When i bought my P45+ i tested the two 80s from mamiya and the differences in terms of resolution and sharpness were huge! The old one has something like a veil...a mid grey veil... This consideration it's good also for 35mm and i guess for all the non-digital lenses. They are good, i mean you can work with old style lenses, but the digital design it's tack sharp and you'll find yourself asking if you really need to sharpening...
