In both of these images I used my trustworthy (despite being much maligned) AF-S 24-120 VR lens. However, only, one of them has the DX area setting. Which one may be? The one with the colorfully made-up girl, or the window announcement about "patriotic items" going down in price? BTW, these were images from the Swedish Days in Geneva, where we went with our son (he has to learn to travel with his parents some day...).
So, which one is it?
Try again...
Yep...
The reason to do this was to crop in camera at the same time that I maximized the reach of the lens. The nice portrait didn't take me long to shoot, and it benefitted from the framelines that help compose through the viewfinder. Yes, one could claim that I "lose" information by reducing the document to 5 MP instead of using the whole shebang of this 12 MP sensor... but my concern is to get the image, reach where I want, not to produce a file of a certain dimension.
Do you do this often? I found myself doing it for this shot in California, only that instead of my AF-S 24-120 I had my AF-S 24-70.
Not bad for a beginner... At a given moment, having the DX option contributes to extend the reach, get the shot and maximize a telephoto. This image, cropped to look like something shot with a 115 or 120mm lens, simply delivers what I wanted to show: the thrill of going down in a weird, crazy machine, in a sunny, gorgeous and intensely blue day.
