Fragmented lens for London snap (A)

Somewhat the same landscape by the “Fragmented Lens” on Nikon Z7.

It is something puzzling me ? ? ? —– Advanced image processer in the latest camera straggling with unusual images and make the image even more unnatural.

.

F and M — Cats story ?

They are the photos from the Fortnum and Mason’s X’mas decorations taken by a homemade “Fragmented Lens” ( few exceptions which got dark surroundings = 110 Pentax 24mm Lens) on Nikon Z7.

I’ve been seeing this gentleman always on this doorside every X’mas time (except last year) = he is the another fixture of the Fortnum and Masons shop for ages.

I’m not knowledgeable enough to tell what breed of the cat they are nor able to tell about those angels —– still, I hope you to have a peaceful merry X’mas. 😀

Oxford Street —> Selfridge X’mas decoration (?)

The all photos here were taken by a homemade 1/4 lens on NikonZ7.

Selfridge’s this year’s X’mas decoration was just the display of their goods.

Economical downtern reflected from uncirtainty of the Brexit etc etc might be making shy economy, hence their design were pretty economical here too.

1/4 Lens for London

They are the snap shots by the 1/4 Lens on the Nikon Z7 —— colour balance was automatic ( B/W effect was not intended = just happened)

By the way, this is Downing Street — over there the Number 10

Incidentally, it was not the end of the world. 😀

Hi-ISO noise

Fragmented lens on Nikon Z7 / ISO 25600 / ND filter = in order to make the exposure time even longer, a dark ND filter was used as well.

Till now, I thought that the noise caused by Hi-ISO setting was just a nuisance, or necessary evil though, I became aware, in certain case, it could be an useful tool.

(ISO represent the degree of amplification of the signal —– any electronic signal would produce the noise when it was intensively amplified = whether it was audio signal, or light signal from the image sensor, when they were amplified, the residual charge in the circuit line etc etc were also amplified hence those noise was superimposed onto the main signal. — you may say why the digital signal has noise = the output signal of image sensor IS analog, until they were AD converted. = Here, in the AD converter, the depth of 12 or 14 bit etc decide the quality of the image. = one bit more mean twice as much process will be needed for each pixel of the image sensor ! = You see how enormous the task is = That’s why almost all digital camera is Japanese (inside of Leica is Panasonic) and almost all image sensor is Sony —– Who else would bother to take such awkward task in the world. 😀 )

Fragmented lens / ISO 25600 / ND filter

Fragmented lens / ISO 25600 / ND filter

Fragmented lens / ISO 25600 / ND filter

W 1/2-B lens / ISO 25600 / ND filter

For a comparison, this photo was taken under the same condition but with the Sony A7R / Fragmented lens / ISO 25600 / ND filter (noise level seemed to be a bit less than the Nikon Z7 —– was that what the advantage to be an electronic company over a lens company ? )

Even among the oil paint, many different styles = so, in the soft paintery effect photography, there could be a grainy style —– looks not too bad.

Morning Sky – Dec’19

10 Dec’2019 07:32 Zeiss Distagon 18mm F3.5 on Nikon D850

07:02 D850-18mm

07:18 Fragmented lens

This one was by the Fragmented lens on Nikon Z. (Camera itself set the ISO to 12800 (not me) = So, the noise was too high — still, as an image, it wasn’t too bad. Unlike a soft smooth image, the roughened up texture showed quite strong impact. I like it.

07:20 W lens-B

This image was too murky though, that was what this homemade lens was made for.

07:20 110 Pentax-24mm

07:21 Fragmented lens

07:33 D850-18mm

Only a decent lens in this post = Zeiss Distagon —– costed me a bit. 😀

07:41 1/4 lens

Small part of disposable camera lens makes not too bad image !

07:43 110 Pentax

This Pentax lens itself IS a pretty good decent lens, even if it was for 110 size camera but mounted on a full size mirrorless Nikon Z.

We can take picture in any excuse. Nothing hinder us to be creative.

.

1/4 lens !

After two attempt of two 1/2 double lens, it would go to even 1/4, naturally. (Anyway, it was only a matter of hacksaw and a glue work. And it was what an Otaku lives for. 😀 )

Photo left = Covering the lens with black tape and see the effect = even from a small part of the lens, good enough image would be created. Photo right = so, only 1/4 of the lens to produce the main image and 3/4 lens for the out of focus bokeh.

The plastic lens was mounted to the Sony A7R camera (yet the lens can be attached to the Nikon Z as well.)

So, this homemade lens will produce the image even worse than those W-lens A or B ! 😀 —– can you guess how happy I am. Ha Ha Ha 😀

So, they are the regular test shot. (This dry rose has been working for me the past 5 years !)

In case, if anyone wanted to see more natural image for a comparison, those are the images from the ordinary (?) 110 Pentax 24mm lens on the Nikon Z.

Fall or fallen

I’m still using Canon 5D-MkIII — for indoor copy work etc. So, this one by their 40 mm lens.

But, this one by 110 Pentax 24 mm with extension ring on Nikon Z7.

To annoy you, this photo was by W lens-B on Nikon Z7.

By W lens-B

By W lens-B with extension ring.

Also W lens-B with extension ring

By 110 Pentax 24 mm lens with extension ring

Also by 110 Pentax 24 mm lens with extension ring

They are rather lazy shooting. Sorry. 😀

Aster aster

In anywhere, the Aster seems to be a flower of the Autumn. There said to be many variety of Aster though (one of them said to reach 2 m tall) to my eyes all the Aster looks identical.

And Aster is one of the most humble flower, almost come down to a weed. = almost, yet she was not common enough to be a weed.

Photo left was taken by W lens-B and right was by 110 Pentax 24 mm lens on Nikon Z7.

So, the same question, why I see the same flower on the same spot every year —– why I don’t see a bit different variety ?

In Japan, this flower was always seen to be a synonym of the pure innocent girl. (now, it must be a rare, or even endangered species = so, the flower receiving even more isolated romantic dream — of a boy)

.

W Lens-B

Thanks to the advancement of the technology and the use of the image recognition system etc, alongside the advancement of the optical design x optical plastic = we may find many usable aspherical lens in many devices.

So, I got a plastic lens and I made yet another W lens for my camera. —– using the same idea of 2 cutted half lenses put together.

The effect was more or less the same to W Lens-A but the bokeh is a bit more prominent.

Basically those lenses were designed for omnifocus, yet still a close-up extension ring works well. (omnifocus works only within a limit) 😀

Whether you like them or not I don’t care. I’m quite happy with them because, I feel that the image is much closer to what I’m living with. 😀
