You should congratulate the Sigma Corporation and their optics specialists for two reasons. Firstly for their courage – they attempted to produce an instrument no other company had tried to construct before. Such a situation a lot can be forgiven so their product didn’t have to be outstanding. Still it is obvious Sigma wasn’t contended with half measures; not only they manufactured a unique instrument but also made it optically excellent in many categories.

What’s important, I am sure there would be those willing to pay 4,000 – 5,000 PLN for such a lens and Sigma, taking into account the lack of competitors, could demand easily such an amount of money; however the company didn’t decide to follow that strategy and suggested a price which is within the reach of many amateur photographers. That’s why I don’t doubt that, like the Sigma 35 mm f/1.4 EX HSM, the 18-35 mm f/1.8 model won’t stay long on the shop shelves.
Despite the slip-up during the work against bright light, taking into account all the achievements of the Sigma and its price we don’t doubt it deserves the badge below. Congratulations!
