How to buy a camera

Updated May 1, 2026 · 2 min read

Camera selection has become a question of system commitment more than body specs. Once you pick Sony, Canon, Nikon, or Fuji, you're committing to that lens ecosystem for the next decade. Body specs are secondary.

01

Sensor format

Full-frame for low-light + shallow DoF; APS-C for portability + reach; Micro Four Thirds for video. Medium format for studio.

What to aim for

Full-frame for hybrid pros, APS-C for everyday + travel, MFT only for video-first specialists.

02

Lens ecosystem

Number, quality, and price of lenses available for the mount.

What to aim for

Sony E and Canon RF have the broadest 2026 lineups. Nikon Z is catching up. L-Mount (Panasonic, Leica, Sigma) is interesting for video.

03

Autofocus

Subject recognition + tracking quality determines keeper rate, especially for sports / wildlife / kids / animals.

What to aim for

Sony Real-time Tracking, Canon Dual Pixel Intelligent AF, and Nikon's 3D Tracking are all flagship-tier in 2025-26.

04

Video specs

Codec (ProRes / H.265 / RAW), bit depth, max resolution + framerate, internal vs external recording.

What to aim for

4K 60p 10-bit minimum for hybrid use. RAW recording (internal or external) for film projects.

05

IBIS

In-body image stabilization — measured in stops of correction.

What to aim for

5+ stops modern standard. Critical for handheld video; nice for low-light stills.

06

Ergonomics + EVF

Holds the camera comfortably for long shoots; EVF resolution + refresh make tracking easier.

What to aim for

Try in-store. EVF 5.76M dot or higher on flagships; 3.69M on mid-range.

Pitfalls to avoid

  • Don't buy on megapixel count alone — bigger sensors with fewer pixels often beat smaller sensors with more.
  • Kit lenses are usually the worst lens you'll own — budget for at least one good prime.
  • Used flagships from 2-3 years ago often outperform new entry-level bodies; consider used for entry into a system.

Our sweet-spot pick

Sony α7C II ($2199) for full-frame travel, Fujifilm X100VI ($1599) for compact street, Canon EOS R7 ($1499) for APS-C wildlife/sports.
