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 40mm 1.4 Art

The Sigma 40mm 1.4 Art DG is one of the heaviest non-super-tele prime lenses and on first sight it also looks more like a serious tele lens than a medium wideangle. But is it also as good optically as it is heavy? Let us have a closer look!

Sigma now offers the DSLR designs 35mm 1.4 Art and 40mm 1.4 Art and the newly designed 35mm 1.2 Art for Sony E-mount cameras. Let us find out what the differences between those 3 are and if there is a reason to get one of the bigger, heavier and more expensive lenses.

How good a camera you need? – A closer look at the Huawei Mate 20 Pro

Introduction

Very often we get asked questions like: should I get lens X or lens Y? Out of lens X, Y and Z: which is the best performer? Which 35/50/85mm lens should I buy? Do I need a camera with 42mp? Is the Zeiss Batis 18mm 2.8 or the Zeiss Loxia 21mm 2.8 sharper?
For several reasons we usually cannot answer these questions: rarely we know what you want to use the lens or camera for and often the difference between a good and a bad sample of the same lens is bigger than that between two different lenses.
So, to give you a different perspective, in this article we will look at the Huawei Mate 20 Pro, a smartphone with above-average camera capabilities and see what results can be obtained from this pocketable 200g device.

You have been asking for reviews of Sigma Art lenses for quite some time now, so I am glad that I can finally present you one of the Sigma 35mm 1.4 Art. Let us find out if this is the better choice compared to the Sony FE 35mm 1.4 ZA.

Zenitar 50mm 0.95 E on Sony A7rII

Zenith is mostly famous for still producing decade old designs like the Helios 2/58 and some Kickstarter lenses like the Petzval. But this Zenitar 50mm 0.95 E is a completely new design with staggering specs. But how does it stack up to the Zhong Yi Mitakon 50mm 0.95?
This was supposed to be a full scale review, but unfortunately this lens is so inherently flawed that I decided writing one would be a waste of time, read on to find out why.
