Sigh... more false blanket statements. Several medium and large format lenses perform as good as, or outperform, Leica 35mm rangefinder lenses, and for sure your Russar 20mm, in absolute terms. Of course, the whole point is that this is not generally necessary, with the larger film area. Also, for the kinds of photography I do most, an adjustable view camera works best - horses for courses... but the propagation of the myth that large format lenses somehow perform poorer than other lenses really bugs me. This has been demonstrated time and again to not be the case. And all good lenses become limited by diffraction pretty soon.
