This may seem a dumb question but I was trying to zoom in closer to a a rare bird that I spotted with my 70-300mm G Nikon lens on the D700 and couldnt' get as close as I would like. Was wondering if I switched to DX mode even though it would crop the image - would I get extended zoom range (more like 435mm?)
Thanks Len. What setting do you suggest best to shoot on when out expecting the unexpected nature shot and not getting too close to disturb. What will allow best quality when cropping? I am still a bit unsure about all this as have only just graduated from film.
Though not a D700 owner, my recommendation is to use the FX/DX setting based on the glass you're using. When you're croping down to DX, you're just using the inner portion of your sensor to match the smaller image circle that DX lens provides. If you're shooting with non DX lenses, keep the setting on FX and crop to your desired "zoom" when post processing. No reason to throw out any pixels that will be exposed by the lens you have.
Hope this helps,

Using DX mode simply crops the image in the camera. Nothing relating to image quality or telephoto range is affected. The D700 has many features which allow going straight from camera to printer without post processing and that's just another one of them.
And it allows many with DX lenses to justify upgrading to the D700 without requiring costly lens purchases. But magicly gaining pixels or quality?, no free lunch yet today.
As of today I consider the FX/Dx situation to be a 2 camera setup. D3 or D700 for ultra wide to 70. 70 to long range telephoto, D2Xs and D300. (My setup) When the long awaited D3Xs/D4 arrives we will have a single camera for both formats. 24mp for the wide work and about 12.0 for the cropped version. I want 2 of them now.
