All three Nikon 300mm primes outresolve any existing sensor very comfortably right from f4. Absolutely no one could tell at f6.7 whether you took a given shot with the 4002.8 or any 300 prime plus t.c., they're that good. Color is slightly improved with the PF over the D owing to nano coating. The lens is built extremely well. Unlike the new lenses with lots of plastic exterior, the lens barrel of the 300mm f/4D AF-S is made of metal. The rubber focus ring is large and very smooth to operate. There are only two switches on the side of the lens – one for switching from autofocus with manual focus override (M/A) to manual focus (M Weight. At 1440 g (3.17 lbs), when compared to most other wildlife telephoto lenses, the Nikon 300mm f/4 AF-S is very light. For example, it is less than half the weight of both the Nikon 300mm f/2.8G ED VR II (2900 g / 6.39 lb) and the Nikon 500mm F4E FL ED VR (3090 g / 6.81 lb). This makes it a fantastic lens to handhold. I currently have the 300 f2.8 vr1 and 300mm afs f4. Both lenses are remarkable and the f4 price point off planet. Quite often I want more reach that the 300mm lenses coupled with TC's just dont provide. I suggest the 500mm f4 afs plus the 300mm f4 afs for more casual shooting. peace, Ray The Nikkor 300mm f/4E PF ED VR is physically just like the Nikkor 70-300mm f/4.5-5.6G VR, earning it “world’s lightest 300mm full-frame lens” title. Nikon was able to achieve this by using a Phase Fresnel (PF) lens element, which can effectively reduce the need to use complex lens elements for correcting chromatic aberrations and ghosting It is pretty clear that the new 300mm f/4E PF ED VR lens is noticeably sharper wide open when compared to its predecessor. Take a look at the center performance, where the lens shows a noticeable boost in sharpness at f/4. Stopped down to f/5.6 and smaller, the newer lens performs slightly better, but the difference is barely noticeable. Just as with the 70-200mm Canon lens that I mentioned above, this Nikon F4 constant aperture 70-200mm is a great lens for outdoor (in daylight) sports photography. The biggest advantage that it has over a lens like a 70-200 f/2.8 is the weight and price, the F4 70-200mm’s are significantly cheaper and lighter than their f/2.8 counterparts. Focal length: 300mm. Aperture: f/4 – f/32. Minimum focus distance: 1.4m. Filter size: 77mm. Aperture blades: 9. Construction: 16 Elements in 10 groups. Size (Diameter / Length): 89mm x 147.5mm. Weight: 755g. It’s also a ‘FX’ lens, so it will work with all full frame and cropped sensor Nikon DSLRs. Vay Tiền Nhanh Chỉ Cần Cmnd Nợ Xấu.
