In the case of mirrorless cameras and DSLRs, moving up to a more advanced camera from a beginner’s model can give you dedicated manual shooting controls, like a second contextual dial for independently setting shutter speed or aperture or ISO.
Dedicated exposure dials and quick-access buttons for important shooting controls like ISO are also more common in advanced cameras, as are customisable function buttons that can be mapped to certain more advanced features that you’re only likely to find in advanced cameras, like Wi-Fi photo sharing, live filters, or advanced HDR bracketing.
High-end mirrorless cameras like Sony’s a7 range, courtesy of their full frame image sensors, are perfectly suited to mounting older full frame prime lenses designed for high-end film cameras, as well as any existing full frame glass you might have from an old digital camera.
If you move up from a basic mirrorless camera to a high-end one, for example, you’ll find that you’ll get an imaging sensor far more capable at shooting clear and detailed pictures in low light, as well as in complex lighting situations like under tungsten street lights.
Only high-end cameras have the top-of-the-line full frame imaging sensors that are the best you’ll be able to buy in any consumer camera today.
More advanced cameras are able to capture burst-mode images at a higher frame rate — more photos per second — because they have more internal memory, better processing engines, and more robust shutter mechanisms.
More advanced DSLRs from Nikon are the only models in that company’s lineup to include internal screw-drive motors to automatically focus Nikon’s older DSLR lenses, where you’ll be left focusing manually on a cheaper model.
The big difference between a basic camera aimed at amateurs and occasional photographers and an advanced model for enthusiasts is that the high-end variant will always take better photos in a wider range of lighting and environmental conditions.
Better materials also play a larger part in taking lots of photos than you’d think — having a soft-touch rubberised or leatherette hand-grip might be the difference between holding onto your camera when you take a wrong step and it clattering to the ground and breaking.
In high-end cameras you get superior autofocus systems that can lock focus faster and in lower light, reducing the number of accidentally out-of-focus pictures that you’ll capture.
