Zeiss’ s biota 58 mm, which is a copy of the very famous monofocal Russian old lens Helios. To be exact, the ancestor model of Biota is the source of Helios, and this time the biota seems to be descendants of the head family, I can not translate it as a resident of the lens lens none at all.

Lens and manufacturer introduction

Carl Zeiss Jena BIOTAR 58 mm F2.0

The character of Biotar which is often seen in Helios’ subtitle which is overflowing on the market.
As I become more familiar with the old lens, someday I would like to have a different lens than Helios’s looks like, … It is not as cheap as Helios ,,,! Finally got a hand!

I am taking a picture with Canon 5D mark III again this time.

Today’s New Year’s New

· What is the difference like Helios?
· Consider how to take this lens that fits the Biotar 58 mm

Bokeh taste, depiction of frame periphery

It will be a blur that you have to try whatever you put on first.
Moreover, it does not start not to see the guruguru blur. This lens is.

I’m turning around!

Ridiculously!

Flowers are easy to turn!

Although it was making a fuss, in fact the eyes came to the focus of the focus side.
Rather than saying sharp, I feel that it was a while since I felt so relieved with the release of F2.0 with images with tangy and crispy.

For a moment I thought that it looks like a modern lens, but as light comes in, I feel the taste of the old lens in the whiteness that comes into the halation feeling of the highlight saturation feeling and halation.

Oh?

Oh? Oh?

Somewhat far nostalgic.

It is different!
This is infinity is not in agreement! ! !

Ah! Returning or something is awkward.
Examining it, “Returns: 14 days, buyer pays return shipping.14 days return goods.
On the day I am writing this article, it is just 14th day. It is 14 days after I put the arrival date, but I am absent. Will you come back three days before that?

Well …
I guess there is no problem unless you take a landscape …. Rather, the focus is on the front, the viewpoint of shooting is a little funny in the back.

Actual flight ,,,,

I left it as it should be checked later.
It was perfect if you were walking down the street. . .

Postscript: 170718
I told you in the comment that 5Dmark III certainly does not fit the lens properly, I feel that part has not reached infinity. When it was α 7, it went out infinitely without any problems.

& nbsp;

It is a consideration of blur by trying again.

Front blur, back blur, I wonder if it got it well.
Is it a two-line blur like a blur like a sentence of a post-blur telegraph, a red cone, etc. Is it the corner of the image’s most peripheral in release 2.0, is it like this?

It feels interesting that the feeling of floating up when blurring comes in with a sense of distance not far far away is distinctive.
Although it is not limited to Biotar, it is a blurred shake a little tighter than Helios. However, I feel that it is not a hard blur.

The yellow color of the central part of the flower was easy to saturate, it was hard to grasp the pin alignment.

I feel like this can be done by Helios as well.
I feel the expression of the dark is similar.

Line depiction, color taste

I am walking while releasing and taking F8.0 and so on, so shots similar to the above blur term are lined up.

Compared with Helios, is the color paste natural?

If Helios is not bad, and Biota says “a little softly” the image at the time of shooting, Helios said “it’s pretty light”.

I feel like this, does the whiteness similar to Helios?
Corn seems to be split and sharp.

It is a taste like a hard thin core like a concrete or a grill.

It seemed like an Industar 50 somewhat. I am sad that the price difference is much the same. Pain cake with saturated feeling of crisp and highlight Industar 50.
It is probably a catch phrase that can not be sold.

Although I compare it with Helios, I think that it is a nice lens that gently wraps from the image periphery and the highlight part while describing it with sharpness when viewed alone.

Whether the focal plane is sharp and split in any situation.

Purchase route, repair and versatility, reference at purchase

Carl Zeiss Jena BIOTAR 58 mm F2.0

It is 60 cm in the shortest shooting distance, is there a relatively large number on the M42 mount?
In the manufacturing around 1957, because there is no “T” mark, it seems to be the latter Biotar.

If infinity is eventually 5D mark3, depending on the type of Biotar it seems that it will not go to infinity depending on the screw part of the mount does not turn to the end.

This time Biotar 58 mm

This type of Biotar seems to need attention because it may be hit by the mount even with single lens reflex or mirrorless single lens.

No problem Biotar

Since there is no protrusion near the lens behind, infinity will come out without problems with a single lens reflex camera such as Cannon EFmount.

In this respect Biotar may not be for beginners for a moment.

color, flare, ghost

With such a frame, in Helios it will take more halation and white turn around.
Lightly it seems Halle. The line may be an easy-to-photographed halation that will remain neat but graceful.

If you want something like filter processing, it might be Helios, but if it tastes lightly film photographic, it might be Biota.

Looking back and analyzing the pictures that I thought was able to be successful

I thought that I had never taken such a thing, I posted it as a successful photograph.

I think that it may be possible to narrow it a little more, but it is my first time feeling cut off like this as a composition is a little nice.

Comparison of aperture and shutter speed

Aperture F2.0, shutter speed 1/1000, ISO 500

Difference between depictions came out considerably clearly.
Liberation is easier to stick, but I feel that the taste of Sharp of Biota’s narrowed line is also good.

Aperture F8.0, shutter speed 1/100, ISO 1250

Directing direction of shooting, as a portrait lens

It seems to be good for portrait, it looks like it’s finished with a dignified item.
Other than that, it may be hard to carry around unless you fix the infinity. . .

Around where I walked

In the vicinity of Yoyogi Uehara on a sunny day,

Late afternoon, we flapped Shimokitazawa where flutter and light rain flickers.

It is a newly changing Shimokitazawa, but there are still enough fun tastes to take pictures.

I am still short of walking.

Shooting camera information

Canon 5D mark III

The camera is 5 D mark III, the image quality is raw uncompressed shooting, the picture style at shooting is the standard and it is used only for 5D monitor check.
Jpg will be thrown away when importing to PC.

Since development is currently in Photoshop CC 2017 and we want to leave the characteristics of the lens in the photograph, we only adjust the extent to make the brightness uniform by the exposure dose.

Mount

[us_mountSelect something="M42_EF"]

Aperture

Recently, I released a scene that I care about Compared at around F2.0 and Faround 8.0. So it is a feeling to stop one by one. I have not done recently what I want to shoot.

Shutter speed

The day of sunny Yoyogi Uehara, there were quite a lot more than 1/1000.
Shimokitazawa of light rain was around 1 / 100-1 / 1000.

ISO

As usual, with the old lens, the exposure measurement of the camera is quite blurred according to the lens and diaphragm and only roughly matches, so it feels like it will fit while shooting.
When it is released, it is much higher than the exposure measurement of the camera, but when you narrow it, it often matches the camera’s exposure measurement as it is measured, but the viewfinder gets a bit darker and it looks a little hard to see.

White balance

It was always auto.
Even in comparison photographs, it is also necessary to worry about exposure considerably from white balance.
