Canon, normal and “short back focus” (right) lenses.
In a series of EF-S: EF-S 10-22 mm f / 3,5-4,5 USM “lens specially designed for serious work with digital SLR cameras Canon EOS 20D and EOS 300D.
“Supports E-TTL II automatic flare system.
The same feature is the lens EF-S 17-85 mm f/4-5, 6 IS USM.
And we have already mentioned EF-S 18-55 f / 3,5-5,6, which applies only complete with the EOS 300D.
This is a “Lenses DX, which were implemented earlier types of lens technology, but in doing so offer a more effective technical capabilities for users of digital SLR cameras.
The main feature is that the DX lenses create a smaller image circle, not covering the area of the frame on the film 135, but sufficient for digital cameras with a matrix of 24 x 16 mm.
The matrices of such size are installed in the cells D1, D1X, D1H, D100, D2H, D2X, D70.
The result is a lens with a more compact and lightweight construction.
Although mechanically DX optics compatible with full-frame SLR, Nikon does not recommend using DX Nikkor lenses with 135 format cameras.
In a series of DX Nikkor: DX Fisheye 10,5 mm f / 2,8 G.
The world’s first full-frame fisheye lens designed specifically for digital SLR Nikon D1X, D2H, D1H, D1, D100, D70.
The angle of view of 180 degrees.
AF-S DX 18-70 mm f / 3,5-4,5 G.
AF-S means that the lens is set silent focus motor, not a shortened posterior segment.
AF-S DX 18-70 mm f / 3,5-4,5 G
DX 12-24 f / 4 G IF-ED AF-S.
As noted on the site “the world’s first lens with the small size of the resulting picture is optimized for DX-sized sensor.
Olympus optics designed specifically for the “digital” standard “4 / 3, so this is really lenses for digital SLR cameras,” without regard for film cameras.
All lenses ZUIKO Digital feature near-telecentric construction to the light projected onto the sensitive elements of the matrix at right angles.
This prevents deterioration of the edges.

Not all digital SLRs have a matrix, reduced compared with the frame 35 mm film.
There is a full-frame and with a coefficient of less than 1.5, but the big one.
Bet only on the APS format is not reasonable, especially the most renowned producers of optics.
So while others point out how good their lens with a reduced field, Pentax lenses create contrast, calculated under a number, but having opaque field sufficient to photographers with a full-frame cameras have not noticed the deterioration of the quality of the image-edge sharpness.
We have a Pentax as lightweight (under the small matrix), and full-frame digital lenses.
And this despite the fact that digital SLR cameras, the company is not so much (as long as 2, but first appeared in mid-2003).
Reserve for the future.
For cameras with a small company produces a matrix line optics PENTAX DA.

For cameras with full-frame matrix – PENTAX-D FA.
These lenses are designed specifically for digital SLRs, but their field of view of covering the same field 35-mm SLR cameras.
The first series products SMC PENTAX-D FA – macro lens with improved optical design.
As noted in the press release: “Know-how to minimize the undesirable aspects when working with digital SLR (such as” spurious illumination and vignetting images).
The new lenses provide the maximum increase 1X (full size), allowing you to achieve impressive, clear Macro.

Sigma produces lenses for many cameras, including specially designed for digital SLR – Series EX-DG.
Such optics, as the producer, features (usually) more uniform distribution of brightness on the field frame.
It is suitable for full-frame film and digital cameras.
DC Series is specially designed for cameras with matrices of size close to the APS, so when you install the usual full-frame on the image will be observed vignetting.
