Sigma Keeps Teasing Fujifilm X Mount Lenses

Share

Sigma has teased Fujifilm X mount lenses in the past:

And apparently they do not stop here.

In fact, when recently asked if there will some lenses for Fujifilm, Sigma answered on their social media:

I expect that they’ll be on Sigma’s radar going forward.

The difference to the past is that this time they did not give any time indication (2021). Maybe the worldwide shortage of chips has forced Sigma to change plans and move the release back to 2022?

On the good side: they don’t say “hopefully” we will see Fuji X mount lenses coming (as they did in the past), but they “expect” them going forward.

2021, 2022, we waited so long that at this point it does not make a massive difference anymore. Just give us Sigma X mount lenses in not so distant future ;).

Tamron 18-300mm f/3.5-6.3 Lens Catalog Online and Release September 24 (for Sony only?)

Share

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.

7Artisans 25mm f/0.95 First Review, Product and Sample Images

Share

Just yesterday we reported that 7Artisans is about to release the 7Artisans 25mm f/0.95 lens for Fujifilm X.

After my article, a FR-reader reached out to me (thanks) and directed my attention a website called schlueter-enterprises, who has already shared sample images, product images as well as an initial review about this lens. I will share the link to everything down below. Now here just some main points and images.

  •  build quality of 7Artisans 25mm f/0.95 lens is fully in line with the high end quality finish of 7Artisans 35mm f/0.95 and 7Artisans 50mm f/0.95
  • smooth damped movement of the aperture and focus ring
  • 11 lenses in 9 groups (3 lenses are made of high end HOYA ultra low dispersion glass)
  • a bit front heavy on X-Pro2 due to 99.7mm length and weight
  • filter diameter of Ø52mm
  • without lens hood the IQ is already high [admin note: he still needs to get a proper lens hood for this lens]

The GFX 50 Series is an ISO-less Classic

Share
The sensor in the GFX 50 series is certainly not the fastest. Nevertheless, you should not underestimate this ISO-invariant classic with its 50 megapixels. In terms of sharpness and dynamic range, it can still hold a candle to newer developments.

by Rico Pfirstinger

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).

Is My Camera ISO-less?

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.

Please click on the image for a larger version.

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:
