Ricoh GR III / GR Lens 18.3mm @ f/8 Snap Focus 2.5m — 18.3mm f/8

Cálculo óptico para Ricoh GR III (APS-C 28mm equiv) com GR Lens 18.3mm @ f/8 Snap Focus 2.5m a 2.5m: limite próximo 0.82 m, limite distante ∞, PdC total ∞ e distância hiperfocal 2.09 m.

Fórmulas Ópticas

Hyperfocal Distance H = f² / (N × c) + f
Near Focus Limit D_near = s(H − f) / (H + s − 2f)
Far Focus Limit D_far = s(H − f) / (H − s)
Angle of View AoV = 2 × arctan(d / 2f)

Frequently Asked Questions

Qual é a profundidade de campo da Ricoh GR III com 18.3mm f/8 a 2.5m?

A 2.50m de distância, a zona em foco vai de 0.82 m a ∞ e a distância hiperfocal é 2.09 m.

Como calcular a distância hiperfocal na fotografia?

A distância hiperfocal é calculada por H = f² / (N × c) + f. Ao focar na distância H, tudo desde metade dessa distância até o infinito permanece nítido.

Como funciona a equivalência de bokeh entre sensores diferentes?

Multiplicando a distância focal e a abertura pelo fator de corte do sensor, obtém-se o campo de visão e a profundidade de campo equivalentes em Full Frame 35mm.
