Feature research

For 60 camera and lens pairs we went past “does it mount” and checked specific features against the manufacturer's manuals: autofocus, stabilization, burst rate, crop behavior, and aperture control.

60pairs checked

323findings, each with a source

12documented rules

How to read a finding

Supported: The manufacturer's documentation says the feature works under the stated conditions.
Limited: It works, but with a requirement or restriction you need to know about.
Unsupported: The documentation says it does not work.
Not verified: We could not find documentation that settles it either way. That is not the same as unsupported.

How the research was done

An AI research agent read the manufacturer's manuals, specification pages, and compatibility tables for each pair and recorded what they say, feature by feature. A second, independent AI pass reopened every cited page and checked that it supports the finding. A final review happened before publishing. Nobody has tested these pairs by hand, and no person has signed off on each finding, so treat them as a well-organized reading of the documentation rather than a lab result.

Some findings follow from a documented rule that covers a family of lenses. Each rule page shows exactly which pairs were checked under it. We do not stretch a rule to gear we have not looked at.

Canon EF lenses on EOS R bodies through the standard adapter

Sources checked 2026-09-07

Canon EOS R6 Mark IICanon EF 50mm f/1.8 STM

The standard adapter supports basic focus and aperture operation. Canon documents body IS and conditional maximum-burst eligibility; this lens has a specific E-TTL Auto ISO ceiling limitation.

6 findings →Canon EOS R6 Mark IICanon EF 24-70mm f/2.8L II USM

The adapted zoom supports camera focus and aperture control and appears in Canon's maximum-speed lens table. Zoom or focus changes during electronic bursts can lower the nominal rate.

5 findings →Canon EOS R8Canon EF 70-200mm f/2.8L IS III USM

The standard adapter retains this lens's autofocus and optical IS. The R8 has no sensor-shift IS; its electronic 40 fps and EFCS 6 fps maxima are conditional.

5 findings →Canon EOS RPCanon EF 50mm f/1.8 STM

The RP accepts this EF lens through the standard adapter and supports basic autofocus and sensor metering. Its body has no sensor-shift IS; lens-specific burst and stabilization performance remain unresolved.

5 findings →Canon EOS R5 Mark IICanon EF 70-200mm f/2.8L IS III USM

The adapted lens retains focus and optical IS, and the R5 Mark II manual documents combining camera and lens stabilization. Exact-table burst eligibility does not guarantee sustained 30 fps during focus or zoom changes.

Canon EOS 90DCanon EF-S 10-18mm f/4.5-5.6 IS STM

Native APS-C ultra-wide pairing with separate viewfinder and Live View AF choices, camera aperture control and switch-enabled optical IS.

6 findings →Canon EOS 90DCanon EF-S 18-135mm f/3.5-5.6 IS USM

Native APS-C zoom with ordinary optical IS; the special Panning scene feature is explicitly tied to lens firmware 2.0.0.

6 findings →Canon EOS 90DCanon EF 50mm f/1.8 STM

The EF 50mm mounts natively and gives approximately 80mm equivalent framing on the 90D; electronic manual focus requires camera power.

6 findings →Canon EOS 5D Mark IVCanon EF 24-70mm f/2.8L II USM

Native full-frame zoom with camera aperture control; Canon explicitly lists this exact lens for all 61 viewfinder AF points.

6 findings →Canon EOS 5D Mark IVCanon EF 70-200mm f/2.8L IS III USM

Native full-frame telephoto zoom with optical IS modes for still subjects and panning. Exact usable viewfinder AF-point coverage remains unresolved.

Canon EOS R7: five native lens configurations

Sources checked 2026-09-07

Canon EOS R7Canon RF-S 18-150mm F3.5-6.3 IS STM

APS-C travel zoom with camera-controlled stabilization; its closest focusing region requires MF.

6 findings →Canon EOS R7Canon RF-S 18-45mm F4.5-6.3 IS STM

Compact APS-C zoom; extend it before shooting and leave the MF-only region before returning to AF.

