I’ve been away from the world of visual arts for about 16 years, but I’m back with a refueled interest after buying a vintage camera for a minor macro-photography project. This branched out into shots of architecture and various objects, some of which have been clustered into the ‘Objects for an Ideal Home‘ series.

This October (2024), I’ve done some night photography experiments with a Nikon D3 and a Pentax K1.

Pentax 77mm 1.8 Limited Lens
With an odd focal length of 77mm and an unconventional f-stop value of 1.8 – in comparison to traditional values such as 55/50/80/85mm and 2.0 or 1.4 – we find ourselves in the company of the Pentax 77mm f/1.8 lens, the brainchild of Japanese lens designer Mr. Jun Hirokawa, a designer who clearly marches to… Continue reading Pentax 77mm 1.8 Limited Lens
Shooting with a Nikon D3 in 2025 ~ Photos & Thoughts
In December 2023, I ‘side-graded’ from a Pentax K5 to a Nikon D3. With the K5, I used either a 35mm macro limited lens or a 77mm 1.8 limited. The K5 had deteriorated gradually. First thing that stopped working, was the sd card slot where the cards got stock, which meant that only the USB… Continue reading Shooting with a Nikon D3 in 2025 ~ Photos & Thoughts

When going through the photos in my blog post on the Leben CS-600 amplifier by Japanese Leben Hi-Fi Stereo Company, I noticed that the damper tube in this photo: was marked 6DN3, which I, funnily enough, hadn’t noticed before.
