The only reference I can find to the use of the telescopic sight is this reference from page 294 in Martin Pegg's book on the Hs 129:

When the cannon was fired, the muzzle blast and recoil caused a momentary loss of speed in the order of 10kph, but the few Hs 129 B-3s which were used in combat generally created a very favorable impression with the pilots who flew them. However, one criticism made by Franz Oswald, who flew a machine delivered to 13.(Pz)/SG 9, was that the ZFR 3 B telescopic gunsight made target acquisition difficult.
