Large maximum aperture of f/2.8.
Such as using a setting of f/4.0 on a lens with a maximum aperture of f/2.0.
Lenses with larger maximum apertures are typically much heavier, larger and more expensive.
This lens consisted of seven elements in three groups with a maximum aperture of f/2.
Variable maximum apertures Zooming the lens from 10mm to 24mm decreases the maximum aperture by 2/3 stop.
Gas diffusion head: Maximum aperture:< 80μm.
Lenses typically have fewer aberrations when they perform the exposure stopped down one or two f-stops from their maximum aperture.
And a lens with a large maximum aperture leads to the best results when shooting in unfavourable light.
Zooming the lens from 28mm to 300mm decreases the maximum aperture by 1 1/3 stop.
The relatively large maximum aperture(f/1.7) allows the photographer to take shots indoors even when operating at ISO 100- 200.
These aperture ranges therefore refer only to the range of maximum aperture, not overall range.
Variable maximum apertures Zooming the lens from 18mm to 200mm decreases the maximum aperture by 1 1/3 stop.
Ideal for use in a wide range of light conditions, the f/4 maximum aperture stays constant over the full focal-length range.
The maximum aperture is perhaps the most important lens aperture specification, which is often listed on the box along with focal lengths.
Type G AF-S lens with built-in CPU and F mount Focal length 70- 200 mm Maximum aperture f/4 Lens construction 20 elements in 14 groups including 3 ED lens elements and lens.
Even at maximum aperture after canceling the aperture stop-down, the preset aperture value is displayed on the camera body.
The primary benefit of having a zoom lens with a constant maximum aperture is that exposure settings are more predictable, regardless of focal length.
At the other extreme, using a subtle 1:8 fill flash might be impractical if there's very little ambient light andyour lens doesn't have a large maximum aperture.
Also note that just because the maximum aperture of a lens may not be used, this does not necessarily mean that this lens is not necessary.
For SLR cameras, the number andaccuracy of autofocus points can also change depending on the maximum aperture of the lens being used, as illustrated above.
The shallow depth of field at maximum aperture allows the creative combination of focus and blur, allowing you to direct the viewer's attention to the main subject of your photo.
This can make it very hard to discern changes in sharpness-particularly in low light, orwith tilt shift lenses having a maximum aperture of f/3.5 or a wide angle of view.
Features a large maximum aperture of f/1.4 that ensures a bright viewfinder image, and is ideal for low-light shooting situations or when a shallow depth of field is desired.
Even if you intend to exposeusing a small aperture, a lens with a large maximum aperture can greatly increase viewfinder brightness during composure.
This*may* therefore mean that if one wanted the best quality f/2.8 photograph, a f/2.0 orf/1.4 lens may yield higher quality than a lens with a maximum aperture of f/2.8.
Finally, some zoom lenses on digital SLR andcompact digital cameras often list a range of maximum aperture, because this may depend on how far one has zoomed in or out.
Thanks to its maximum aperture of f/2.8, the reflection-free and practically distortion-free super wide-angle lens is perfect for spectacular image compositions of great diversity, dramatic contrast and vivid colors.
This is an important consideration when choosing a camera lens: even if you do not plan on using a lens at its maximum aperture, this aperture may still help the camera achieve better focus accuracy.
