Causes of Warts. Skin warts are caused by a virus known as human papilloma virus (HPV). There are over 100 sub-types of this virus but only a few infect humans to cause warts on the skin. The virus enters the skin cells and replicated like all viruses do but does not extend beyond the skin.
With top speed full resolution shooting at between 4.5 and 6.5 fps (frames per second) these cameras are not going to be ideal sports shooters (that's where full frame DSLRs like the Nikon D4S and Canon 1D X come into their own).
Canon has announced two lenses for the EF-M mount used for the first time by its EOS M mirrorless camera. The first lenses will be a EF-M 22mm F2.0 STM 'pancake' prime and an EF-M 18-55mm F3.5-5.6 IS STM standard zoom lens. Both are built around a STM linear stepping motors to drive focus.
