Photography Equipment/Lenses/Canon standard

A standard lens is a general-purpose lens, which captures the middle of the focal length range. These can be a normal lens (standard prime), or a standard zoom, often the kit lens. Some common recommendations follow. General Purpose Canon Lenses (from The-Digital-Picture) APS-C Canon's small sensor cameras mostly use a 1.6x crop factor (except for the 1D series, which is 1.3), so a normal lens would be 50mm/1.6 = 31.25mm, and focal lengths for standard zooms are correspondingly shorter than on full frame standard zooms. Standard Zoom Kit lenses Canon EF-S 18-55mm: kit on Rebel series, considered very soft FF FOV equivalent of 29-88mm, EF-S analog of Canon EF 28-90mm Canon EF-S 17-85mm IS USM: kit on 30D, 40D FF FOV equivalent of 27-136mm, EF-S analog of Canon EF 28-135mm (The-Digital-Picture review) (Bob Atkins review) Non-kit lenses Canon EF-S 17-55mm ($1,300) excellent standard lens FF FOV equivalent of 27-88mm Notable features: high-quality glass (similar to L series, though lower build quality), and at f/2.8, quite fast for a zoom. (Philip Greenspun Review at photo.net) (Fred Miranda Review) (The-Digital-Picture.com Review) (dpreview.com Review) Standard Prime A normal lens on a 1.6x crop factor camera would be about 31mm. Canon doesn't make a prime lens at this point, but does make some EF wide-angle lenses that can work. Others instead suggest the Sigma 30mm f/1.4 as the best prime normal lens for Canon APS-C cameras. Canon EF 28mm: f/2.8, f/1.8 Canon EF 35mm: f/2 ($200); f/1.4 L USM ($1,100) Sigma 30mm f/1.4 for Canon ($400) Recommended by Philip Greenspun at photo.net. Full Frame Standard Zoom Canon EF 28-135mm Standard Prime a Canon EF 50mm: (Comparison of Canon 50mm lenses, at The-Digital-Picture) (Other comparison, at photo.net) 50/1.8 II is high quality and excellent value ($75), 50/1.4 is more expensive ($300) but widely praised, and 50/1.2 is very expensive ($1,300) but very fast.
