I have a Miranda D and some of the accessories and lenses.
M42 adapter
Chest level finder
The lenses are good by 1960 standards. The 1.9/50 has a very vintagey feel about its rendering quality.
The 2.8/50 gives a classic tessar type look.
I have a 2.8/105 T mount lens which is also surprisingly good - here at f4.
The perks of the Mirandas are that they are pretty quiet (by 1960s SLR standards) they are pretty small, they have interchangeable viewfinders, and there are adapters for M42, Nikon, Exakta and some other mounts that work with infinity focussing, although the diaphragm operation will be manual.
The operation is very smooth, the build is substantial, but the fit and finish is only average at best really. Certain models are also known for finicky reliability. The nickname "poor man's Nikon F" is pretty fitting really.
I quite like my Model D, but an F or a G or a later Sensorex are probably better as users as they can take more modern lenses - the D is stuck with PAD lenses (pressure activated diaphragm, exakta style) of which only 28mm to 135mm focal lengths were made - or preset T mount lenses.
