Only update since my last post is Ronit's.You got the lenses right.
Macro is only a 2MP lens, and focal distance is like 4cm.
Can give interesting results when there's lot of light, but you're right that zoom x2 usually gives better results.
I'll try to post some XML here and there but cannot send all updates. Especially Ronit's are updated almost daily
I'm sharing the 2 versions.
+ Fast Processing
- Can Be Noisy (Can Produce Better Details With Gd Lighting)
+ Noise Reduction (Smoother Image Outputs In Low light)
- Slow Processing
Both with MIUI and OSS version.
