Nikon D7000 AF speed test

I have continued to test the New D7000 and so far it has exceeded my expectations, I think people forget what market this camera is aimed for, Just a few years ago you would have been lucky to get half these features in a top pro body, The D7000 has a new processor,new sensor and new AF system, I would think that these will go into the D400 when it arrives next year with a few enhancements and some new features,
I wanted to give the new AF system a good workout and shoot something that would test it, No point in shooting a heron in flight, a car or a big lumbering dog-No this called for Alfie my Miniature Schnauzer, Show him a stick and he will move at incredible speed, I took him to a beach on a local lake, The sun was high and the sky cloudless, After Alfie had had a dip and run around i set the camera up-AV mode, ISO 800 to get a very fast shutter speed, AF-C with 9 assist points, Its very important to get a very fast shutter speed when testing the system as you don't want to wonder if a soft image is due to motion blur, I had taken some shots at around 1/400 and although a few were very sharp there was some that were not-my bad as they say here so ISO 800 gave me in excess of 1/3200 which should be more then enough, I shot continuous bursts until Alfie was at my feet and we shot until he slowed down and was getting tired-nearly 200 shots,
Here is a typical burst


6.AF focused on body

 7a-100% Crop

9a-100% Crop
10.Focus on body

So not 100% but the 2 that mis- focused on the body rather then the head i think is more to do with the way the dog runs i.e head up/head down and also down to me, Its very difficult to keep the AF point directly on the head when he is moving so fast, At no point did the focus grab anything else, It stayed on the subject and if it focused on the body in one image by the next frame it was bang on the head which is amazing for such a small fast moving subject
All images are straight from the camera and the only processing was some sharpening-All full frame
I used a Nikon 70-200VR2 which is great lens and will certainly help in situations like this, As i said at the start of the blog, The D7000 has exceeded my expectations in every departments, The IQ here is great and dont forget these are ISO 800 without any NR-I would not have managed that with the D300!! The AF system seems very solid-not jittery like i said before, Once you are locked on it stays with the subject and as long as you have that all important shutter speed you will get great results-oh and a decent lens helps no end



  1. Nice results. What would be cool is to see the same sequence on video so we could see how fast the little pooch is...

  2. Thank you for sharing your experience of the new Nikon AF multicam 4800 DX.
    Maybe the new metering 2016pixels can also help to locate and keep the subject in focus.
    This new D7K seems to give a lot for such a little body of this price level.

  3. Thanks for sharing some information regarding the AF system of the D7000. It's great to hear that the results are on par with the D300 and the better noise performance definitely gives the D7000 added advantage. Personally for me, ISO 800 on the D300s is the limit at which I can go, and even so, the noise levels are already quite bad.

    But with this release of the D7000, we can probably expect something much better with the announcement of the D400 next year (if it's really coming) :)

  4. Nice info-did you use the 11 point or 39 AF points, with the AF-C 9 point?

    I shoot alot of birds in flight.


  5. Dave,

    I tried this with my 18-105VR lens and couldn't get photos that were quite as sharp. It seems like the focus wasn't fast enough. Is the 18-105 focus that much slower? Also, I had Focus Tracking (A3) set to Normal. Should I have set it to Off?

  6. I have spent so long not only searching for a camera but also a review that addresses the single one issue I have (AF on dogs running towards me). Thanks for the review
