Sigma 875205
Why we recommend this ▼
Doubling the reach of compatible Minolta-mount lenses, this dedicated APO teleconverter maintains auto focus and AE functionality without complex exposure calculations. Its apochromatic design suppresses chromatic aberration, a key differentiator for a converter at this level, though it lacks weather sealing and stabilization. This converter is best for portrait and street photographers needing extra focal length on a budget, provided their lens has a sufficiently bright open-aperture F-value.
