1. 首先，聲明一下，我並唔賣鏡，亦無同間廠有任何利益或非利益關係，只係間廠嘅深圳專櫃同我返工嘅地方好近啫。
2. 支鏡就泥有貨，約HK$140 or 人仔 120 到，約貴咗HK$20。
3. 間鏡廠仲係度，只係鏡片舊電鍍廠倒閉，新嘅鏡要June 18 2010先有貨，聽講好D，我準備再買，唔知住。
4. 聽講有店係無貨期間炒到HK$ 1K，唔好中招，間厰嘅專櫃係我公司附近，根本人哋日日都係度。
5. 若果唔想返大陸買，可以到下面連結買，但比較貴，唔係廠家嘅Taobao店，但我覺得價錢OK，有RJ 接環同 25/1.4。

6. 同廠家講過，叫佢哋開Taobao 店，但佢哋無乜經驗，所以我估上面係最平。

2. I went to the shop on Dec 11 2009.  The latest 35/1.7 seems does not require to mod anymore, as they use a shorter black ring.

大家攪團購小心dd.  睇清圖片. 唔好攪錯鏡. 因為大部份cctv後成像圈太細, 根本連1x1都唔得.

ShiuFai - 枝鏡的黑環，高約6.8mm, 磨到6.4mm左右就停，focus 到500-600呎都無問題，如有需要便再磨多少少，相信磨到6.２mm左右就可以， 可能同我個mount 有關 (SSP C mount 兩用，送個好似是L39輔加環，朋友代買不清楚），但我建議各位師兄分幾次磨低．

Dec 02 2009 Updated:  
Ching -  NunChuk mentioned that regular C->m4/3 mount is not fit for this lens,  suggested us to go with RJ mount.

1. 放假加咗相. 原來支鏡有d轉. 有d相只是用作散景參考. 有張是故意連塵影埋。
2. RJ Mount SSP 螢X賣hk$270咋!
3. RJ mount 個樣及37.2mm 請看 #72嗰回複. VW1968有圖比大家睇.
4. Some one using this for grinding. http://www.omuser.com/viewthread.php?tid=104513&extra=page%3D1
5. 我用磨刀石, 有人用模型車床, 雷射切割, 60号水磨沙紙(用膠紙貼好並露出要磨部份).

Original =========================================================================================
Even if you don't mod, it still works for 1-2.0 meters distance for focus.
The place to get this lens is the same as CCTV Lens 25/1.4, so, I don't post the address again.
Please refer to http://www.dchome.net/viewthread.php?tid=789736&extra=page%3D1 for detail on location and contact.

first step: making use a WIDE cut C-mount to m4/3 which is 37.2mm as below link

http://auction1.taobao.com/aucti ... 4971251a1a&xID=0db2



Then, just unscrew the 3 screws at the buttom and rotate the black ring out and grind about 1 to 1.5mm on that ring, put it back on, then, it is OK.  If you sand too much, it will over infinity.  so better test and try.










佢細Range幾合用. 由20-40mm呢個 Range都好合m4/3 做Snapshot.

我支持新手平平地買支, 學下用手動鏡, 用熟發覺中意先至搵貴價手動鏡
但不要買多

Yeap!  just to share.  no connection with the company.

嘩好正呀lee支d 色
真係要諗辦法買支先得

Very good.

Thanks for the sharing

好精彩但唔識改

ruy ching,

D相效果真係好得, 小弟都想買番支.

可否告知磨短黑環的長度和用什麼方法切短, 萬分感激.

尼支都算睇SAMPLES好好的一支

I think I'll go there to get one later this week after I got my EVF, any one interested?

I am interest, please pm me if u would give me a help. Thanks

唔記得講呢支係全無黒角, 記得睇吓個環條link, 有冇37.2mm, 如果係團購嗰個百幾蚊環我唔知得唔.
影完第一批相自己都唔信, 小心影人會太利, 我用磨刀石打圏磨, 有朋友用粗沙紙, 另一個朋友用做模型車床, 我用人手高速磨咗二十分鐘到. absolutely better than Pentax 25/1.4 a lot for sure.

Ching,

Nice pic. I am very interested in it.

Any photo after mounting the lens to GF1?

How much for the mount and where to buy it?

Does it support AF?

It is slightly larger than the 5 HK$ in diameter.  the length is slightly longer than the pancake 20/1.7.  I am office now cannot show you the photo in the morning.  maybe tonite

and of course.  it is a manual lens,  definitely no AF.  

The adapter is on the link on my first message, you can figure it out and know where to get it.  Don't go with the group purpose mount, coz.  I am rather sure it is smaller than 37.2mm.

好介紹呀
平平地當玩具
今日上開去買番支先

oh,  very very nice  !!!!!!

Thanks for Ruy's info. and just got the lens, need to wait for the adaptor and then make the modification.

For those who want to buy the lens, if you have a friend who works in China (GD area), just give a call the the shop and ask them to deliver the lens locally, the lens can be arrived in 1-2 days, they accept 貨到付款, no need to go to shop individually as the transportation costs nearly half the prices of the lens.

會唔會有人攪團購呢?

我支都未改，今晚返去試下跟住改先

Penny: 陳生from Pumb said, he achieve infinity after he grind 1mm.  so, you should try 1 mm, but when you put it back on the lens, don't screw too hard, as it will jam the aperture ring.
