Below are just my 2cents.


After reading through the conversation and advices from others, Well, I wouldn't say that Silverfire is at fault anymore. A fact that you own the lens for a month only then you realize the missing screws is weird.

I mean, normally when we get something new, we will instantly play around with it right? So the moment you got the lens, you should have notice there is a problem with the lens already..not after 1 month..unless your answer is that you got your lens and you keep it for 1 month then you play with it then... no comment.
