lower anti-armor effectiveness (lower anti-armor RoF) for field artillery pieces which had two gunners - one responsible for vertical aiming and another for horizontal aiming - which made these guns difficult to aim at oblique fast-moving targets (like tanks etc).
On the 152-mm s.FH 18, the K1 gunner operated the lateral movement and announced the barrel elevation setting to the K2. The gun had a flywheel mechanism (a rather central mount, on the left side of the carriage) to adjust the elevation, so aiming was even faster than on the leFH 18 (with 2 regular wheels, on the left - K1 - and on the right - K2 -). The Russians captured several of those pieces and highlighted the gun's flywheel mechanism (and the suspension, the low mount design and the recoil damper mechanism - which was a hydraulic one inside a pneumatic one) after the GAU had conducted trials. There's some footage from the NA theatre where you can see how quick the aim could be adjusted.
