exposure issues with D300 & sigma 24-70

[dave-nikon1958]

Hi all. Anybody had or know about inaccurate exposure readings with D300 & Sigma 24-70mm 2.8 ex aspherical lens. Mine seems to be underexposing by approx 1-1.5 stops.:bang::bang:
Cheers Dave.

I noticed that mine does on both my d80 and d200, thought I was going round the twist will keep an eye on this thread and sea what comes out of it.

Have a word with Sigma, they re-chipped one for me (foc), apparently due to compatability issues with D40, that didn't work with my D300 - does now!

Hi All. Been in touch with Sigma they say it does look like it needs rechiping, the cost is about £34 so not to bad, keeping fingers crossed.They say it's a 2-3week turn around.

Cheers Dave.
