Grease-free polarizing filter for easy rotation | Easier to attach due to new varnish technology | Durable and robust due to brass mount | For all lenses with front thread | Ideal for super wide angle to telephoto lenses | Made in Germany Coating: MRC nano Diameter: 37, 39, 40.5, 43, 46, 49, 52, 55, 58, 62, 67, 72, 77, 82, 86, 95

The maximum polarization effect is achieved in landscape photography when shooting at an angle of 90° to the sun. For an even effect in the picture, and because of uneven skylight polarization, your focal length should not be less than 28 mm in 35 mm format.

The Mitutoyo outside micrometers series 103 features either a ratchet stop or friction thimble that applies constant measuring force on a workpiece for exact repetitive readings. Available in metric and inches. The Mitutoyo outside micrometer is ideal for measuring metal and non-metal workpieces. A ratchet-stop mechanism on the 103-135 provides uniform pressure on a workpiece for precise, repeatable measurements. The friction thimble models allow for constant-force measurement for single handed operation.

B+W polarizing filters are circular polarizers which are compatible with nearly all modern cameras when beam splitters are used in the light path for TTL exposure metering or autofocus. Exposure errors are therefore avoided. The multiplying factor with HTC is 2 to 3, which is equivalent to 1 to 1.5 f-stops. Other polarizers up to approx. 3 stops. Often regarded as the most important filter for photography.

Generally speaking, with the help of a properly oriented polarizer, reflections can be completely suppressed in an ideal situation. Here, the ideal situation means that the lighting and shooting angles are almost the same and correspond to the angle of maximum polarization, usually 30° to 40°.

Radiant white clouds against a deep blue sky or the deep colors of fall foliage don't happen by chance. B+W polarizing filters (polarizers for short) augment the purity of the intrinsic colors and increase color saturation and are among the most important filters for analog and digital photography.

Because the filter mounts rotate, the polarization effect can be visibly controlled in the viewfinder or on the monitor display. Another effect of the B+W polarizer is to reduce reflections from non-metallic surfaces such as water, glass, and glossy paint. Objects and people behind surfaces such as shop windows and car windshields become visible again – a fascinating image enhancement without image processing!
