1^st Post

I have been dissatisfied with the rendition of my 24-70 VR, For a week or so have I been trying all sorts of tests ,so yesterday ,D3s with the 24-70 VR perched on a tripod ,during a gruelling test, with VR set to Off...Normal...Active..with different apertures..shutterspeeds..distances...the Inevitable happened,..

As the rig was mounted by means of a cheaply bought copy of an ARCA -SWISS coupling , I managed to trip the tripod , yet , hastly prevented it from toppling over when the cheap knock-off lost its make-belief grip ,and the rig bounced on the wooden kitchen floor....

The world had come to a standstill...and in a flash , Eric`s " tale of woe " of his 24-70 on a D3 that were sailing down some stairs came to mind....as in a nightmare I carefully inspected my precious, and all seemed to be fine...after a coffee sipped with trembling hands, I resumed the testing, and the photo`s are good !!...what seemed to be a problem was no more.

Later on, I remembered having read somewhere that VR can get Stuck, and when that happens , quality is Impaired, the remedy is then to tap the lens gently, yes, I had suspected that being possible as I had bought the 24-70 second hand, and have been tapping the 24-70 , but without any difference to see.

But a Severe Tumble on a wooden kitchen floor has done the trick it seems ,yet I sincerely hope that not ever to happen again.

It is something that I do not wish on even the worst of an enemy.

It is something that I do not wish on even the worst of an enemy. Thanks for that. Glad it didn’t fly into 6 or 7 pieces like my 24-70…although it was easily reassembled and it too worked better after the fresh air got into it. (I suspect the technician at ACS did a more precise calibration/ lubrication job)

I am now off to whack the living daylights out of one of my Sony lenses which is underperforming…..

…..although I may need to punch myself in the face if it makes no difference and I need to look elsewhere for the reduced quality.

I have been going back through my archives thinning them out! Whilst training on a Mac and defamiliarising myself with Photoshop after a 5-6year break using Affinity Photo. One thing that strikes me is how good some of the images look on a variety of cameras over the years. Sure if you zoom in and pixel peep you can see that the definition/resolution isn’t quite as sharp as the latest camera BUT the image as a whole still looks good.

It reconfirms my belief that if the original composition, subject interest, lighting and technique are solid….the camera / lens used is of lesser importance.

quote ; I am now off to whack the living daylights out of one of my Sony lenses which is underperforming…

So,the Sony ( ZEISS ? ) lenses do have VR build -in as well ?..thought they have that build-into the camera ,or in Both perhaps?

Could it be the software ..or is it just the one lens ?

Camera calibration is Incredibly Important I have been told, and we are talking Digital( software ) focusing among other anomalies.

Let us know how you are getting on, seems that the more complex the equipment has become, problems follow suit in complexity.

Sony knows all about quality lenses I had 30 years of working with Sony broadcast top-quality video cameras all pin sharp and the latter ones had autofocus that never lost focus. I now have 5 Sony lenses with my Sony A1 and they can not be faulted in terms of sharpness, image quality, and spot-on autofocus. The A1 also does very good x4K video and first class steady handheld shots.

There is no question about SONY`s expertise with the digital imaging industry, after all, they made the first true Digital cine camera in conjunction with Industrial Light & Magic - PANAVISION - with SONY manufacturing the camera that was used to film the entire " Return of the Jedi ".

I have seen that camera overhere with an ANGENIEUX zoom on it,...begs the question...after their take-over of KONICA-MINOLTA, who makes SONY lenses ..the answer is not clear to me, as with the Pro-camera`s lenses of different manufacture are mounted, PANAVISION .. ANGENIEUX..and I have even seen a COOKE lens mounted. ( Expensive Buggers them are, 22000 pounds for a prime lens...makes even SCHNEIDER glass look cheap ).

But on the semi-pro ones do I see SONY engraved,some ZEISS , so who makes those then, do you know ?

They did have a cooperation with Zeiss where Sony used some of their technolog hence the badge recognition…but the lenses I thought (again) were still made by Sony???

I was only joking about whacking the Sony lenses….like Graham I’ve not had any bad results from any of their lenses and they do seem very much to be in sync with the camera functionality.
