The Braun SR2000 is somewhat confusing for people. It is marked on the pentaprism as "BRAUN" and on the front, under the rewind knob, as SR2000. So most people refer to it simply as the Braun SR2000.
It was made by Phenix (NOT Phoenix), and was sold under other names. It is the exact same camera as the Phenix DC901 and DC20.
But there were three different versions of the Braun SR2000. One was made for Minolta Rokkor lenses and on the front of the camera, next to the lens mount it is marked "MD".
The Braun SR2000 was also sold with a Pentax K mount in a SLIGHTLY different body style, with SLIGHTLY different features. Like the Braun 2000 MD, that model is also often referred to as simply the Braun SR2000 -- but sometimes as the Braun SR2000 PK because it is marked next to the lens mount as "PK". Needless to say, this leads to some confusion. There were other Pentax K models of the Braun 2000 PK, as well, such as the Promaster 2500, the Hikari 2002, and the Vivitar V3800N.
The Braun SR2000 was also sold with a Contax/Yashica mount in a SLIGHTLY different body style and with SLIGHTLY different features. This version is only referred to as the Braun SR2000Y because it is clearly marked as such. Why it was not marked as "SR2000CY", or why the "Y" was not placed next to the lens mount, we will never know.
But the Braun SR2000 is not the only Chinese-made SLR camera with a 1/2000 top speed. There were several others -- all mechanical, metal, vertical shutter. The ones with a Minolta lens mount are listed on my website:
