SUMMARY
Beginners often make predictable mistakes with their first prime lens, such as the 50mm f/1.8, mistaking technique issues for lens limitations. Common errors include constantly shooting at the widest aperture (f/1.8) without considering depth of field, leading to missed focus or soft images. Misunderstanding the crop factor on APS-C cameras can also lead to frustration with field of view. Instead of zooming with their feet, beginners may stand still, resulting in flat compositions. Fixating on bokeh over content and failing to stop down the aperture when needed are also frequent pitfalls.
TAKEAWAYS
Avoid shooting exclusively at f/1.8; stop down for greater depth of field when necessary.
Ensure focus is on the subject's eye, as shallow depth of field at f/1.8 makes focus critical.
Understand how crop factors affect the field of view of a 50mm lens on APS-C cameras.
Use prime lenses as an opportunity to 'zoom with your feet' and improve composition.
