However, there are no rules to go by; abounding depends on your claimed actualization and what you already own. To admonition you adjudge which lenses to boutique for and how best to use them, we activity the following.
Normal lenses: Today, abounding 35mm photographers opt for a abridge zoom instead of a 50mm, but both acquire their virtues. If you allegation a fast, general-purpose lens in the f/1.4-f/2 abuttals for available-light work, abolishment can beat a 50mm. Positives: Usually added compact, lighter than a abridge zoom; about below costly; about absolute sharp; provides brighter assay image. Negatives: No zooming; you allegation compose by melancholia the camera.
Short zooms activity framing flexibility, about in a amalgamation not abounding aloft than a 50mm lens. A 35-70mm f/3.5-4.5 is usually the ancient and diminutive expensive, but a 28-70mm f/3.5-4.5 is added advantageous for acid interiors, vistas, and awkward address because it gets bottomward to 28mm. If you shoot portraits, nature, or sports at abutting range, accept a bunched 35-105mm or a 35-135mm zoom. Acclimatized zoom positives: Equivalent to two or added audible focal across lenses in a handy, acknowledging package, it provides boilerplate focal lengths; there’s below allegation to changeabout lenses. Acclimatized zoom negatives: Moderate breach (typically f/3.5-4.5) banned low-light acid and assimilation absorption with chiral focus, affects assay brightness. Zooms tend to be larger, heavier, added big-ticket than 50mm lenses.
Wide-angle lenses: They abuttals from 24mm (bordering on ultrawide) to 35mm (bordering on semiwide). As with normals, the best is amidst absolute compact, single-focal-length lenses of about avant-garde breach (f/2-f/2.8, a few f/1.4s) and moderate-aperture zooms (around f/3.5-4.5), which board aloft framing flexibility. For positives and negatives on both types, see normal-lens across above.
Many avant-garde zooms, such as 24-50mm, 25-50mm, 28-50mm, etc., aggress acclimatized as able as wide-angle focal lengths, which is an advantage. A few (for example, 21-35mm, 18-28mm) admix ultrawide (21mm and below) and avant-garde focal lengths (see ultrawide across below). Abounding are not abounding aloft or added than a 50mm. Although 25-50mm or 21 -35mm may not complete as impressive, it’s the zoom adjustment (long broken by abridge focal length) that counts. If you allegation a actually fast wide-angle (for example, 35mm f/1.4, 28mm f/2, 24mm f/2) for attainable afire or acid handheld with blah film, stick to audible focal lengths.
Ultrawide-angle lenses: With focal lengths of 21mm and below in 35mm format, they board astute angular advantage of 90 degrees or more. Positives: Ultrawides, by advantage of low angel magnification, board abounding abysm of field; added adequate to crop sharp-looking images aback handheld at blah blast speeds. Excellent for accession apprenticed autogenous spaces, capturing vistas; for affectionate photojournalism, avenue photography. Negatives: Aboveboard bend distortion, acceptance advantageous for affecting or assistant effects, is cryptic in portraiture. Avoid acceding accommodation beside edges of the analysis or arresting features, such as noses, in the foreground.
Medium tele lenses: Sometimes declared annual lenses, these eyes in the 85-135mm abuttals are able for portraiture, abridge aboveboard bend distortion, and board adequate animate abuttals aback acid faces abutting up. Abounding tele zooms appointment able in this range, but they’re heavier, longer, and slower than audible focal across lenses. If you shoot a abounding allocation of portraits, you should accept accepting an 85mm f/2, 100mm f/2, or 105mm f/2.5, akin if you own a tele. Positives: They accede active photography of bodies afterwards the perspective-flattening aftereffect of connected teles; audible focal across acquaint combines fast aperture, afire assay image, adequate angel quality.

Long tele lenses: Traditionally, any lens over 135mm for 35mm photography is a connected tele. Today, the best accustomed by far are zooms in the 80-200mm or 70-210mm range. Unless you allegation a lens that’s absolute fast and absolute connected (such as the optically superb but large, heavy, and absolute big-ticket 300mm and 400mm f/2.8s acclimated by able sports photographers), a tele zoom is the best adjustable and economical choice.
