The Tiny All-rounder: Leica Elmar 90mm f/4.0 3-element Review

圖片
Table Of Contents ✓ Introduction Leica's first Elmar 9cm (90mm) f/4.0 was introduced in 1930. The lens construction was very similar to that of the Zeiss Tessar, with the main difference being that the Elmar had the aperture positioned in front of the second lens element. After several cosmetic changes, the optics of the popular Elmar 90mm lens remained unchanged until the early 1960s. In 1962, a new version of the Elmar 90/4.0 was released, designed by Walter Mandler in Canada using newly invented rare-earth glass, which elevated the performance of this classic lens to another level. Lens Versions There is only one version. It comes with either a Leica M mount (11830) or a Leica screw mount (11830). Leica Elmar 90mm f/4.0 3-element M mount Lens Specifications Lens mount: Leica M Focal length: 90mm Aperture adjustment: f/4.0–f/22 (with half-stop clicks) Number of aperture blades: 10 Minimum focus distance: 1 meter Filter size: E39 Hood: IUFOO or 12575 Weight: ~220g Leitz Sales...

One of a Kind: The Nikon EL-Nikkor 50mm f/2.8 Enlarger

圖片
This is a 6 elements in 4 groups enlarger made by Nikon since the mid-50s. The design of this lens is pretty uncommon: the front part is a 1/2 double gauss while the rear part is a 1/2 plasmat.The reason for such design is mentioned on Nikon website: During development of the lens, a German optical manufacturer secured the patent for its basic design. Nikon (formerly Nippon Kogaku K.K.) was forced to incorporate methods that did not violate this patent into its design. There were numerous restrictions to overcome before Nikon could complete its optical system. At wide open, the lens is not as sharp as I expected. Stopping it down to F4, the overall contrast is improved significantly. Here is a sample taken 2-3 meters apart at wide open and at F4. EL-Nikkor 50mm f/2.8 @F2.8 EL-Nikkor 50mm f/2.8 @F4 Since this lens features straight aperture blades, it is expected the sunstar will be nicely defined when stopped down. The lens also works well as a landscape lens when stopped down to F...

Road to perfection : Voigtlander Ultron 75mm F1.9 SC Leica M mount

圖片
A modern, fast 75mm lens with a vintage feel in Leica M mount. This lens is only slightly heavier than the Heliar 75mm f/2.5, yet it is nearly one stop faster. Table Of Contents ✓ Lens Version There are two versions of this lens. One is MC (Multi Coated) with a matte black finish and one is SC (Single Coated) with a black paint finish. The lens being reviewed is the SC version. Lens Specifications Mount: M-Mount (VM) Focal length: 75 mm Aperture: f/1.9-16 Optical construction: 7e/5g Aperture blades: 12 Minimum focusing distance: 0.5m Weight: 290g Filter size: 49mm Handling The focus ring operates smoothly and is well damped. The aperture ring clicks with half-stop clicks. Build quality is excellent. Lens Sharpness On a Sony A7RII, this lens shows pretty good resolution from wide open at the center. To get corner-to-corner sharpness on the A7RII at far distance, it will require stopping down to f/4 to f/5.6. At close distance, this lens becomes softer than at portrait distance. Voig...
