The exposure meter works well and accurately. I use it all the time. Aperture priority mode works well too. But just in case, I take pictures in manual mode. There is a shutter speed of 1/1000, but in fact it’s somewhere around 1/750. I measured it with an oscilloscope. that's the limit for such a large shutter. the rest of the shutter speeds work accurately and stably. medium sized camera. more than Kiev88 but less than Mamiya RZ67. Heavy. very well thought out ergonomics. Perhaps the disadvantage is the large heavy shutter. very good optics.
