Walk-around: Pentacon auto 100 mm f/2.8

The Pentacon 100/2.8 is the final iteration of the venerable MOG Orestor 100/2.8. I took my sample for a spin through some Helsinki parks.

Gallery: Nikkor Ai-s 35 mm f/1.4

I was traveling to Tallinn (Estonia) with some fellow camera enthusiasts. For most of one day, the Nikkor Ai-s 35 mm f/1.4 was stuck to my camera. Feel free to view the results.

Walk-arounds, Galleries and Data sheets

This post details an update to JAPB’s previous policy regarding the types of articles we aim to publish about lenses.

In short we’re introducing a new type of article (the gallery) as well as officially admitting that we feel our time and energy is best used …

Walk-around: Topcon RE.Auto-TOPCOR 100 mm f/2.8

The Topcon RE.Auto-TOPCOR 100 mm f/2.8 is a classic Sonnar formula portrait lens and was introduced in 1965 (although its lineage goes all the way to 1957).
In this Walk-around I take the lens to a sunny day in Tallinn, to find out whether it’s a keeper.

Walk-around: Konica Hexanon AR 40 mm f/1.8

The Konica Hexanon AR 40 mm f/1.8 is a 1980s kit pancake lens. And it’s cheap as chips. But is it any good?
I went on a spring Sunday walk with only this lens to work with.

This update briefly lists all the new articles/pages added to JAPB during March and April of 2025

March 12, 2025

Walk-around: Chinon Auto Zoom 28-50 mm f/3.5–4.5

This Chinon 28-50 is a compact 1980s wide-angle to standard zoom. The focal length range is (IMO) perfect for an urban walk-around.
Knowing I would have two hours to kill in Tallinn (Estonia), I mounted this lens to see what its weaknesses are.

January–February 2025 Update

1-2/2025 has to offer: two new lens mounts, five company profiles, 25 new data sheets, one cold winter walk-around and a deep-dive into the development of a lens over 50+ years. Enjoy.

January 12, 2025

Walk-around: Topcon RE.Topcor 35 mm f/2.8

Introduced in 1963, the Topcon RE 35 mm f/2.8 was the only 35 mm lens in the entire Topcon ‘pro’ line. How did it manage to defend its turf so well?

Topcon UV Topcor 35 mm f/3.5 lens on Topcon Uni camera with paw patrol toy.

May 31, 2024

Walk-around: Topcon UV Topcor 35 mm f/3.5

This little lens with its modest mainline specifications and with its origins in Topcon’s consumer/budget range does nothing to engender high expectations …

Nikon Df, Nikon 50-300 mm f/4.5 and some toy dinosaurs

May 10, 2024

Walk-around Nikkor F 50–300mm f/4.5

November-December 2023 Update

Here you can find all new articles/pages added to JAPB during November and December 2023. My personal favourite of these ≈20 additions is the article discussing the ‘Soviet Nikon’.

JAPB is a website centred on photography and photo gear, with a special interest in using old lenses on modern cameras.

We (currently, I) are not trying to push you to buying new, expensive gear. Instead, our approach is the opposite (in all aspects). Instead we want to help you made informed decisions, and if we can be said to ‘push’ anything, that would be relatively cheap, old gear.

JAPB is non-profit, in fact this is a loss generator. Some day that might change, but we’ll make sure that does not happen at the expense of the audience.
