[開箱] SONY a6700

 預計拿來當望遠備機

快捷鍵還是比a7系列少蠻多的，握把也較不好握，滾輪位置也比較奇怪，不過就看實際使用囉

[Old Lens Real world Review] MINOLTA MD 35mm F1.8 +SONY a7 RV

 Usable for portrait at F1.8, sharp enough F2.8 and above

[開箱]天工TECHART LM-EA9

先別管這中國牌為什麼取名叫techart這種曖昧的名子，轉接環也是這種LM-EA9企圖與SONY LA-EA5產生混淆的感覺，不過應該乾脆取名叫LA-EM9更好(lens adapter-E mount to M mount)

直接講結論好了，如果對焦目標不是那麼大，很可能還是有一些誤差，眼控對焦準確度也會下降，因此如果是重要畫面建議還是放大一下再確認比較好，但至少大部分的畫面都是可接受的

對焦速度一定不會快到哪裡去，大概就跟MINOLA a807si差不多的感覺，或再慢一點，而整個鏡頭移動的對焦方式也等於說是多了接寫環，大部分的鏡頭都更有實用性，畢竟老鏡們大多放大倍率差

另外，竟然是用micro USB不是用type C是蠻奇怪的

幾天使用後發現另一個問題，切到手動對焦後會回到無限遠，所以要設一個快捷鍵為「停止┬對焦」，對好焦後按著調整光圈在按下快門，成功率會比用小光圈對焦高；所以除非都是光圈全開或縮2級內拍，不然其實實用性沒有想像中的高

Although the 85GDL has the best bokeh in other older reviews, it doesn't perform better compare to modern lenses.

MINOLTA 85mm G(D) Limited test on MINOLTA a7 limited and SONY a7RV
On SONY a7RV, F1.8-2.2 seems a good balance point. More detail, still good bokeh and less CA.
On film camera, F1.4 is usable.
