1. Introduction

Telephoto fixed focal length lenses with an exit pupil of near 10 cm have always been expensive instruments aimed at professional photographers. It's enough to consult their price lists to know that you have to pay a lot for such models as the 2.8/300 or 4/400.

The 2/200 models belonged to this group but they've never gained a level of popularity of two models mentioned above. There are three reasons for that. Firstly, the 200 mm model is more difficult to manufacture. In its case, with the same entrance pupil, you have to focus rays of light of the closest front element system and it makes it difficult to correct such a system properly well. Secondly, producers got themselves and us, the customers, used to the fact that the price of the lens increases with its focal length. The market expects that, out of the trio of 2/200, 2.8/300, and 4/400 lenses the first will be the cheapest and the second the most expensive. In reality, out of these three instruments, the 2/200 is the most difficult to design and to guarantee you high image quality. Thirdly, many experienced photographers already have in their arsenal professional 70-200 mm f/2.8 models and the 2/200 is, from their point of view, unnecessary duplicating of focal lengths. They prefer to spend their money on something like 2.8/300.

Small wonder 2/200 parameters have never been exactly popular. In times of reflex cameras such lenses were offered by Canon and Nikon but in the era of mirrorless instruments we had to wait for them really long. Finally two new models were launched on the market practically at the same time.

First, in August 2025, Sigma presented their S 200 mm f/2 DG OS and a bit later, in October the same year, the LAOWA 200 mm f/2 AF FF was launched by the Chinese producer Venus Optics. In order to be precise we have to add that both these launches were overtaken by Fujifilm that already in 2018 presented the Fujinon XF 200 mm f/2 R LM OIS WR – still in this time you deal with a full frame system.

We look at such treats with greedy eyes and are very keen on checking how they fare in our testing procedures. The Sigma lens we decided to test as the first and we got one specimen of this lens courtesy of K-Consult company, the distributor of Sigma product for Polish market – thank you very much!
