This article is a gallery of very fast lenses (see also lens speed) beyond average "fast" definition.
For APS-C format these are lenses with max. aperture of at least f1.4!<br(>
For 35mm film frame format these are lenses faster than max. aperture f1.7 since
the average 50mm SLR system standard lens already has a speed of f1.7 or f1.8!
For medium format these are lenses with max. aperture of at least f2.0!<br(>
For large format these are lenses with max. aperture of at least f2.5!<br(>
