Subject: Digiscoping with the Canon G10 [Print This Page]

Author: fneil Time: 3/05/2009 08:01 Subject: Digiscoping with the Canon G10

I've been wanting to get my hands on the G10 to try digiscoping with it for some time as I know it's a great camera ( I have the G6). I bought one on Friday and tested it with various eyepieces - Swarovski 30x, Televue 32 mm Plossl, Televue 12mm Radian, Kowa 27x LER and Kowa 25x LER . The only eyepieces that gave good , unvignetted views were the Kowas. The G10 needs a lot of Eye Relief which the Kowas have. I have to use a balance bar to be able to slide the camera in and out as I zoom the lens .Here are some tests with the camera at home and out in the field.

Hi Neil,

I bought a G10 few days ago, I tried to used it with my STS80HD with 30x eyepiece. But the result is horrible.
I read your post mentioned about Kowa 25x LER with the STS80HD and work well.

May I have some question on it?
1) Can Kowa 25x LER connect to STS80HD directly?
2) Can you take a picture of this setting?

Thanks
Dick

Hi Neil,

I read your thread on birdforum, how can you do this with SWA 30x + DCA + G10????

http://www.birdforum.net/showthread.php?t=140498

and I search your flickr, is it a direct connect between STS80HD and 25x LER?

I am interesed in the G10 bcoz I can also go underwater shooting with its Cannon underwater housing at an affordable price, rather cost effective in that sense.

Sorry I didn't reply earlier. I'm glad you've sorted out the connection with the DCB. Nice photos, particularly the night heron.
The Canon adapter comes in two pieces. I just use the first piece and screw to the screw thread on the Kowa eyepiece using stepup/stepdown rings.
I don't zoom the camera lens much as vignetting will come in.

想問一下, 我還是想用DSLR來digiscope, 以你所講的3x-5x的倍率, 那麼我是否應該配一個105mm-175mm (35mm x3/35mm x5)的定焦鏡頭來做到洪兄所說的setting? 若果只用50mm標準鏡, 就失去了3-5倍率吧?!

我跟洪董先生的測試都是指在 DC for digiscoping 的情況下 , 我不清楚 DSLR+望遠鏡筒的應用 ... , 我看人家用 DSLR 好像都是直接接望遠鏡目鏡 , 中間沒有 DSLR 定焦鏡頭 ....

唔該dick兄, 這幅相雖然不算是佳作, 但以咁多限制黎講, 都已經可以收貨 (我想1200mm都影唔到這樣的效果吧?) 至少我都會滿意.

如果像papago兄這樣setup digiscope, 應該DSLR都無問題, 但係鳥屋震呢個真係惡搞o的, 但係個個都有呢個問題, 都算扯平吧?!

KOWA有自己的universal mount system, 有圖睇個setup係點樣, 好似幾可靠, 佢係專門設計俾人駁DV, DSLR, 而且有幾款不同的convertor同唔同diameter的adaptor ring, 好似幾handy喎.

Robbin, my apology if you think it's patronizing.  I don't have any relationship with anything about KOWA.  So NOT an ADVERTISEMENT or BOOST.

I'm concerned with this brand because I want to setup digiscoping as well.  After many comments and setup pictures of other experienced, I've found out that many brands, even SwaXXvski, have insufficient accessories to reduce vibration when taking images.  I find the setup by KXXa (I'd better mask some of it otherwise your comment is again 'stop patronizing, dude') is more easy and handy.  That's my comment.  NOT hard sell.

I've asked papago about this brand too since he has mentioned about his digiscope setup at the other thread.  I also thought about having the same setup like papago but the brand he mentioned was never seen in HK (at least I haven't seen it so far).  That's why I think about other brands.

I doubt whether we should mask all the brand names when talking about photographing stuff and be cautious in comments when we think a particular brand behaves/feels better as you have SO MUCH CONCERN about it?

I thk the Zexxx、Nikon (certain models)、Leica bla bla bla ....are also good scopes for digiscoping.

I have seen reviews and presentations on utube about those scopes, U may want to check them out.

個人愚見, G10雖然是一部好相機, 但G10 並不太適合用在digiscoping上
因為如果G10 zoom , 會出現好大個"黑圈"

我的setting 是 DCB + G10, 把G10 wide到28mm, 將鏡頭差不多貼住eyepiece,
如果eyepiece 是20-60x, 最好不要買G10, 可見我上面"荷花"的效果 (reply #19), 如果eyepiece是30x prime, 都可以勉強把它變成 30 * 28 的長鏡用

講真, 我個目鏡就是20x-60x. 在這情況, 唯有另找DC。各位ching, 有沒有好介紹?

現在我有一部Panasonic DMC-FX580, 當然它不是一個好選擇, 只不過是之前用開。經個人測試後, 發現在30x時、DC不zoom及主體夠大, 它才能用近拍設定後正確對焦。想知, 是不是用Macro對焦先至好?

