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).
Save. In digital camera terminology, the term DSLR stands for digital single-lens reflex camera. A DSLR camera operates differently than a standard point-and-shoot digital camera. Some defining characteristics are full manual control of camera functions and the ability to attach with and utilize separate lenses.SLR Technology. Digital SLR cameras use a mirror within the camera behind the lens mount but before the image sensor. This mirror, in conjunction with a prism, means the photographer sees through the viewfinder the actual image that will be taken.
