Today, I'm presenting the Leica Summarex 85mm f/1.5 lens, a rare and fascinating piece of equipment. Produced between 1943 and 1960 with only about 4,400 units made, it's not easy to find one in good condition. Originally designed with an LTM 39mm screw mount, I've adapted it with an M mount to use with more modern cameras. • The lens boasts a robust construction typical of Leica, though it doesn't entirely match the user experience we're accustomed to today. It's a heavy lens, and most of the examples I've taken are at full aperture to showcase its capabilities. Featuring a 17-blade diaphragm that maintains a nearly circular shape at all apertures, it delivers an exceptional, soft, and creamy bokeh. • I tested the lens on a Leica SL2 camera, a 47-megapixel model with a sensor designed to work well with older lenses. The sensor's micro-lens array helps render photons coming at strong angles more effectively, similar to film. While this may not significantly affect an 85mm lens, it provides an ideal platform for testing. • In high-contrast areas, the lens produces a distinctive halo effect, especially noticeable around bright subjects against darker backgrounds. This characteristic adds an interesting look and contributes to the lens's unique rendering. The color reproduction is excellent, adding softness and warmth to scenes while remaining true to the real-life colors. • Geometry-wise, vertical and horizontal lines are rendered accurately with no significant distortion, impressive for a lens over 50 years old. However, the lens is prone to flare, particularly in situations with strong light sources, creating semi-circular effects or other artifacts. While some may find this undesirable, it can add character to photographs if used creatively. • In low-light situations, such as night scenes or indoor settings, the lens performs well, capturing detailed and atmospheric images. It handles artificial light and high-contrast scenes effectively, maintaining detail while adding its characteristic softness. When photographing subjects like the Northern Lights or distant landscapes, the lens provides a painting-like effect with precise rendering of stars and subtle details. • Overall, using the Summarex 85mm f/1.5 lens is a pleasure. Its combination of softness and precision, along with its unique rendering characteristics, make it a fascinating tool for photography. If you have the opportunity to use or borrow one, I highly recommend it. • A note on the lens's design: it was intended to be part of a practical kit, including the original lens cover and a flare protection hood. The only way to attach the original cover is to reverse the hood, which may not be as practical by today's standards. Additionally, due to its weight, the lens comes with a tripod attachment and retains its original LTM 39mm screw thread. • want to support the channel ---- • 1 - subscribe to the channel, like and activate alert • 2 - get the iOS apps https://appstoreconnect.apple.com/app... • 3 - grab my books • Serial Matnum 2023 07 https://www.blurb.com/b/11665639 • Serial Matnum 2023 06 https://www.blurb.com/b/11641364 • 3 - comment, respond, propose subjects for future episodes • yay! :) • direct links to playlists ---- • http://aishit.net • http://voncam.net • fast links http://zand.li • http://zdrilx.com for the music
