Ed Rooney Posted August 13, 2013 Share Posted August 13, 2013 I'm posting this out of frustration and confusion. Yesterday I picked up the 12mm ultra-wide at Adorama (an 18mm view on my NEX cameras). I gave up on finding a more affordable Sony or Sigma lens. The Sony 16mm I own is just not sharp. I was going to try the newer $200 Sigma 19mm, but its view of 28.5mm is not really what I need since I already have the wonderfully sharp Sony Zeiss 24 f/1.8. (There is simply not enough difference between a view of 36mm and 28.5mm for me to own and carry both lenses.) So I bit the bullet to the tune of $1,250 plus tax and bought the 12mm Touit. It's pouring rain out today, so I can't go out and work with the new lens. And I can't do much meaningful testing here in my small, cramped flat. When I put the Touit lens on my NEX-7 and turned on the camera the lens immediately started hunting back and forth . . . continuously. Hmm. When I depressed the shutter release half-way and the green focus aids showed up and the lens stopped hunting. If I hold the shutter release in that halfway position for a time, it still does not hunt. I snapped a few pics of my computer screen and my keyboard and they look sharp. I'll look at them in CS5 later today. When I attached the lens to my NEX-6; the results were basically the same. Now these NEX cameras are not simple; the NEX-7 has 100 menu items . . . and I've been using the NEX-6 a lot more lately, so maybe (probably) I've forgotten some stuff. If I have to I can live with this hunting problem as long as I end up with sharp images. I read somewhere that a firmware update is due this month from Sony for NEX cameras. Perhaps some of you out there might see something in this situation that I'm missing. Any help would be most appreciated. Ed Link to comment Share on other sites More sharing options...
