Carl Zeiss Jena Triotar 85/4 and Nikon Z5 – An Empirical Field Test
This empirical field test of a fairly well-preserved CZJ Triotar 85/4 lens confirms its well-known performance, although a final judgement needs to wait the lens to be serviced by master Adriano Lolli in order to clean veiled glasses. At F4, central sharpness is moderate yet usable, with a lack of microcontrast. By contrast, the corners are softer. Flare resistance is suboptimal by modern standards, while colour rendition is accurate enough, although robust tweaks are needed in post-production. This photo of the Leica store display in Via dei Due Macelli, Rome, is a flare torture test. The bright, emissive Leica sign against a dark background, plus additional reflections and obstructions, creates…

Pentacon 50/1.8 and Nikon Z5 – An Empirical Field Test
This field-test is, as the others I have published here, absolutely subjective, empirical and lacking any scientific basis. Since I couldn’t find anything interesting to photograph I decided to take pictures more focused on showing the lens features rather than creative or interesting subjects.This is why each photo was taken wide open and at F8. Moreover, to make a comparison possible, I also shot some of the mannequins featured in the Zeiss Biogon and Minolta 35mm lenses posts. Finally, as far as post-production is concerned, I used the RGB curves to set the black and grey tones, and tweaked micro-contrast.

Zeiss ZM Biogon 35/2 and Nikon Z5. An Empirical Field Test
This is an empirical field test of the Zeiss ZM T* 35/2 Biogon lens mounted on a Nikon Z5. As with all my technical tests, this one doesn’t deal with MTF, coma, fall-offs, etc., as I’d rather focus — pun intended — on the results.

Minolta MC W Rokkor-HG 35/2.8 and Nikon Z5 – An Empirical Field-Test
This is another episode featuring a Nikon Z camera and a vintage lens. This time, I’m using the Minolta MC Rokkor-HG 35/2.8, which I recently took out of the cupboard where I keep my old manual lenses. The following shots have all been taken wide open, in no particular order and are intended to demonstrate how the lens performs in different conditions. The Z5 was instructed to use a flat picture profile and the photos were post-processed to the final results should not be considered as a true ‘rough’ example of the lens’ character.

Leitz Summicron 50/2 and Nikon Z5 – An empirical field test
A casual stroll around the Trevi Fountain gave me the chance to experiment with an unusual combination: an old Summicron 50/2 and a relatively new Nikon Z5. The opportunity materialised in a photo of one of the crowd-control team members regulating the overwhelming flow of tourists and ensuring that none of them were engaging in vandalism or pranks. In short, I am very pleased with the results. I owned a Leica M9 (which I happily sold) for a few years , and I can’t actually say that I miss it. My only regret was that I could only use my lenses on APS-C mirrorless cameras, such as Fujis. I knew…

Knowledge in the Atelier (or: The First Shot of 2026)
This is my first attempt at taking a photo in 2026. I took it late one afternoon in my hometown, where I’m staying for a few days. My aim was to continue experimenting with the Nikon Z5 and various manual lenses. This time, I used the Nikkor 35 AF-D F2 — an old lens that is still very capable. Technically, the AF-D has autofocus. However, since I am using a ‘dumb’ adapter, I can only use the lens manually.
