Angarsk: 11 views from 1956 (and 2025)

This is a small postcard titled "Виды Ангарска" (Views of Angarsk, 11 photos) from 1956. Also see another postcard (10 photos) from 1956.




The views themselves are tiny, about the size of a postage stamp, so the resolution is low.

I've also included similar views that I took in June 2025.

Disclaimer: My photographs are nothing more than a documentation of reality.

Suzuki AGS

The Suzuki AGS  (or 5AGS/6AGS) is a five/six-speed Auto Gear Shift transmission. Based on a manual transmission, it uses an electro-hydraulic actuator for automatic gear shifting.




A notable feature is the Park (P) position of the gear selector (see 1 and 2), which makes the AGS appear to the driver as a conventional automatic transmission.

Since 2014, it has been a low-budget option. However, it later became part of Suzuki's "strong" hybrid system.

Overall, I don't like the AGS. It combines the disadvantages of all types of transmissions. Thankfully, there are no AGS transmissions in new JDM cars anymore. This also means that there are no strong hybrids for JDM. JDM strong hybrids based on AGS have been replaced by mild hybrids based on CVT.

Pentax Q 04 6.3/7.1 Toy Lens Wide: Samples [1] - 1/2.3" - f/7.1

Camera: Pentax Q (1/2.3", 12MP)

Once again, I'm having trouble focusing. The image quality is specific. There is also noticeable barrel distortion.

Carl Zeiss Jena Tessar 40/4.5 (M42x1): Non-retrofocus lens

The Carl Zeiss Jena Tessar 1:4,5 f=4cm (40mm f/4.5) with M42x1/45.5 mount.




Despite its focal length being shorter than 43 mm, it was designed as a non-retrofocus lens for SLR cameras. Because of this, it has a rather protruding back.




According to the serial number, the lens was manufactured in 1949.

The Tessar 50/3.5 (on the left) and the Tessar 40/4.5 (on the right):

Suzuki Every [Wagon]: Automatic transmissions

The DA17V/DA17W Suzuki Every [Wagon] (2015-present) can be equipped with one of the following types of automatic transmission: 4AT, 5AGS (Auto Gear Shift, AMT, for the DA17V Every only, until 2024), or CVT (since 2024).




One simple way to determine the type of automatic transmission is to look at the gear selector (as with the Alto). All three types have the conventional symbols P-R-N-D, but there are some differences.

1. The 5AGS has +/- M symbols that stand for manual gear control.




2. The 4AT has 2 and L symbols indicating the gear shift limit positions.




3. The CVT has an L symbol, but not a 2 symbol.

Calibrite ColorChecker Classic Mini

The Calibrite (formerly X-Rite) ColorChecker Classic Mini.



This small, 63.5 x 109.0 mm target is the most affordable option with 24 patches (by Calibrate). I'm going to use it to create DCP profiles for use in ART.

Mitakon [Zhongyi] Creator 35/2: Samples [1] - FF - f/2

Camera: Sony a7c (FF, 24MP)

Like its sibling, the Mitakon 85/2, this lens produces a smooth background blur. However, its other qualities are questionable.

Pentax Q 04 6.3/7.1 Toy Lens Wide

The Pentax Q 04 Toy Lens Wide (6.3mm, f/7.1) is another lens from the so-called "Unique Lenses" series for Pentax Q cameras. This is the second lens from this series that I have purchased for my Pentax Q, after the Q 03 Fish-Eye. On the Pentax Q (1/2.3"), it is equivalent to a 35mm lens.




The Q 04 is slightly smaller than the Q 03 Fish-Eye but slower (f/7.1 vs f/5.6).

It is an electronic lens with manual focus. It lacks a built-in leaf shutter and aperture control. Therefore, it behaves similarly to that of a manual focus lens with an adapter, with a few exceptions. First, a Pentax Q camera saves EXIF data with lens information (including the permanent f/7.1 aperture value). Second, a Pentax Q camera recognizes the focal length (6.3mm) for the sensor-shift image stabilization (SR).

