After two days shooting with the Yashicamat 124 and it's fixed meter, and a trip to one of the Ancient Seven Wonders of the World, every reading matched my Luna Pro to within ½ a stop, and when the Yashica differed it was always towards ½ over exposing which is perfect for my B&W work. The negatives are perfect.
For the first time in years I missed a wide angle lens for the square format and, I needed to use a 55mm, I had one for my C33 & C3 in the mid 70's but it & the camera's were stolen in the early 80's.
