Hi Darren,
I have the Sigma 70-300 /4-5.6 APO DG, I like its sharpness and I made
some very nice macro's with it (it has a macro switch for 200-300mm) It
is bulky but supprisingly light weight.
Recently I did a comparitive test with some lenses a had that covered 200mm.
I took pictures at following conditions:
only at 200mm, distance 3m, tripod, mirror up (2 sec pre time), 400ISO, K5
My opinion pixel peeping the pictures:
Pentax and Tamron 28-200 @ F5.6 and F8 Okay (T and P very simular)
Pentax A 70-210 @ 5.6 sharp maybe the best of all @5.6, @F8 very sharp
DA 50-200 @f5.6 not good @ F8 improved a lot but no A70-210
Sigma 18-200 F8 quite good not worse than 50-200
Sigma 70-300 @ 5.6 and F8 nicely sharp
SMC-M 80-200 not so nice
Sigma 28-200 F8 quite good, F5.6 bad
Sigma 135-400 @5.6 very good, maybe the best, @ F8 super
Pentax F80-200 not bad
I will never sell my Sigma 70-300 at usual prices

Went to the local Henrys today to get some Epson 2400 inks and the
Pentax remote F. I asked a few questions about the 55-300 and he
steered me to a lens on sale till Aug 31st. The Sigma 70-300. Its on
sale for $199 down from $299. I was surprised at the low price, but we
tooks a few in store photos with it and i'm impressed with the IQ.
Anyone using this one, comments.
He said he had one for his Nikon, but i find salesmen always have what
they are trying to sell. He did show me some photos on his iPhone that
he claimed were taken with it, and they looked good on the small
screen.
