I currently has a NIKON D90 camera. This objective harmoniously compléte my first goal NIKON DX 18-105. The FX NIKON 70-300 can be mounted on a camera whose sensor is 24/36 Format (FX = 24/36) .At the end of more and more digital devices will be 24/36 in FX format. this is not the case of Nikon D90 is a DX or a sensor format = 15.8 / 23.6 Also this goal FX 70-300 mounted on a DX camera increases focal lengths. they spend 70-300 on an FX camera, at 105-450 on a DX camera! The 4.5-5.6 aperture is not a feat. But for an amateur use even warned this is not very serious. this goal has the intrégrée stabilization system (VR function). the quality / price of this lens is remarkable. When this is mounted on a DSLR all not really going unnoticed. Caution weight is necessarily the appointment ... Amazon offers this article at a very interesting price. delivery time is very short. The packaging is serious. Objective and supplier: recommendable!
