Minolta 28-75 f2.8 D what are your thoughts?buy?

hey everyone.i am seriously considering buying this lense but its $500!! Its a brand new lense from minolta.But it was specificaly designed for the 7D, i was wondering would it's full potential be dwarfed if i used it on my regular maxxum 7?

any help would be apreciated on this decision.

this lens is good for both 35mm and digital, its title 28 75 mm is for 35mm film camera.the equivalant focal length for digital, 7d, is 42-112.5mm.
buy it if you want 28-75mm f2.8 on maxxum 7.
Mark.

This particular lens is actually being made by Tamron. It's a Tamron design, with some Minolta-engineered modifications (different coatings, and different focus gearing) to optimize it for the 7D's digital sensor. It also works fine with film, from what I hear.

Now, mainly shooting film, you could also get Tamron's regular version, which is about $150 cheaper - and have the same optics, with the coatings optimized for Film use. This wouldn't have the Minolta's 'D' encoder, though - so the final deciding factor may well be how much you actually use that feature.
