Single-lens reflex (SLR) - is a type of camera that uses a movable mirror placed between the lens to show the image that will be captured in a viewfinder.
Digital single-lens reflex camera (digital SLR or DSLR) - is a digital camera that operates on the same optical and mechanical principles as a film single-lens reflex camera.
Exposure compensation - is a technique to compensate a measured exposure level against other factors which may render a less-optimal image (filters, non-standard processing, or intended under or overexposure).
Focal length - is a measure of how strongly it focuses or diverges light.
Telephoto lens - is a specific construction of a long focal length photographic lens that places its optical centre outside of its physical construction, such that the entire lens assembly is between the optical centre and the focal plane.
Wide-angle lens - is a lens whose focal length is substantially shorter than the focal length of a normal lens for the image size produced by the camera.
Normal lens - is a lens that generates images that are generally held to have a “natural” perspective compared with lenses with longer or shorter focal lengths.
F-number - is the quantitative measure of lens speed, in other words, the diameter of the entrance pupil in terms of the effective focal length of the lens.
Angle of view (Field of view) - describes the vertical and horizontal extent of a given scene that is imaged by a camera.
Viewfinder - is what the photographer looks through to compose, and in many cases to focus, the picture.

[...] This is a SLR (Single Lens Reflex) Camera on 35mm Film with Interchangeable Lenses. This model started to go on sale in 2004. It works in Autofocus and Manual Focus Mode with Focus Lock (Wide focus area, any local focus area can be selected from the 9-point sensors). Includes a few automatic Shooting Modes: Landscape, Macro, Night, Sports and Portrait. Combining the best of established 35mm system photography with digital photography affords photographers the ability to more fully express themselves. As the Anti-Shake function is built into the camera body and not the lens, it is effective for the entire range of Minolta AF lenses. Same as other cameras, supports Full-auto, Programmed AE (P mode), Aperture Priority (A mode), Shutter Priority (S mode), Manual (M mode) and 3 Custom modes. Also, it has self-timer: electronic with 10-second delay, cancelable or 2-second delay, 2 or more exposures in multiple mode. This model’s luxury is the depth-of-field preview and let’s not forget that it stores photographic data of up to 7 rolls of 36-exposure film (and for every frame these options: aperture, shutter speed, lens focal length, lens maximum aperture, exposure mode, metering mode, date/time information, exposure compensation, exposure bracketing values, flash compensation, flash bracketing values) . The common data panel on the top-plate is, in this case, quite small and shows only the shutter speed and frame counter. The data panel on the camera back shows the value of every single control on the camera. Technical Data: Metering: Ambient, Center-weighted Average, Spot metering, Flash metering or TTL Average Battery Type: 2 x 3V Lithium Battery (CR-2) Shutter Speed: 30 - 1/8000 sec Viewfinder Frame Coverage 90 % Viewfinder Magnification 0.7X ISO Range - Automatic Setting ISO 5,000 - 25 ISO Range - Manual Setting ISO 6,400 – 6 ISO Range - With flash: ISO 1000-25 Exposure Compensation: +/- 3 EV in 1/2 EV increments Flash sync: 1/200 s [...]
