<p>http://www.photo.net/photo/17934297<br> http://www.photo.net/photo/17932514<br> were taken with either 25/2.8 or 50/1.4 lens (I forgot which one I used for particular shots, that's one disadvantage of fully manual). The originals are 4000 x 6000 of course.<br> The comparison was meant with the Sony Zoom FE 3,5-5,6/28-80 that was delivered as a kit with the camera, not the Zeiss ones. The Sony Zoom has heavy distortion at the edges in wide angle.</p>

<p>I own the A7 plus several Contax lenses (28/2.8, 35/2.8, 50/1.4, 85/1.4, 135/2.8...). The wide ones cause some vignetting in the corners if fully open, they need to be stopped down by one or two steps. At full speed you loose about two steps in the corner. So the very fast lenses do not make too much sense.<br> You can correct this with post processing, but forget the general purpose aperture correcting tools frequently offered - they never fit the vignette. <br> I also get reflections if a bright object in the picture, e.g the sun in the center causes a 2nd sun nearby.<br> But besides these disadvantages in special situations, the lenses do a great job on the camera. They totally outperform the original Sony lens.</p> <p> </p><div></div>
