three panes of glass
For a 90mm focal length lens, it’s got f/4, but the aperture could be better. However, many people like this lens, which is made up of three pieces of glass. It actually has excellent optical quality and vivid color contrast. Collectors like it because it was produced in small quantities. This also makes it cost more than the regular version. What makes it special is that it uses more advanced glass than the previous version, with only three pieces, while the previous version had four pieces.
There are 5,947 M-mount lenses and 543 L39 screw-mount lenses. The lenses were made between 1964 and 1968.
High definition, high contrast
The Elmar 90mm f4 3-element is noticeably sharper than previous versions. It’s better than the Elmarit 90mm 2.8 V1 at f/4. The picture is much more vivid than the Tele-Elmarit 90mm 2.8. This lens is really sharp.
