I should explain this better.... I am looking for a good lens to photograph with in a crowded room. I only mentioned feet in passing, but a lens that would allow one to take a photo from a minimal distance without leave enough room for people to walk between you and the lens and also would be wide enough to give you the feel of a small room. I like to have my camera with me a lot, and I don't like to have to move away from a group just to take a photo with the 50 or 70. I really like the range of the 18-250 or the 16-45, but I was hoping there was something smaller to fit on my KX like the 70 or 50. Plus, I often like to leave my camera out so others can pick it up and shoot a picture or two, and often they are intimidated by a zoom lens on an slr.
The holes in my lens are sub 14mm and greater than 320mm. I have been thinking about a mirror lens, but really I am happy with either the DAL 55-300, Tak 200, M 75-150 or the CRAP 70-320.
I don't keep many lens, really I would love to be able to rent them, but I just view the postage paid before I resell the lens as the price of finding my 'fav' set of lenses.
I like the idea of the FF, but is there a firm date on that yet? Last thing I saw was a dark japans page with no English and a shape of a camera that may have been a FF or a med format, there was much debate on the post as to which it was.
I have a spotmatic with a 28, 55 and 200 which is great... just want to move that feeling to digital... (don't we all!)
My vote for the wider end is the DA 12-24/4. It is a constant aperture, which helps with lighting, although 2.8 would be better. The quality of the lens is at least as high as your 16-45. I do not find the overlap in focal length excessive. When I am using the one, I don't carry the other. As to 28/55/200 - you already have that on your DSLR. The 16-45 is the equivalent to 24-67 mm, and your other lenses fill out.
