Compact, lightweight and a wide magnification range - this standard zoom lens features a wide focal length range from normal to telephoto equivalent to 29-320mm in the 35mm format.

The normal magnification range is 60-800x.

Adding a supplementary -0.9 diopter lens turns the unit into a Betavaron 5,3...17, and changes the magnification range to 5.3-17x, and the maximum aperture to f/5.4-f/5.7.

You say we're beyond the magnification range of the telectroscope.

Another company, Redfield, produces power zoom binoculars with a magnification range of 6 to 15.

In the very low magnification range of SEM, overlapping the upper magnification of a light microscope, the superior field is limited to a varying degree by the ESEM mode.

In practice, these issues tend to significantly reduce the available magnification range on FFP scopes compared to SFP, and FFP scopes are much more expensive compared to SFP models of similar quality.

Variable power telescopic sights with SFP reticles can have slight point-of-impact shifts through their magnification range, caused by the positioning of the reticle in the mechanical zoom mechanism in the rear part of the telescopic sight.

These units can have a magnification range up to 0-7000x, are usually all-in-one (don't require a computer), and can be portable.

Low cost coaxial illumination is available throughout the magnification range for examination of glass encapsulated devices.
