Fun lens on the Alpha 7R

Alpha 7 Fun lens(1)- 713-001

Picture here is a kind, nobody would be impressed, still nobody

would complain kind.  It was made by a lens of rather humble origin,

came from discarded toy camera. —– Considering it’s utterly cheap

existence (two plastic lenses structure) the picture isn’t too bad at all.

On the time, people see the picture on the 5″x3″ chemist print,

this kind of quality was perfectly acceptable.

Alpha 7 Fun lens(2)-A09A6544

In fact, I’ve talked about this lens, few post ago.

Alpha 7 Fun lens(3)-001

And now, the lens has been properly (in certain extent  😀 )

re-structured for Alpha 7 camera. (Beautiful isn’t it ?) Ha ha ha.

(So, the lens can take landscape to portrait without refocusing

or change F-aperture kind = anyhow, no controls here at all.)

Alpha 7 Fun lens(4)-001

Only the trouble I found with this combination was = mysterious

blurred image they makes.  It was under a blight day light. 

The AUTO setting on the camera, A7R chose ISO 1600 and

shutter speed was  1/160.  

Alpha 7 Fun lens(5)-001

Why the picture was blurred ? — I set up a tripod (not a heavy weight,

still proper Gizzo tripod) — strangely, still the picture was blurred. 

It was nothing but a mystery.  (Obviously, I need to test further though,

at moment, this IS a lens (other than Pinhole) I got for this camera.

(I’m waiting to receive lens adapter for this camera.) — Whether this

body got a resonance to  1/160 shutter vibration, or the camera activating

other function to cause adverse effect ? = So, I tested the camera on

manual setting :  ISO 3200-1/320, ISO 1600-1/160, ISO 800-1/80,

ISO 400-1/40, ISO 200-1/20. Iso 100-1/10, Iso 50-1/5.  All hand-held.

ISO 3200 - 1/320

ISO 3200 – 1/320

ISO 50 - 1/5

ISO 50 – 1/5

Those photos above were the shot on the test.    Non of them

showed heavy blur = it seems, the AUTO and  1/160 combination did

the Blurring business.  😀   — on the AUTO setting, other function

of which I’m not fully understood the implication, meddling in.

(Such as when the A7 thought, the image is too high contrast, the

automatic HDR operation comes in = gives three consecutive

exposures = unexpected hand may not keep still.)

I guess, something adverse effect of AUTO might have had happened.

It’s still a mystery Sir.

To be fair to a Paying Customer, this is the quality if you pay the price.

This photo was taken by  Canon EF 40mm F2.8  on 5D Mk-III

— can you see the difference ?   (It’s costing  £100 more.)
