David-type hexagonal bokeh Industar 61 L/Z. Not only that, but this lens, which has a reputation for being sharper than other Russian lenses, is just right.

About lens

M42 LZOS Industar-61 L/Z (MC) 50mm F2.8

Most of the famous Russian lenses are copy lenses based on Zeiss’s famous lenses, but this lens seems to have a completely different origin, and its influence or the making inside is completely different from other Russian lenses. ..

In other Russian lenses, small screws are often responsible for fixing parts, but this Industar 61 is a combination of screwed parts to fix, transmit force, and determine the range of movement, so it is in the middle term. It looks like a German lens.

Today’s Agenda

– Consider the lens centered on the rumored star-shaped bokeh and sharpness
– Check if it is possible to create a depiction that makes the most of the old texture.
– Continue walking around the central line

Bokeh, depiction around the frame, color

It’s a soft bokeh, but it doesn’t seem to saturate like a typical Russian lens.

I will write in detail in the sharp section, but the sharpness and balance of the focus surface is very smart, and it can be said that it is as descriptive as a modern lens.

Since the color does not fade, I think it would be good to add contrast and take advantage of the blurring with the depth.

David Six-Stars Bokeh Special!!

After all it cannot be helped not to feature in star bokeh.
In addition to Koenji, I tried various things including other sunny days.

When I walked in Koenji, unfortunately the weather was such that light rain occasionally fluttered, and I aimed mainly at the star blur with the light source of the store.

Similar to Helios’ round bokeh, a small light source such as light is put in the back, and the focus is basically at a position quite close, and it is an image that star blur does not work well unless it is much closer than Helios.

The white part of these flowers can be made into a star, but it may be possible if the weather is good.

It’s easy to make the aperture blur from F5.6 to F8.0 to get only the star blur, but it’s unexpectedly difficult to compose the subject with a close-up shot in front of you.

The reason is that in general close-up photography, only the subject in the foreground needs to stand out, so it is generally true if there is depth.
However, when it comes to star blur in Industar 61, the restrictions on the aperture value are directly linked to the shape and size of the star, so it was quite difficult to compose based on both positions.

With this distance to the light source in the back, it is easy to compose the focus surface in the foreground.
　

I tried various things to see how far the light in the city could be used.
The vending machine seems to have a little insufficient light. Furthermore, because it is an LED, it blinks at high speed, and it is difficult to catch the moment when it is shining.

The light is the illumination of the signboard of the ramen shop. It is quite so if it is shining strongly on the signboard.

Car hazard lights are not enough. It seems to be okay at night.
　

At the bottom right, the light on the signboard is pretty clear.
It seems that such flickering lights are easy to make star bokeh.

Taken at a later date on another Industar 61 on a sunny day

After all, like the round bokeh of Helios, I wonder if the star bokeh is easy to come out in the sunlight through the trees on a sunny day.
However, this composition is difficult to make in actual portraits…

A photo of Helios’ bokeh

Helios shooting under similar conditions looks like this.

Resolution, sharpness, aberration

It’s surprisingly sharp and sharp.
I can’t think of it from the image of Russian lenses I had so far.

However, it seems that the sharpness does not come up unless the light source such as sunlight is exposed to some extent, and it seems that it is always as sharp as the current lens.

The light that hit the shoes was sharp, and I was able to take a good balance with the darkness in the back.
Even if it’s cloudy, it seems that it will be possible if the sun goes in.

Full opened aperture F2.8

It is a comparison with the following photo and aperture.
It’s sharp to some extent even at full aperture, but the depiction of F8.0 is also nice.

Apature F8.0

If you don’t think about star-blurred lenses, Russian lenses, old lenses, etc., you can shoot like this lens.

If the weather is nice, the leaves will be sharper.
This lens, including the star bokeh, may have to be taken out on a sunny day.

It’s a shot near nightfall, which isn’t bad, but I feel like I want more old-fashioned saturation, so Helios and Jupiter may be more suitable.

It will be sunny at a later date, and sometimes it will be shaded by clouds.
When the reflection of light comes up, it feels good to stand out in the shade of a tree, the focus surface, and the blur.

I tried to narrow down the blue sky to F16.
I don’t feel any distortion around the image, and I don’t mind chromatic aberration.

for Parchase

Is the price range of eBay、
price range of eBay about $100 to $150 including shipping? If it’s Yahoo Auction Japan, it’s up to about 20,000 yen.

To be honest, I don’t think that cheap ones have been repaired.
I’ve only repaired 3 of them yet, but it was a big deal inside, so I think it’s better to avoid heavy focus helicoids.
Compared to other Russian lenses, there are many places to apply grease, and there are a lot of greases everywhere, and the accumulation causes weight such as helicoids and oil odor.

Currently, I have 5 or 6 of them, but all of them have heavy focus helicoids and seem to be difficult to clean.

for Portrait

I would like to try a portrait with star bokeh.
I have mentioned it many times in the text, but I definitely want to try it on a sunny day.

Where I walked

“Koenji” town shooting recommendation ★★★☆☆=3

I thought it was about the same size as Kichijoji, but it was a place with a slightly different sense of scale. People from the countryside of Chiba are not familiar with the other side of the Yamanote line.

It was a street where I was at a loss as to how to walk, as if there were many similar narrow shopping streets.

I wanted to go a little further away if it didn’t rain, but it wasn’t a good day to walk around the city.

There were a lot of ramen shops, and I was thinking of trying one, but I was fascinated by the Nagoya throat bowl and decided to try it.
It’s a bowl of motsuni. Especially, the taste was as expected and it was a normal price.

There was a small bar and a shopping street with side dish shops on the left side of the south side of the station.

This area may be the most important point for taking pictures of the city.

There are many shops that seem to be affordable, and when I come next time, I would like to eat around here.

There may have been various things if I walked along the roads around here, but the rain was getting stronger and I was a little tired, so I went home.

About Camera

SONY α7

Raw development

Development is Adobe Bridge CC 2017, so I want to keep the characteristics of the lens in the photograph, so I do not change the contrast or saturation at all, no adjustment, no filter.
Occasionally, the brightness is adjusted according to the amount of exposure.

Camera settings

The aperture is based on F5.6 to F8.0, which causes star blur, and F2.8, which is open depending on the situation, is also used.
The shutter speed is about 1/400 when the shutter speed is reduced to 1/1000, and ISO is used with the feeling of adjusting the brightness according to the frame.
White balance has been “sunny” all these days.

and More

It seems that the David type is also called a hexagram, but according to Wikipedia, the David type seems to have a line inside, so it may be a hexagram blur to be exact.

Actually, I’ve known this lens for a long time, but I couldn’t get close to it because it felt like a play lens with only star bokeh.
However, when I took this picture, I thought that the sharper sharpness and the part that can be approached even with a standard angle of view of 50 mm would be a good lens to be respected more.
I feel that the goodness of this lens is not well known because it is featured only in star bokeh.

Afterword-How to get the star bokeh-

As for how to make the star bokeh, it is almost the same as Helios’ round and round bokeh, so please refer to this.
