DOF means depth of field. OOF means out of focus. They are the two most common ones.

There is a list of abbreviations somewhere, I'll try and find it for you.

 

[BRASH]

Found the list I had saved but it relates to text speak and not photography so not really relevant. You can Google them though and you'll usually come up with a result. Hope this helps. Cheers.

 

[Rach]

that was the other one i had seen a few times but couldnt remember when i first posted
thank you for clearing those two UP

There's one or two others (bloomin 'eck - I'm sure I've missed a pile out though)


Canon-specific:

AFD – Arc-Form Drive: An older type of in-lens AF motor like USM but slower and noisier.

AL - Aspheric Lens: A special design lens used to minimize aberrations. Aspheric lenses can be designed more compact and lightweight then conventional lenses.


CA – Circular Aperture: Canon lenses with multiple aperture blades shaped to give as circular an iris shape as possible, effects the bokeh.

CaF2 – Fluorite Element: Very expensive material used in place of glass, offers great resolution and color accuracy. Corrects chromatic aberrations even more then Super **. Mostly used in L-series and super-telephoto lenses.

EOS –Electro Optic System: Canon’s current SLR camera system which was introduced in 1987.

EF – Electronic Focus: Canon’s current standart lens mount designation. It is compatible with all EOS bodies

EF-S: Lens mount designation for Canon's APS-C DSLRs (EOS 300D-Digital Rebel, 350D-Digital Rebel Xt, 400D-Digital Rebel Xti, 20D, 30D, 40D). EF-S lenses are not compatible with film SLRs and DSLRs that that don’t have EF-S mount (full frame and 1.3x crop sized sensor)

E-M – Electronic Manual Focusing: Old type of USM lenses which deploys USM motor for electrically manual focusing.

FT-M – Full-Time Manual Focus: Manual focus is possible with lens in AF mode for fine adjustment of focus.

I/R – Internal or Rear Group Focusing: I/R lenses doesn’t change length and the front element does not rotate. Very useful for with a polarizer filter.

IS – Image Stabilization: Canon’s optical based stabilisation system that reduces the vibrations, works similar to VR – Nikon, OS – Sigma, VC – Tamron, O.I.S – Panasonic

L – Luxury: The designation that Canon gives to its professional range of lenses. Almost all L-series lenses have white color bodies and the red ring around the barrel.

MP-E – Macro Photo Electronic. Specialised Canon lenses designed for macro photography. MP-E lenses are manual focus and E (Electronic) refers to the electronic aperture control.

Super ** – Super Ultra-Low Dispersion glass: More effective than ** for correction of chromatic aberration

T/S (TS-E) – Tilt/Shift. These are the lenses that can be shifted and tilted to control the plane of focus and correct perspective distortion. Used especially for architectural and studio works.

** – Ultra-Low Dispersion Glass: Special glass used for correction of chromatic aberration

USM – Ultrasonic Motor: Auto focusing motor that offers fast and silent focusing using piezoelectric elements. There are two types;

• Micro–USM: Low-cost but slower, does not support fulltime manual focus.
  
• Ring–USM: Faster and features fulltime manual focus override without switching off AF.

Nikon-specific:

A -- The original bayonet lens type (1959). Manual focus lens. Considered Pre-AI

ADR -- Aperture Direct Readout. A fancy way of saying that aperture scale can be seen directly by the cameras that have overhanding prisms (ala F4, F5). Started with AI lenses in 1977.

AF-I -- An autofocus lens with an Integrated, coreless focus motor (1992). All AF-I lenses are D-type, but some older bodies can't autofocus with them (N60, N8008).

AF-S -- An autofocus lens with a Silent wave, integrated, coreless focus motor (1996). Basically an update to AF-I. Some older bodies can't autofocus with them (N60, N8008). Some newer bodies (D40, D40x) can only autofocus with them.

AI -- Aperture Indexing (1977). Manual focus lens.

AI-P -- An AI lens variant (1988) that was "chipped" to send data to the camera.

AI-S -- A variant of AI designed to be used with Program and Shutter-priority exposure modes (1982). Manual focus lens. Distinguished by smallest aperture being printed in orange and a small scoop on the bayonet flange, which transmits aperture info. Otherwise same as AI.

ASP -- Lens has aspherical elements in its optic design. Aspherical lenses eliminate coma and other types of lens aberrations by using complex curves in the design of lens elements.

C -- A lens coating type (Nikon Integrated Coating) for Pre-AI lenses. Distinguished by a C after the lens designation and a black filter ring.

CRC -- Close Range Correction, means that the lens was designs to provide superior focusing at close distances and with flat fields.

D -- (1992) Adds distance information to the data transmitted to the camera via chip. Distinguished by the D or G after the lens designation.

DC -- Defocus Control lens, allows the photographer to change the degree of spherical aberration in the out-of-focus areas to provide for better bokeh.

DX -- (2003) Indicates a lens designed to cover the smaller image circle of the digital camera bodies. May still work on 35mm bodies at some focal lengths.

E -- A special type of AI lens (1977) introduced with the consumer-oriented EM body. Says Nikon Series E on the lens. Light in weight, plastic in construction, but optically good.

ED -- Extra-low Dispersion element(s) used in the lens.

