Many of us have had the opposite experience. The only lenses that have worked flawlessly for me are sigma lenses. The only lenses I've had issues with are canons and tamrons. | Bodies - 5D Mark II, T2i | Lenses - Helios 44-2, Sigma 35mm 1.4, Sigma 85 1.4, Sigma 70-200 2.8 OS, Tamron SP AF 1.4x TC | Lights - 430ex ii x2, Random 3rd party strobes
