A7 doing Good Job or just Meddling too much ?

A7 ETC TEST(1)-_DSC2593

Quite a while, time to time (I don’t remember how many years)

I’ve been taking picture of the sky from my window.  Naturally, its

looks changes season to season, and it’s not necessary a dramatic

beautiful sky.   It’s just a sky.

A7 ETC TEST(2)-DSC_2714

As I don’t go out for drinking or look for a bottom of the girls,

watching the sky is a healthy alternative (and cost nothing.)   😀

A7 ETC TEST(3)-001

Not just watching but taking photo mean, by a camera.  

So that, my Nikon with 18mm Zeiss lens has been a fixture on front

of the window quite a while.   And, — as I got Sony A7 and the adapter

to fit a Nikon lens to its E-Mount, I tested its 18mm lens on the A7 body.

—– though, the sky over dence leafy tree is a very contrasty image =

to the SONY camera.  (Canon 5D or Nikon D810 just take as it IS)

But, A7 is keep meddling (— are they try to brighten the dark shadow

of the tree ? — how do they know what image I want to have !)

DO they believe that they can make it for ME ? — how patronizing.

— should I say,”Thank you very much” OR “Silly YOU, stop it”  😦

A7 ETC TEST(4)_DSC2379

Exactly the same trend to “Smart Phone” with hundreds of the

Fancy App,  Sony can do many tricks, such as the Panorama here.

(Above was a part of 18mm — 360 degree Panorama

— in my kitchen)  😀

A7 ETC TEST(5)_DSC2394

And this was a Panorama made by a 16mm Nikon Fisheye lens

(vertical line shows no distortion !)

— may be a fun to some user though, I’m very sceptic to those

too much Digital intervention.    It’s rather spoils the spirit of

the Photography than enhance it.   Spending more time gazing

 at the PC screen, than to stand against the subject = we are

going into more and more virtual environment and

losing the real touch of the life. 

—– And to the camera company themselves, = if the digitally

stiched-up photo is good enough, who need to buy expensive

wide-angle lens ?


Useless Information (?)


Image here was made by a Tri-color Pinhole which I could mount on

the A7 camera through Nikon to EOS and EOS to E-mount adapter. 

(What a hustle ! = I’ll tell you later.)

During all those hustle, what I found were — (though they may not

necessary useful to you.)    😀


1)  You can use Pentax-K lens cap on Nikon lens. (Photo Left) 

2)  Likewise, the same Pentax-K  lens cap will fit to the Sony

E-mount lens. (Photo Middle) 

3)  Sony E-mount body cap will fit to the Nikon body. (Photo Right)


4)  The adapter, EOS to E mount I got from Ebay (about £5 or so) had

a trouble — as bayonet spring was too wide and obstructing the lens

bottom goes into = I needed to file-down the width of those 3 springs

(where I marked in Red on the photo Right = see enlarged


(Photo shows the bayonet spring and a broken hence replaced screw)

= If you found the same trouble, you need to do the same — or buy

another, more expensive one. (So, they changed the price to £7.xx) 😀

(Think, why it was cheap = being defective, it became a deadstock and

sold as a scrap.   Then, Chinese guy made a Net business to sell away

= how many customers sending back and claim a money back which

would cost more, and the address may not even existed.)   😀

The funny story was, as I put negative feedback on ebay, the seller

contacted me saying if I change the feedback to positive,they will

refund me, so I replied them “As this blog explained, I’ve modified

its defect and now I’m using it, therefore no need of refund, still,

the fact remain I wouldn’t change the negative feedback” —

then, they send me yet another mail

“We will send you £2,  so change the feed back to positive” =

Are they thinking that they can buy me £2 ! = What a mentality !

Is this a norm in China ?   horrifying isn’t it ! 

To see the situation, I gave a through check of those adapters.


(To be fair, I obtained even one more EOS-NEX adapter)


In order to make a bayonet fixing tight enough= not clutter,

still smooth enough to dismount, the spring was used beneath

the craw (such as the one I’ve shown few picture before with

red mark), other cheaper alternative is to make a slit in the

claw (Photo above Left = yellow marked) and make the slit

bend to give some flexibility.    Though, the other EOS-NEX

adapter showed funny character = Canon’s EFS (plastic mount)

could be mounted but metal mount thousand pound lens couldn’t. 

Because the adapter’s female claw was too thick.  ==> I needed

to file down the claws thinner. (Photo Right — with blue color

marker =  it’s easy to see where I do need to cut !)

(It’s funny to discover, that the Canon is making their

cheap EFS lens mount even thinner and loose.)


5)  Nikon G to EOS adapter sold on the Net, the rotating lever may be

too long and stack with the lens bottom.  So that, if you found the sign

of such symptom, DON’T mount the lens to EOS with such adapter.  

You need to file-down the tip of the lever (marked in Red in the

photo above) a bit shorter, and make sure the lever moves freely.

So, — after I’ve sorted out those troubles, I could mount my

Tri-color Pinhole (here, Pink, Yellow, Sky)  to the A7 body.

( Then after thought, I should make another one for A7, since an

Olympus body cap which is fit to A7 is  £0.99 and etc is free, but

the use of those adapter which is costing £5, £10 makes no sense.)


And, this was the photo of, now rather familiar view — by

the Zeiss Distagon 18mm, designed for Nikon mount.

—– A nightmare of the mount adapter IS = once the lens stack

to the body, there is no way else other than to destroy the lens.

(Pull-off the screws, fixed to the mount with sheer force or hack-saw 

the lens bottom while showering the camera with saw dust.)

Is it funny ?


PS :  If you are looking for the Body Cap for Sony NEX mount to use

for a Pinhole experiment etc. or just for body cover, now in the Ebay

you can find the pair of E-mount (NEX) Rear Lens Cap + Body Cap

for £0.99 —– you don’t need to hastle finding out OM cap.   🙂
