I'm looking for a new lens for my Minolta 330si. I go to a lot of auto races, so I want something that will focus pretty fast. I also like shooting wildlife, so quiet is good too. Obviously lens quality is important as well. The two lenses I was looking at are the
Konica Minolta - 75-300 MZ D Autofocus Zoom Lens
Lens: 75-300mm f/4.5-5.6 (D) (S)
Lens Construction:13 Elements in 10 Groups
Angle Of View: 32 - 8-degrees @ 10'
Minimum Focus: 4.9 feet
Max. Magnification: 1/4
Filter size: 55mm
Dimensions: (diameter x length) 2-13/16 x 4-13/16 inches
Weight: 16.25 ounces
and
Quantaray - Tech-10 70-300mm f/4.0-5.6 High Speed Auto Focus Zoom
Focal Length: 70-300mm
Focus Type: Auto
Aperture Type: Automatic / Variable
Aperture Range: F4 - 22 (70mm) F5.6 - 32 (300mm)
Optical Construction: 14 Elements in 10 Groups
Minimum Focus: 58.5" (37" in Macro at 300mm)
Macro: Yes (1:2)
Filter Size: 62mm
Size/Weight: 4.7"x2.9" / 20.6oz
Going on the theory that a non-minolta lens should be chaper for the same product, and these are about the same price, is the Quantaray better? I realize tht it's heavier but that's not too improtant to me. The slightly better macro won't be too useful for my applications. Any thoughts?
