Empty Town

These photos were taken by the Pentax 110 Auto 24mm lens mounted on the Sony A7R-4 camera, while I took a shopping tour to the centre of London through rock downed empty street. (When I need to get a soy source, I have to go Japanese food shop in the centre.)

As you might have guessed, the advantage of this lens is its small size = almost like a body cap. Together with small mirrorless camera, they easily slip into my pocket. Why do I need to use heavy big lens instead ?

Cropped Image

These are the photos taken by the Pentax 110 Auto 24mm lens on the Sony A7R-4 body, on my shoping tour to the centre through rockdown London street. Though, the images were heavily cropped —– as if the image was discovered in a corner of the original photo.

Despite its humble origin (came as a £5 junk) the pentax 110, 24mm lens I got, gives quite sharp image, hence, able to give quite usable image even after a heavy crop. So, some of the picture may looks like a telephoto image. ( 25mm lens image cropped to 1/2wide and 1/2hight would be an equibarent of 50mm lens image, or 1/4 x 1/4 would be a 100mm telephoto image.)

And the question IS, how many people in the world need to have the hi-lesi photos ? —– My photos in this blog are about 1200 x 800 (500K), even though the original image from the A7R-4 was 60M (9504 x 6336) —– in the other words, 9500 : 1200 (1/8) , 6336 : 800 (about 1/8), the image cropped down to 1/8 x 1/8 shouldn’t have any trouble on the apparent quality of the image. As we are living with the image originated from the dream or bague memory as well, images may not needed to be pin-sharp or forensicly detailed.

Sony Extension Ring

To prevent the close contact, the postman left a percel from China outside of my door while shouting Your Post = I got an Extension Ring delivered today.

To have an even closer shot, the Extension Ring is a pretty handy device. You may find such ring for Sony (10 mm and 16 mm set) as cheap as £15 on eBay. And depend on the lens used, you may get quite a close-up photo (the shorter the focal length the closer you get —– though, depend on the lens, the closed image might be pretty bad unless you stopped down the F-aperture a lot.

With such a cheap price, I bought 3 or 4 set of Sony Extension Ring. Since, I discovered, not all of them are good. Some loose bayonet make the joint wobbly (only 0.1 mm wider gap of bayonet makes it loose) —– even worse, some of them stack solid (only 0.1 mm longer bayonet claw can block them disengage) = To separate the camera body — Ring — Lens, I needed to hack-saw the ring and with sheer force, I ripped off the Lens ! (Photo above right two = used be the DG-NEX Extension 16 mm ring = the left over after a hack-saw job.) The trouble is, you discover the trouble only when you HAVE engaged the Lens – Ring – Body. = Then you realised that you got the trouble of stacked bayonet. —– Because of the internal mechanism of the bayonet, we can’t see which part was blocking the ring to rotate back.

This IS what made in China meant. On the eBay, you may see many “Sony Extension Ring” with different prices —– Give close looks = The ring came from only few original manufacturer, then, different vender selling it in a different price. = Expensive doesn’t mean good quality. Manufacturer seemed to sold off bad lot for give-away price then, corrupt vender sold them in the net, expecting most of the customer never bothered to complain for £15. —– So, on the end I bought plastic one = Easier to hack-saw and when I needed, easy to brake-off before the lens or the camera body brake. (Sound dreadful isn’t it)

Those potos were taken by the Sony E 3.5 / 30 mm Macro lens with Extension Ring on A7R-4 body (see a photo above, before) Right hand side image was a cloped enlarged part of the original photo left.

So, when you are lucky to have good working Ring you may get quite nice close-up photo —– especially with such A7R-4 / 62MP image sensor, we can clop the image for even higher magnification scale. (Otherwise, such as x5 ~ x10 magnification needs to have quite a hard work — and a specialised expencive Macro Lens.)

Macro shots (2)


On this post, all the shots were made by Pentax 110 Auto 24 mm lens on Sony A7R4. And looks like macro shots were the heavily cloped small part of the original photo’s part enlargement —– can you find where it’s came from ?

So, it is clear, a lens I bought for £5 from a junk box, Pentax 110 Auto 24 mm lens has the quality of the (almost) top lens, and the 60MP image sensor of Sony A7R4 can capture (almost) whole amount of those visual information there. Therefore, a wide angle casual shot of a 24 mm lens was in fact, holding the details of the macro level too.

Pretty Good isn’t it ! So, I like this Pentax 110 Auto lens on the Sony A7R4 camera always in my pocket. 😀

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. 😀

Requiem

Those screen shots of the Youtube viz was made with Canon 5D-MkIII, EF 40mm F 2.8 set manually to F5.6, 1/8 ~ 1/30 Sec’ = ISO was selected to enable this exposure.

Under the restriction we stay at home —– to spend more time with internet. = So, I encountered one of the most distinguishable, Morzart’s Requiem which was packed with the strongest anger ( = no sobbing, or asking mercy but an explosion of the anger — may be toward the God) But, mind you this recording was made 2014 —– I think the Venezuela was not in the hell (yet). And this is not my sarcasm toward the COVID-19 trouble we are having. (Timing was purely the coincidence) — but, my coincidence was always having had the message = the God may be angry.)

The musisians of this orchestra and the choir must be the ethnically the most diversified members — that’s what I noticed.

In my view, the Requiem is only a music Mozart created for himself with his true sentiment. (Others were just a commercial products to buy a favour of the society)

(Morzart said to be a member of the Free Masons though, when he died even before completion of this Requiem, nobody helped his funeral and he was buried to a common grave. — was this what he deserve ?)

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.

Magnolia by Normal lens

N50-1.2

Again, they are the same Magnolia flower but taken by the ordinary lens = Nikkor 50mm F1.2 (set at F1.2)

N50-1.2

With wide open iris = F1.2, DOF was very shallow and out of focus bokeh was such big.

N50-1.2
N50-1.2 no ext ring

And, this was really the ordinally (without an extension ring) shot. 😀

Z85-1.4

Then, those following photos were taken by the Zeiss Planer 85mm F1.4 (at 1.4 setting and with extension ring)

Z85-1.4
Z85-1.4
Z85-1.4
Z85-1.4

Zeiss 85mm has a bit smaller F-aperture but longer focul length = so that having a more or less the same DOF —– still show a bit more solid image.

Early Magnolia 2020

In this post, the photos were taken by a homemade lens Godo Lens, except no.4.
Those photos were taken by Tamron SP 90mm Macro on Nikon Z7.

I featured this flower twice (?) before using another fuzzy lenses. But, it seems the people takes the flower branch home there is no branch left on the lower part of the tree, and made me very difficult to take picture. (So, I needed to resort with something special measure. 😀 )

Those following five pictures were taken by the other homemade lens “Pla-B” Lens” —– though, with the bad weather I trid three times to get a kind of results. 😀
