How to choose a lens? Image quality often depends on the lens to a greater extent than on the camera itself. If you own a DLSR camera, the capabilities of a full-time kit lens are most likely not enough for you. However, the range of lenses is so wide that it is reasonable to resort to renting lenses, and not to buy the entire line.
Lens Options
Focal length
The most important characteristic, measured in millimeters. For full-frame cameras and for cameras with a reduced matrix (crop, cropped, DX) produce a variety of lines.
Lens models for FX DSLRs (full frame):
- super wide-angle - 7-8 mm (fish eye, fish eye, fisheye) - 24 mm
- wide-angle - 24-35 mm
- standard - 45-55 mm
- telephoto lenses - from 85 mm
Crop factor. For Canon cameras is 1.6; for Nikon, Sony, Pentax and Samsung cameras - 1.5; for carcasses Olympus and Panasonic - 2. We multiply the value of the focal length of the lens by this factor, we obtain the focal length on the cropped mirror.
Aperture
Aperture characterizes the degree of illumination of the matrix of a SLR camera or film. The smaller the number in the denominator, the greater the aperture ratio, the more light reaches the matrix. That is, ceteris paribus, the shutter speed may be shorter. The higher the aperture, the stronger the lens is able to blur objects out of focus. In other words, fast lenses create a shallow depth of field (DOF). Typically, such lenses provide high image sharpness and fewer aberrations.
Stabilizer
Reduces blurring (shake) at slow shutter speeds. Unstabilized lenses, as a rule, are cheaper than stabilized lenses. A stabilizer can help with increased shutter speeds in low light conditions (less likely to get blurry photos).
Autofocus, autofocus drives
Modern Canon lenses come with a built-in autofocus motor. Nikon, Sony and Pentax lenses come with both a built-in autofocus motor and a “screwdriver” (focusing is done using the camera’s motor). Not all Nikon cameras have a motor, which means that screwdriver lenses are not able to autofocus.
There are budget lenses where the entire frontal group of lenses moves when focusing. This is inconvenient if polarized (polarizers) or gradient light filters are wound. Filters are available for rent in Moscow, as are adapters.
