In size, weight and appearance, the HC 3,5/50-II is identical to its predecessor, yet its cross-section shows that it has been completely reconstructed, with 11 lenses in 7 groups. The aim was to increase the performance of this all-round, wide-angle lens. The result is a higher resolution that captures the finest details of a motif, with a more uniform performance across the whole image area, that ensures an even more dependable and better result than its already powerful predecessor. The HC 50-II also shows improvements in the important close-up range, where performance results are even greater than before.
