The calculator says that the 70-200mm f/2.8 will yield a depth of field of 0.09 feet, while the 70-200mm f/4 will have 0.04 feet. That’s right – at close distances, the 70-200mm f/4G is actually a better lens to use for subject isolation. Now 5 feet is obviously too close, so let’s do slightly more realistic numbers. That said, I’m glad Nikon went this route rather than introducing the 14-24mm f/2.8 first. The 14-30mm f/4 simply has a broader appeal than the upcoming f/2.8 zoom, which will be significantly heavier and more expensive by comparison. NIKON Z 7 + NIKKOR Z 14-30mm f/4 S @ 14mm, ISO 200, 1/5, f/16.0 Lens Size and Weight These are used to block strong light sources, such as the sun, from the lens to prevent glare and lens flare.

The lens hood can screw onto the lens in reverse so that you can keep it on your camera at all times, ready to use. The question is which lens. The Nikkor 2.8 is out of the question price-wise. I am looking at the Nikkor 70-200 f4 instead of the Tamron 2.8 due to weight for use with the D750. Other than DOF considerations of 2.8 vs 4, with the supposedly higher performance of the D750 would an F4 lens be OK? Or will I be regretting the loss of the 2.8 indoors? An update to Nikon’s legendary f/2.8 fixed aperture telephoto zoom lens, the AF-S NIKKOR 70-200mm f/2.8G ED VR II captures stunning full-frame images with remarkable speed. Nikon VR (Vibration Reduction) image stabilization provides 3.5 stops* of blur free handheld shooting, assuring dramatically sharper still images and HD video capture. Nikon 70-200mm ƒ/2.8G ED VR II AF-S ~$2,400 This is the big decision many Nikon photographers will be looking to make: spend $1,000 to get an extra stop of light-gathering ability?

With a constant fixed aperture of f/4 across all focal lengths, the AF-S Nikkor 70-200mm f/4G ED VR is an alternative to the AF-S Nikkor 70-200mmf/2.8 VR II telephoto lens that is intended for a more professional market. Like its big brother, the 70-200mm f/4 is equipped with the latest generation of The Z 100-400 has a variable focal ratio starting at f4.5 on the wide end. It gets successively darker when you zoom in: f4.8 from 125mm, f5.0 from 185mm, f5,3 from 270mm, f5.6 from 380mm. This is a tad brighter than the F-Nikkor and also better than using the Z 70-200 with TC-2.0x which results in a constant f5.6 focal ratio. By f/8, the lenses are a bit more comparable, although the 24-70mm f/4 S still has the edge. By f/11 and f/16, diffraction has evened out lens performance to the point where the two are nearly identical. And here is how the lenses look at 50mm: The Nikon Z 24-70mm corner sharpness drops at 50mm, but unfortunately so does that of the 24-120mm f/4. ZseY2w.
