My kvas/souer beer pops like a real beer!

A Spotify rant. Show more

This gives an idea how it looked.

Yesterday's moon. 300 and 500mm.

На днях приготовил квас, правда закваска на простых дрожжах.

Сейчас эксперементирую с получившейся закваской: сейчас она пузырится в кострюле с кофе.

Паралельно, делаю закваску на ржаной муки. Думаю, ее пустить на квас и хлеб.

Кроме кофе, попробую заквасить клубнику, а если получится и понравится, то и свеклу.

My first attempt of taking a picture of the night sky and some telephoto experiments.

First experiments with a 500mm lens.

"Understanding exposure" by Brian Peterson is a great book to get familiar with the manual mode.

Other books on photography that I've jecked out in the library are much less informative.

A friend of mine figured out that my 135mm $14.00 lens is the fastest one.

A lens speed is actually quantifying its aperture, or the amount of light it gets trough.

This one is f/2.8.

With a wide open aperture, the shutter speed is the fastest (thus the name).

However, the dept of field is the shallowest. This means that the focus area is limited. It's is usually desired for portraits.

It is also required for action shots, to get them sharp...

At 300mm a slight move on a tripod has dramatic consequences. On my current cheap tripod it's very difficult to point to objects.

This is the main reason I want to invest into a better one.

Right now my "main lens set" is:

* Canon 15-45mm
* Vivitar 28-210mm
* Minolta 100-300mm

After some experiments, I realized that I like telephoto lenses, so my second order was more targeted.

28-210mm and 100-300mm cover most of my needs. I really was hunting for a >200mm lens. And got other to get free delivery! 28-210mm felt very lucrative.

This is my first order. It let me to experiment with telephoto lenses (135mm and 200mm) and a wider 28-85mm zoom lens.

It was really a moment when I realized that I need a tripod. The beauty of a tripod is that you can take you time and set up everything in your own tempo.

Here are the lenses I've got.

I got the Canon lens with the camera. It's great for taking wide shots, has autofocus, but feels like driving a car with an automatic transmission :)

Other lenses is the result of my random search of keh.com.

Notice attached he bottom of the adapter, a mount for a tripod. As old lenses are heavy, extremely heavy in comparison to modern lenses, a tripod is a must. Having the while thing mounted on the adapter, makes the mounting point closer to the mass center and puts less pressure in the camera mount. I don't know if it matters, though.

I decided to try Minolta lenses with MD or MC mount.

Because of a very short flange distance (the distance between the lens mount foenge and the sensor) it is possible to adapt almost any lens without loss in quality. An adapter just needs to compensate the flange distance of the lens mount. There is no loss in quality because the adapter is just a ring, there is no any glass in it.

As you can see at the picture the adapter is placed between the camera body and the lens.

A bit about my hobby: photography with manual lenses. I was looking for a mirroless DSLR. One of the reasons I wanted it to be small and compact, as I was concerned that a bulky camera would be too much effort to carry around.

I was looking into Sony a6000 (good price) or Sony a7 (full frame).

In the end, I got Canon EOS-M in perfect condition with a 15-45mm lens. A professional photographer was selling his "backup" camera and made a very good offer.

My first attempt at looking into the night sky. MD 100-300mm Minolta lens at 300mm.

Lakes are great to experiment with lenses.

Taking pictures with a fully manual lens is a challenge, but i'm getting better at it.
