Vibration Reduction, or twice as much light?
I am contemplating on a new lens, and the Nikkor 24-70 F/2.8 looks good, but it doesn’t have VR. Since it lets in twice as much light than an F/5.6, do I need Vibration Reduction?
The aperture scale goes as follows 1, 1.4, 2, 2.8, 4, 5.6, 8, 11.2, 16…
f/4 lets in twice as much as f/5.6, and f/2.8 lets in twice as much light as f/4.
From f/5.6 to f/2.8 you will therefore let in 4 times as much light, which means if you have a shutter speed of 1/60 you can now have a shutter speed of 1/240. Much better. I would go for the 24-70, it’s really nice and will honestly make you go wow! when looking at improvements. Wide open lenses help with vibration reduction and fast moving objects, while VR only helps with vibration blur, NOT motion blur.
