The color version of yesterdays. While not intended as a formal test, it illustrates something to test that took for granted decades ago - the softness of the vintage lens. It could be my vision and need to focus, but split matching focusing shouldn't be vision dependent. I am consistently seeing softness, in this case with the Canon 50mm f1.8, compared to todays lens, in this case the 35mm Sony/Zeiss f2.8. While no EFIX on film, adjusting ISO (400 vs 200) and known shutter speed on Canon, estimating aperture was f2,8 or 4, where the 35mm lens was at f8. Understandable that the background and gator foreground would be out of focus in the B&W, but the well focused print on shirt would be on the same plane as the head that was relatively soft. Time to do a controlled experiment with closely matching focal lengths. Also now making sense of why many of the slides from back in the day are soft compared to current, and not solely a 'deterioration' excuse.
