M S Optics ISM 50mm 1.0

Recommended Posts

Advertisement (gone after registration)

The MS Optics 50mm 1.1 Sonnetar is very fast, noted on the description sheet as being f1.16.

Now the MS Optics ISM 50mm 1.0 is available in M mount at only 178 grams.

It is noted as f1.05 on the description. So it is only somewhat faster than the Sonnetar. 

If one already has a Sonnetar 50mm, not sure if they would be interested in this lens.

With Gauss type lens it does not have the soonar qualities of the former, but apparently also not the tricky coma adjustment ring.

16 rounded aperture blades.

Looks interesting though for digital or film,

Description says « To make a large aperture lens requires thick, heavy high refractive index glass, but I deliberately used thin and light high power optical glass, and reduced the size of the rear group to meet the size requirements, thus successfully designing an ultra small and light full frame Leica M lens with a length of 40mm, diameter of 50mm, and weight of 178g ». Wrong translation you think?

Yeah, looks way too glowy and over-coma-tose for me at f1.
