<p>Zeiss? The Sony-Zeiss lenses certainly don't measure up to Zeiss lenses. Nikon can produce competitive lenses without Zeiss.</p>

<p>Yes they do and Nikon hasn't. I have several of each, and Sony G, Sony/Zeiss and Zeiss are all first rate. The only Nikon lens that comes close in sharpness is the 55/2.8 AIS Micro-Nikkor, but the bokeh is not all that good. Nikon does okay in the 400 - 600 primes, but their shorter lenses and zooms are relics of another age."</p>
<p>Edward, Edward, that flies in the face of Ming Thein's experience with these lenses. Here's an excerpt from his remarks:</p>
<p><strong>Sony Zeiss FE ZA cobranded (<a href="http://www.bhphotovideo.com/c/buy/sony_zeiss/Ntt/sony%2Bzeiss/N/0/kw/search/BI/19242/KBID/11109/DFF/d10-v1-t12" target="_blank">B&H</a> <a href="http://amzn.to/1kihypu" target="_blank">Amazon</a>)</strong><br /><em>2.8/35, 1.4/35, 1.8/55, 4/16-35, 4/24-70, many others for DX and A mount via adaptors. Pick of the bunch: 1.8/55</em><br />These are native mount, offer full functionality and the best value for money. They are made by Sony and not QC’d by Zeiss as per the other lenses; this means there is some significant sample variation possible. The 1.8/55 <em>can </em> be very impressive if you get a good copy; I’ve had to test six to find one though. Other lenses have significant field curvature/focus shift (the 2.8/35 for example) or are average (4/16-35). The 4/24-70 is a real mediocre disappointment and it’s a wonder that Zeiss ever agreed to have their name on this thing at all. I am not considering the SLR A mount lenses here because they are very expensive, clunky in operation via the various adaptors, and will really only work on Sony cameras – IMHO, not worth the investment given the recent confusion (by their own local principals, no less) over whether Sony was discontinuing the Alpha mount. Needless to say, it does not really inspire much confidence. But that might mean some used market bargains to be had…"<br>

He had to try 6 samples to get a good one? Clearly that is NOT up to Zeiss standards. If you want to see the entire article try this link.<br>

<p>I think you're are being blinded by your Sony loyalty. </p>
