A superzoom or hyperzoom lens is a type of photographic zoom lens with unconventionally large focal length factors, typically ranging from wide angle to extreme long lens focal lengths in one lens. There is no clear definition of a superzoom lens, but the name generally covers lenses that have a range well above the 3× or 4× of a standard zoom lens, with lenses being 10×, 12×, 18×, or above considered superzoom.

The Pentax K-mount, sometimes referred to as the "PK-mount", is a bayonet lens mount standard for mounting interchangeable photographic lenses to 35 mm single-lens reflex (SLR) cameras. It was created by Pentax in 1975, and has since been used by all Pentax 35 mm and digital SLRs and also the MILC Pentax K-01. A number of other manufacturers have also produced many K-mount lenses and K-mount cameras.
Originally produced as Konica Minolta AF Zoom DT 18-200mm f/3.5-6.3 (D) by Konica Minolta in 2005, and currently produced by Sony, the Sony α DT 18-200mm f/3.5-6.3 (SAL-18200) is compatible with cameras using the Minolta A-mount and Sony A-mount lens mounts. The DT designation means this lens is designed to be used with a camera with an APS-C size sensor. When the 1.5× crop factor is considered, the lens has an effective equivalent 27–300mm focal length. The lens is derived from the Tamron AF 18-200mm f/3.5-6.3 XR Di II LD Aspherical [IF] (models A14M/A14S).

The Tamron 16-300mm F/3.5-6.3 Di II VC PZD MACRO is a superzoom lens designed for digital crop sensor cameras.
Zoom creep is a phenomenon in zoom lenses where the angle of view of the lens changes when gravity is allowed to freely act on it. If the lens has a zoom ring, holding it when the lens is held upwards or downwards will prevent this change. In lenses with push-pull zoom, creep is prevented by holding the extending part of the lens. Some lenses, such as the Tamron SP AF 17-50mm f/2.8 XR Di II LD Aspherical [IF] and Canon EF-S 18-135mm f/3.5-5.6 IS STM, have a zoom lock to stop the effect.

The Tamron SP 150-600mm F/5-6.3 Di VC USD is a super telezoom lens for DSLR cameras, announced by Tamron on November 7, 2013. The Sony A mount version is called Tamron SP 150-600mm F/5-6.3 Di USD as it lacks image stabilisation.
The Tamron AF 18-200mm F/3.5-6.3 XR Di II LD Aspherical [IF] Macro is a superzoom lens by Tamron, initially announced in 2005.

However, in 2008, the 18-200 model was re-released with a built-in motor for Nikon bodies lacking a motor in the body - at that time the Nikon D40, D40x and D60.

On Pentax APS-C cameras, the D FA 70–210mm has an equivalent focal length range of 107–322mm.
