Last month I reported about a not yet announced 7Artisans / DJ-Optical 50mm f/1.0 mirrorless lens that appeared in one of the promo pictures (see this and this post).
I contacted the manufacturer directly and they confirmed that they do not have any plans to release such lens. They will be however releasing a new 7Artisans 35mm f/2 rangefinder coupled lens for Leica M-mount – see this post for some pictures of the new lens.
After ten years of effort to convince the astronomical community about the benefits offered by curved focal planes, the activity is now ongoing around the world, with academic developments at ESO, Stanford, MIT, but also at the industrial level with recent realizations from Sony and Microsoft.”
It is clear that curved sensors are mainly going to be first used for astronomy and it will be a while before (if ever) you see them in your local camera store.
Curved sensors have several advantages and benefits including requiring smaller/faster/simpler lenses and overall better corner to corner IQ (curved sensors provide correction of field curvature):
A curved CMOS sensor has a few advantages over a planar sensor, Itonaga said. Because of the geometry, it can be paired with a flatter lens and a larger aperture, which lets in more light. Photodiodes at the periphery of a sensor array will be bent toward the center, which means light rays will hit them straight on instead of obliquely. What’s more, the strain induced on a CMOS sensor by bending it alters the band gap of the silicon devices in the sensor region, lowering the noise created by “dark current” — the current that flows through a pixel even when it is receiving no external light.

Additional info on the Voigtlander APO-Macro Lanthar 65mm f/2 Aspherical E-mount lens:
The Voigtländer MACRO APO-LANTHAR 65mm F2 Aspherical was announced at Photokina 2016 in Cologne, Germany, as a reference exhibit. Since then specifications and appearance have been improved. The Red, Green, and Blue lines on the lens barrel proudly indicate its heritage from vintage APO-LANTHAR lens designs – High Performance. At F2, this lens is one of the fastest macro lenses available for full frame format. Macro Ratio is 1:2. Minimum Object Distance is 31cm.
Here are two hands-on videos of the lens from the 2017 CP+ show:
An update on my post from last week – it is now official: the lighting manufacturer Bowens is going out of business. In a statement today the parent company Aurelius Group confirmed the news:
Aurelius said the decision was due to the “the far-reaching changes affecting its market, including new, considerably less expensive products by Chinese manufacturers, product innovations by competitors, and the changed buying behavior of professional photographers, who are now only willing to invest in new equipment if the investment guarantees additional income.” (via PDN)
Until last year, Photokina (the biggest photo show in the world) was taking place every other year in September. Back in May, I reported that Photokina will start taking place annually starting from 2018. We now know the exact dates for the 2018 and 2019 Photokina shows:
