I was just perusing the Photodo & Photozone
tele-zoom (70/80 - 300 range) reviews and
found the following: (higher, generally better)
Photodo-
Pentax FA 80-320/4.5-5.6 = 2.5
Sigma AF 70-300/4-5.6 DL MS = 2.9
Sigma AF 70-300/4-5.6 AP M = 2.4
Tamron AF 70-300/4-5.6 LD =2.4
Photozone-
Pentax FA 80-320/4.5-5.6 =3.01
Sigma AF 70-300/4-5.6 DL MS = 2.17
Sigma AF 70-300/4-5.6 APO M = 2.60
No Tamron listed
I know all these different reviews are hard to
compare, but its really confusing to see one case
where the Sigma DL lens outperforms the Sigma APO
lens, and another just the opposite and also
where the Pentax 80-320 is somewhere in between.
In general, what have folks' experiences been
w/ any of these lenses? The consistent best
performer in tests has been the Tokina ATX 100-300
but that's quite expensive and quite heavy.
thanks!
