D7000 + 35mm/1.8 - what AF correction do you use?

Calibrated the D7000 with 35mm/1.8 - slight backfocus - corrected with -5 setting.

Took a few shots in an industrial museum today after calibrating - was able to get much better focus point control - see pic - focus point on pinion gear. About 1 foot distance at f/1.8; ISO 6400.

Mine needed -20. Pretty sharp now, but wish I could try further beyond -20.

Re: D7000 + 35mm/1.8 - what AF correction do you use?

mine also needs -20 and is still back focusing, also has some general back focusing with my other lenses, I have done some test photos and is bringing my D7000 into Nikon this Friday, hopefully they can fix them all

-2 on mine.

But just out of curiousity. What do you intend gain from getting answers? A possible miscalibrations is unique to each individual lens/camera combo.

Say you get 20 replies with an average of +5 adjustment.

Would you then adjust your own finetuning altough you know it isn't optimal for your specific combo?

Re: D7000 + 35mm/1.8 - what AF correction do you use?

I suspect the reason why the adjustment goes + - 20 is because that covers most of the tolerance differences between lenses and bodies. + - 5 is nothing to worry about IMO.

Now if you are at + - 20 you might think about having Nikon take a look. Especially if it is with more than one lens and/or you feel like you need more adjustment than + -20.

Just wanted to see if my body was ballpark normal.

Same here, -20. I might send my D7000 into Nikon. Seems pretty extreme.

I think it's an interesting question, dbbarron--if you could assemble sufficient data points, it'd be intriguing to see if there were any pattern.

For what it's worth, mine likes a -5 correction. Something else: I've read a few threads, now, with people talking about the corrections they've employed for this lens, and I've never seen anyone using a + value. Anyone out there using + ?

Curiouser and curiouser.

Cheers!

-20 (on 2 different D7000 bodies). Had the lens checked by Nikon service (UK) and they confirmed lens was calibrated correctly!

Re: D7000 + 35mm/1.8 - what AF correction do you use?

Yeah, I also read the US Lensrental article about tolerances between lenses and bodies and how they ought to be acceptable. Thing is, I never had this issue of needing to calibrate my lenses with my D300 or D300s, or D700 - only with the D7000, where my Sigma 17-50mm f2.8 needs -8 and I just could not get consistent sharp focusing on the new Nikkor 50mm f1.8G no matter the setting.

The short of it is, I've sent my D7000 to Nikon for calibration...

Unfortunately it says little about just your body as the lens is the second factor..

You really shouldn't look at other peoples combo too much, as just your own is relevant for you. Other peoples AFtune settings have absolutely no influence whatsoever on your output. If you get sharp images at -15 then mission accomplished.

The only then when you need to worry is when your lens/camera combo is unable to get sharp results even with AFtuning at it's limits. Then it's time to let your local Nikon Service Point have a look.

None at all – seemingly one of a very small minority.

-11 for me

That's mean you have to change the calibration depending the lighting conditions??

It is a normal procedure in Nikon cameras or just the D7000? I can't believe a $1400 camera has some many issues and discrepancies with AF, WB.

Some people state this is a "very sophisticated camera" but I never had this issues with my modest professional Olympus cameras.

Me too. All my other lenses (have five in total) are just fine and need no adjustment. Agree with the previous post that nobody even seems to need a + adjustment.

Re: Nightrider72

Yes, it works better if I fine tune to -10 when under tungsten light.
I don't know if other cameras are prone to this kind of behavior...

Re: D7000 + 35mm/1.8 - what AF correction do you use?

I was disappointed with soft images without fine tuning the lens on a d7000. I jumped to -20 and found acceptable results.

I'm suprised the lens needed that much correction. And, because I hit the limit on how much the lens could be corrected, I am wondering if it could get even sharper?

Also, I hope I fine tuned the lens for a universal range of subjects. This was more for full body portraits, at f/1.8-2.8.

I don't want to have to re-tune the lens every time I shoot a different subject.

I have little experience with this, as most lenses have worked on my other Nikons without adjustment...

I have this lens and it's bang on with the D90 and I've torture tested it I can assure you

I've not spent enough time with a D7k but I would not expect to have to make an adjustment to that degree. Something seems wrong there
