The Uvex i-3 safety glasses (spectacles) are good, but they do get scratched up a lot. So I replaced them with Uvex Pheos One (9192370).
Simpler but cheaper.

Molykote 33 Light: application for lenses
I purchased Molykote 33 Light grease primarily for lens applications.
The 33 Light reminds me of GM Special Lubricant High Temperature grease, they have a similar consistency (NLGI 1). However, there are important differences:
1. GM provides better lubrication. Apparently because of the PTFE.
2. Molykote does not separate or bleed, unlike GM.
3. Molykote is almost odorless.
This is why I switched to using Molykote 33 Light. The first application was on the Pentacon 30/3.5 lens. It had never been disassembled, the original grease had dried up, so the focusing ring was too stiff.
The focusing mechanism of this lens is like the "inverted" mechanism of the Индустар-61Л/З (Industar-61L/Z) on which I tested the greases.
First impressions after using Molykote 33 Light are good. But I wish there was a PTFE additive for even lighter movement.

SZ Viewer: "lacks permission android.permission.BLUETOOTH"
The updated version of SZ Viewer may display an error message:
UID ... / PID ... lacks permission android.permission.BLUETOOTH This is a problem with some Chinese Android 12+ devices: mainly Xiaomi, but other brands are also affected (Oppo, etc.). It is caused by an incorrect implementation of the Bluetooth stack (permissions).
There is a workaround, but I don't plan to try it right now. SZ Viewer users can either manually roll back to an older version, or hope that the manufacturers will fix the Bluetooth bug of their devices.

My Mosler Photoguard 35/2.8 and infinity focus
My Mosler Photoguard (Tokina OEM) 35/2.8 focuses beyond infinity, which is inconvenient. I've tried different T[2]-mount adapters, but there's no difference. At the same time, I don't want to disassemble the lens to adjust it now.
So I chose the simplest way. I put some pieces of thin foil between the T[2]-mount adapter and the lens and corrected (returned back) the orientation of the lens with the screws of the adapter.
It looks not very good, but focusing became almost at infinity.
But in the future, of course, it would be nice to adjust the lens.

34960-81A00 vs 34960-81A20: VSS for my Jimny
One Jimny owner offered to swap my 34960-81A00 vehicle speed sensor (VSS) for his 34960-81A20. Since I have several 34960-81A00 sensors, I of course agreed.
On the left is the 34960-81A00 (for 4.09 + 205/70R15 or 4.3 + 175/80R16), on the right is the 34960-81A20 (for 5.375 + 175/80R16).
Using the diagnostic software (speed value for ECM) and GPS, I made a comparison.
Stock: final drive ratio 4.09 + 205/70R15 (about 26") tires, now: 5.375 + 30".
With the 34960-81A00 (stock) VSS:
("Скорость" means "Speed" in km/h, I forgot to change the language)
VSS shows 60 km/h at 51 km/h. Quite an overestimate.
With the 34960-81A20 VSS:
("Скорость" means "Speed" in km/h, I forgot to change the language)
VSS shows 48 km/h at 50 km/h.
This way the readings are closer to the real speed. The only bad thing is that the indicated speed is lower than the real one. But this is on the diagnostic, whereas the speedometer readings are the same as the real speed.
Of course, with bigger wheels (32"/34") the indicated speed will be lower, but now I use only 30" for long distances.
So I left the 34960-81A20 installed on my Jimny. And I need to correct the speed coefficient for the RIF-500 trip computer.
By the way, the automatic transmission control module of my Jimny doesn't use VSS at all. Instead, it receives a fake signal from an NE555 pulse generator to enable 4th gear and lock up the torque converter even when the low range of the transfer case is engaged.

Rockbros [compact] bicycle bell
A compact bicycle bell from Rockbros.
They call it "hidden design". The bell looks like a ring that wraps around the handlebar. So you can literally ring the ring.
The hex key for the mounting bolt is included.
It looks really compact on the bike.
The "hammer" is quite far away from the bell, so it won't ring accidentally when driving on a bad road.

M42x1 - Sony FE/E adapter (5 mm)
This is a thin adapter for M42x1 lenses and Sony FE/E mount cameras.
Often such adapters are very thin: 1-1.5mm, but this one is the rare 5mm version:
It's not just an adapter for M42x1 (like this one). It is an adapter with a short flange focal distance. In this case it's 18mm (Sony FE/E) + 5mm (the adapter) = 23mm instead of the standard 45.5mm for M42x1 lenses. This means that a standard M42x1 lens focuses beyond infinity.
Such thin adapters are used for various experiments and homemade things (adapted lenses, macro equipment, etc.). I use it for a rather rare old lens (with a simple adaptation).

Samsung NX2000: cheap 20MP camera, welcome
I left the Samsung NX series, but the Samsung NX series didn't leave me. I already have the Samsung NX300, which unfortunately turned out to have a defective AMOLED screen. It is extremely difficult to use outdoors. I also have a good Samsung NX10, but I don't really like its 14.6MP sensor.
So I was looking for something cheap with a 20MP sensor for my two NX lenses (20/2.8 and 30/2). Based on price alone, I bought the [used, of course] Samsung NX2000 (body only):
(with my NX 20/2.8 lens)
It's a strange camera (introduced in 2013) compared to other NXs (except for the even weirder Galaxy NX EK-GN120 with Android).
The NX2000 has only five physical buttons: shutter, video, home, play, "direct link", and only one dial (but it can be pressed). The rest of the control is done via the touchscreen, which is quite large (3.7" 800x480). The screen is also a regular TFT-LCD, and not an [AM]OLED (after the NX300, I think this is an advantage). But it is fixed (not articulated).
Other features: 20MP 1.5x crop factor sensor, mechanical shutter only (up to 1/4000, x-sync 1/180), microSD card, not bad BP1130 battery (same as NX1000/NX200/NX300/NX500), charging via microUSB (сan be in use simultaneously).
The NX2000 concept wasn't a success, so the NX3000 (introduced in 2014) became more conventional (it doesn't even have a touchscreen). This makes it all the more interesting to see how good the NX2000 is. Especially since I'm not a fan of the NX300, which isn't very usable compared to the NX500.
This copy of the NX2000 is certainly not in perfect condition: some wear and tear on the body, scratched screen, about 19k shutter releases, dust on the sensor. It resets the time when the battery is removed, and the shutter button is not quite clear to press. But the important thing is that the screen works fine. I can easily take pictures outdoors.
By the way, this is my sixth NX camera (after NX10, NX20, NX300, NX300M, NX500).
Why haven't I replaced the screen on my NX300? It's hard to find and too expensive. And I don't trust AMOLED anymore.
