thebeephaha Offline Image Upload: Off p.1 #1 · Sigma 70-200 Troubles..... Wellllllll... My recently purchased Sigma 70-200 2.8 (non DG) is having some af problems, mainly the chip because it still works fine on my schools old D1 but literally will freak out on my D70 every now and then. I emailed Sigma and they said they will rechip the lens for free however... So I guess thats a big plus! Edited on Nov 29, 2005 at 05:55 PM Nov 28, 2005 at 06:17 PM

chemprof Offline Image Upload: On p.1 #2 · Sigma 70-200 Troubles..... Sigma seems to be really good about that... I've heard that they will do that universally, and at no cost. I've had GREAT luck with my four Sigma EX series lenses. Great quality, great images. No regrets. Gerald Edited on Nov 29, 2005 at 05:55 PM Nov 28, 2005 at 08:03 PM

thebeephaha Offline Image Upload: Off p.1 #3 · Sigma 70-200 Troubles..... Yea I love mine alot, and once it gets re-chipped I should love it even more! Alot of guys complain how Sigma sucks and stuff but in all reality... They make some really nice lenses and seem to stand by them. Especially in my case considering its a used lens without a warrenty. Edited on Nov 29, 2005 at 05:55 PM Nov 28, 2005 at 10:46 PM

caryb Offline Image Upload: Off p.1 #4 · Sigma 70-200 Troubles..... Interesting. I've used my 70-200 on both my 70 and D2H for over a year without any problems. Great lens! Edited on Nov 29, 2005 at 05:55 PM Nov 29, 2005 at 03:37 AM

brandofamily Offline Image Upload: Off p.1 #5 · Sigma 70-200 Troubles..... Could you explain the "freak out on my D70 every now and then" comment. I'm wondering if I need mine worked on. I use it on my D70 too and have been told all images look under exposed. I know that's also a Nikon trait, atleast I've read that for the D70. Now I'm wondering about the lens being an issue.

Now I'm wondering about the lens being an issue. I think the OP is referring to AutoFocus trouble that locks-up the lens (typically happens in low light). Turning the camera OFF and then back ON typically corrects the issue. That was the issue with my Sigma 70-200 f/2.8 HSM before I had the chip/board replaced. BTW "MINE" (Philly) is listed for sale in the FM board :-) http://www.fredmiranda.com/forum/topic/315625#2664848 Edited by Philly on Nov 29, 2005 at 12:18 PM GMT Edited on Nov 29, 2005 at 05:55 PM Nov 29, 2005 at 04:57 PM

thebeephaha Offline Image Upload: Off p.1 #8 · Sigma 70-200 Troubles..... When I said "freak out" I meant that the auto focus kinda well.. Freaks out, it cannot lock on the target right anymore. Nov 29, 2005 at 05:55 PM
