Guide to Ultra Wideangle lenses for the Sony a7 series v1.2

super wide angle ultra uwa swa

We summarize our experience with all the native E-mount and a few (manual) legacy lenses in the 10-20mm bracket to give you a compact and independent resource for choosing the right super- to ultra-wide-angle lens for your Sony a7 cameras. In this summary we also included some adapted lenses we think are worth mentioning.

We also have a guide to 21-35mm lenses.

We have no association with any lens manufacturer apart from occasionally loaning a lens for a review. Before any short introduction we tell you how long we have used a lens and if we have borrowed it from a manufacturer. But in most cases we have bought the lenses new from retail stores or on on the used market. If you want to support our independent reviews please consider using one of the affiliate links. It doesn’t cost you anything and helps us a lot.

If we have left any question unanswered please leave a comment and we will do our best to answer it.

Laowa 4.5-5.6/10-18 FE C-Dreamer

Status: Sample loaned by the manufacturer reviewed by Bastian who is still undecided whether he prefers this over the 10mm Voigtlander.

  • super compact (similar in size to Zeiss Loxia 21mm 2.8) and even slightly wider than the 10mm Voigtlander
  • contrast and resolution are never great, needs stopping down to f/8 to f/11 for okay corner sharpness
  • flare resistance worse than the wide Voigtlander primes, very nice sunstars thanks to 5 straight aperture blades
  • complex distortion and high vignetting, hard to correct because of missing electronic contacs
  • Widest rectilinear (zoom) lens available in a very compact package, but takes some work in post for good results

Guide to Adapters for Manual Lenses on the Sony a7 series

There are many good reasons to adapt manual lenses to the Sony A7 series cameras. To do so you need an adapter and this article will help you to choose the right one.

We are three guys from Germany who have adapted manual lenses for many years now. By using several dozen adapters over the years we have learned the hard way, that not all adapters are created equal. We hope that the money we spent on bad adapters will help you to avoid annoying miss-buys we experienced.

In the following two parts we tell you why you need an adapter in the first place, and which issues can arise with adapters. If all you need is the right adapter for your lens you can simply jump to Adapter Manufacturers].
