Introduction

Second series with this combo is using the zooms at 600mm, main reason to buy such zooms. The Nikkor was again equipped with the TC-17II and set to 350mm which results in 600mm.

The full pictures

The camera was set to 100 ISO, it’s native ISO setting. All pictures taken with an aperture of f6.3 for the Sigma and Tamron. The Nikkor went with f6.7 into this series.

First example showing the Nikkor.

Nikkor 200-400 TC17 @ 600mm

Now the Tamron which went surprisingly well with the 400mm.

Tamron 150-600 @ 600mm

And at last the Sigma which again does not perform as in the series done mainly on full frame and the D2x.

Sigma 150-600 @ 600mm

Looking at the plastic puppet for the thin synthetic hair.

Last compare is on the dream-catcher to have a closer look at the feathers and the thin grid inside the ring.

Conclusion

I did several comparisons using the iMac Retina in Lightroom. Looking at 1:1 crops but also 2:1 crops, so at 200%. My ranking is:

  1. Nikkor with TC-17II
  2. Tamron
  3. Sigma
