With 35mm film this requires a magnification ratio of only approximately 1:4, which demands less of lens quality than 1:1.

Other factors impact a sensor's resolution, including sensor size and lens quality.

The resolution that one can achieve in practice using these image-based techniques depends on a number of factors, including but not limited to camera resolution, lens optical quality, and marker size and quality.

Look at the lens quality, battery power and type of memory cards the different cameras use.

Great refractors were admired for their quality, durability, and usefulness which correlated to features such as lens quality, mount quality, aperture, and also length.

Unfortunately they are no longer produced but are to be found in specialist used-camera stores, and their lens quality is often superior.

While auto-programmes for every occasion have become standard issue on compact dials over the years (eg night-time, sport, landscape, portrait), manual control isn't something you'd expect from a budget model, nor is lens quality.

Finally, keep an eye out for lens quality.

Three quantitative measures were used: lens quality, exposure accuracy and speed of use.

Though these cameras are digital, lens quality still counts.
