Lenses & focal length
From 24mm geography to 85mm portraits — how mm, DOF, and anamorphic feel change the image, and how to write them into Studio packets.
Focal length ladder
Wider mm → more world · longer mm → more isolation
Bars get wider as focal length increases (tighter field of view)
Wide-standard
Story default · documentary-cinema hybrid
Often the “walk and talk” lens. Feels human without tele compression. Excellent multi-purpose for stills-first Studio work.
Angle
Natural-wide
Face
Good for MS/MCU if not too close
Body / space
MS with place context
Distortion
Low–moderate
Use
Hero mediums · courier medium · general coverage
Avoid
Ultra-flat beauty only looks (use 50–85)
Pairs with
Academy neon mediums · DoP default set
Packet crumb
35mm medium shot, natural perspective, subject on third
Focal length
How “zoomed” the perspective feels.
Measured in millimeters (full-frame equivalent in most prompt talk). Lower mm = wider angle of view; higher mm = tighter, more compressed. It changes perspective relationship, not just crop.
Rule
Name a focal band in DoP + every hero packet.
Studio tip
Shot list “camera” field: “35mm · locked-off.”
Lens recipes
Ready sets for Academy presets — copy into DoP or Prompt lab.
Neon courier set
Wet scope thriller
Focal plan
35mm coverage · 50mm identity
DOF feel
Medium-shallow on MCU; deeper on wides
Format
2.39 anamorphic feel
When
Alley stills A01–A03
Packet
35mm medium, anamorphic 2.39 feel, teal rim, wet reflections; identity CU on 50mm shallow DOF
Cheat sheet
mm + DOF + format pattern
LENS CHEAT (Studio Academy) Bands (FF-equivalent) • 14–20 ultra wide — scale / distort • 24–28 wide — place + person • 35 story default • 50 normal / identity • 85 portrait compression • 100–135 tele isolation Rules 1. Name mm in DoP + hero packets 2. Identity CUs: 50–85 — don’t only crop wides 3. 3–4 focal lengths max per mini-project 4. Pair anamorphic wording with 2.39 (not 9:16) 5. DOF is story: shallow isolate · deep geography 6. Perspective ≠ digital zoom crop Prompt pattern [shot size] · [mm] · [DOF] · [aspect/format] e.g. medium close-up, 50mm, shallow DOF, 2.39 anamorphic feel
