Negatives: No zooming; you should compose by moving the digital camera.
Wide-angle lenses: They range from 24mm (bordering on ultrawide) to 35mm (bordering on semiwide). Just like normals, the selection is between pretty compact, single-focal-length lenses of fairly large aperture (f/two-file/two.eight, several file/one.4s) and moderate-aperture zooms (all around file/3.5-four.five), which give superior framing adaptability. For positives and negatives on the two kinds, see typical-lens segment above.
Many wide zooms, including 24-50mm, 25-50mm, 28-50mm, etcetera., encompass typical along with wide-angle focal lengths, which can be a benefit.
