Yes. You could injure your back carrying the DFA 15-30 around. And you'll likely need a larger camera bag.

Also, you can't use screw-on filters.

I know DFA 15-30 is full frame (on a K-1 or K-1 II), so would that equate to about a 22-45 field of view (on APS-C bodies)?
Even so the actual focal lenghth doesn't change right?

With the additions added for clarity, yes- you've got it right.

These are a very reasonable alternatives, and also a great WA zoom lens, or an amazingly small WA prime lens.
