Questions & answers
Frequently Asked Questions
Which sensor assumptions are fixed for focal length mm to full-frame equivalent mm?
Focal length mm to full-frame equivalent mm is fixed to Compact 1/2.5" class, crop factor 6.8, sensor width 5.76 mm.
How do I reverse mm to eq mm for Compact 1/2.5" class?
Use the opposite-direction page for Compact 1/2.5" class to convert 35mm equivalent focal length (mm) back to focal length (mm) with the same sensor assumptions.
Can focal length mm to full-frame equivalent mm replace full lens-design simulation?
No. Focal length mm to full-frame equivalent mm provides framing and geometry approximations, not full optical-model behavior.
