IT is always possible to take photographs with secondary reflections and veiling glare. NO lens I know of is immune to forced glaring effects. More important is the performance in more 'natural' circumstances. When taking pictures with the object against a strong light source (sun or whatever) the V-E holds clear edges, dark areas and very fine detail in the non-lit areas. The highlights are very clean, with subtle shades of white light illumimance. the shadow colors are clean and well saturated. Microcontrast is very high and no loss of overall contrast. When strong veiling glare illuminates parts of the picture you will notice a haze of lightness, but within these areas and just outside the veiled areas, fine subject detail is preserved with good contrast, but the colors are of course more pastel-like. The V-E can be used without any reservation in strong backlit situations are in oblique lighting when the sources are just outside the lens elements. When forced you will notice an occasional strongly colored secondary reflection in the inage, but you need to force the lens into a quite extreme position. Efficient coating on the almost twenty free lens surfaces is evident. Optically this lens brings the vario performance a few steps higher. The 70 position is the best and has Apo qualities. The smooth controls (focal length and distance rings) show a exquisite engineering quality. The 4/35-70 is for GP use and this one is best for demanding picture taking situations when you need image quality above the one you can get with the equivalent fixed focal length lenses. The outstanding quality in the field is most noticeable and now you can use the whole image area from center to corner with authoritative imagery.
