There is no reason to upgrade every time technology changes. To do so is absurd, unless there is either significant advantage from which you will garner income or simply have a lot of discretionary income to burn on luxuries. If you have a camera and buy a very good lens well matched to it that produces the results you want, you can use that setup until it stops working entirely, bypassing generations of new equipment at no cost. If you want an ultrawide lens for the DSLR bodies, buy a DA series lens. They're the best, if not only, choices available that make sense. It's that simple. The DA12-24, DA14, DA16-45, DA*16-50, and DA21 Limited are all excellent wide lenses available now that work brilliantly on the DSLR bodies. Lenses 20mm and shorter that were made for 35mm SLRs in days gone by may or may not perform as well, and beyond that they're just as expensive as any of these choices. If and when some better body comes available and *if* it includes a larger format sensor that cannot work with the lens you have, evaluate then whether or not the improvements it offers warrant the expense of buying it and a new lens as needed.
