Sigma 30mm f/2.8 EX DN Review at Photographyblog (Click here): “The Sigma 30mm f/2.8 EX DN therefore comes highly recommended as an unobtrusive, lightweight and above all affordable performer.”

Olympus M.ZUIKO ED 75-300mm f/4.8-6.7 Lens Review at ePhotozine (Click here): “Optically, this lens performs reasonably well, producing good sharpness across the frame, at least. Compared to other lenses compatible with the Micro Four Thirds system, it falls short of the performance of the best lenses available.”

#23/#32 are F0.95, #31/#40 are F16, in between are full click stops. All Lightroom processed. -2 is LR “all edges” defringe. -3 is defringe plus “Direct Positive” preset. No other adjustments applied.
Bottom line – in modest backlight, significant edge fringing at F2 and wider. LR defringe only modestly useful. Strong backlighting would increase fringing. Avoid strong backlights when shooting wide open. GH2 used for this test.” (P:S.: The lens is in Stock at Foto Hans Keuzekamp).
