In reply to:

TheSimpsons: Can I use this to archive my most treasured digital to film? We know film lasts atleast 100 years. Discs tend not to , CDs may, DVDs may etc but the devices to read them ? And as a last resort with film you can unreel it and look thru a lens ( as I did when at age 12 Mum could afford a Cini camera for my birthday, but we couldn't afford a projector) Those films from 50s and 60s still good , but my video8 Hi8 ... ?

Did you check the splices at your 50s and 60s rolls recently?
With films, it's all about chemistry. Glued positions will split, colors will fade, film material will get embrittled, layers will stick together, not to mention the problems of fungi, dust, bacteria, projectors' oil wil become resinous e.a.

Nature is the best actor. Admirable footage!

PowerG9atBlackForest: You wrote "launched December 25th, 1998, when some of our staff were still in elementary school"...
So good to hear that some of your staff actually visited an elementary school ;-)
Should that remain unclear, well, it was meant as a joke. Sorry, I could not resist the temptation.
Thanks for alle your very good work!

Addendum: As experts, you should have known that not using a wide-angle lens for the group shot would have been wise in order to be fair to those who stood on the edges ;-)

maxnimo: After 1000 years new bags still keep coming and coming. How many more centuries before a perfect bag gets invented?

Are you married? Your wife may give you the answer, or rather not.

In reply to:

nimrod1212: I'm surprised this hasn't been attempted already. Not only vignetting would be improved.

@ speculatrix, Tons o Glass o Class: Well now and in short, because a curved sensor may show a higher sensivity (amongst other properties), the patent is about curving just the edges of the sensor in order to help with problems of vignetting?

As a rule of thumb: Don't rush in; let others be the guinea-pig.

What more?? I can't see that laws of geometrical optics should support such an idea. Of course, lenses could be designed to deliver a curved image (resulting then in different aberrations) rather than an image on a flat plane. But: Firstly what for, and secondly how could that possibly improve vignetting?

PowerG9atBlackForest: Am I just too naive? An SD card is some sort of a SSD; the price vs. capacity ratio is quite good, it is tiny, and it connects directly into the camera and PC.

Thank you!

In reply to:

PowerG9atBlackForest: Looking forward to their 7.5mm/F2 MFT lens.
at Damien: Only one sample F2.8?

At Crazie Nikonian: Please, do learn about distortions.

There is distortion caused by lens errors as a consequnce of an insufficient lens system correction. Venus optics did a very good job in eliminating these by applying an optimum of efforts in the lens design. This is why straight lines in reality will remain straight lines in the picture, e.g.

There are also those sorts of distortion arriving due to the principles of how photography works, i.e through central perspective. Take keystone distortion as an example. Or take your 2 cans of soft drinks; they as well as people's faces or bodies placed at the outer parts of the picture simply and inevitably will suffer from that effect; such sort of distortion cannot be corrected. Keystone distortion can.

Nothing to "cough" about!

D Gold: DPReview,

Any idea how coma is handled with this lens?

LOL.
One hint: Have a look at the MTFs and you might be able to get an idea how astigmatism will be handled. From there, it's not far away to coma.

This is why it would be so interesting to see a few more examples at F/2.8. At Photokina 2016, I only took photographs using the Laowa 7.5/2.0 MFT wide open.

old_slowhand: Just had the chance to hear a lecture of Dr. Kaufmann (ex CEO and big shareholder of LEICA) last Friday on a Congress. Believe me, these guys know exactly what they are doing ;-) This is why they survived (after standing of the verge of bancrupcy) and e.g. Kodak did not. Don#t let the superficiality of this red lens fool you...

They did not yet arrive, they are still going. Should I say "straying"?

Michael J Davis: Lovely - my sort of photos!
But why do you call "gasholders" - "gasometers" ? - it has nothing to do with metering!

entoman wrote: "... what has this got to do with ... the photographs?"

Everything, because Belgian photographer Reginald Van de Velde, in his imagery, he searched for patterns, a sense of scale, repetition, and disruption, rendering landscapes within the massive structures. He wrote: "... One thing that fascinates me extremely is the fact that not a single cooling tower is the same. Each and every one of them has a unique interior design and build! They all look the same from the exterior, but with each visit to a new cooling tower I’m always surprised by a different interior, time and time again ..."

Alas!
