OLJ LUX — A New Approach to Protecting Classic Lenses Sometimes, a new product begins with a very simple question. When we developed the OLJ Type 5 lens hood for classic Nikon rangefinder lenses, including the W-Nikkor.C 2.5cm F4 LTM and W-Nikkor 3.5cm F2.5 LTM, our primary objective was to create a beautiful, durable hood that would protect these remarkable vintage lenses for generations to come. Both lenses use a rather unusual 34.5mm filter thread. We initially considered

From a 1950s Japanese optical masterpiece to a new photographic adventure Some lenses are made to take photographs. Others become legends. The ZUNOW 5cm F1.1 belongs to both worlds. Produced in Japan during the 1950s, the ZUNOW was among the fastest photographic lenses of its era. Its remarkable F1.1 maximum aperture, distinctive optical character, and rarity have made it one of the most fascinating lenses for collectors of vintage Japanese optics. For me, however, collecting

Some lenses enter a collection and immediately feel permanent. Others take a little longer to reveal themselves. My Leica Elmarit 28mm F2.8 Version 1 belongs firmly to the second group. I purchased this lens from Meteor Hong Kong on June 24, 2016, for HK$14,000. What makes that purchase particularly memorable to me is that Old Lens Junkies founder Yoshiaki Kubota was with me when I bought it. Many years later, however, I actually took the lens to MK Kamera in Hong Kong with t

The Nikkor 5cm F1.4 is a beautifully compact classic rangefinder lens. Its small size is part of its charm, but sometimes I wanted it to have a little more presence when mounted on the camera. That is where the OLJ Type 3 and Type 2 hoods come in. By mounting the Type 3 hood on the Nikkor 5cm F1.4 and then adding the OLJ Type 2 hood, the lens takes on a completely different appearance. The lens itself does not change. Its optical performance remains exactly the same. What cha

I do not own an original Zunow filter, but my Bell & Howell S L39 54.5mm C filters fit three of my four Zunow 5cm F1.1 lenses perfectly. The Bell & Howell filters have a 54.5 mm × 0.75 mm mounting thread, which strongly suggests those three lenses use the same size. ​ If you have one of these Bell & Howell filters with damaged glass or a color you would never use, you can remove the glass and use the empty frame as an adapter. Its front thread is 55 mm. I attach a 55-to-62 mm

Recently, we received an inquiry regarding the use of a 67mm filter on our Type 2 lens hood. Our hood is fully compatible with any standard 67mm × 0.75 filter thread, and using a 67mm filter is perfectly acceptable. 67mm x 0.75mm thread filter on Type 2 lens hood However, we recommend mounting a 62mm × 0.75 filter directly onto your Nikon lens. This allows the filter to remain in place to protect the front element when the hood is reversed for storage — a feature incorporate

There is something deeply compelling about an object that reveals what it truly is. Crafted from solid brass and left in its natural state, this edition celebrates material honesty and vintage character. It does not rely on paint to define its identity. Instead, it allows the metal itself to speak — warm, dense, and unmistakably mechanical. Unlike painted finishes that remain unchanged, the Natural Brass Edition evolves. With time and use, the surface ages gracefully, develo

At Old Lens Junkies, we enjoy exploring new possibilities for our original lens hood designs, particularly when they can complement other legendary photographic lenses. The OLJ Type 2 was originally developed for the remarkable Nikkor-N 5cm F1.1. However, we were curious to see how its distinctive brass construction and classic appearance would complement another extraordinary lens — the Leica Noctilux-M 50mm F0.95 ASPH. An Interesting Experiment Using an E60-to-62mm step-up

A Small Difference with an Interesting History When we first explored accessories for the legendary ZUNOW 5cm F1.1 in 2023, we believed that the earlier versions generally used a 55mm filter thread, while later examples used 54.5mm. Further research has shown that the story is considerably more complicated. Through examining surviving ZUNOW lenses, comparing serial numbers, and studying their mechanical differences, Old Lens Junkies has discovered that filter thread diameter

The OLJ Type 2 lens hood was developed specifically for the legendary Nikkor-N 5cm F1.1, combining classic craftsmanship with an innovative, patented design. Precision-crafted from solid brass and finished in elegant black paint, the Type 2 weighs approximately 198.73 grams, compared with just 23.523 grams for the original plastic Nikon hood. Its substantial construction reflects our commitment to durability, quality, and the preservation of exceptional vintage photographic e
