Very well known sources confirmed that Sony will launch a premium quality standard zoom lens in 2013. I don’t have the exact specs and release date yet but I have been told it’s a ZEISS! I have been told it will be similar to the current Zeiss 16-80mm f/3.5-4.5 A-mount lens
http://www.sonyalpharumors.com/sr5-ther ... eiss-zoom/ Of nearly 3000 voting 45% would consider buying one. A $999 price is suggested. That would probably be £900 here in UK.
I have the A-mount CZ16-80 and love the output it can produce on my A580. Not sure I would invest that amount of money as I cannot see the lens being smaller that E18-55mm kit lens. I am looking for weight loss rather than gain as well and wil probably stay with my 16-50mm pancake. If I felt like putting the CZ in front of my NEX I would use my LA-EA2 in between. The old NEX lens map contained a G type E standard Zoom. Perhaps the G has been transformed into CZ and thus we are not actually witnessing an addition to the old lens map.
