Hi everyone, a newbee here and plan on upgrading after playing the site for a few weeks. My question is I have all Nikon glass from my D80 a few AFD lens and some newer G lens also. I wanted to buy a new long lens for wildlife like a Sigma 150-500mm model and maybe use a Sigma 1.4 TC with it when needed.The reason for the choice was advantages of the D7000 and settings. I read on one site that the new D7000 is the 1st model from Nikon that might have compatability issues with outside lens manufacturers like Sigma. Does anyone know about this? And any input on Sigma newest version (non recalled) of course 150-500mm model lens? As an FYI I did email Sigma the question about this any they gave me a vague we are in testing right now with our lenses and the D7000. It will be posted on their site when done. OK where do you find that update I asked with no response from them. But I do look forward to being on this site and learning more as I keep moving from 1 Nikon to the next in my life. Thanks Dave
The situation with Sigma lenses is not unique to the D7000. Several previous Nikons have resulted in Sigma needing to develop and issue a "firmware" fix for at least some of their lenses.
I believe this happens because Sigma choose to use "reverse engineering" to design the electrical interface of their lenses rather than take (and pay for) the relevant data from Nikon. When Nikon change something in the interface spec, Sigma have to respond. They invariably do, given time
I have not had any Af problems with my Sigma 150mm macro or 10-20mm while shooting photos but neither of my lenses will AF correctly in live/video mode. I don't find this a problem since I will me manually focusing my Sigma 150 for macro shots anyway and don't intend to try to use the 10-20mm with AF in live view/video either.
Hi- I own a three Sigma lenses and a D7000. The only problem lens that I have encountered issues with the D7K, is the new Sigma 120-400mm F4.5-5.6 APO DG OS. What was the issue...sporadic auto focus. Sometimes it worked and sometimes it did not, no particular regularity as to why there was an issue? I ended up taking the lens in personally to Gentec International, last week, our warranty service in Toronto Canada. They agreed that there probably was an issue and are fixing the lens? I hope they will contact me this week, especially because they will be closed for a week during Christmas holidays. I will re-post to let you know the outcome. What works on my D7K: Sigma 18-50 F2.8 EX Dc macro Sigma 18-250 F3.5-6.3 OS Tokina 11-16 F2.8
Hi! I have the D7000 and a Sigma 150-500 F5-6.3 APO DG OS. Bought the lens 5 months ago, and have had no issues at all so far. Can't say much about that specific lens and problems with LV autofocus though since I have to 98% been using it with the viewfinder.
Good luck /Timmy
Ed: Just noticed the thread was from dec, and I'm afraid I don't have any experience with the Sigma 24mm f1.8 as questioned below, sorry!
Realizing, of course, that I'm hijacking another's thread...
Anyone out there have experience with the older Sigma 70-200/2.8 EX APO HSM (non-DG) lens and the D7000? I believe there were some AF-ON compatibility issues with this lens and cameras which had this button (D200, D300, D700, etc) which required that the lens be rechipped. Anyone found any other issues with this one?
