The first crop from the NEX-7 is sharper and shows more detail. The variation in sharpness from the edge to the centre of the frame obviously has more to do with the lens than the sensor but overall the results from the OM-D E-M5 with the 12-50mm kit lens are very good.Ĭompared with the crops from the NEX-7 there’s variation from crop to crop, but overall no decisive factor that would swing it in favour of one or the other. The last crop from close to the centre of the frame is the best one with clearly defined fine detail and nice crisp edges. The OM-D E-M5 has no in-camera lens correction options but this could easily be fixed in the RAW file. Moving onto the third crop from the edge of the frame, the detail here is marginally softer and there’s also a little bit of red fringing on the window frame and drainpipe, indicating a degree of chromatic aberration on the 12-50mm kit lens. The lighthouse is reasonably distinct and the edges of the window frames are clean. The first thing to note is that the OM-D EM-5’s 16 Megapixel sensor produces crops that show a larger area with smaller details than those from the 24 Megapixel NEX-7 and D3200, but what difference can you expect in practice? After a bit of a lacklustre start with the first crop the OM-D E-M5 does a much better job with the detail in the lighthouse and the foreground windows and rooftops in the second crop. The NEX-7 was adjusted by +0.3 EV to produce the same exposure. The OM-D E-M5 metered an exposure of 1/1250 at f5.6. The camera was set to f5.6 in Aperture priority and the sensitivity was set to 200 ISO. The image above was taken with the Olympus OM-D E-M5 with the M.Zuiko 12-50mm f3.5-6.3 lens. The ISO was manually set to their respective base sensitivities: 200 ISO on the E-M5 and 100 ISO on the NEX-7 and D3200. Each camera was fitted with its respective kit zoom and adjusted to deliver the same vertical field of view.Īll three cameras were set to f5.6 in Aperture priority mode, stabilisation was disabled for this tripod-mounted test and tone enhancement features were left on the default settings To compare real-life quality, I shot this scene with the Olympus OM-D E-M5, the Sony NEX-7 and the Nikon D3200 within a few moments of each other using their best quality JPEG settings.
