Recently bought a Nikon 24-70mm f / 2.8G IF-ED AF-S. Took off at home, tested and passed back to the store. Heavy enough for a small range of focal lengths. No stabilizer, poor mechanics. Most chromatics and poor bokeh for the declared class lenses.
Film format; Beautiful rich color; Large focal range with acceptable quality; Good sharpness, small curvature of the image field for zoom; Diaphragm 9 rounded petals, good bokeh for zoom; Easy, fast and accurate focusing; Excellent mechanical quality
Traditional disadvantages to such a range zoom: - A slight drop on the field at the corners extreme focal lengths at the aperture (disappears when you close diaframy per division); - Noticeable distortion at wide angle