FX -- (2007) 35mm full frame digital sensor. While Nikon doesn't explicitly use this acronym yet with lenses, it has used it casually to refer to lenses that cover the full 35mm film (and FX digital sensor) frame, as opposed to lenses that cover smaller imaging sizes, such as DX or IX.

G -- Removes the aperture ring from a D-type lens. Thus needs to be used on camera with Command dial control of apertures. With some older cameras (N90s, for example), can be used in Program or Shutter-priority exposure mode, though.

IF -- Lens uses internal focusing rather than moving or turning outer elements.

IX -- Lenses for the Pronea system (Advanced Photo System). Can't be used on the 35mm or digital bodies.

K -- Another Pre-AI lens type, this time with rubber focus rings.

N -- Originally, the actual designation used for the first AI lenses; beginning in 2005 it now stands for Nano Crystal Coat, a special type of flare reduction coating applied to newer lenses.

N (gold emblem)-- Nano coating. A crystalline coating that eliminates internal lens element reflections, reducing ghosting and flare.

NIC -- Nikon Integrated Coating. A fancy way of referring to Nikon's glass coating system, which is used to help reduce flare and ghosting.

PC -- Perspective Control lens, allows the front of the lens to be shifted relative to the rest of the lens to correct for perspective. All PC lenses are either AI or AI-P in type.

RF -- Rear Focusing, means that lens achieves focusing by moving the rear elements; similar to IF.

SIC -- Super Integrated Coating, a multi-layer flare reduction coating, usually applied to the more complex zoom lenses.

SWM -- Silent Wave Motor. This is the motor in the lens used in AF-I and AF-S lenses.

VR -- Vibration Reduction lens, corrects for camera movement during exposure. VR function only works on post F5 cameras (e.g., not F4, N90s, N60, N70, N8008). Lately, Nikon has been using a VRII designation to indicate some advances to the vibration reduction system.

SIGMA:

EX EXPERT RANGE Better build quality and optical design for the more discerning user.

CONV CONVERTER USABLE The lens is recommended for use with one of Sigma's optional teleconverters.

APO APOCHROMATIC GLASS Apochromatic glass is used in the lens to minimise chromatic aberration.

ASP ASPHERICAL GLASS Aspherical type elements are used in the construction of the lens.

DC DIGITAL CROP ONLY The lens can only be used on cropped sensors of APS-C size.

RF REAR FOCUS - The lens focuses with a rear group of elements and a rear focus ring. The lens does not change length when focusing.

DG FULL FRAME AND CROP DIGITAL Used to denote lenses that have been designed to work on full-frame / 35mm sensors as well as cropped sensors

OS OPTICAL STABILIZER Sigma's own advanced stabilisation system to help reduce camera or user shake when shooting at slow shutter speeds.

HSM HYPERSONIC MOTOR Sigma's version of a sonic drive motor for the autofocus system. Quicker and quieter than traditional rotary motors.

IF INTERNAL FOCUS Internal focusing means that the lens does not change size during the focus operation.

Tamron:

-AD A lens with Anomalous Dispersion element(s), a special optical glass which delivery large partial dispersion ratios relative to a specific light wavelength zone.
-AF Autofocus

-ASL Aspherical Lens Elements. A type of lenses that virtually eliminates the problem of coma and other types of lens aberration. The are particularly good at correcting distortion in wide-angle lenses as well as contributing to a lighter and smaller lens design.

-Di Digitally Integrated Design. Optical system designed to meet the performance characteristics of DSLR cameras as well as film cameras. Lenses can be used with either Digital or Film SLR cameras.

-Di II Digitally Integrated Design. Lenses made exclusively for digital SLR cameras with image sensors smaller than 24mm x 16mm (APS-C). Features high resolution performance incorporating anti-reflection coating and optical configurations to compensate for internal reflections and ghosting. Peripheral light fall off, more noticeable with digital cameras, is also reduced. Also provide ideal focal lengths to cover the range desired by DSLR users. Not designed for Full Frame Digital SLR cameras.

-HID High Index High Dispersion Glass element. Minimises on-axis and lateral chromatic aberrations.

-IF Inner Focus. The lens is able to focus without physically changing its size, where optical movement is limited to the interior of the non-extending part of the lens barrel, allowing for a more compact and lightweight lens as well as closer focusing distances.
-LAH LD Hybrid aspherical elements.

-LD Low Dispersion elements which effectively compensate for chromatic aberration that is a problem at the telephoto end and lateral aberration at the wide angle end.

-MACRO Used on those lenses which have the ability to be used for close up (macro) photography. Tamron puts MACRO on those lenses that provides a magnification ration of 1:4 or greater, indicating it is capable of providing macro results.

-SP Super Performance. High performance Specifications. The first priority in producing these lenses have been superior specifications and outstanding performance free from cost restraints.

-VC Vibration Compensation. Uses a 3 coil system allowing lenses to remain compact in size. Gives smooth and steady images in the viewfinder.

-XR Hi Refraction index glass elements resulting in minimum aberration. Allows smaller lens diameters while maintaining aperture values for overall compactness.

-ZL Zoom lock mechanism. Prevents undesired barrel extension whilst carrying the camera-lens around, thus protecting the lens.
