Sigma 70-300mm F4-5.6 DL Macro A-mount lens review by jakubh70
|jakubh70#4235 date: Oct-14-2008|
flare control: 3
|ownership:||I used to own this lens|
|compared to:||Sigma 70-300 DG, APO DG, 135-400 RF|
Minolta 100-300 APO
Tamron 28-300 XR Di LD Asph.
|positive:||Good sharpness in 70-200 mm range, price to quality ratio, 1:2 telemacro, solid feel, faster than comparable Minolta lenses|
|negative:||Not very sharp at 300mm, not so fast AF and front lens rotates - like the rest of budget lenses in this category|
|comment:||1:2 macro switch works only at 300mm, not in 200-300mm range like in newer versions. |
Aperture has 8 blades, is not rounded and one can receive nice symmetrical rays on photos when shooting points of strong light - but the flare can be a problem then. AF will be usually too slow to catch birds in flight, this will also limit its usefulness for dynamic scenes.
The copy I owed was used by smoker before and the dirt was between trombone and first ring what caused problems when focusing. After cleaning it got better.
