When it comes to 14mm fullframe lenses, Sigma likes to break records. The Sigma 14mm 1.8 DG HSM Art was the fastest 14mm lens for DSLRs when it was released in 2017 and this Sigma 14mm 1.4 DG Art is the fastest 14mm lenses for mirrorless cameras since 2023. This lens’ purpose is obviously astrophotography and on paper it is the ideal lens for milky way and especially aurora shooting. By my experience these fast ultra wide angle lenses have very high sample variation though, did Sigma manage to solve that issue? Let’s find out in this review.

Review: Sigma 35mm 1.2 DG Art II

Released in 2019, the original Sigma 35mm 1.2 Art DG DN was the first 35mm 1.2 AF fullframe lens. It took until 2025 for another manufacturer to challenge Sigma by releasing a 35mm 1.2 lens with autofocus of their own. Actually, there were two at almost the same time: Nikon with their Nikon Z 35mm 1.2 S and Viltrox with the Viltrox AF 35mm 1.2 LAB. It seems Sigma saw some room for improvement, as in late 2025 they released an updated version, this Sigma 35mm 1.2 DG Art II. On paper it is surprisingly lightweight and small compared to its predecessor, but what about the optical qualities? Let’s find out in this review!

The year 2025 was the year of the 35mm 1.2 fullframe lenses, as we saw Nikon and Viltrox releasing their first lens with these specifications and Sigma updating their original 35mm 1.2 Art lens from 2019, releasing a completely overhauled second generation model.

How do these lenses compare? Where does the more affordable Viltrox lens stand compared to the lenses from the reknown manufacturers from Japan? Let’s find out all that and more in this comparison.

Analogue Adventures – Part 55: Kodak Ektachrome 320T (expired)

As already pointed out: in 2025 no one makes slide film faster than ISO100 anymore. And no one makes slide film to shoot under artifical light (“Tungsten based”) anymore either. That wasn’t always the case and from 1992 to 2003 Kodak offered this Ektachrome 320T, a higher speed tungsten based slide film. These have all long expired, but thanks to our readers I got my hands on a roll. Let’s see what we can do with it.
Processing (E-6) was done at ProLab in Stuttgart, scanning was done by one of our readers via a DSLR. The pictures you see in this article are from one roll.

During their EX era Sigma released two f/1.4 primes, the Sigma 50mm 1.4 EX HSM and this Sigma 85mm 1.4 EX HSM. The 50mm is a lens that can still be interesting today due to its good sharpness, appealing bokeh and very low price. Will the same hold true for this 85mm lens as well? Let’s find out in this review.
