When deciding between a full frame or APS-C camera, image quality is one of the most important factors to consider. Full-frame cameras have a larger sensor than APS-C cameras, which leads to some key differences in image quality.

Resolution and Detail

Full frame cameras typically have higher megapixel counts, often 20MP or more, compared to 16-24MP for most APS-C cameras. The larger sensor size also means larger pixels, which can capture more detail. This allows full-frame cameras to produce images with finer details, even when cropping or printing large sizes.

For landscape, portrait, or commercial photography, where high resolution and sharpness are critical, a full frame is probably your best choice. For most casual use, though, APS-C resolution is perfectly sufficient.

Low Light Performance

The larger sensor of a full-frame camera is able to capture more light, which gives it a one to two-stop advantage in low light. This means you can use a higher ISO setting and still get usable images. Or, you can use a lower ISO setting and faster shutter speed to get sharper images in low light.

If you frequently shoot indoors, at night, or in other dim conditions without a flash, a full frame is a great option. The improved low-light performance will allow you to get shots that may not be possible with an APS-C camera.

Depth of Field

The larger sensor of a full-frame camera also provides a shallower depth of field, which means you can achieve more background blur for professional-looking portraits and macro shots. An APS-C sensor will require a longer focal length and closer focusing distance to get the same field of view and level of background blur.

For advanced photographers looking for maximum control over depth of field, full frame is the way to go. For most casual and beginner photographers, the deeper depth of field of APS-C can actually be more forgiving and easier to work with.

In the end, both full frame and APS-C can produce amazing, professional-quality images. However, when comparing overall image quality, full-frame does have some inherent benefits. For your needs, determine which factors are most important to you, then choose a camera type accordingly.
