Summicron M 35mm 6-element wide-angle lens type Summicron with Leica M mount.
The 6-element lens is the second generation of Summicron for the M-type Leica, and can be divided into early and late models, mainly due to differences in lens barrel.
The lens introduced here is called the late 6-element lens, and 15,620 were produced between 1971 and 1979.
The difference between the early model and the latter model is the appearance, such as the presence of corners to assist in the rotation of the aperture ring.
This lens does not support modification to add a 6-bit code for lens recognition because the structure of the lens mount metal fittings is old.

The soft depiction produced by this lens (possibly due to the fact that the model I own is a little cloudy) is emotional, and I think it’s the lens to turn to if you get tired of modern lenses.

Summicron M has been released in unique lenses, including the legendary 8-element lens, the modern 7-element lens, aspherical lens, and APO lens.
This lens, commonly known as a 6-element lens, is a bit plain compared to other Summicron M 35mm lenses.
The late 6-element lens has a simple, smooth exterior with the exception of the protrusion on the focusing lever, and is a suitable size to match the M-type Leica, making it a good match for the macho early digital Leica M-type cameras.
The lens I have is made by Leitz Canada, serial number 266xxxx, manufactured in 1973.

The official compatible hood is called IROOA, which is popular for its unique trumpet-shaped appearance, and many compatible hoods are made.
The hood in the photo below is a Safari color compatible hood sold at Mapcamera on the left and a compatible hood of unknown maker on the right. Both hoods have a double hook and can be reversed, but the lens I own cannot be reversed because the focus lever interferes with the reversed hood.
In addition, UN releases many other classic camera compatible products, and recently we have seen many hoods made in China.
