    Put in my order for some new glass today and I can't wait to get it. I see there have been some questions surrounding these lenses lately so I will answer what I have found as well as ask a question or two of my own.

    Sigma 24-70mm EX f/2.8 DG-DF
    [​IMG]

    Here is what I found before the purchase . . .

    Filter size is 82mm

    f/2.8 is constant

    The lens coatings are "optimized" for digital but it is possible to use on a film body. The lens WILL fit both digital and film.

    Many reviews state that this lens is actually sharper than it's much more expensive Canon 28-80mm f/2.8 L - Although some people have complained of softness wide open. These were generally replaced by Sigma under warranty and the issue was resolved.

    What I do not know is . . .

    Is the DG-DF also the macro version? I have seen them listed both ways (ie: DG-DF Macro or simply DG-DF) Now the reason for the confusion is that all the specs I can find list a magnification factor of 1:3.8 and seems to be consistant whether it is listed as the "Macro" version or simply the DG-DF. Also there are DG only versions available that usually list out for a little less money. I also understand that the "DF" stands for "Dual Focus" but don't know if that pertains to Macro capability or not.

    Second question, is there a Cokin square filter system that will work with 82mm and up? I currently have the smaller 67mm version and need a bigger one if there is one. Also would the cokin system be cheaper than screw in filters for say C-PL and ND filters? How about grad ND and star filters?

    While I don't know the answers to your questions, I wanted to congratulate you on the purchase and on the upcoming Father's Day!

    Thanks! You too? (Don't remember?) Anyway I think I may re-post some of this with a little less self centered title. I think it's driving some possible prospective answer-ees away :confused:
