The Nikon offers full HD video capabilities, including progressive frame rates conducive to smooth motion capture, albeit without in-body stabilization or audio inputs. The Olympus E-520 lacks video recording functionality altogether, reflecting its pre-hybrid era release timing.

For users who desire video versatility, the Nikon is unequivocally the superior and contemporary solution.

Build Quality and Weather Resistance

Neither camera boasts substantial environmental sealing, but construction quality influences durability.

• Nikon D3400 utilizes robust polycarbonate body panels over a magnesium alloy frame, balancing weight and resilience.
• Olympus E-520 is similarly constructed but is heavier and prone to feel less solid due to outdated design ethos.

Neither model is weather-sealed or ruggedized; care is advised for adverse conditions.

Lens Ecosystem and Compatibility

The choice and availability of compatible optics largely dictate a camera's creative flexibility.

• Nikon D3400 employs the venerable Nikon F-mount supporting over 300 lenses spanning multiple generations, including modern AF-S and DX lenses optimized for APS-C sensors. This provides vast options from affordable primes to high-end professional telephotos.
• Olympus E-520 uses the Four Thirds mount, which remains supported but notably smaller in optical variety (circa 45 lenses). Being a Four Thirds (not Micro Four Thirds) camera, it is incompatible with the latter's expansive mirrorless lens line without adapters, which introduce compromises.

Photographers seeking expansive glass choices and future-proofing will find the Nikon system more advantageous.
