My name is Bastian and I am your expert here when it comes to ultra wide angle lenses, super fast portrait lenses (ranging from a 50mm f/0.95 to a 200mm f/1.8) and I also have reviewed way too many 35mm lenses. Don't ask me anything about macro or wildlife shooting though.

Review: Sigma 50mm 1.4 EX – Still worth getting in 2020?

Introduction

Back in 2008 the Sigma 50mm 1.4 EX was the biggest and most expensive 50mm f/1.4 lens with AF for DSLRs. Now, 12 years later, it looks reasonably sized compared to its modern competitors and can be found used for bargain prices.
But is it a lens still worth considering in 2020? Let us find out in this review!

Introduction

Landscape astrophotography is something I have been doing for several years. Luckily over the past few years many lenses have been released that make this task easier than ever. So today we are going to have a look at all the available lenses for your Sony so you can choose the one that works best for your needs.

What is landscape astrophotography?

Sony A7s | Nikon AF-S 20mm 1.8G | f/1.8 | 3 shot panorama |

In landscape astrophotography you will usually try to have a combination of the starry sky (with Milky Way or Northern Lights) as well as some foreground (e.g. landscape) in your frame so we are mostly looking at ultra wide to normal lenses (for stitching) here.

Review: Laowa 15mm 4.5 Zero-D Shift

For 11 years the Canon TS-E 17mm 4.0L was the widest shift lens available and now it is not Nikon but Laowa who challenges them with their 15mm 4.5 Shift. May this be the new king for wide angle architectural photography?

Review: TTArtisan 50mm 1.4

Introduction

TTArtisan 50mm 1.4 on Sony A7rII

To my surprise – shortly after the 50mm 0.95 – TTArtisan also released a more reasonable 50mm 1.4 lens. The optical design looks very interesting on paper: a longer focal length double gauss with a “speedbooster-like” rear group. This is similar to Cosina’s latest designs for the fast Voigtlander lenses, is this a good sign? Let us find out in this review!
This lens will be reviewed on the 42mp Sony A7rII and the 24mp Leica M10.

The 7Artisans 35mm 1.4 IF came as a bit of a surprise as it features an internal focus design. Something, which is still rarely seen among M-mount lenses and a novelty for 7Artisans. But does this also translate to superior optical qualities? Let us find out in this review!
This lens will be reviewed on the 42mp Sony A7rII and the 24mp Leica M10.
