Ultra Wide Angle Lens (Sony 12~24mm F4 Zoom)

I had an opportunity to test an ultra wide-angle lens, Sony 12~24mm F4 lens.  With its spec, the lens was amazingly light (in comparison to similar Nikon or Canon lens, it only half of the weight.  And smaller.)  Mounted on Sony A7R body, its handling balance was very comfortable. And function well.

Though, the image itself, the 12mm lens’ 120° view is not so new to the man using 15mm lens or fisheye lens almost like an everyday occurrence for the past 40, 50 years, looks nothing special.

Sony-12(3)-DSC06720

To make the view with a big distortion of perspective or looks more natural is not difficult at all. (in fact, it would be only few degree of the camera angle or move the position few steps away.)

Sony-12(3B)-DSC06721The lens was supposedly a rectilinear, not fisheye though, having rather prominent barrel distortion.  (Both Nikon and Canon seems to have about the same distortion) (All the pictures here showd quite of a vignetting (corners getting darker) because of they were taken with fully open F4 = so, the shutter speed was 1/3000th kind and the water splash became the dot ! )

Sony-12(4)-DSC06728

The lens said to have some measure of dust and water protection though, we better not to trust them.  Simply because, we the user will be the one who suffer with the trouble, and the service charge of the Sony is three times more expensive (Any service start with £90 deposit and another £90 for repair — even for just tighten-up a screw !)

The image which give you the impact or pressure may not necessary be created by the lens, it is simply the matter of subject or the landscape.  (You have to find the “impressive subject” first.   😀 )

But I’m not implying you to feel any impact here.    😀

(You know, it IS a joke = Ultra wide-angle or Fisheye is easy to make a joke as they can twist the view very easily.  In other words, often it is very tricky to show the natural view without any exaggeration.  Such as, that the lens can take a picture of very confined place though, it would give a false impression, as if it was a wide space.)

Zeiss – 18mm Lens for Nikon

Zeiss-18mm(1)DSC_0973

I saw this lens at Camera Cafe —– The test shot in the Cafe showed me

pretty impressive quality. Virtually no Distortion or Chromatic aberration.  

And this lens got the Number 1580xxxx,  the number of my fate. => So,

I decided to buy.  —– Lens itself is well known Distagon 18 mm F3.5 yet

this is for Nikon DSLR = FZ.2 type which has a Microchip built in and works

same as Nikon’s own lens, except auto-focus (still gives Focus-confirmation).

(Lens was designed by Zeiss but actuary made by  Coshina in Japan. ) 

Zeiss-18mm(2)557-001

From Camera Cafe, I took the direction south, on foot while shooting

time to time.— I felt the camera (Nikon D810) was working a bit funny.

= taking much longer to show the image though, I didn’t investigate it

on the spot. —– But after I checked the image on the PC, I realized that

D800 had been malfunctioning = gave all the exposure in HDR mode.  

Zeiss-18mm(3)DSC_0907

And the photo above was the most severely mal-processed one.  (straight

from CF card)  And the photo below is the normal one. (though, clopped).

For HDR mode, three images in different exposures has to be integrated

= position has to match exactly —– though, the wrong one showed an utter

dislocation of the image and the color has been red-shifted. 

Zeiss-18mm(4)DSC_0910

Richard of Camera Cafe explained that the So-called lens-mount adapter

with “Focus Confirmation type = microchip built in” often cause the

camera to malfunction. —– Though, it is too early for me to decide the

cause of this trouble.

(Whether the trouble could be repeated ? — in what condition etc etc. )

Zeiss-18mm(5)553-001

South of British Museum = Covent Garden area has many Dance / Ballet shops.  

Royal Opera/ Royal Ballet and the Drury Lane Theatre (which used to

perform “Cats” are there = Mecca of Dance.

Zeiss-18mm(6)555-001

And further walk down south => we get to the Waterloo Bridge.  

Zeiss-18mm(7)DSC_0946

And the South-bank = Art centre is over the bridge.

Zeiss-18mm(8)556-001

Zeiss-18mm(9)554-001

Zeiss-18mm(10)DSC_0969

It’s a funny installation though, as it was outside of Hayward Gallery,

it must be an art. —– is it ?  —– You got to be serious !    🙂  

Zeiss-18mm(11)DSC_0948

—– So, optically superb.  Electronically —– not sure.   

I need to test this 18mm lens further.
