hey guys,
i have a few questions regarding this lens (which i so happened to purchase today).
First off, i am in love with its black matt/sparkle finish... its so beautiful!
but i come here to ask for some advice, ive read around on some other blogs/forums that while it is a constant f/2.8 (DOF-wise) light wise its not... dont know if that makes sense.
ok... heres an example...
Im in manual mode. when im zoomed to infinity i can get aperture of 2.8, but the closer i get to my subject the aperture increases. Thus making the picture darker.
when im focused in to its closest focusing range, the minimum aperture i can get is f/5.6.
i read that its normal on some forums, and that the depth of field does not change, it just limits the amount of light that it lets in.
then the other forums went on to explain this or something ( i got sorta lost). But what they finally went on tos ay is that it occurs on msot macro lenses, and tis jsut that nikon shows teh actual effective aperture while other camera brands show what is selected...
the more i look into it, the more confused i get...
can anyone help me understand this?
thanks in advance,
tomorrow i get my flash, so its time for some macro work before i get drafted