The focusing ring is mechanical, but overly sensitive. There is no distance scale, and the ring rotates far past the infinity (which is also unmarked). The depth of field is large, focusing is difficult.

The lens has 4 elements in 3 groups. Since the flange focal distance of the Pentax Q mount is rather large (9.2 mm) for a mirrorless camera with such a tiny sensor, this wide-angle lens is retrofocus, which is more typical of an SLR.  The simple optical design and diffraction due to the slow aperture result in poor image quality. The Q 04's image quality is worse than that of the Q 03 Fish-Eye lens.

This lens is called the "Toy Lens" because its image quality resembles that of cheap plastic "toy" film cameras.

Kiev-6S: Budget medium format film camera

When I decided to start shooting film again, I planned to use both 135 (35mm) and 120 (~6cm) format films. So I bought a development tank that supports both formats.

Of course, shooting with 135-format film is easier. There are many cameras available for it. However, I recently acquired the Carl Zeiss Jena Biometar MC 80/2.8 lens and wanted to test it with 120 film.

Consequently, I bought a Kiev-6S (Киев-6C/Kyiv-6S) film camera manufactured in 1983. It is a budget medium format (6x6) SLR with a Pentacon Six (P6) mount, which is called the Bayonet-B (Байонет-Б/Mount-B) in this case.




Compared to the Pentax Super A, the Kiev-6S is bulky, large, and heavy.

The camera came with a complete factory kit, including two viewfinders and a Vega-12B 90/2.8 lens. The 6x6 frame size is 56x56 mm, so the diagonal is approximately 79 mm. A 90/2.8 lens for 6x6 is equivalent to a 49/1.5 lens for FF.

I use the Kiev-6S with the waist-level viewfinder and the Carl Zeiss Jena Biometar MC 80/2.8 lens.




The camera is in good condition and has seen little use. I shot one roll of film, and the images turned out well, with consistent interframe spacing (important for Kiev-6S/60 models). The main problem is achieving accurate focus. It is harder than I expected.

One notable feature of the Kiev-6S is its shutter release button, which is designed for left-handed use. I have no problems with it.

Mitakon [Zhongyi] Creator 35/2: Adapting for Pentax film cameras

The Mitakon [Zhongyi] Creator 35/2 with Pentax mount can damage a film camera. This is due to the absence of a groove for the stop-down indicator. Therefore, I modified the lens for use with a film camera.

I removed the mount and cut it with a drill and file (I used the M42-Pentax K adapter as a template).





This groove moves the stop-down indicator when the lens is mounted.




The modified lens worked well when tested with the Pentax Super A, despite my sloppy work.




One rhetorical question: Why couldn't Zhongyi, the manufacturer, do such a simple thing itself?

Pentax A 35-70/4: Samples [2] - FF - 70mm - f/4

Camera: Sony a7c (FF, 24MP)
Lens: Pentax A 35-70/4 at 70mm and f/4

There is slight pincushion distortion at 70mm. This focal length provides the greatest magnification.

Sony a7c: Firmware updated to v2.01

I updated the firmware on my Sony a7c to version 2.01.



Several weeks later, it still works well. I haven't noticed any changes. The FTP transfer, which I use often, is still working properly without any reconfiguration.

Lenses for the Praktiflex and Praktica (PDF)

Here is a PDF of Christian Großmann's "Objektive der Praktiflex und Praktica":


The PDF contains descriptions of M40x1 and M42x1 lenses. It also contains useful production year data. According to the data, for example, my Carl Zeiss Tessar 30/3.5 was made in 1947, which is what I expected.

My digital cameras (2025-05)

This is a list of all the digital cameras I have owned or currently own.

Fixed lens cameras:



Interchangeable lens cameras:



My interest in old digital cameras has waned. Of the modern cameras, I considered the Ricoh GR III and the Sony ZV-1. However, I doubt that I will buy either one.

I am interested in the Fujifilm GFX100S, but even a used one is too expensive.
