“I think the hardest thing about macro photography is actually previsualisation — learning to recognise what a good macro subject might be,” says Long. “Because when you’re going into macro distances, things just look completely different than what you see in the real world. You might be...
a camera is a device that captures light and processes it into an image. it does this through a lens, which focuses the light onto a light-sensitive surface where a picture is formed. this could be film in traditional cameras or an electronic sensor in digital cameras. what are the key ...

There is a relatively new 90mm OM System macro lens that goes to 2X, which means at 2X it see a subject about 9mm wide. To photograph a 9mm-wide object with a full-frame camera (filling the frame) you would need 4X The definition of magnification has nothing to do with lens focal le...
The dive site below theSeaventures Dive Platform in Mabulis a good example of this. Below this converted oil rig, and among the rubble that clutters the sea bed, is a richness of small creatures that has made this one of the best macro dives in the area. The bay wall of Banda Neira...
How Is Focal Length Measured? Camera lens manufacturers measure the distance between the point of sharpest focus and the camera’s sensor (or film). That is the focal length of the lens. They then label each lens with its measurement in millimeters (mm). A Canon zoom lens with a 16-35...
Another accessory connecting a camera to its lens are hollow extension tubes. They have no optical elements, and therefore do not convert a lens’s focal length. The extension decreases the focusing distance of a lens, and increases magnification; it is used for macro, or close-up photography...
Along with focal length, a lens also has a diaphragm that can change size – commonly calledaperture– which controls how much light is let through the lens (part of how we controlexposure). As your aperture changes, it looks like this: ...
Sony, is going to be more expensive because you will probably need to buy new lenses as well. A used R10 could probably fit, but not the R7. And he would need the adapter to use his lens(es), so count another 100 bucks. I do not recommend the R50 for sports, it has good AF ...
