Used-camera inspection

What to check before you pay

A clean, well-maintained older camera can be a better purchase than a newer body with hidden damage or an unclear history.

1

Shutter count

Use an original camera file whenever possible. Edited or exported images may no longer contain readable shutter metadata.

2

Sensor condition

Check for scratches, dust, hot pixels, banding, and unusual marks in evenly lit test images.

3

Autofocus and stabilization

Test multiple focus modes, subject detection, continuous autofocus, and IBIS with a known-good lens.

4

Card slots and ports

Confirm every card slot, USB port, HDMI port, microphone input, headphone output, and network connection.

5

Buttons and controls

Test every dial, joystick, button, touchscreen area, EVF sensor, and articulated-screen hinge.

6

Battery and accessories

Inspect the battery, charger, body cap, cables, strap mounts, and any included grips or adapters.

01

Estimated Shutter Life

Clear specification advantage

Moderate importance
Why this matters+

Technical impact

Estimated shutter life indicates how many mechanical actuations the shutter mechanism may be designed to tolerate before service becomes more likely.

What you may notice

Sony A7R VI carries the stronger estimated durability figure, which matters most to photographers who expect frequent mechanical-shutter use over many years.

Most relevant for

  • Wedding photographers

Buying advice

Favor Sony A7R VI when both cameras are similarly priced and you expect heavy long-term mechanical-shutter use.

Upgrade advice

A higher shutter-life estimate rarely justifies an upgrade by itself unless your current body already has very high usage or supports mission-critical paid work.

High importance
Why this matters+

Technical impact

Higher resolution provides more recorded detail and additional cropping flexibility, while also increasing file size, storage needs, and processing demands.

High importance
Why this matters+

Technical impact

Sensor format affects field of view, depth-of-field control, body and lens size, high-ISO potential, and the overall design of the camera system.

What you may notice

Both cameras use a comparable sensor format, so other performance differences should carry more weight.

Most relevant for

Buying advice

Sensor format does not meaningfully separate these cameras.

Upgrade advice

Changing sensor formats can be meaningful, but the cost of replacing or adapting lenses should be included in the decision.

Common misconception

A larger sensor is not automatically better for every buyer. Smaller formats can offer lighter lenses, lower prices, and useful effective reach.

Buying advice

Use measured performance and real shooting features instead of choosing solely from the sensor-technology name.

Upgrade advice

Sensor technology justifies an upgrade only when it produces a noticeable benefit such as faster readout, reduced rolling shutter, or better image quality.

Camera Type

No meaningful difference

Situational importance
Why this matters+

Technical impact

Camera type reflects the body design and intended workflow, such as mirrorless, DSLR, compact, cinema, or medium format.

What you may notice

The better format depends on handling preferences, lens ownership, viewfinder preference, and the work the camera must perform.

Most relevant for

  • System switchers
  • Professional specialists
  • Travel photographers
  • Video creators

Less important for

  • Buyers already committed to one format

Buying advice

Choose the body style that supports your lenses and workflow rather than treating camera type as a universal ranking.

Upgrade advice

Changing camera type is worthwhile when it solves a real workflow problem, not merely because one format is newer.

Lens Mount

Preference dependent

Critical importance
Why this matters+

Technical impact

The lens mount determines native lens compatibility, adapter options, system cost, and the long-term path available to the buyer.

What you may notice

Existing lenses can outweigh several body-level advantages because switching systems may cost far more than the camera itself.

Most relevant for

  • Owners of multiple lenses
  • Professional photographers
  • System switchers
  • Budget-conscious buyers

Less important for

  • First-time interchangeable-lens buyers
  • Buyers purchasing an entirely new system

Buying advice

Calculate the cost of the complete system—not only the camera body—before switching mounts.

Upgrade advice

A mount change should deliver a substantial workflow or lens benefit because switching costs can easily exceed the body-price difference.

Common misconception

A body that wins the specification comparison is not necessarily the better purchase if it requires replacing an entire lens kit.

One final consideration

The better camera on paper may not be the better camera for you.

These scores reward clear, measurable advantages. They cannot fully account for ergonomics, menu preferences, existing lenses, current used prices, physical condition, or how a camera feels in your hands.

Treat the verdict as informed buying guidance—not a replacement for handling the camera yourself or evaluating the complete cost of the system around it.

Before you decide

  • Handle both cameras if possible.
  • Compare the lenses you would actually buy.
  • Check current new and used prices.
  • Consider condition, warranty, and shutter count.
