That's one reason i'd create this thread. To find ways to support him in his work.
It could be some forum members from poland own a current Pentax camera.

What brings your post anyway?

The red AF assist light is not really annoying.

The topic about AF assist lights on pentax K-1 has it's own thread:
AF Assist light is not available with the AF540FGZ or AF360FGZ - PentaxForums.com

Tripods & Body Straps

I choose every single component in advance so they'll fit together.
Example:
Tipp: Blackrapid und Sunsniper Kamera Gurt und Stativ - kein lästiges Schrauben mehr! - gwegner.de

I once had a tripod for 20€, but this was just strong enough for a 250g compact camera in vertical position.
Got a 150€ Manfrotto 8 years later.

Currently i'm using a SunSniper together with plate on every lens and camera.
All plates have the same Manfrotto quickmount system (besides lenses over 2kg and heads for these lenses, they use arca swiss).

It seems this discussion get started every year - although phyiscs are the same since the invention/discovery of photography.

Some examples:
Lens Aperture and Sensor Size - PentaxForums.com
On aperture equivalence: are FF lenses on crop bodies a bad idea? - PentaxForums.com
f-stop crop - PentaxForums.com
dumb f-stop question - all f-stops created equal? - PentaxForums.com
caclulating f-stop relationships - PentaxForums.com
DOF and F-stop question. - PentaxForums.com

More clarification:
T-stop vs. F-stop In a Camera Lens - Articles and Tips | PentaxForums.com
Understanding Crop Factor | B&H Explora
Depth of Field, Part III: The Myths | B&H Explora
What is equivalence and why should I care?: Digital Photography Review
This Crop Factor Calculator Makes Sensor Math a Breeze
Aperture - Wikipedia
A Tedious Explanation of the f/stop

Bringing in the correct names:
aperture (written, can be f/t-stop, open, close or relative to the minimum/maximum of an lens)
t-stop (for transmission stops, by convention written with capital letter T) is an f-number adjusted to account for light transmission efficiency (transmittance)
f-stop (mathematical result of dividing focal length with lens diameter)
equivalent f-stop (regarding depth of field, to get the same sharpness on another sensor)
lens speed (independent from sensor, like f/t-sop)

Conclusion:

Many information has been written by me about quality (longevity/durability) of flash memory:
Quality of memory cards
Certain SD Cards Clear Buffer Faster?
Good SD card
SD Card recommendationsI wouldn't recommend SanDisk (Ultra) at all. Using mostly the cheapest, least realiable TLC NAND now, SanDisk isn't was it was several time ago.

SD Cards We Recommend for Dash Cameras
SLC vs. MLC: Accessories Talk Forum: Digital Photography Review

Nowadays SLC unfortunately is only beeing used in industrial cards (high endurance, low performance).
So today (e)MLC ist the best choice. Like Panasonic Gold Pro or Lexar Professional. Maybe Samsung Pro(+) too.
