Mark,
I have thought of that, but I have a Sigma 70 -300 mm f 4-5.6 Power zoom
that I like very much. It has been a good lens that I have had for a
while. For zooms I use, the others are: : Pentax 20-35 mm f4, and my
old Tamron 35-135mm f 3.5-4.5, which is used when I feel I need to be
in that range, but it is totally manual and somewhat ungainly. It is
only slightly smaller and heavier that the Sigma.
I had not thought of the 28-104 mm lens because I use the Sigma so much,
but it is one way to get over the hump with relatively modern lenses.
If I did that i probably would then go looking for something like a fast
40 mm lens. A lens in that range has been in the back og my mind anyway.
So many choices, ah well.

You might want to consider a 28-105 f4 - 5.6 power zoom. I did some
informal testing / playing around while bored this weekend and was
really impressed with how sharp my copy of this lens is on the K-3. At
50mm f8 it was pretty close to the A 50 f1.4, which actually surprised
me. I use it mostly on film bodies and will say that it does have some
softness in the corners and edges on film exposures but is still quite
good. Drawbacks are that it is heavy (due to the useless power zoom
feature), slow (f4 - 5.6), variable aperture and has a rotating front
element. None of those are really show stoppers for me. I sometime use
the power zoom on the Mz-S and Pz-1p.
I also tested my copy of the FA 28-70 f4. Clearly not on par with the
28-105 but pretty good. Back in the film days I actually preferred it
to the 28-105 - maybe my copy is deteriorating. I would not recommend
going with one of these, though.
Good luck!

I have been using my Pentax 20-35 MM and a Sigma 70-300 MM and have
been mostly happy with the results from these two lenses on my ist
DS. But the man in the middle is an elder lens (Tamron 35-135 mm
Manual Zoom and focus) and I think it is time to replace it. It seems
as though both Tamron and Sigma have mid range zooms that have
received nice reports. I have been pleased with my long Sigma and
may be swayed in that direction. But before I go do something, I am
curious about what the group would go to and how they think a future
camera upgrade might affect the choices?
Cheers John G.
