Interchangeable-lens cameras come in two types: DSLRs with optical viewfinders, and mirrorless cameras with electronic viewing.
DSLRs traditionally have relatively large handgrips, while many mirrorless models have much smaller grips to keep the size down. However, some can accept accessory grips to improve handling with larger lenses.
Each camera brand uses its own lens mount, and mirrorless cameras use different lenses to DSLRs even from the same brand. However, mirrorless models can often use DSLR lenses via a mount adapter.
Entry-level cameras tend to have simple, Easy-to-understand controls, while more expensive models add lots of buttons and Dials To Give Quick access to settings.
The biggest difference between DSLRs and mirrorless cameras is that the latter use electronic, rather than optical viewfinders. They’re more power hungry, but can display more information and show exactly how your pictures will turn out.
Size and Weight
Mirrorless models tend to be smaller and lighter than DSLRs, and not just the cameras themselves, but their lens systems, too. However, there’s still a wider choice of lenses available for DSLRs.
ALMOST all serious photographers prefer to use cameras with interchangeable lenses, as this gives the greatest degree of creative ﬂexibility. At one time, this meant digital single-lensreﬂex(DSLR) cameras, but these have now been joined by mirrorless compact System cameras (CSCs) that use electronic viewﬁnders. Previously, these lagged behind DSLRs in some respects such as autofocus. But the latest models have narrowed the gap considerably, and are true alternatives to DSLRs, offering the same image quality and creative options. Camera manufacturers offer a range of models, from simple, relatively inexpensive beginner-friendly designs through to sophisticated professional models.In The Middle Of The Range, you’ll ﬁnd enthusiast cameras with more advanced control layouts.
Interchangeable Lenses Come In a huge array of types for shooting different kinds of subjects for most enthusiast photographers, the easiest way to expand the kinds of pictures you can take is by buying different types of lenses. For example, telephoto lenses let you zoom in on distant subjects, while macro lenses allow you to focus on small subjects. Large-aperture lenses allow you to isolate subjects against blurred backgrounds or shoot in low light without having to raise the ISO too high. Meanwhile, all-in-one superzooms cover a wide range of subjects, but with lower optical quality.
Built-in Focus Motor
Most lenses now incorporate an internal motor to drive the autofocus, although some still drive from the camera body. DSLR lenses often use ultrasonic type motor for fast focusing, while those for mirrorless cameras tend to employ video-friendly stepper motors.
A thread at the front of the camera will have a diameter, in mm, which will allow you to attach a variety of filters or adapters to the lens. Maximum aperture wider apertures mean you can use faster, motion-stopping shutter speeds.
