Macro shot ?

Z55 – A7R4

Once before I found a trouble of manual focusing in the Sony camera. So, I was testing Zeiss 55mm lens on A7R4 body with Focus peaking and the Focus magnifire. —— This time both function worked well = AND I amazed by its fine details of the captured image. = The silk flower was 100 cm away yet the enlarged image showed a real close-up = macro quality.

Z55 – A7R4

I wonder IF this fine quality came from the quality of the Zeiss Sonner FE 1.8/55 ZA lens or the camera’s 60MP image sensor ?

AI Nikkor 50 – A7R4

For comparison, this one was AI Nikkor 50 mm F1.2 (at F1.2 / 100 cm) on A7R4 (this 50 years old 50 mm lens seems to be a bit softer than Zeiss 55 mm —– But, F1.8 lens got to be sharper than F1.2 !)

AI N 50 – N Z7

Then, how about the AI Nikkor 50 mm F1.2 lens on Nikon Z7 ? It’s haed to tell if a bit softer image was caused by a larger F aperture (F1.2 instead of F1.8) or a bit fewer pixel number (46MP instead of 62MP).

P110-24 – A7R4

On the same setting, I tested it with the remotest possible lens = Pentax 110 Auto 24mm F2.8 lens === 24 mm lens image was far smaller than the 55 mm lens. Still, the enlarged image showed quite a fine detail !

It’s suggests that as long as the lens was seriously designed good lens, its can produces very fine details = IF the resulting image was not very fine, it was because, the camera / image sensor / image processer was not good enough.

P110 – NZ7

This is the comparison = The same Pentax 110 lens was mounted on the Nikon Z7 body through a homemade NEX – NZ adapter. —– Even though the same optical image was projected, the smaller sensor seemed to produces a bit rougher image.

Godo – A7R4

So, see the image of the lens which was not seriousely designed or made = homemade Godo-lens.

NZ-B – N-Z7

Then, how about the image made by yet another fine camera Nikon Z7. —– But (you believe it or not) I don’t have an authentic lens for this Z7. (I’ve been empoverished by its XQD memory (made by Sony), expensive spare battery etc —– I can not afford to buy their lens.)

So, the Z7 camera was tested with another homemade lens, NZ-B lens which showed very fine undefined image !

Daikon 2020

So, I’m watching the same windowscape of my kitchen window.

Only a difference in these days was, the leaves of the Daikon head. Which was growing well. Some of you might say that I can cut them small and eat or put in a Miso soup —– I know. But I want them to live free and grow. (I’ve tormented the Daikon root badly enough, boil her alive and eat = I need to make a hypocritical excuse by humainly saving the leaves)

It’s a spring. (Forget the hell outside or the world beyond)

So, the Daikon is having her flower bud —– though, would the flower open or not is the different story.

When she got 30cm tall, before opening the flowers, she lost a vigor of the life. I couldn’t see any reason why, —– it was same as last time. How shame. (May be I need to learn about the Daikon plant start from its seed, not the left over top of a Daikon food.)

MP Cherry 2020

Those photos of the Multi-petal Cherry was taken by a homemade lens, NZ-B lens on Nikon Z7


May be in a normal sense, such lens may not serve for a photographical use. Yet still, any image could be an image as long as the author = I wanted. Why not ?

Under the COVID-19 pandemic, our activities and the movement has been restricted, so the picture I am producing may looks one pattern too. (Sorry)

The lens NZ-B seemed to have two glasses of which I re-mounted into a zooming barrel and able to focus from infinity to 1/3 close-up. Still, born to be a simple junk lens the image never be sharp. —— But that was what I wanted. 😀

A kind of Tree

It seems most of those trees are Oregon Maple in their winter guise.

The lens used was homemade NZ-B lens on the Nikon Z7

Now the street was deserted —– may be because of the spread of the COVID-19, which was said to be 8.000 cases, 400 death in this country, — what can I say.

Spring Equinox 2020

The photos here were taken by NZ-B lens on Nikon Z-7
But this one was by Pentax 110 24mm lens on Sony A7R-IV

Whether the day was something special or not, when it was dull, photo would be dull. Especially when it was taken by the dullest NZ-B lens. (Still, I think, even if the lens was genuine Nikkor or Pentax 110 lens, the sky like this will be looks like dull —– What else ? )

By NZ-B lens

Whether western people feels it is not so special, Japanese cerebrate both equinox as a national holiday. (春分の日、秋分の日=since those days were related to the rice growing agricultural calender they are important in the Japanese tradition)

The same sky in the evening, taken by NZ-B lens on Nikon Z7 —– I like this soft tone.
And the same sky, further down in the evening by Pentax 110 24mm on A7R-IV

The sky looks quiet.
