Z lenses, perfectly matched to Z camera bodies, are designed with a sense of consistency that combines reliability and beauty with the next-dimension optical performance for freedom in image creation. (backscatter.com)
The lens is equipped with a built-in optical extender, which can instantaneously double the focal length at the touch of a button (2,000mm for D60x16.7SR4 Series and 1,500mm for D60x12.5R3DE Series). (fujifilm.com)
Combining impressive optical performance with lightweight, compact convenience, the SEL2870 makes an ideal everyday lens. (sony.com)
Built-in Optical SteadyShot™ image stabilisation within the lens ensures smooth, blur-free photos and videos when shooting handheld. (sony.com)
With a LEICA DG Lens you shoot with the ultimate in optical quality and performance. (huntsphotoandvideo.com)
With IF Lenses all optical movement is restricted to the interior of the lens barrel, providing for a lighter, more efficient design. (focuscamera.com)
Only the middle groups of the optical system move to achieve focus, so the overall length of the lens does not change. (rockbrookcamera.com)
Inside, the lens sports 9 rounded blades and a new optical design of 12 elements in 8 groups. (videomaker.com)
It's interesting to note that the lens has electronic parts that help adjust for parallax when using it with the optical viewfinder. (fredmiranda.com)
Lens configurations: 6 lens elements in 4 optical groups. (fredmiranda.com)
The control of optical vignetting in this small lens is quite impressive. (fredmiranda.com)
The APO optical system delivers stunning image quality through premium, high density, extra-low dispersion glass. (romanceuniversity.org)
A lower peak power enables larger amplification without the risk of damaging optical components. (lu.se)

And for the first time in a full-frame ultra-wide lens, the creative and practical flexibility of attachable filters. (backscatter.com)
Weighing only 200 grams, this small full-frame lens is an ideal match for α7 series bodies and a convenient choice for snapshots and everyday use. (sony.co.uk)
The SP lenses can cover full-frame or APC-S sensors and are encased in a robust barrel frame with smart switch locations, intuitive response, smooth mechanical operation, and balanced barrel-weight proportions. (nofilmschool.com)

Thus, IF NIKKORS do not change in size during AF operation, allowing for compact, lightweight lenses capable of closer focusing distances. (vistek.ca)
Its Internal Focus (IF) provides fast and quiet auto focusing without changing the length of the lens, so you can retain subject to working distance through the entire focus range. (pictureline.com)
Nikon's Internal Focusing feature allows you to focus a lens without changing its size. (focuscamera.com)
Faster focusing is produced by a lighter and compact focusing lens group. (focuscamera.com)
The ED Glass (Extra-Low Dispersion) lens in Quasar ® Plus has been lowered for a better and improved focusing system for sensors in deeper cavity. (visibledust.com)
As focusing is performed internally, the front filter thread does not rotate, making this lens ideal for use with graduated filters, polarisers and macro ring flashes. (ephotozine.com)
That's a phenomenon in which the lens' field of view changes during focusing, which can be particularly distracting during video capture. (popphoto.com)

This explains why lenses with larger apertures are more expensive: they require more glass inside larger barrels. (overclockers.com.au)

Alot of people lament that this isn't a stabilized lens, but if I use it on a camera that has in body stabilization, then it's ok yes? (bhphotovideo.com)
VR image stabilization for sharper handheld photos and videos in low-light situations and at telephoto distances. (indymogul.com)
Based on image stabilization performance levels established the CIPA (Camera & Imaging Products Association), Tamron says that while in VC Mode 3, the lens effectiveness is equivalent to 4.5 stops. (nofilmschool.com)
Gyro sensors built into the lens detect even the slightest movement, and the stabilization lens is precisely shifted to counteract any image blur that might occur. (rockbrookcamera.com)

Praised for its reliability and overall image quality, this is a long-time favorite lens of passionate professionals. (pictureline.com)
Image Stabiliser technology allowing a photographer to shoot three-stops lower than without VR. (overclockers.com.au)
A prime lens of unparalleled image quality and construction, hand made to the highest quality. (overclockers.com.au)
This is a lens designed for maximum impact and image quality. (visions.ca)
3 Less light is transmitted by any lens at the image periphery. (sony.co.uk)
This is caused by differences in refraction at different points on conventional spherical lenses which degrade image quality in large-aperture lenses. (rockbrookcamera.com)
The lens controls vignetting effectively, so you won't have strong darkening at the corners of the image. (fredmiranda.com)
