I've a great affection for Minolta, though born from retro appeal because I am not old enough to have seen their best stuff first time around. I'd love to know more about how the company operated during the 50s to 70s. Their 1970s models, the X1, XE, and XD seem technically really exciting but don't appear to have held the attention of the professional market - unreliable, lacking something important, too expensive, or is it just about the brand? I gather that few XEs and XDs (the X1 is too rare to count) have made it to the present without some reliability problems, but that's not so surprising given the time span. Briefly - before the pandemic arrived and took away most of my spare time - I had a hobby of repairing the Minolta SR-1, the earlier purely mechanical camera sold from 1959 to 1971. The SR-1 is interesting because it was Minolta's ongoing "entry level camera" rather than a single specific design - they used the same designation for at least five different cameras underneath, in the course of its sales life. They're surprisingly different under the covers, and you can track a bit of what was going on elsewhere in their product line through them. So the SR-1 model A is a solid mechanical design, complicated but not too difficult to understand and repair. Model B is almost identical on the outside, but mechanically quite different underneath and with some odd design decisions that might have been a weak attempt at cost-saving or possibly about synchronisation with another product (this is the sort of thing that makes me wish I knew more about the company). I haven't seen a model C and am not totally sure it exists. Model D I think is a bit of a mess, combining the mechanicals of earlier models with various new features (primarily the lightmeter, though support for it existed in the model B even though the accessory didn't). And model E is a serious clean-slate rebuild that is mechanically simpler but less accessible and far more like what competitors such as Pentax were producing at the time. I use an SR-1 model A as my usual film camera, it's a bit big and heavy and the winding lever carves a big channel in your forehead but it's so beautiful and satisfying to use. (I wrote a couple of blog posts about the SR-1 models A and B, at https://thebreakfastpost.com/2019/12/21/notes-on-the-minolta-sr-1-model-a/ https://thebreakfastpost.com/2019/12/21/notes-on-the-minolta... and https://thebreakfastpost.com/2020/03/12/notes-on-the-minolta-sr-1-model-b/ https://thebreakfastpost.com/2020/03/12/notes-on-the-minolta... - I wanted to bring it up to the D and E but reality intervened.)
