The XA was a rangefinder dressed in a compact camera's body. At first glance, you'd never know it was a rangefinder. And the one reason why people didn't want to own want was because they had no idea what a rangefinder is.
Now we have all see the Pen-S. A ditty little number that could only focus by estimation. You dial in the distance of the subject to your camera and prayed that you had it in focus, very much like the Lomo LCA of course. But this sort of focusing didn't always give you sharp pictures (which is why I always felt that the LCA was overpriced for what it was worth).
Notice that slide films give better contrast and color rendering than negative film. The lens coating on a camera goes some way to give you a hint of more contrast but that is as far as it goes. Most of the rendering work is done by the emulsion on the film and that's why shooting slides is far more rewarding than shooting negative film.
There was one negative film I loved, the Fuji Reala series. But it has since been discontinued owing to the demise of analogue photography in general.
You could still get the Velvia stock, which is a type of Slide film. It's got very good contrast and color saturation.
And the beauty of it all is that in can fit into ANY camera. Film stocks in 35mm comes in a standard cartridge. You can use it in any analogue camera.
