Just Zeroed my Lens in on the AF

[Mr Bump]

Well only signed up yesterday and having read a few of the topics had a go at fine tuning the auto focus for my 70-300 VRII. After quite a few pics of my fave test which is a tiny BT sign nailed to a telegraph post over the other side of the road it seems its +5 also I read the sweet spot of this lens for my D7000 is F8 which I have to also agree.

With this set at 1/250 with VR on my pics are perfect down to pixel level at the full 300mm handheld.

I spend most of my time @ 300mm on this lens as its usually pretty little birdies

happy days

I really should take the time to micro-adjust my lenses, I'm sure they need it :|

Feel a little more inclined to do it reading your success!

Just tried this with my 18-55mm kit lens and 35mm 1.8 on my D7000.
The 35mm was pretty much spot on, the range was -13 to +12 which put the midpoint at basically 0 or -1.
The 18-55mm i did it at both the 18mm and 55mm ends and get very different results. At the 18mm end the range is -8 to +16 so the mid point would be +4. At 55mm the range is -12 to +11, so mid point is 0 or -1.

The D7000 does allow you to tune 12 lenses and 100 saved tune points for each lens so you can change the tune point from ones you've saved in the past. A bit of a pain on a zoom lens to constantly switch tune points though for the focal lengths but at least you can do it, and with a prime lens once tuned you don't even have to think about it.

I went out and took a few pics this afternoon with the new settings and its pretty close to be honest the difference for me is moving from wide open @ F5.6 to F8 as other folk have said it has sharpened my pics up at 300mm quite a bit even heavilly cropped.
