Maximum apertures span a wide range: very fast primes (around F1.2–F1.4), constant-aperture professional zooms (commonly F2.8), and much slower super-telephoto zooms with variable maximum apertures (roughly f/6.3–8).

Many lenses list weather‑resistant design features such as dust‑ and splash‑resistant or moisture‑resistant sealing. Several also include protective front‑element coatings (for example, fluorine coatings) to repel contaminants and make cleaning easier.

The listings include lenses optimized for both APS‑C (Sony E‑mount APS‑C) and full‑frame Sony E‑mount cameras. Some entries are explicitly APS‑C designs while others are full‑frame lenses.

Several lenses emphasize circular multi‑blade apertures (examples cite 11‑blade circular diaphragms) plus optical designs—such as aspherical, XA, or ED elements—and anti‑flare coatings to produce smoother, creamier out‑of‑focus backgrounds (bokeh).
