\/--\/-- >Hello pavel! Most opinions I have read about the two lenses - CZ 4/18 and CZ 2,8/21mm - say the opposite: the 21 mm is better. And that is also my own opinion. The problem of FMs rating is, that all lenses, which are better than the bottom of a bottle are crowding between 8.8 and 10. I have not understood, how they rate. I do not think, price goes into it - that would be stupid! A consumer wants the jutgment on the real properties of a product. He knows the price himself - so he can then create his own opinion about performance/price-ratio! I will tell you as soon as I have found out.... In their verbal comments you can see, that they never want to hurt anybody.... I found their rating is a certain guideline - but it is not much more reliable than photodo... Sometimes I find it confirmed, sometimes obviously not. I really cry after the old times of "Modern Photography". American testers seem to look much more realistic onto the products. Good luck with all the confusion! Herbert
