The Sony DT 11-18mm is actualy the widest angle Sony zoom for Alpha DSLRs (see Sony Alpha A100). In fact, is compatible with both cropped-frame Alpha DSLRs and the earlier Konica Minolta Dynax / Maxxum 5D and 7D bodies (DT 11-18mm, like many Sony lenses, is actually a rebranded and slightly modified version of an existing Konica Minolta model).
The DT 11-18mm is offering an equivalent range of 16.5-27mm, a range which is ideal for capturing big landscape views and large buildings both inside and out. With only 1.63x optical zoom ratio, if you zoom in you have a more typical 27mm wide angle coverage. The maximum aperture of f4.5-5.6 is a little slower than some ultra-zoom rivals at the wide end, such as Canons EF-S 10-22mm f3.5-5.6, but matches most when zoomed-in, and, it shares many similarities with the existing Tamron 11-18mm lens.
If you want to use it with filters, note that you need a 77mm diameter filter. The physical dimensions of the lens is 83mm and 81mm in length when zoomed-out, while it weighs 360g.
Lens System: 11 elements in nine groups and features a seven-blade aperture diaphragm.
