A funny thing happened as photographic technology became better and better: lenses got smarter, but photographers?—not necessarily.

Yes, modern lenses are ultra-sharp and super-contrasty, they focus automatically, and undesirable artifacts like chromatic aberration and barrel distortion have improved. However, autofocus technology has brought three critical changes that serious photographers need to consider carefully when they choose their lenses, because they can be a hindrance to thoughtful photography if not used carefully.

Welcome to Part 1 of a three-part series that lays out the basics of lenses for novices and those who could use a refresher. In this part of the Lens Primer, Larry Becker, of Kelby Media, explores concepts such as aperture, image stabilization (IS) or vibration reduction (VR), and telephoto zoom lenses versus primes.

In this video from B&H, Larry Becker offers a basic introduction to the challenges of, and solutions for, shooting in low light with a DSLR or mirrorless camera. He explains ISO sensitivity, shutter speed and aperture settings and demonstrates how simple in-camera adjustments will provide marked improvements when shooting indoors.

Hands-on Review

The number of fast, wide aperture prime optics we carry at B&H has grown over the past year, and in a market that has become increasingly populated by slower, variable-aperture zooms, this is encouraging news.

Olympus has just announced a new addition to the Micro Four Thirds system, the M.ZUIKO Digital 17mm f/1.8 lens. This lens offers a 35mm equivalent focal length of 34mm, giving it a slighter wider-than-normal angle of view that is ideal for general everyday use.

It’s interesting to note how many photographers, even advanced shooters, are mistakenly under the impression that the depth of field (DOF) of a variable-aperture zoom lens changes in relation to the effective aperture of the lens as you zoom toward the telephoto end of the optic’s zoom range.

The aperture of the lens controls the amount of light that passes through on its way to the camera's sensor or film plane. A camera's aperture is also commonly called its f-stop, though 'f-stop' technically refers to the diameter of the opening created by internal adjustable blades, rather than the entire mechanism.

Most professionals (and serious photographers) working digitally, shoot RAW files. They usually do so because of the incredible degree of control and the higher image quality that comes with RAW files. Being able to correct white balance after the fact is one of the many great things about RAW files. The worst thing about RAW files, in my mind, is what I call the ongoing proprietary RAW file wars. In this blog entry, I will talk about what you need to know to stay clear of the RAW format wars.

White balance is the nearest digital equivalent to “daylight film stock” or “tungsten film stock.” The actual response of the image sensor to light is designed and fixed at the point of manufacturing, so adjustments for white balance are done electronically.
