I have a brace of them, EE, Sensorex, RE, and the line of EE lens from 25 to 300. Problem with EE is that shutters are prone to failure, the EE lens will not work in all speeds on non EE bodies. Sensortmate and EE had the sensors on the mirror, you can see a cross patch, problem is that over the years the mirror slap is not good for the wiring that connects the sensor to the body. On the positive side, Miranda designed nice lens. Miranda was bought by an American Company AIG which owed Soligoar, had an in house lens team, then lens were build by 3rd party. At the very end of AIG there was some talk that Miranda was making lens as well. In addition from I understand that they used proven designs by other companies. I have a 135 3.5 Petri that seem almost identical to a Miranda 135. The lens mount is a duel mount, bayonet and a 44mm screw mount. I have seem 3rd pary 400mm in 44mm screw mount. The longest banded Miranda I have is a 300 mm, nice lens very sharp. The Miranda zoom was one of the best of the time. Miranda got very good reviews in Modern and Popular Photo. The last Miranda the Dx killed the company, what a mess, I have 3 none of which work. Used 4 batteries, was not EE, but would work with EE lens as could the bargain body the RE. The Senormat and EE had interchangeable viewfinders, earlier models like the G had the option of different focusing screens. I shoot with a working EE and non metered body, and use the lens on a Sony 3000. Overall they have held up better than say Petri not even close to Pentax, Minolta, or Canon, or of course Nikon.
