Looking to buy a camera but overwhelmed by all the choice? Our expert guide on how to buy a camera reveals 5 crucial DSLR tips covering sensors, pixels, shooting modes, interfaces and everything else you need to know when buying a camera.
Pentax has announced a new DSLR to sit in its line-up, featuring a weatherproofed body and shake-reduction technology.
The company says that the features found in the K-30 are more commonly found in higher specced cameras, but the body shape and size is more reflective of an entry-level model.
Featuring a 16.2 million pixel CMOS sensor and a PRIME M image processor, which enables the K-30 to shoot full HD video at 30fps. A wide sensitivity range of between ISO 100 and ISO 12,800 (expandable up to ISO 25,600) is also available.
Does your lens has more letters after its name than a retired rocket scientist. What do all these lens markings mean? You can refer to a lens simply by the name of the manufacturer, the focal length, and its maximum aperture – a Sigma 70-300mm f/4-5.6, say, or Canon 50mm f/1.4. But as lenses have often evolved from decades of development, they usually have a line of additional letters after their names, stamped on the barrel or printed on the boxes.
Some lens markings are about manufacturer branding – defining a more recent range, or a lens that’s built to higher standards than another. Others are to do with the optics themselves, and to highlight specific technologies used in the lens construction. In the jargon-busting guide below, we’ll translate these lens markings for you.
