Does your Nikon D90 have problems focusing with third party lenses?
My Nikon D90 has no problems focusing perfectly when I use Nikon lenses, but about 70% of third party lenses I have tried (Sigma 24mm 1.8, Tamron 17-50mm 2.8 and 17-50mm 2.8 VC) either have front or back-focusing problems. My Tamron 70-200mm 2.8 DOES work like a charm though, so thank the lord for that.
Has anybody been having a similar problem? It definitely sounds like the body is off, but then why would all my Nikon lenses be perfect?
I don't do Nikon but yes with my Canon cameras. I have a Tamron 18-200 that worked pretty good when I received it but now it's in a drawer and will stay there. Aberration problems to boot.
Focus: The lens roams all over trying to find it. When it settles down the shot is still out. I find exactly the same result with my Canon lenses.
This is why I always recommend against 3rd party lenses.
Oh dear, Jim and his crusade against 3rd party lenses again.
Weird. How much off are they? Sigma 's kniown for that but 2 tamrons… I think it's not the body but either you examining your collection with a microscope or just really bad luck picking lenses.
Both Tokina lenses that i tried have backfocus issues on my D90 - i don't mind them on my 11-16/2.8, as i focus manually on close things anyway, and on distant ones it's not an issue with an ultra wide angle lens. With the 50-135/2.8 it was so severe that i had to return it though, as for shallow DoF work it became nearly impossible to use.
That of course certainly is not a "normal" thing, especially for a high quality brand as Tokina. I'll buy the 50-135 again without hesitation once it's available back at the store from being sent to calibration, i've arranged that they call me when it returns.

I may have had bad luck.So… Count it as anecdotal evidence, nothing more.
