Use case + rendering

The 210 G-Claron is the alternative-process portrait + product-macro lens — the most-popular G-Claron focal length among contemporary alt-process photographers. Sharp by f/22 across the field; the dialyte design produces a distinctive rendering character that some photographers prefer for portrait work over the more-clinical Apo-Symmar.

The slow f/9 aperture and dim ground glass are the price for the larger image circle.
