aperture zoom lens?

    A constant-aperture zoom (e.g., 24–70 mm $f/2.8$) keeps the same maximum aperture at every focal length. A variable-aperture zoom (e.g., 18–55 mm $f/3.5\text{–}5.6$) loses maximum aperture as you zoom in, so it becomes slower at the long end.
