Today, I took my CHINON 55mm f1.7 lens, which I've been collecting for years, out for the first time to shoot some flowers and plants. After attaching a 12mm extension tube and an adapter, I mounted it directly onto my Sony A7III digital camera. This setup basically turns it into a macro lens with a magnification of around 1:4 to 1:2.5. If I switch to APS-C mode, the magnification goes up to about 1:1.5, making it easy to capture close-up shots of the little yellow daisies (Wedelia) like the one shown here.
今天第一次帶著收藏多年的CHINON 55mm f1.7出門拍些花花草草，裝上12mm的延伸環和轉接環後直上Sony A7III數位相機，基本上就是約1:4~1:2.5的微距鏡頭了，如果再切換到APS-C模式，就是1:1.5左右的倍率，很容易就可以拍出以下小黃菊(蟛蜞菊, Wedelia)的近拍照。

I hadn't paid much attention to this lens before, mainly because I bought it along with the CHINON CM-3, an M42 film camera. Since CHINON was primarily an OEM for cameras and lenses, and its own brand was often associated with budget cameras and lenses, I didn’t particularly care about the optical quality of this lens. However, after recently researching this 55mm f1.7 lens online, I came across a claim that it was manufactured by the renowned Tomioka Optical. This piqued my interest, and I decided to give it a try.
以前沒有特別注意這顆鏡頭，主要是因為它是跟CHINON CM-3這台M42底片相機一起購入，由於CHINON本身是相機和鏡頭代工廠，自主品牌則常是廉價相機鏡頭的代表，我對這棵鏡頭的光學品質並未特別在意。前這子網路上查詢這顆鏡頭的資訊時，看到一種說法，即這顆55mm f1.7的鏡頭是有名的富岡光學代工，也就興起了試拍的念頭。

In June, before the peak of the hot summer, the pathway along the Sunshine Bridge in Xindian is lined with blooming little yellow daisies. The insects are also drawn to the flowers, lingering and flitting back and forth.
六月天，在進入炎熱的夏季前，新店陽光橋下的步道沿線都是盛開的小黃菊，蟲兒也受到了吸引，流連往返。
