This one

Is only compatible with the APS sized DSLR's from Sony and KM.
It is not compatible with a film camera.

I'm saving up for a a-700 ! It's just that I have good Minolta
lenses that I want to use on both film and dslr cameras .

But the super wide angle of the 11-188 mm has me interested .
Apparently it's equivalent to a 16.8 mm wide angle lens on a 35mm .

The "Sony" 11-18mm looks nearly identical to the Tamron 11-18mm lens -
most likely the Sony version is made by Tamron. Of the third-party crop
sensor ultra-wide rectilinear zooms, IMO it is last pick of the bunch,
with Tokina and Sigma offering better (sharper/lower CA/wider and or
faster/better built) options (Tokina 12-24 f4 and Sigma 10-20mm f4-5.6)
at slightly lower price. (Canon and Nikon make good 10-22 and 12-24 crop
sensor ultra-wide zooms at nearly double the price).

These lenses will vignette severely on 35mm, as the image circle will
not cover the sensor/film plane Sigma make a 12-24mm "full-frame"
format lens which AFAIK can be obtained as a non-HSM version with
minolta mount, and should work on both Sony A100/700 and film cameras.
But the lens will be a compromise on the crop sensor digital cameras -
the large protruding front element does not allow use of front filters
for protection and makes the lens more prone to flare than the
crop-sensor ultra-wide zooms (flare is a a problem with ultra-wide
lenses as the sun or bright light source is often either in the frame,
or on the periphery of the frame).

yep.

the canon/nikon lenses won't fit his sony camera.

actually, the tokina and tamron will cover the full frame in part of
the zoom range. however, because they are designed for the smaller
sensor, corner performance isn't necessarily going to be ideal.

This is AFAIK the widest full frame rectilinear lens made by anyone. I
have one, it's good for architecture and evenly sharp corner to corner
(cropped frame at least) but not particularly sharp or contrasty anywhere.

Yes, lots of green & purple blobs I hold my hand out to shade it.

I use a Sigma 10-20. Flare is not so much a problem, but ghosting can
be - usually the ghosted light source is small enough so that it can be
cloned out in PP. I use a filter (Hoya MC), and couldn't see any
difference when not using the filter in test shots - except that when
focusing close and/or at small aperture, specs of dust on the filter are
visible (not confused with dust on sensor).
