Lens Comparison (2)

Z-18mmThis photo — by the Zeiss 18mm F3.5 on Nikon D850 / ISO 800, 250th Sec —– (All the photos in this post were cropped only in its hight, and the width were kept as its original to show the relative angle of view of each lens —– for example, after the widest 18mm, next wide image was shown here by the Fun lens, which was originally an one-time use panorama camera and the viewing angle was the 35mm equivalent of 27mm lens.)

Seeing the same old sky, I took the picture of the same, with many different lenses —– and made more or less the same images.  😀

Comp(2)-A09A8019

Still, they are only a half of my homemade lens stocks.  (It’s annoyed myself a bit) 😀

Helic-BThe first of this operation was, the Helicoid (B) with a setting of ISO100, 650th Sec —– since this lens has the brightness about fully open F2.2,and 2.2 only = no iris = needed to use lower ISO.

FunBy the so-called Fun Lens / ISO 100, 15th

Helic-ABy the Helicoid (A) / ISO 100, 320th

G9By the G9 lens / ISO 100, 1250th

DD-PinBy the Double Density Pinhole / ISO 6400, 250th

G10By the G10 lens / ISO 50, 640th

MagBy the Mag lens / ISO 50, 650th

Son-30mmBy the Sony 30mm F3.5 / ISO 50, 500th —– I can not stop thinking, what this “sharper” image can give us, more than the other fuzzy images ?

SZ-55mmBy the Sony/Zeiss 55mm F1.8 / ISO 50, 2000th (It seems something wrong with this lens’ focus = even with manual setting, the lens moves away when the shutter was pressed = may be that’s why it was offered so cheap. (and lots of them in the Ebay)   😀 

Koda-Red100 years old Kodak lens (equivalent of 175mm F10 / ISO 400, 500th —– as a 175mm telephoto lens, the image was quite good, especially considering that the lens consists only symmetric 2 glasses, that’s all ! )

Koda-FunBy the Koda-Fun lens / ISO 50, 4000th

SZoomBy the SZ lens / ISO 50, 1250th

OmuniBy the so-called Omuni (focus)lens / ISO 50, 1250th

More or less the same fuzzy images though, still got each character.  It’s not too bad to play with those lenses.  (Anyhow, they didn’t cost me much — still gave me a lots of fun)

Morning SKY – 18

N_SKY(1)-DSC_0357Took on 18-01-2018/02:41   (This photo got funny reflection of the room)

England was having only +9° weather and severe gale force wind, nevertheless the life goes on and as usual, still, a morning is keep coming.

N_SKY(2)-DSC_0358/6:45 (ISO 800, 2 sec)

Looking out the window, I noticed rather fancy sky.   (Except the last photo, all the pictures here were taken by a Nikon mount Zeiss 18 mm lens / on AV mode)

N_SKY(3)-DSC_0359/6:47 (ISO 800, 2 sec)

On front of my eyes, the Sky changes minutes by minutes.

N_SKY(4)-DSC_0360/6:49 (ISO 200, 6 sec) —– When those 6sec exposure occurred, the camera was hand-held, while the top of the lens was pushed against the window glass.  😀

N_SKY(5)-DSC_0361/6:54 (ISO 200, 6 sec)  (Notwithstanding its hand-held 6 second, the picture was surprisingly good. —– don’t you agree ?)

N_SKY(6)-DSC_0363/6:56 (ISO 200, 6 sec)

N_SKY(7)-DSC_0364/06:59 (ISO 800, 1.3 sec)

N_SKY(8)-DSC_0365/07:01(ISO 800, 1 sec)  (The light in the each picture was a different aircraft —– so many of them flying)

N_SKY(9)-DSC_0366/07:09 (ISO 800, 1/3 sec)

N_SKY(10)-DSC_0368/07:32 (ISO 200, 1/20th sec)

N_SKY(11)-DSC_0372/08:04 (ISO 100, 250th)

N_SKY(12)-DSC_0374/08:33 (ISO 100, 640th)

At last, the sun came out.

N_SKY(13)-DSC_0375/08:36 (ISO 100, 80th)

N_SKY(14)-DSC_0376

(Only this picture was taken by a homemade G9 lens on Nikon D850.)

Well, they may looks all same.  😀       The shot by a homemade G9 lens on Nikon D850.     A kind of mystery was that D850 recorded this lens as a 50mm F2 lens = it’s more or less correct  (F2.5 was more likely figure though) —– How they found this ? ? ?
