CONTAX S2/Aria, YASHICA FX-3 Viewfinder Rubber Eyepiece Replacement 相機的眼罩代用品

2022.2.6

The original viewfinder rubber eyepiece model for YASHICA FX-3, CONTAX S2, and Aria is F-3. Since these cameras have been discontinued for many years, it's nearly impossible to find the original eyepiece on the internet. Of course, using the camera without the eyepiece is still possible. However, for photography enthusiasts who wear glasses, it can be inconvenient because the plastic frame of the viewfinder constantly hits the lenses of the glasses. This repeated contact may cause the coating on the lenses to peel off. Therefore, I believe installing a rubber eyepiece has its advantages, providing both light shielding and protection for glasses. Are there any non-original replacement options? Yes, let's try two non-original rubber eyepieces here.

After installation testing, the rubber eyepiece with the code EF (for EOS 450D/550D/600D/650D/700D) and EB (for EOS 60D/50D/5D2/40D/30D/20D/10D) from Canon EOS digital cameras fits perfectly.

YASHICA FX-3 、CONTAX S2及Aria的原廠觀景窗橡膠眼罩型號是F-3。由於這幾款相機已經停產多年，所以原廠眼罩在網路上幾乎是買不到了，當然沒有眼罩也是可以用啦。這對戴眼鏡的攝影同好來說倒是有些不便，因為觀景窗的塑膠外框會一直敲到眼鏡的鏡片，多敲幾次難免鏡片的鍍膜會脫落，所以我覺得裝個橡膠眼罩還是有好處，除了遮光還有保護眼鏡。那麼有沒有非原廠的替代品呢? 有的，這裡就讓我們來試試兩個非原廠的橡膠眼罩吧。

經過安裝測試，Canon EOS 數位相機的觀景窗橡膠眼罩編號 EF (EOS 450D/550D/600D/650D/700D 及 EB (EOS 60D/50D/5D2/40D/30D/20D/10D) 剛好可以適用。

Sony A7 II + Konica、Voigtlander L39 Lens Test 鏡頭測試

2021.8.24-26

Recently, I've collected three L39 lenses:

1. Konica Hexanon 35/2: Derived from Konica's fixed-focus automatic camera Hexar, this lens was limited to 1000 units in 1996. It features a 7-element, 6-group design, reportedly inspired by the Leica Summicron 35/2. It has a minimum focusing distance of 0.9 meters, aperture range from 2 to 16, and a 46mm filter thread. It comes with original lens hood and front/rear caps. The one I have is numbered "853."
2. Kinishiroku Hexar 50/3.5: This lens emulates the design of the Leitz Elmar 5cm f/3.5. It has a 4-element, 3-group Zess Tessar design, with a minimum focusing distance of 3.5 feet and aperture range from 3.5 to 22. It was first sold in 1955, paired with Japanese-made cameras mimicking the Leica III (L39) such as Chiyotax, Leotax, Nicca, etc.
3. Voigtlander Color-Heliar 75/2.5: Released in 1999, this is said to be the first 75mm lens with an L39 mount after World War II. It features a 6-element, 5-group design, with a minimum focusing distance of 3.5 feet or 1 meter, and aperture range from 2.5 to 16. It has a filter thread of 43mm.

最近收集了三顆L39鏡頭: 

1. Konica Hexanon 35/2 源自Konica的定焦自動相機Hexar的鏡頭，在1996年限量銷售1000顆，鏡組是7片6群的結構，據說是源自Leica Summicron 35/2的設計，最近對焦距離為0.9米，光圈為2~16，濾鏡口徑46mm，附有原廠遮光罩與鏡頭前後蓋，我手邊的這顆是編號"853"。
2. Kinishiroku Hexar 50/3.5 模仿 Leitz Elmar 5cm f/3.5 設計的鏡頭，鏡組同樣是是4片3群的Zess Tessar設計，最近對焦距離為3.5英呎，光圈為3.5~22，濾鏡口徑34.5mm。首次銷售是在1955年，搭載一樣是模仿Leica III (L39)相機的日本製相機，如Chiyotax、Leotax、Nicca等品牌。
3. Voigtlander Color-Heliar 75/2.5 1999年上市，據說是二次世界大戰後的第一顆L39接環的75mm鏡頭，鏡組是6片5群的結構，最近對焦距離為3.5英呎/1米，光圈為2.5~16，濾鏡口徑43mm。

The 1955 Kinishiroku Hexar 50/3.5 lens, paired with the 2015 Sony A7 II, demonstrates how the advent of full-frame mirrorless digital cameras has revived many vintage lenses in the digital imaging era. Additionally, it's suggested to consider versions of Leica L39 to Sony E mount adapters with close focusing functionality, allowing traditional rangefinder lenses with limited focusing to focus closer than 1 meter.

1955年的 Kinishiroku Hexar 50/3.5 老鏡搭上 2015年的 Sony A7 II，多虧全幅無反數位相機的問世，讓許多老鏡可以在數位影像時代重生。另外，也建議Leica L39 轉 Sony E接環的版本可以選購有微距條焦功能的版本，可讓傳統只能對焦到1米左右的測距相機鏡頭可以近拍到1米以內。

In late August 2021, as the first wave of the Covid-19 pandemic in Taipei gradually subsided, restrictions began to ease, and kids' soccer training resumed. During a few days when I had spare time while accompanying my child to classes at Da Jia Riverside Park, I took a stroll nearby with these three L39 lenses and the Sony A7 II camera, capturing some test shots.


2021年8月下旬，台北第一波Covid-19重大疫情逐漸消退，大家也開始解封，小孩的足球集訓也展開了。趁著幾天到大直迎風河濱公園陪小孩上課的空檔，我帶這這三顆L39鏡頭和Sony A7 II相機在附近逛了一圈，留下一些測試相片。
