Teleconverter supportCompatible with SEL14TC and SEL20TC; maximum magnification increases to 2.8× with SEL20TCNot compatible with Sony E-mount teleconverters
Focus and stabilisation
AutofocusYesYes
Minimum focus distance0.26 m0.57 m
Maximum magnification1.4×0.25×
Optical stabilisationYesYes
Autofocus detailFour XD linear motors with floating focus; Alpha 9 III up to 120 fps AF tracking and 4K 120p tracking depend on compatible body and shooting conditionsDirect-drive SSM; contrast and focal-plane phase-detection autofocus support depends on camera compatibility
Focus distance detailSliding focus ring selects FULL MF with distance and magnification scales; full-time DMF works even during AF-C; Linear Response MFMacro switching ring selects 0.85 m–infinity or 0.57–1.0 m ranges; main minimum uses close-focus range
Magnification detailMaximum native magnification 1.4× at 0.26 m minimum focus measured from the sensor plane; working distance from the hood is shorter0.14× in 0.85 m–infinity range; 0.25× in 0.57–1.0 m close-focus range; not a 1:1 macro lens
Stabilisation detailLens optical stabilisation compensates angular yaw/pitch, X/Y shift and front/back Z movement; Sony qualifies the new front/back correction for still photographs only and publishes no stop ratingBuilt-in Optical SteadyShot; can work with compatible five-axis camera body stabilisation; no maker stop rating published
Video features–Aperture click switch permits adjustment without click sound

Release detailSony announced on 30 September 2025. Sony Germany specified availability from late October 2025; UK and North American releases specified November 2025, and Japan specified 21 November 2025. Month precision records the earlier German window; no exact German first-sale day publishedSony US announcement dated 7 February 2017 specifies March shipping in North America; exact first global sale day unconfirmed. Two independent full reviews read: Photography Blog Mark Goldstein on Alpha 7R II and OpticalLimits Klaus Schroiff, whose stabilisation assessment also uses Alpha 7R II. Preserve their conflicting raw distortion, vignetting and autofocus findings. Neither review material claim used as maker fact: Blog describes aluminium, OpticalLimits high-quality plastic. Blog sliding-focus-ring description is inconsistent with maker AF/MF switch. Geometric F numbers retained in main aperture fields; transmission explicitly qualified; no inferred predecessor link
