I had been asking for advice over at the "other forum" about the merits of the DA12-24. I already have the DA14 but desired to have a more versatile lens, especially when it comes to tour time. Matched with the DA*16-50 and the DA*50-135, this would make for a great travel kit with a nice overlap at the wide end between 16 and 24mm.
After a short walk yesterday afternoon and a few photos, all I can say is that this is one heck of a lens. Much better image wise than I anticipated and a very convenient zoom range. The colour rendition is excellent, it is super sharp and the bokeh can be pleasing in most situations.
The only draw back? My Cokin P series wide angle adaptor vignets ever so slightly at the 12mm end.
Having said that, the ND grads mated to this zoom make some real good photos.
I will add that the following photos were taken in some very trying high contrast conditions of afternoon sun and mainly into the lens and as such you may see a little flare. This may have had to do with the ND grads rather than the lens itself.
Here are a few samples:
