The catalog for the upcoming Tamron 18-300mm f/3.5-6.3 has now been shared by nokishita. You can find it down below.
According to the catalog, the release date for the Tamron 18-300mm f/3.5-6.3 should be September 24 for the Sony version. It’s a bit confusing if also the Fujifilm X mount version will be released by then, as it is written “to be released”.
You can find the lens listed here at BHphoto.
Virtually all cameras of the Fujifilm X series are ISO-less (also known as ISO-invariant). This refers to cameras with sensors for which the ISO setting doesn’t matter in terms of image quality. Only the set aperture and exposure time (shutter speed) are decisive. It’s all about the actual amount of light that reaches the sensor. I have written about this before (German version, English version).
You can find out yourself to what extent the sensor in your camera is ISO-less. Here’s an example with a GFX 50S: I first shot a consistently lit test subject at f/13, 1/50 sec. and ISO 1600. The result was a correctly exposed image. I then shot the same subject again at aperture 13 and 1/50 sec., but this time I reset the ISO to ISO 100. This is the base ISO value of the GFX 50 series, i.e. its baseline sensitivity. Of course, the second image appears four stops darker. After all, it was taken at an ISO setting that was four stops lower than the first shot, with otherwise the same exposure. To make our second image (captured at ISO 100) appear as bright as the first, we need to boost it four stops in the RAW converter (in our case, that’s Adobe Lightroom). This we do by moving the converter’s exposure slider 4 EV to the right from its zero position.
The same subject shot twice with f/13 and 1/50 sec. – on the left with ISO 1600, on the right with ISO 100 and a subsequent brightening in the RAW converter by 4 EV.

To better assess whether the GFX 50S used in this example really works ISO-less, let’s take a closer look at enlarged details of the two test shots:
FujiRumors told you already back in March (!!!) that Fujifilm will launch the Fujifilm GFX50SII.
And over all these months, we have leaked, price, specs, release date and more.
We have also told you that, along with the Fujifilm GFX50SII, Fujifilm will launch a new and affordable zoom lens, the Fujinon GF35-70mmF4.5-5.6.
When we leaked the first details (no aperture ring, $500 kit price, etc), some FR-readers were sure that this would be the G mount equivalent of the Fujinon XC lenses, hence just a plastic mount and possibly not even weather sealing, in order to keep it as cheap as possible.
But that’s not correct.
The Fujinon GF35-70mmF4.5-5.6 will have a metal mount and, that’s today’s rumor, according to our sources it will also be weather sealed!
Fujifilm and Cosina managers have met for a discussion about the development of the new Voigtländer Nokton 35mm F1.2.
The video has been shared on youtube, but is only in Japanese. However, the Japanese website dclife reports about its content here, so you can let it go through google tanslate here. There is not much to discover, but here are some main ponts.
Also, dc-watch has posted the first review about the Voigtländer Nokton 35mm f/1.2, which you can find at dc.watch (translation Part 1 / translation Part 2).
In short: it’s soft at wider apertures, distortion is well controlled, good uniform bokeh and 3D effect.
