Good sources of sulfur are animal-based protein foods, such as meats, fish, poultry, eggs and milk, but there are also some plant-based food sources of sulfur, such as wheat germ, legumes, nuts, Brussels sprouts, and some smelly veggies, like onions, garlic, asparagus and cabbage.
Canon EF-S lens mount. The Canon EF-S lens mount is a derivative of the EF lens mount created for a subset of Canon digital single-lens reflex cameras with APS-C sized image sensors. It was released in 2003. Cameras with the EF-S mount are backward compatible with the EF lenses and, as such, have a flange focal distance of 44.0 mm. Such cameras, however, have more clearance, allowing lens elements to be closer to the sensor than in the EF mount. Only Canon cameras released after 2003 with APS-C sized sensors support the EF-S mount. The S in EF-S has variously been described by Canon as coming from either Small image circle (the lens projects a smaller image circle than normal EF lenses to match the sensor), or Short back focus (the smaller mirror used in APS-C cameras also allows optical elements to protrude further into the camera body, reducing the minimum distance between the sensor and the back element of the lens).
The Canon EF Cinema Prime Lens Kit from B&H includes three prime lenses for use on Canon EF-Mount cinema cameras. A 24mm T1.5 wide angle lens, a 50mm T1.3 normal lens, and an 85mm T1.3 telephoto lens will provide you with three key focal lengths. Each lens features matching physical dimensions.
