Description

Lenses are divided into a number of groups with different AF capabilities. Contained within is a list of those capailities and the group that each lens belongs to.

Compatible Lenses and Autofocusing (Viewfinder Shooting)

Caution

  • Although the camera has 191 AF points, lenses are classified into 10 groups (A–J) which vary in the number of AF points available, AF point patterns, Area AF frame shapes, and other details.
  • When lenses in groups F–J are used, fewer AF points are available.
  • See Group Classification of Lenses for lenses you will use.

Note

  • AF points in positions indicated by [AF points sensitive to horizontal lines] blink when the AF point selection button is pressed (while [Dual cross-type AF point/Cross-type AF points/Cross-type AF points] points remain lit). For details on AF point blinking/illumination, see Meaning of Lit or Blinking AF Points.
  • For updates on “Group Classification of Lenses,” visit the Canon website or others.
  • Some lenses may not be available in certain countries or regions.

Group A

Autofocusing with 191 points is possible. All the AF area selection modes are available.

  • Dual cross-type AF point: Dual cross-type AF point. Offers superior subject tracking and higher focusing precision than other AF points.
  • Cross-type AF points Cross-type AF points: Cross-type AF point. Offers excellent subject tracking and high-precision focusing.
  • AF points sensitive to horizontal lines: AF points sensitive to horizontal lines.

Group B

Autofocusing with 191 points is possible. All the AF area selection modes are selectable.

  • Cross-type AF points Cross-type AF points: Cross-type AF point. Offers excellent subject tracking and high-precision focusing.
  • AF points sensitive to horizontal lines: AF points sensitive to horizontal lines.

Group C

Autofocusing with 191 points is possible. All the AF area selection modes are selectable.

  • Dual cross-type AF point: Dual cross-type AF point. Offers superior subject tracking and higher focusing precision than other AF points.
  • Cross-type AF points Cross-type AF points: Cross-type AF point. Offers excellent subject tracking and high-precision focusing.
  • AF points sensitive to horizontal lines: AF points sensitive to horizontal lines.

Group D

Autofocusing with 191 points is possible. All the AF area selection modes are selectable.

  • Cross-type AF points Cross-type AF points: Cross-type AF point. Offers excellent subject tracking and high-precision focusing.
  • AF points sensitive to horizontal lines: AF points sensitive to horizontal lines.

Group E

Autofocusing with 191 points is possible. All the AF area selection modes are selectable.

With an extender attached to extendable lenses, AF is available when maximum aperture is f/8 (in a range of f/5.6–f/8).

  • Cross-type AF points: Cross-type AF point. Offers excellent subject tracking and high-precision focusing.
  • AF points sensitive to horizontal lines: AF points sensitive to horizontal lines.

Caution

  • If the maximum aperture value is slower than f/5.6 (greater than f/5.6 but not exceeding f/8), focus may not be achieved with AF when shooting low-contrast or low-light subjects.
  • If the maximum aperture value is slower than f/8 (greater than f/8), AF is not possible during viewfinder shooting.

Group F

Not all 191 AF points can be used for autofocusing, but the 139 points shown here are available. All the AF area selection modes are selectable. During automatic AF point selection, the outer frame marking the AF area (Area AF frame) will be different from 191-point Automatic selection AF.

  • Cross-type AF points: Cross-type AF point. Offers excellent subject tracking and high-precision focusing.
  • AF points sensitive to horizontal lines: AF points sensitive to horizontal lines.
  • Disabled AF points (not displayed): Disabled AF points (not displayed).

Group G

Not all 191 AF points can be used for autofocusing, but the 87 points shown here are available. All the AF area selection modes are selectable. During automatic AF point selection, the outer frame marking the AF area (Area AF frame) will be different from 191-point Automatic selection AF.

  • Cross-type AF points: Cross-type AF point. Offers excellent subject tracking and high-precision focusing.
  • AF points sensitive to horizontal lines: AF points sensitive to horizontal lines.
  • Disabled AF points (not displayed): Disabled AF points (not displayed).

Group H

The 23 AF points shown here are available for autofocusing. As the AF area selection mode, choose from Spot AF, 1-point AF, Expand AF area: AF point expansion, Zone AF (manual selection), or 23-point Automatic selection AF.

With an extender attached to extendable lenses, AF is available when maximum aperture is f/8 (in a range of f/5.6–f/8).

  • Cross-type AF points: Cross-type AF point. Offers excellent subject tracking and high-precision focusing.
  • AF points sensitive to horizontal lines: AF points sensitive to horizontal lines (AF points left and right of the center) or vertical lines (AF points above and below the center).
  • Disabled AF points (not displayed): Disabled AF points (not displayed).

Caution

  • Expand AF area: AF point expansion applies to the 23 available AF points. Expansion for manually selected AF points that are not surrounded by active AF points is limited to any available adjacent points.
  • If the maximum aperture value is slower than f/5.6 (greater than f/5.6 but not exceeding f/8), focus may not be achieved with AF when shooting low-contrast or low-light subjects.
  • If the maximum aperture value is slower than f/8 (greater than f/8), AF is not possible during viewfinder shooting.

Group I

The 15 AF points shown here are available for autofocusing. As the AF area selection mode, choose from Spot AF, 1-point AF, Expand AF area: AF point expansion, or 15-point Automatic selection AF.

With an extender attached to extendable lenses, AF is available when maximum aperture is f/8 (in a range of f/5.6–f/8).

  • Cross-type AF points: Cross-type AF point. Offers excellent subject tracking and high-precision focusing.
  • AF points sensitive to horizontal lines: AF points sensitive to horizontal lines (AF points left and right of the center) or vertical lines (AF points above and below the center).
  • Disabled AF points (not displayed): Disabled AF points (not displayed).

Caution

  • AF point expansion (manual selection AF point expansion) applies to the 15 available AF points. Expansion for manually selected AF points that are not surrounded by active AF points is limited to any available adjacent points.
  • If the maximum aperture value is slower than f/5.6 (greater than f/5.6 but not exceeding f/8), focus may not be achieved with AF when shooting low-contrast or low-light subjects.
  • If the maximum aperture value is slower than f/8 (greater than f/8), AF is not possible during viewfinder shooting.

Group J

The 9 AF points shown here are available for autofocusing. As the AF area selection mode, choose from Spot AF, 1-point AF, or Expand AF area: AF point expansion.

  • Cross-type AF points: Cross-type AF point. Offers excellent subject tracking and high-precision focusing.
  • AF points sensitive to horizontal lines: AF points sensitive to horizontal lines (AF points to the left and right of the center) or vertical lines (AF points above and below the center). Manual selection is not available. Enabled only when Expand AF area: manual selection is selected.
  • Disabled AF points (not displayed): Disabled AF points (not displayed).

Caution

  • AF is not available with Extender EF 2x (I/II/III) attached to the EF 180mm f/3.5 L Macro USM lens.
  • Precise autofocusing may not be achieved if you use a lens and Extender EF1.4x III/EF2x III combination marked with an asterisk or a lens and extender in a combination marked with two asterisks. In this case, refer to the Instruction Manual of the lens or extender used.

Note

  • If you use a TS-E lens, manual focusing is required. TS-E lens group designations apply only when tilt or shift is not used.
