A Practical Guide to Lens Selection and Perspective
Choosing focal length for the perspective it produces, not only for how much fits in the frame.
Imogen Clarke
Where most projects go wrong
The usual mistakes:
- Wide lenses close to products, which distorts proportions
- Changing focal length between products in one range
- Cropping heavily instead of using an appropriate lens
- Assuming distortion can always be corrected afterward
What good looks like instead
- Choose the distance for the perspective you want, then the focal length to frame it
- Use longer focal lengths for product work to avoid distortion
- Use a macro lens for genuine close-up work rather than cropping
- Keep focal length consistent across a product range
- Check for distortion and correct it with a lens profile
Why it matters
Focal length changes the apparent relationship between near and far parts of a subject, which is why some product shots look subtly wrong.
The specs that matter
| Measure | Figure |
|---|---|
| Perspective | determined by camera-to-subject distance, not by the lens itself |
| Focal length | determines framing from a given distance |
| Longer lenses | compress apparent depth |
| Wider lenses used close | exaggerate near features |
| Macro | lenses designed for close focus at high reproduction ratios |
Knowing when to hand it over
Tip: Bring in help when products must be shown dimensionally accurately, when existing images show distortion, or when a range must match imagery shot elsewhere.
