Use with the Leica M8 models is not recommended since the optical properties do not suit for

smaller formats than 35 mm (24x36 mm).

2 The 6 bit lens identiﬁcation bar code (8) situated on the bayonet ﬂange enables the digital Leica M

models to identify the attached type of lens. This information is utilized by the camera to optimize

exposure and image data.

3The Leica M1 does not have a 90 mm bright-line frame.

STRUCTURE OF THE LENS

In the Leica Thambar-M 90 f/2.2, the rotating front part of the lens mount

contains the aperture setting ring (3), the knurled gripping ring for distace

setting (4) and the aperture (3b) and distance scales (4a). The index for distance

setting (5), the depth of ﬁeld scale (6) and a red dot for lens change (7) are

located on the ﬁxed rear part of the lens mount. A 6 bit lens identiﬁcation bar

code (8) is situated on the bayonet ﬂange. It relays lens data to the camera

body so the exposure metering system of digital Leica M models can be calibrat-

ed. The information is also used to custom-optimize image data according to the

respective lens.

USE WITH/WITHOUT CENTER SPOT FILTER

Due to its special optical properties, the degree of soft-focus of the Leica

Thambar-M 90 f/2.2 can be controlled to a certain extent. Without the center

spot ﬁlter (2) supplied, this is done only with the aperture; the scale with the

white values applies in this case. When the aperture is open, the soft focus

eﬀect is very marked; with aperture values of around 9 and higher, the lens

provides its highest contrast reproduction. This is due to the fact that then only

the central area of the lens with the best image aberration correction is used.

An even greater soft focus eﬀect can be achieved with the center spot ﬁlter sup-

plied: Since the opaque spot in the centre of the aperture blocks the central

beam, the image is largely generated only by a ring of beams, and consquently

only with the area of the lens that is primarily responsible for the soft focus

eﬀect. In this case, the aperture scales with the red values applies. The higher

values of the larger apertures (in comparison to those on the white scale) take

account of the light loss through the blocking of the central beam. This scale

reaches only up to 6.3 since the simultaenous use of even smaller aperture

EN openings and the center spot results in dark to black round areas in the middle

of the image. Blocking the central beam also means that unfocussed light spots

are portrayed as bright rings.

ADJUSTING OF THE APERTURE

It is recommended ﬁrst of all to set the aperture with the relevant ring (3) and

only then to adjust the focus, since the aperture scales (3b) are located on the

rotating front part of the lens mount and consequently cannot be seen

completely from above at all distance settings. To protect against accidental

missetting of the distance, you should hold the front part of the lens mount

ﬁrmly when setting the aperture.

FOCUSING

The focus is set by turning the front part of the lens mount on the gripping

section (4).

DEPTH OF FIELD SCALE

The scale (6) on the ﬁxed back part of the lens mount shows the range of depth

of ﬁeld for the distance that has been set. It is read from the relevant line

segments, marked with the aperture values.

LENS HOOD

The lens hood (1) for the Leica Thambar-M 90 f/2.2 is aligned straight to the

lens and then pushed onto its front mount. It can also be put on the other way

round for space-saving storage. In this position, the metal cover supplied can be

put on. For as long as the camera is being carried and used ready for

photography, the lens hood should always remain attached. It provides eﬀective

protection against contrast-reducing stray light and also against damage and

soiling of the front lens, e.g. from accidental ﬁngerprints.

ACCESSORIES

E49 screw-on ﬁlters can be used on the Leica Thambar-M 90 f/2.2. Appropriate

ﬁlters are available from Leica, as are viewﬁnder magniﬁers for the camera that

enable more precise setting of the sharpness thanks to the enlarged viewﬁnder

image. For more details, refer to the Leica Camera AG website: www.

EN TIPS ON LENS CARE

Dust on the outside of the lens is removed only with a soft-haired brush or a

soft, clean, dry microﬁber cloth. We recommend micro-ﬁber cloths (available

from photographic and optical specialists) that are stored in a protective

container and can be washed at temperatures of up to 40°C (without fabric

softener, never iron!). If stains and ﬁngerprints have to be removed, use such a

cloth and clean with a circular movement starting at the center of the lens. Do

not use the type of cloths used especially for cleaning eyeglasses since these

are impregnated with chemicals which can damage the glass used for high

performance lenses. For easy, smooth lens changes, the bayonet has had an

extremely thin coating of grease applied in the factory. With normal use, this

condition lasts for many years, even if the bayonet is wiped with a clean cloth

from time to time. If a degreasing agent is used for cleaning, the grease ﬁlm

must be replaced afterwards. To do this, smear a small amount of Vaseline over

the bayonet with you ﬁnger and rub with a clean cloth.

Important

Make sure not to apply too much vaseline to the bayonet, especially to omit the

lens identiﬁcation bar code (8), because residual grease could otherwise remain

in the recess and lead to further grime accumulating. This could even cause the

code to become illegible and thus interfere with some camera functions in

digital M-models.

In addition to the designation by type, each lens has an individual serial number.

Please note this number in your documents as a safety measure.
