I've got the Sigma 17-70 f2.8-F4.5 and the Pentax 50-200 f4-f5.6 for my
K100D after much research. My priorites were image quality and price but
f2.8 and reasonable macro ability was an attraction also with the Sigma.
With the plentiful white/grey skies here I also had to get lenses with low
purple fringing, the Pentax 18-55 kit lens doesn't do too well in this
respect although it's good as far as 18-55 kit lenses go. This Sigma is
better quality for me than other Sigmas like the 18-125 and 18-50, but it's
best to look at loads of images and make your own mind up.

Personally I prefer some overlap between the lenses. If the two lenses
both end at 50mm (as above) you will inevidably find you somehow need to
set the lens to even the slightest gap between the two lenses. Smile But if
the long lens goes down to 28 or 35mm while the wide lens goes up to 50mm
or so, many tricky problems disappear.

This is a possibility but you may want to think of how you will use the
camera. First in digital, the difference between 18 and 28 is very large.
so if you like to take landscape shots, 28mm is very restrictive. Also I
have found that in general the wider the range of focal lengths the
heavier the lens. So a 100-300mm lens may be lighter (and frequently
faster) than a 28-300mm lens. The extra lengths require more elements and
more mechanical movements which add weight. Of course this is a
generalization and you may find specific lenses otherwise.

My suggestion (purely my personal preferences) would be an 18-50mm (or
even a 12-50mm or so) and a 28-300mm or 35-300mm. This way you have
plenty of overlap. Or an even better choice (IMHO) would be a 12-50,
35-150, 100-300mm combination. Of course in such a case you now have to
balance how to carry all these lenses vs having to have a large heavy
lens hanging from your neck when you only need a wide angle view.

So much of lens choices are very individual and depend on intended use,
personal preference and availability of apropriate lenses at a price you
can afford. Smile

Agree completely. The 28mm end is not very wide by todays standards and many
shooters like 18mm lenses, in fact many are3 choosing somethig like the
18-200mm that are becoming available but I think you will find the smaller
zoom ratio lenses will give a little better quality.

I would recommend the Sigma 18-125mm and for the times you need longer I
would suggest the 70-300mm DG APO. These two lenses suit the K100D nicely,
you will find for most shooting you will not need the bigger lens much.

I suggest you also look at the 360FGZ Pentax flash or even better go for a
Sigma 500 DG Super.
