Vest Pocket Lens on A7R

Vest'P(1)-DSC09764On here, the images of Vest Pocket lens from the field test.  (Give a close eyes to this photo and see how the details and rich tones are there ! —– by the way, the image looks a bit more greenish on iPad screen.)

—– If the image looks fuzzy, the lens was fully open (F6.6).  (But mind you, the original Vest Pocket camera’s image was 6×9, therefore we are only seeing its cropped center here.)

Well, Vest Pocket lens on the Sony A7R was the camera who took those photos though, behind of those, there were many more minutely blurred photos, seemed to be caused by the wobbly lens structure.  Otherwise, some photos were amazingly sharp, considering that they came from such old single glass lens !  (And it would rise a very serious question, that is, the great effort the manufacturer spending to create 10, 20 elements lenses using ED glass etc, what sort of practical significance was made ? —– of course, unless otherwise, there couldn’t be such as 14mm F1.8 lens or 18mm~400mm Zoom etc etc still, —– ? )     In reality, often, those expensive technical samples were made for demonstration purpose and made only 100 or so to display in their showroom.  In contrast to the millions of  18~55mm plastic kit lens.  Funny fact was, even after the people was made to believe that “the Larger the Better” myth suddenly changed into iPhone camera. —– It indicates that, so-called fine sharp image might be just a formality nobody actually bother. )
