One of the most common drug-induced injuries is irritation of the lining of the stomach caused by nonsteroidal anti-inflammatory drugs (NSAIDs). NSAIDs can irritate the stomach by weakening the ability of the lining to resist acid made in the stomach.
A 35mm and 50mm prime and a more pro-level (and possibly fast) zoom lens would benefit Canonâs EOS M ecosystem. As good as the EF/EF-S to EF-M adapter may work, there is nothing like native lenses. Please note: this is not the first time we get the suggestion that Canon is working on prime lenses for the EOS M system. The first rumors are more than a year old, and we didnât see new prime lenses for EOS M so far.
Nikkor 28-200 mm zoom lens, extended to 200 mm at left and collapsed to 28 mm focal length at right. A zoom lens is a mechanical assembly of lens elements for which the focal length (and thus angle of view) can be varied, as opposed to a fixed focal length (FFL) lens (see prime lens). A true zoom lens, also called a parfocal lens, is one that maintains focus when its focal length changes. A lens that loses focus during zooming is more properly called a varifocal lens. Despite being marketed as zoom lenses, virtually all consumer lenses with variable focal lengths use varifocal design.
