35mm vs 40mm: Does 5mm Actually Matter When You Can't Step Back?

Five millimetres sounds like nothing until you're backed against a wall at a corporate event or shooting on a narrow trail with a 200-metre drop behind you. The real question this test answers isn't which focal length is 'better' — it's whether 35mm gives you a meaningful bailout when 40mm leaves you short. Worth a read if you're debating a single prime travel kit and shooting anywhere with hard physical limits on your position.
