@Brightcolours : Agreed, there are certainly happy Sigma campers out there, same goes for Tamron and Tokina; I wasn't so lucky or satisfied when I tried out a Tammy 28-75 2.8 and a Tokina 12-24 in the time I had a D200.. maybe a just got lemons, but since then I sticked with Nikkors and only had one sample in my hands that apparently was sub-standart (a 70-300 VR).. As to my 24-70 sample I've used it both in daylight and studio environment and had no issues with light-streaks, so I guess it doesn't require any fixing.. <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='' />



Indeed there is a premium to be paid for high end Nikon (or Canon) glass, when you look at it as a longer term investment, it hurts less <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='' /> and well, it's always a personal choice as to whether an additional performance upgrade (in IQ / AF / sturdiness) is worth the outlay or not. Too bad it's so far from linear <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='' />
