GearScore™ Verdict — Which should you buy?

Everyday, Travel & Events On Fujifilm Or Sony Aps-C — 18-50mm f/2.8 DC DN Contemporary (2021): The lightest f/2.8 standard zoom ever made — 290g is astonishing for a lens of this capability, and it optically over-delivers at the price.

Travel, Portrait — A7 II (2014): The camera that proved full-frame IBIS was possible in a compact body.

A7 II (2014)

  • Photographers upgrading from APS-C who want full-frame on a budget
  • Film shooters adapting vintage lenses (IBIS helps enormously)

Quick take: The a7 ii is the most affordable; only the a7 ii is weather sealed. Scroll down for the full spec breakdown.
