Full-Frame vs APS-C (2026) – Which Sensor Size is Right for You?
8 min read • Updated March 2026
Full-frame vs APS-C is one of the most common questions from photographers choosing their first serious camera. Both formats have distinct advantages, and the choice depends on your priorities and budget.
Sensor Size Explained
A full-frame sensor measures 36×24mm — the same size as 35mm film. An APS-C sensor is smaller, measuring approximately 23.5×15.6mm. This size difference affects image quality, depth of field, lens selection, and cost.
Full-Frame Advantages
Full-frame sensors offer superior low-light performance, shallower depth of field at equivalent focal lengths, and better dynamic range. They're the standard for professional photography and command a price premium both new and refurbished. Examples include the Canon EOS 5D Mark IV, Sony A7 III, and Nikon D850.
APS-C Advantages
APS-C cameras are significantly more affordable, more compact, and offer a 1.5x crop factor that effectively extends telephoto reach. For travel, wildlife on a budget, and hybrid shooting, APS-C is often the smarter choice. Popular APS-C options include the Sony A6400, Fujifilm X-T4, and Nikon D7500.
Refurbished Pricing
The refurbished market makes full-frame accessible. A used Canon 5D Mark III or Sony A7 II can be found for £400–£600, making the full-frame vs APS-C decision less about budget and more about your actual needs.
