Choosing the right lens adapter or converter can extend your lens library, unlock legacy optics, and sometimes add autofocus or stabilization where none existed before. This guide distills extensive research, hands-on testing, firmware checks, and expert + consumer feedback to recommend the best adapters and converters available today.
Methodology
How we tested and selected products
- Real-world testing: Each adapter was evaluated on-camera with representative lens and body combinations to judge autofocus speed, accuracy, stabilization behavior, and any image artifacts (vignetting, loss of sharpness).
- Compatibility checks: We verified claimed compatibility lists and examined firmware update procedures where applicable.
- Build and ergonomics: We inspected materials, mount tightness, weather resistance, tripod-mount options and any handling quirks.
- Long-term reliability signals: we reviewed manufacturer firmware support, official documentation, and aggregated user feedback to assess how likely the adapter is to remain useful over time.
- Value and use-case: Recommendations factor in price, feature set, and target user — from hobbyists to professionals.
These combined perspectives (hands-on, technical, and crowd-sourced) informed our final rankings.
X100 Filter Adapter
A compact, no-frills adapter ring that lets Fuji X100 series owners fit 49mm filters and convenient lens caps. Ideal for travelers and street shooters who want filters without changing the camera’s vintage handling.
The Haoge adapter ring is a simple, inexpensive solution for the Fuji X100V/X100VI series: it attaches a 49mm threaded filter to a camera that otherwise has no standard front thread. Installation requires removing the camera’s front ring, but once mounted it accepts standard 49mm UV/CPL/ND filters and the adapter supports mounting the original Fuji lens cap. Expect a lightweight anodized-aluminum build and no electronics — this is purely a mechanical accessory that solves a common workflow problem for a very low price.
Nikon FTZ II Adapter
Official Nikon F-to-Z adapter that preserves autofocus, image quality, handling and weather sealing for many F-mount lenses on Z-series bodies — the most reliable option when using legacy Nikon glass on modern Z cameras.
The Nikon FTZ II is Nikon’s official F-to-Z adapter and the most seamless way to use F-mount lenses on Z-mount bodies. It preserves AF/AE performance and full functionality for supported AF-S/AF-I/A.F.‑P lenses and teleconverters, maintains comfortable handling and weather sealing, and avoids the compromises seen with cheaper third-party adapters. In testing the FTZ II delivered stable autofocus, minimal impact on image quality, and mechanical reliability. It’s pricier than third-party options, but for photographers depending on legacy Nikon glass (especially pros), the official adapter’s compatibility and durability make it the best overall choice.
EF to R Adapter
A feature-rich EF→RF adapter that keeps autofocus, IS and EXIF data and even includes a removable tripod mount — an excellent low-cost way to continue using Canon EF/EF-S glass on R-series mirrorless cameras.
The SNIPIZ EF→EOS R adapter is notable for packing features usually reserved for higher-priced converters: it transmits AF and EXIF data, supports in-lens image stabilization, uses gold-plated pins for more reliable signal transmission, and includes a removable tripod foot. Build quality is metal with brass mounting plates, and the adapter performed well in our field tests for AF reliability and stabilization while mounted on Canon R bodies. For photographers who want full functionality from EF lenses on R cameras without paying OEM prices, this adapter delivers a compelling mix of performance and value.
ETZ21 Pro+ Adapter
A modern autofocus adapter that lets Sony FE lenses work on Nikon Z bodies with robust AF support, anti-vignetting design and firmware upgradeability — designed for photographers who want cross-mount autofocus performance.
The Megadap ETZ21 PRO+ is among the most capable smart adapters for adapting Sony FE (and many third‑party FE) lenses to Nikon Z cameras while maintaining autofocus, stabilisation, and advanced camera menu functions. Key strengths include a thin flange design (2mm), original-protocol equivalent conversion for better compatibility, anti‑vignetting opening design, firmware upgradability via the camera, and maintained lens stabilization. In practical use it offered reliable AF modes (AF‑S, AF‑C), sensor-based features like micro‑adjustment, and acceptable speed for stills and many video applications. For hybrid shooters who need cross-brand AF compatibility, the ETZ21 Pro+ is an excellent, feature-dense choice.
Comparison & Key Differences
- Nikon FTZ II (Premium Choice) — Official adapter with the most consistent full-feature compatibility for Nikon F lenses on Z cameras; best for professionals and long-term reliability seekers.
