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.
The most common meaning presently is fixed focal length. (A less common meaning is the primary lens in a multiple lens set-up such as in a Twin Lens Reflex camera.) I've no idea why prime.. Some people seem to use it more specifically for a fixed focal length lens with normal perspective. In thus use, for a 35mm camera, a 50mm or 55mm lens would be prime, and a 28mm or 135mm would not. All else being equal, prime lenses have better optical quality than do zoom lenses. They have fewer moving parts, fewer elements, and are designed to perform best at their single focal length.
