A photographer is building a one-lens kit specifically for e-commerce product photography. Which single focal length is most versatile?
Answer: 50mm macro prime
A 50mm macro prime delivers natural perspective, close focusing capability, and sharpness needed for most e-commerce product sizes.
When is a zoom lens preferred over a prime lens in a product photography studio setting?
Answer: When quickly varying the framing of many different product sizes saves time
Zoom lenses offer flexible framing without physically moving the camera, which is efficient when shooting many differently-sized products.
What is the 'reproduction ratio' of a lens, and what ratio does a true macro lens achieve?
Answer: The size of the subject on the sensor vs real life; true macro achieves 1:1
Reproduction ratio describes how the real subject size maps to sensor size; 1:1 means the subject is rendered life-size on the sensor.
A studio photographer notices soft corners in product flat lay images. What is the most likely cause?
Answer: The lens is being used at its maximum aperture where corner sharpness is weakest
Most lenses exhibit soft corners wide open; stopping down 2–3 stops typically improves corner sharpness significantly.
For photographing a product through a glass surface (like a display case), which filter helps reduce reflections and increase color saturation?
Answer: Circular polarizing filter (CPL)
A circular polarizing filter blocks polarized light reflections from glass surfaces, allowing the product inside to be photographed more clearly.
Why might a product photographer choose a lens with optical image stabilization (OIS) even when shooting on a tripod?
Answer: OIS can reduce mirror vibration effects on shorter exposures
Some OIS systems help dampen minor vibrations from mirror slap or studio floor movement even on a tripod, though many photographers disable OIS on a tripod.
A photographer using a full-frame camera switches to an APS-C crop sensor camera with the same 100mm lens. How does this affect product framing?
Answer: The effective focal length increases (by ~1.5x), so the product appears larger in frame
A 1.5x crop factor makes the 100mm lens behave like a 150mm, tightening the framing and making the product appear larger.
