Sigma 20-200mm 3.5-6.3 DG Contemporary on Sony A7rII
You haven’t seen (m)any reviews of superzoom lenses on this blog so far, because traditionally many of those ~10x zoom lenses were either lacking in terms of optical performance (e.g. Sony FE 24-240mm 3.5-5.6 OSS) and/or I personally didn’t find the focal length range particularly useful, often starting at 28mm (e.g. Tamron 28-200mm 2.8-5.6 Di III RXD). Furthermore, if you want to review such lenses properly, it takes a lot of time and effort, equal to reviewing several prime lenses.
With its unique focal length range this Sigma 20-200mm 3.5-6.3 DG Contemporary intrigued me though, but can the performance of such a bold design be any good? I ultimately decided to buy one and see for myself how it performs, so here we are.
By mid 2026 we have seen a lot of lenses from the Chinese manufacturers: some with class leading optical performance, some with unique specifications, some very affordable. There is one thing we haven’t seen yet though (at least not that I can recall): an autofocussing zoom lens. I would have first expected a lens like that from Viltrox, Laowa or 7Artisans, but it is Thypoch – so far specialized in all manual M-mount lenses – bringing a lens like this to the market: the Thypoch 24-50mm 2.8 Voyager. Did they succeed in designing a lens like this, or was it too ambitious? Let’s find out together in this review!
Kodak Ektachrome E200 is a daylight slide film whose production ceased a very long time ago. I got my hands on a roll (expired in 2009), so let’s see what we are missing out on these days. 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.
Today I’m looking at another vintage lens: the Super Multi Coated Takumar 28mm f/3.5, made by Asahi Optical Co. before the company became Pentax. Over the years, this lens has earned a legendary reputation among vintage wide-angle lenses, praised for its sharpness and coatings that were considered exceptional for their time. Naturally, I wanted to see if the hype was real. Does it still hold up today, or is it simply a relic carried by nostalgia? Let’s find out.
Since its release in 2019 I have been using the Sigma 35mm 1.2 Art DG DN as my main lens for any kind of reportage work. 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 this Viltrox AF 35mm 1.2 FE LAB. As the Nikon lens sells for 3 grand it is out of reach for most people. This Viltrox lens is way more attractively priced, so let’s find out if it is time to retire my Sigma 35mm 1.2 Art DG DN after 6 years of usage. Last Update May 2026: information on new “N” version added
