My name is Bastian and for many years I have been mostly shooting Nikon DSLRs. As of today I have made my transition from Nikon to Sony and I am mainly using small but capable manual lenses. My passion is landscape photography but I also like to delve into other subjects from time to time.

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!

The Sigma 35mm 1.2 Art DG DN is the first true full frame mirrorless lens designed by Sigma and also the first full frame 35mm f/1.2 AF lens. Is this finally the high quality 35mm lens we have been waiting for?

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.
