自從上自寫email到Sigma請求他們考慮發展 4/3接環的SLR
內容大概是我多愛X3的畫質，也有　4/3 接環的 Sigma鏡頭及 Contax手動鏡，但實在無力同時擁有兩個系統，請他們考慮發展4/3接環的SLR　。

之前大都是客客氣氣的回絕，今天又收到自Sigma的回信，內容如下：
"Dear weikuang

Thank you very much for your message.
Around the mount part of the lens the camera there may not be enough space to add a mechanism that you have offered in your message. However, thank you very much for your suggestion, we have already forwarded it to our R&D team.

Kind Regards,
Vuslat Tatar

不知是我想歪了，只是單純的社交言詞，還是Sigma真的有將 4/3接環的DSLR列入考慮？如果真的有將此構想交付 R&D，各位如果期待Sigma出 4/3接環DSLR，就多多寫信製造輿論的壓力，也許夢想就成真了
