TC 1.4 for Nikon 70-200 f2.8: I'm happy with the 70-200 but I can seem to zoom enough to capture some of the wildlife I want catch. I'm considering a tc but I don't want to lose...

I'm happy with the 70-200 but I can seem to zoom enough to capture some of the wildlife I want catch. I'm considering a tc but I don't want to lose clarity. My camera is a D7100. Will a Nikon tc 1.4 be enough to help and will I still get sharp shots?

Have you tried using the in camera 1.3 crop mode?

I use the TC14 with the 70-200 all the time. Any image degradation is more academic than practical. AF is virtually unaffected. Love it.

Yes, however, I am still unclear as to the advantage other than the speed.

Thank you. I'm about to purchase one.

For whatever it is worth I have the Nikon 1.7 on my Nikon 70-200 and it works great and agree with Cliff as far as performance. ;)

Using the camera's crop mode is "digital magnification". Using a TC is "optical magnification".

I use the Nikon 1.4x TC with the 300mm f/2.8 lens. If I pixel peep, I can see a very small loss in image quality, but in general, the extra magnification is worth it.

Well, that is not quire right. All the crop mode does is just that - crop it. You lose all the pixels outside the crop. No different than cropping in software except is does give you a smaller file on the memory card.

True, and I should have been clearer. The "digital magnification" happens when you display the image, the cropped version is magnified more.

So to follow your logic an image shot with a 50mm lens on a D7100 is a digital magnification of the same image shot with a 50mm lens on a D600, D610 or D800

If you use the DX mode on the D800, you have virtually the identical image that you would have if you had used the same lens on a D7000. The 7100 would give you a few more pixels that the 7000.

Hey Cliff, hope all is well. Yeah i get that. Just getting my head around the term "digital magnification". We have Full frame sensors and digital magnification sensors. Never thought of it that way. Probably more accurate but doesn't quite roll off the tongue as well. Anand, you may have coined a new term and created a synonym for "crop sensor" :-)

I've been thinking of it as a better term for "reach".
