The ensuing contributions discuss a number of specific cell types, including ocular surface cells, corneal stromal keratocytes, endothelial cells, crystalline lens cells, and limbal cells, as well as the dynamics and induction of pluripotent cells, potential cell therapies, and gene therapy.

Lightweight carbon fiber lens hood This lightweight, durable carbon fiber lens hood also features a flocked interior that maximizes its effectiveness at blocking unwanted light that can degrade image quality. Rigid, durable mount design Designed to withstand the rigors of professional use, the number...
This extraordinary focusing motor uses ultrasonic vibrations—rather than a gear system—to spin the lens barrel, resulting in nearly silent and ultra-fast autofocusing. If you want to override the AF system, simply take control of the focusing ring—M/A mode enables a seamless transition between...
This helps you ensure that critical focus is achieved and that there are no slight discrepancies between the two individual lenses. Dual Pixel CMOS AF with iTR AF X Canon's Dual Pixel CMOS AF technology uses every pixel on the imaging sensor to detect focus, and also to capture actual ...
Most lenses have a filter thread in the front where you can screw on camera lens filters. These filters cover a range of options, including adding tints or darkening a scene.
Front lens element has a fluorine coating that repels water, oil, and other contaminants and makes the lens easier to clean. Included lens hood features a locking button and a filter window for easier adjustment of rotating filters (e.g. polarizers, variable NDs). UPC: 027242923775 Items Inclu...

The minimum focus distance is measured from the imaging sensor plane with the balance of the camera, lens, and lens hood length taking a bite out of the number to create the working distance. At this lens's minimum focus distance, the working distance is only 0.5" (12.7mm) in front of...
grade lens designed for Nikon F-mount cameras, both FX (full-frame) and DX (crop-sensor). It’s well-suited for various photographic scenarios, including sports, wildlife, portrait, and event photography. The lens comes with a lens hood, front and rear lens caps, and a ballistic nylon ...
Mount a 70-200mm lens on an APS-C-format camera and the angle of view becomes like that of a 112-320mm lens on a full frame camera. While the narrower angle of view does not greatly change the uses list for this lens, these angles of view are less ideal for widely-framed portraits...
