因为Nikon 70-300mm 是FX 镜头，而18-300mm是DX镜头，他用的相机是Nikon D7000 是DX-Format CMOS sensor， DX sensor 象素范围是小于FX sensor 。

以上圖的展示為例，FX 鏡用在 135 全片幅底片的成像面積是最外圍的青色範圍內，而當放置在 DX 型上便變成只有 1.6 Crop Factor 的粉紅框內範圍，對嗎？

那麼以此推算，樓主所拍攝的圖片顯示範圍較大的圖片便是由 70-300mm 所獲得的嗎？

If you use an FX camera ( Nikon D7000) you can still use both FX and DX lenses. If you use an FX lens, you get the full-frame image at the full resolution the camera offers. If you use a DX lens, the camera will automatically crop the image to account for the smaller image being projected onto the sensor. You also get a reduction in resolution. This is because the image being projected onto the sensor from the lens, is actually smaller than the sensor itself. Basically the camera adjusts for the fact that the outer edges of the sensor are not receiving any light/image from the lens.

答案是圖片二係由AF-S DX NIKKOR 18-300mm f/3.5-5.6G ED VR影的.
        第二組照片也是由AF-S DX NIKKOR 18-300mm f/3.5-5.6G ED VR影的.
感謝觀看

圖片2 color is richer than 圖片1
第二組照片is a bit better than 第一組照片, they are very close.
我認為圖片2 is 18-300mm
第二組照片 is 18-300mm
I think the bigger the lens the better color, (18-300 F3 ...
