v2.1
7e54d60

LUT/DCP importer for Sony A7C II / ILCE-7CM2 firmware 2.01. No AI or prior FL23 installation is required.

  • lut.py: single-file Python CLI. Setup · File-to-camera guide.
  • a7c2-tools-2.1.zip: complete source, English/Simplified Chinese guides and the existing FL23 Windows CLI/desktop entry.
  • a7c2-dcp-profiles-2026-10-18.zip: 18 unchanged original DCPs, including Astia, with original attribution/notices.
  • SHA256SUMS.txt: download checksums.

This build fixes normal-USB body binding, recognized busy/no-card service acquisition and false installation failures caused by unrelated runtime fields. It keeps complete backups, exact program fingerprints/readbacks, writable AP-setting preservation and four protected CP units. FL23 code is unchanged by this update.

On one Windows camera with an existing six-look installation, slot 5 was imported from the Ricoh GR Positive Film DCP. The exact packaged lut.py then imported Astia into slot 4 using import --write. Both jobs passed duplicate backups, preflight, actual writes, full readbacks, cold-load, owner preview/photo acceptance and standalone reload verification to COMPLETE. Other slots and FL2/FL3 were preserved. Software checks: 82 LUT, 8 FL23 and 37 host tests. Evidence and limits.

Validation scope: stock first-install, physical Mac USB and this job's physical restoration remain untested. Color conversion uses a shared one-scene approximation, not the complete Adobe renderer or exact Fuji/Ricoh matching. This is not a Sony-signed firmware update. main now contains both FL23 and LUT/DCP, with separate user guides and AI reproduction guides.

用于 Sony A7C II／ILCE-7CM2 固件 2.01 的 LUT／DCP 导入器，不依赖 AI，也不必先安装 FL23。

单独使用 LUT，下载 lut.py 即可：安装依赖 → 从文件到相机的八步教程。完整工具包另含源码、中英文说明及原 FL23 Windows 命令行／桌面入口；独立 DCP 包包含 Astia 在内的 18 个原始文件和原署名／许可；校验值见 SHA256SUMS.txt。

本版修复普通 USB 机身绑定、已知忙碌／无卡服务连接，以及无关运行字段误拦截。保留完整备份、精确程序指纹／读回、可写 AP 设置及四个受保护 CP 单元核对；未改动 FL23 代码。

已在一台 Windows 相机的既有六款版本上导入第 5 槽理光 GR 正片，再使用发布附件同一份 lut.py，以 import --write 导入第 4 槽 Astia。两次均通过双份备份、只校验、真实写入、完整读回、冷启动、机主预览／拍照验收及单文件重载核对，达到 COMPLETE；其他槽位和 FL2／FL3 保留。通过 82 项 LUT、8 项 FL23、37 项主机测试。原厂首次导入、Mac USB 和实机还原仍未验证。默认色彩映射为单场景近似，不是完整 Adobe 渲染或富士／理光精确复刻，也不是 Sony 签名固件。

main 已包含 FL23 和 LUT／DCP 两个独立入口，并分别提供用户及 AI 复现说明。下载 DCP 不会自动写入相机，请按教程操作。

Version 2.1 packages the tested preview implementation with updated main-branch documentation and download links; only the CLI version string changed in executable source. FL23-only users can continue using v1.0.

v2.1 将已实测的预览版实现与最新 main 文档／下载链接统一打包；可执行源码仅改变版本字符串。只使用 FL23 的用户仍可下载 v1.0。
