This a blogger based in Hong Kong and has tested many lenses.
The original article link is at the top of the page. If you’re proficient in Cantonese, you can read the original post; there’s also a selection of multilingual translations. However, the blogger uses a lot of humor and slang, making it challenging to understand even for people studying the language. I’ve done my best to translate the core ideas and the test conclusions.
These replica lenses are notorious for sample‑to‑sample variation, so the results here may not apply to every copy. Reviewers should use their own discretion. All content in this translation remains the copyright of the original blog.
