This review is from: Nikon D700 12.1MP FX-Format CMOS Digital SLR Camera with 3.0-Inch LCD (Body Only)I am making this review of the Nikon D700 from the perspective of someone who also owns a Nikon D300.Without qualification, the Nikon D300 is a superb camera. So many superlatives have been used with the D300 that I will not repeat them here. All the superlatives used with the D300 applies equally well to the D700. I will add however that as good as the superlatives may have been with the D300, the D700 deserves a bit more. Let me explain.The Nikon D700 is equipped with a full frame FX sensor (36.00mm x 23.90mm). This is the same sensor used by the Nikon D3. Nikon D3 12.1MP FX Digital SLR Camera (Body Only) The D300 on the other hand uses the APS-C sensor (23.60mm x 15.80mm). Both the D700 and the D300 have about the same 12 megapixel rating (with the D300 actually slightly higher). The D700 having a bigger sensor than the D300 but with about the same megapixel rating means that the size/pixel density of the D700 is much lower than the D300. The ratio is 1.4MP/cm2 vs 3.3MP/cm2 for the D700 and the D300 respectively. A lower ratio means lower noise and this ratio favors the D700. For the D700, this translates to lower noise in capturing the same image than when using using the D300.The D700 lower noise level in turn translates to the D700 being able to operate at a higher ISO level than the D300. The D700 can operate as high as ISO 25,600 while the D300 can go up to ISO 6,400. It is of course quite rare to shoot at such high ISO as it will always be better to shot at a lower ISO rating. But if both the D700 and D300 were shooting at the same ISO, the D700 will have lower noise levels. Simply put, the higher ISO capability of the D700 versus the D300 indicates the higher level of performance of the D700's sensor vs the D300. My actual use validates this theoretical advantage. I noticed that while the noise level of the D300 is very good at ISO 1600 and even 3200, the D700 consistently showed lower noise level than the D300 shooting at the same ISO setting and light condition. This is most noticeable when shooting at night with many bright lights in the periphery of the main subject. In terms of color rendition, I have not noticed any significant differences between the D300 and the D700 in the limited time that I have been using the D700. It may be due to the fact that I have conducted my test at dusk and at night.When using the D700, the full frame sensor means that one will not need to convert the focal length of the lens by a factor of 1.5x. So a 50mm lens will be a 50mm lens for the D700 rather than its 75mm equivalent when used with the D300.While this may appear to be a disadvantage on the telephoto side, its gain on the wide angle side is considerable and can only be described as an eye opener. The D700 advantage in wide angle application does not just come from its wider perspective. Rather, it is how the D700 maximizes and makes full use of such excellent lens as the Nikon 14-24mm f/2.8 that makes buying the D700 such an eye opener. The resulting images taken with the Nikon D700 and the Nikon 14-24mm are clearer, sharper and crisper compared to the D300 even when the focal length in the D700 is zoomed out to its equivalent in the the D300 (21mm in D700 and 14mm in D300). Vignetting is not noticeably worse even when the D700 is used with the 14-24mm glass fully open at its widest focal length (14mm, f/2.8). This is surprising considering that the D700 is now using the full lens instead of just its sweet spot in the center (which would have been to the advantage of the D300 due to its APS-C sensor).It is not just the wide angle lens that benefited from the D700. Even the slight vignetting I noticed with my 85mm f/1.4 shot with the D300 at f/2.8 is not considerably worse in the D700. I am very surprised at this rather unexpected results as I had expected the opposite. At any rate, vignetting is easily corrected in post-processing.Still, I should add that for corner to corner sharpness (such as in landscape photography), the D700 with its full-frame sensors will be more demanding on the lens than the D300 with its smaller APS-C sensor.As to the physical differences between the D700 and the D300, while these two models are roughly equal in size, the D700 is slightly heavier than the D300. This is not an issue for me at all. What tilts the balance in favor of the D700 is its view finder which is significantly brighter and better than the D300. This difference is very noticeable when switching from the D700 to the D300 and vice versa.This much improved viewfinder however is a mixed blessing. One disadvantage that the D700 has over the D300 is that the D700 viewfinder captures only 95% of the image while the D300 viewfinder captures 100% of the image shot. So the actual image captured is slightly bigger than what appears in the D700 viewfinder. I understand that this resulted from fitting the bigger sensor from the D3 into the body size of a D300. Given the better image quality of the D700 viewfinder and the better quality of its pictures, I am willing to work with this disadvantage and simply compensate for it during actual use. But I hope that Nikon corrects this though in its next iteration of the D700.The D700 has an advantage over the D3 as it has an integrated flash which the D3 does not have. The integrated flash is e...
