In my opinion, the magnification is 1:4 but the lens do produce soft images especially around the edges. Not really a good lens for macro-works but for the price it offers, it's quite ok. I would advice you consider the 70-300 counterpart which at least offer 1:2 magnification (see earlier posts for more info)