5 findings →Canon EOS R7Canon RF 50mm F1.8 STM

Full-frame RF prime usable on the R7 with body stabilization; its FOCUS/CONTROL switch does not select AF/MF.

5 findings →Canon EOS R7Canon RF 24-105mm F4L IS USM

Separate lens switches govern AF and stabilization. Newer firmware enables the documented full-time manual-focus feature.

5 findings →Canon EOS R7Canon RF 100-400mm F5.6-8 IS USM

RF telephoto zoom with lens-controlled AF and combined stabilization; menu behavior depends on those physical switches.

Compact Fujifilm kits: aperture controls, stabilization and firmware exceptions

Sources checked 2026-09-07

Fujifilm X-M5Fujifilm XC15-45mmF3.5-5.6 OIS PZ

A native power zoom with menu-controlled aperture and OIS. Lens firmware 1.12 addresses the documented X-M5 retract/reinitialize problem.

5 findings →Fujifilm X-T30 IIFujifilm XC15-45mmF3.5-5.6 OIS PZ

The zoom provides OIS and camera-dial aperture control. The TG-BT1 grip can connect at the documented camera version, but its T/W buttons are explicitly excluded for X-T30 II.

5 findings →Fujifilm X-T30 IIIFujifilm XF27mmF2.8 R WR

The R WR pancake fits directly and adds a physical aperture ring. Movie Optimized Control changes that ring’s behavior; the lens distance readout remains approximate.

4 findings →Fujifilm X-Pro3Fujifilm XF27mmF2.8 R WR

A native compact prime with an aperture ring and manual focusing from the body selector. Focus-distance numbers are approximate rather than a measuring instrument.

4 findings →Fujifilm X-T4Fujifilm XF27mmF2.8 R WR

The native pancake works with X-T4 aperture controls and the body’s movie stabilization system. Digital stabilization has a specific high-speed Full HD exclusion.

Fujifilm X-T5Fujifilm XF18-55mmF2.8-4 R LM OIS

The native zoom has lens switches for OIS and aperture mode. Check its firmware before diagnosing shutter-dependent softness.

4 findings →Fujifilm X-T5Fujifilm XF33mmF1.4 R LM WR

This prime uses X-T5’s in-body stabilization. Its aperture ring locks at A, and the on-screen distance is only a guide.

4 findings →Fujifilm X-H2Fujifilm XF16-80mmF4 R OIS WR

OIS is controlled in the camera menu, and the lens manual recommends leaving it enabled even on a tripod. X-H2 firmware 5.20 adds a useful manual-focus control.

4 findings →Fujifilm X-H2Fujifilm XF16-55mmF2.8 R LM WR II

The second-generation zoom has an aperture click switch. Smoother movie exposure tracking has an exact X-H2 firmware and settings qualification.

5 findings →Fujifilm X-S20Fujifilm XC15-45mmF3.5-5.6 OIS PZ

This compact power zoom uses the camera menu for OIS and a command dial for aperture. X-S20’s +MOTION option depends on exposure settings.

6 findings →Nikon D850Nikon AF NIKKOR 50mm f/1.8D

AF Nikkor 50mm f/1.8D supports ordinary D850 autofocus and FX capture, but it does not qualify for automated focus shift. Camera-dial aperture control requires its ring locked at f/22.

6 findings →Nikon D850Nikon AF-P DX NIKKOR 70-300mm f/4.5-6.3G ED VR

This AF-P DX VR zoom supports D850 autofocus, camera-menu optical VR and focus shift. DX stills preserve its intended coverage; manual focus needs the camera awake.

The updated lens is eligible for the a9 III’s highest AF/AE burst tier, with settings and aperture limits.

4 findings →Sony a9 IIISony FE 24-70mm F2.8 GM II

Lens firmware 02 enables the documented 120 fps AF/AE tier; native compatibility alone does not establish that update is installed.

4 findings →Sony a1 IISony FE 70-200mm F2.8 GM OSS II

This exact second-generation zoom is in the a1 II’s 30 fps AF-tracking table; RAW type and aperture-drive settings change the result.
