- The pictures were taken with a Sony Alpha 7 digital camera. The lenses were designed to be used with film cameras. So some issues, you see here, aren't issues with film cameras. The Alpha 7 shows a higher resolution than Velvia 50 film, so some issues are just hidden by the film grain, others are caused by the problems digital sensors have with light rays hitting at an angle.
- The pictures are out of camera JPEGs, the crops show full resolution (100%). The camera settings were zeroed. So some of the issues, like vignetting or CAs, can be fixed (more or less) easily in post processing.
- The crops represent a print 50cm (20in) wide, printed at 300dpi. Keep this in mind, when judging the images.
- Lenses perform within their specifications, so differences between samples are common. These are pictures taken with my lenses, and they are old. So the pictures show only the performance of my samples. Other samples may give different results.
