The one big improvement with many of the newer computer designed and manufactured lenses is sharpness in the corners. But when it comes to the full image at F5.6 or F8D many of the older lenses are equal to today in most respects. Of course, with digital sensors the coding change does help control reflection off the sensor surface. That’s what I’m told. But better old lenses under controlled lighting … I’m having no problem. Just keeping away from the sun flare.
That said, the newer computer designed zoom lenses are sharper across the range. But your classic prime lenses, no sense and not using them. They’re good. I did it a couple months ago with an old Konica AR lens, 57 mm f1.4. Optical design is everything, whether computer made or mechanically ground. That lens serves as evidence to me that rendering of the image is far more important than simple resolutions. The Konica has a much flatter field than anything else I have and that focal length range, including the Pentax. In short, there are advantages to some of the newer lenses but as you have found many of the classics remain the equal of the newer models. For all practical purposes. -- %(real_name)s Pentax-Discuss Mail List To unsubscribe send an email to pdml-le...@pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
