Hi!
Fred, is the Tamron 28-75/2.8 too short for you? Don does not like its
bokeh, though.
Yes. (Do you mean the Pentax FA 28-70/2.8? - it looks like a really nice
lens, but I really need something longer, to avoid changing lenses at a
casual family gathering frequently.) I think that 28-105 might just do it.
Thanks for the suggestion though, Kostas.
Let me add my few cents worth.
Sigma lenses I witnessed myself are a mixed bag. My 18/3.5 is fine lens
(Thanks J.C.O). The 28-135 I bought new was rather average. A friend of
mine has 70-200/3.8 (older but still AF) zoom that he seems to like, yet
I think it was merely adequate...
If you look for top notch quality, Sigma probably isn't the way to go.
If you look for medium quality and convenience Sigma can be an option,
but in this case there are few more third party lens manufacturers to
consider, such as Tamron.
Ultimately however if you can stick with original glass, it would be
better... And then obviously you'd get to blame Pentax once more if need
be ;-).
I have one suspicion about /2.8-4 series of Sigma lenses - they are very
cheap new and just dirt cheap used... It must be a sign of something,
something not good.
