The Nikon D40 question?
In fact, not his own question:) 1: What are those goals and what a "70-300mm f/4-5.6G Nikon AF Nikkor" means two?: Sometimes I do not want the flash, so when I make the pictures come out as blurY and I can not take pictures of things that move at all. Pleeaaaaaaaaaaaaaaaase Help me! PS. I have a Nikon D40
1. A nikon 70-300mm f/4-5.6G AF Nikkor is a long-range telephoto zoom lens. No autofocus with the D40. Surprisingly, There are two short range zoom, the Nikon 55-200mm VR 55-200mm IS autofocus that works perfectly on your camera. The second is the role of VR (Vibration Reduction) to stabilize the camera when shooting and virtually eliminates blur from camera shake. The 70-300mm VR lens closest runs more than $ 550, but 55-200mm costs about $ 199 and VR version goes for about $ 249. 2. If you do not want to use flash, turn it off. Turn your mode dial to the output image and cross-beam the camera will shoot without using flash. Http: / / www.dpreview.com/reviews/nikond40/page6.asp also need to increase the camera's ISO (level sensitivity to light) to a higher number such as 800 or more. This helps the camera to select faster shutter speeds in the most dark, minimizing blur. This is an excellent user guide I recommend you print. I did the same for his guidance for my Nikon model and have been of great value. Http: / / www.kenrockwell.com/nikon/d40/users-guide/index.htm If you have further questions, please ask, right?
