And i'd actually like a source of soviet optics being "bad" instead of a video and some saying that russians always miss the first shot.
Hell, even the americans admitted that the optics of the t-34 were superior to anything they had. And they were rather critical about the t-34. Mainly because the early t-34 models weren't exactly reliable.
"The gun sights and range finding for the F-34 main gun (either the TMFD-7 or the PT4-7[52]) were rather crude, especially compared to those of their German adversaries, affecting accuracy and the ability to engage at long ranges.[53] As a result of the T-34's two-man turret, weak optics, and poor vision devices, the Germans noted:
T-34s operated in a disorganised fashion with little coordination, or else tended to clump together like a hen with its chicks. Individual tank commanders lacked situational awareness due to the poor provision of vision devices and preoccupation with gunnery duties. A tank platoon would seldom be capable of engaging three separate targets, but would tend to focus on a single target selected by the platoon leader. As a result T-34 platoons lost the greater firepower of three independently operating tanks.[54]
The Germans also noted the T-34 was very slow to find and engage targets, while their own tanks could typically get off three rounds for every one fired by the T-34."

The T-34 proofed to be a very clumsy vehicle. The only advantage it had, was it´s availability. It was always there. Engaging German armor was another thing though.
