Helios 44-2 58mm f/2 lens sample photos without pp.

quoted from Helios-44 | Camerapedia | FANDOM powered by Wikia
Helios-44 is a series of standard lenses for SLR cameras, produced in Soviet Union.... Based on the lens Biotar 2 / 58,....

So every version has slight different things like shorter(or longer) minimum focus distance, different aperture blades, etc.

This technical details were only for the Helios 44-2 version.

Helios 44-2 58mm f/2 lens technical details:

type: Prime lens
mount type: M42
optical design: 6 elements in 4 groups
aperture range: f/2 ~ f/16
aperture blade: 8
minimum focus: 50 cm
filter thread size: 49mm
weight: 230g
length: 57mm

I don't much care about this technical details of lens. But sometimes it can be useful.
For example, if I already have same uv filter or hood like this lens, I can use with this lens.
And I'm walking long hours when I do photo-walks. So if lens wasn't heavy, it was very suitable for me. That is the reason that I mostly shoot with prime lens.
So I do check those things from the technical details.

You can read more about the lens from here:

Technical notes:

These photos were all taken with handheld and I used M42 lens to Sony E mount or Micro four thirds adapter so I have no idea about aperture number for the photo.

When I am taking photos, I do use Raw file format. So I need to convert raw file to jpg file and during that time, I do some post-processing--this is kind of darkroom process in developing film.
And when I do this, I don't use any default setting from Rawtherapee--open source software because there has some image modification settings like sharpening, micro-contrast and among other things.
I don't use Adobe Photoshop but this also has same kind of default setting with sharpening.
This isn't important for photography. But this is about the lens--what kind of photo I can take with this lens. So sharpening won't help to know about the lens.

So when I do use Rawtherapee, I removed all the default setting.
I will do these adajustments, if necessary:
 - click the auto button in exposure tab--automatically calculate the exposure value,
 - adjust exposure value, if overall image was still dark or too bright,
 - adjust contrast(between 3 and 18) in L*a*b* adjustments tab,
 - if there have some areas were too dark or too bright which makes me feel unbalance the overall look, adjust the shadow/highlight value.
 - Sometimes, white balance set to auto or slightly reduce the temperature value. Because Sony A7's white balance value was quite terrible when I do use other brand lens--not Sony E mount lens.

Olympus E-P3 camera with Helios 44-2 58mm f/2 lens:

I didn't use Rawtherapee because I like the color of Olympus Viewer 3 produced.
I did only adjust exposure value. And then adjust level in Gimp--open source software.

I think it is morning glory or ipomoea kind of flower.
