HSM
AF = Auto Focus
AL = Aspheric Lens
ED = special glass prevents chromatic aberration to a great extent
DC

SP = Super Coating (af forreste linseelement)
Lanthar = one or more elements made of lanthanum (rare earth) glass
SDM = Supersonic Direct-drive Motor

Jeg har søgt og fundet svar på nogle af benævnelserne men hvad betyder
resten?
Der er tale om Pentax, Sigma, Tokina, Tamron, Voigtlander, Vivitar og
andre pentax bajonet kompatible objektiver.

> EX

EX (EX Lens)
The exterior of this lens is EX-finished to denote the superior build
and optical quality, and to enhance its appearance.

> DG

DG (DG Lens)
These are large-aperture lenses with wide angles and short minimum
focusing distances. With an abundance of peripheral illumination, they
are ideal lenses for Digital SLR Cameras whilst retaining suitability
for traditional 35mm SLRs.

> HSM

Hyper-Sonic Motor
This lens uses a motor driven by ultrasonic waves to provide a quiet,
highspeed AF.

> DC

DC (DC Lens)
These are special lenses designed so that the image circle matches the
smaller size of the image sensor of most digital SLR cameras. Their
specialized design gives these lenses the ideal properties for digital
cameras, the compact and lightweight construction is an added bonus !
including compact and lightweight construction.

DC skrives også som 'Digital Compliant'

> FE

FE & FD er ældre Canon bajoneettyper til ikke-AF kameraer

FE bruges også om specialglas fremstillet af meget jernholdigt sand.
Skulle give en meget lav abberation og en meget fin og jævn brydning.

> A

Minolta A-bajonet

Bruges også om ældre optik med automatisk nedblænding

> IF = Inner Focusing

Skrives også ofte 'Inline Focusing'

> M

M = Manual eller 'M mount', bruges om optik med klassisk gevind 'M
gevind'. Kaldes også for 'Leica gevind'

> K

Standard K bajonet, det mest udbredte bajonetformat. Opr. lavet af
pentax. bruges/brugtes af bl.a. Pentax, Praktica, Exa/Exakta, Ricoh,
Chinon, Carena, visse Mamaya modeller, Zenith, Zorki, AKW, m.fl.

> SP = Super Coating (af forreste linseelement)

Bruges også om optik, der er speciel velegnet til brug ved spotmåling -
SP = Spot Measurement'. Opr. int. af Pentax på deres nok så berømte
Pentax K1000 Spotmatic.

> Lanthar = one or more elements made of lanthanum (rare earth) glass

'Lanthar' er også navnet på et 55mm/f:1,7 Leitz objektiv, der blev brugt
på bl.a. den første Leicaflex
