Stabilisation uses a marker in the manufacturer model name; no marker is not a negative claim. Price filters use a current price when available.
One limit of this table: it lists only Sony E lenses that mount natively on the Sony a7 IV — lenses fitted through an adapter are not included here. See which mounts adapt to which.
How long can you expose before the stars trail on the Sony a7 IV?
A rule-of-thumb answer for each lens above, at its widest focal length and widest aperture. The NPF rule takes the Sony a7 IV's pixel size into account; the older 500 rule does not, and gives longer times that can show slight trails on today's sensors.