為什麼會是夢幻機種，反mon有什麼關系？

Author: papago Time: 21/08/2009 22:21

根據我的經驗 , digiscoping 使用的 dc 最好有下列特性

1.電子快門線 , 更能防微震 ; 還有, 使用機械快門線 - 拆裝電池記憶卡不方便 , 電子快門線不會妨礙電池與記憶卡拆裝 , 但機械快門線(座)會 (我遇過幾次拍鳥中突然沒電 , 為了換電池還得連機械快門座拆下來才能換電池 , 真是急死人了 ...)
2.翻轉螢幕 , 因 LCD 在室外觀測易反光 , 可調整角度的 LCD 較易於調整到減少反光角度 , 另外超低角度拍水鳥 , 人也不用跟著趴下去 , 有了翻轉螢幕也比較不用 CARE 所使用的單筒是直筒還是斜筒 , 低角度拍水鳥請參考
3.光學倍率約 3X - 5X (台灣單筒達人洪董建議)
4.高階機種畫質
5.digiscoping 罩門就是快門速度低 , 聽說 G11 已加強快門可達 1/2000 , 高 ISA 畫質也比 G10 改進
6.至於 Dick 兄所述 G10 接單筒會有黑圈 , 我目前是認為應該跟套筒及目鏡口徑或單筒廠牌有關 , 也許我的 kamakura 83ed 不會有

, 等我買了 G11 再跟各位報告

其實還有一項 , 但我一直沒機會試試 RICOH 品牌 , 前四項功能目前 RICOH GX 系列都有 , 但 RICOH GX 系列還多了電子觀景器 , 其它廠牌還沒看到有此配備 , 我認為 "Digiscoping + 電子觀景器" 對拍飛行中的鳥會更容易 , 但這只是臆測 , 臆測原理為 : DSLR 系統中 , Canon 50D 可跟 DC 一樣 LIVE VIEW 拍攝 , 但我們可以想像 , 透過 LIVE VIEW 拍飛行中的鳥比較容易 ? 還是透過傳統方式 - 眼睛貼到光學觀景窗拍飛行中的鳥比較容易 ? 這就是我臆測所根據的原理 , 若有人使用過 RICOH GX 系列接單筒並有使用電子觀景器 , 可以分享一下心得

加上電子觀景器的 RICOH GX 系列

我部 Olympus C7070 都可以反 mon 架，不過無快門線

Author: thinfor Time: 21/08/2009 23:45

Papago兄, 你是指Canon EOS 50D抑或500D? 我現在用500D, 有live view function, 但對焦很慢(要長按鈕直至對焦準確的時間遠比按shutter拍照長得多), 原因live view function其實是用來拍video, 所以對焦的方法不像拍照的方法那樣靈敏. 但我認為都有優勢, 因為無論如何digiscoping手動對焦是無可避免吧?

另外電子快門線相信G11不可能沒有吧, 舊的機種都支援...唔, 我相信G11可以有raw format儲存吧?

有使用機械快門線嗎 ? 有無使用快門線拍鳥(尤其是 digiscoping 這種 "長焦低快門" 的系統) , 畫質會差很多喔 ...

50D 也有 LIVE VIEW , 其實我的 40D 就有 "半套" LIVE VIEW 了 , 只是從來沒用過
(40D 使用LIVE VIEW 後只能手動對焦 , 所以我稱它只有 "半套" LIVE VIEW ; 50D 是 "全套" LIVE VIEW - 使用或不使用 LIVE VIEW 都可自動對焦)
OLYMPUS E 系列 DSLR 很早就有 LIVE VIEW , 但我相信牠的 LIVE VIEW 不是用來拍動態影像(VIDEO)的 , 因為 OLYMPUS DSLR 不能拍動態影像

(新機種我就不曉得了)  , 早期 E 系列上的 LIVE VIEW 只是為了把 DSLR 做的像 DC 的拍攝方式 (很多 DSLR 初學者喜歡這樣)

至於您說的 , digiscoping 不管怎麼拍都是要手動對焦, 沒錯 , 但我是說接上電子觀景窗 , 或許會 "更容易" 拍飛行中的鳥 , 但當然仍不可能跟 DSLR 自動對焦那樣拍法
1.DSLR 上也是有很多手動鏡 , 我認識有人用萊卡手動鏡追拍飛行版 , 這跟 digiscoping+電子觀景窗+手動對焦有更類似的操作
2.手動鏡拍飛行版其實有個技巧 , 那就是打開連拍功能 , 拍攝中不停手動調焦 , 連拍時間長的話 , 應該會中一兩張清晰的 , 但 digiscoping 若沒有電子觀景窗 , 不要說拍了 , 使用 LCD 連要找移動中的目標物都很困難

"G10 有電子快門線 , 相信G11不可能沒有吧, 舊的機種都支援..." => 很難講 , G11 規格上沒寫到這一點 , 還要再確認 , 也許 Canon 為了某些原因把舊機有的規格拿掉 , 就像早期 G 系列本就有翻轉螢幕 , G6(還是G7) 以後就沒有 , G11 又恢復有翻轉螢幕 ; 至於 raw format , G9 以後都一直有 , G11 規格上也有寫道 , 目前高階 DC 應該都有  raw format 儲存

P.S. 以上討論只在接 DC 的 digiscoping 上 , 至於 dslr 版 digiscoping 應該沒有觀景窗的問題(dslr 本身就用觀景窗拍攝) , 但小弟不喜歡用 dslr 做 digiscoping (畫質看起來沒有比較好, 焦長沒有比 dc 長)...

Canon A640 + Kamakura 83ed

SONY V1 + Kamakura 83ed
雖然 V1 只有 500 萬畫素 , 但我覺得 SONY V1 對明暗細節(對比) 控制的比較好 , 當然也可能因天候場景不同 (跟上一張拍攝時間相距約一年) , 若我沒看錯資料 , 聽說 G11 的感光元件改採使用 SONY CCD

Author: cgeoff Time: 15/12/2009 21:28

I'm about to buy a digiscoping outfit. I plan to buy the Swarovski ATM 80 HD.

I was wondering if anybody knows whether the Canon G10, which I have, works with the Swarovski UCA adaptor, or the DCB?

I particularly need to have the ability to switch quickly between observation and digiscoping. Does anybody know which of the two adaptors is better in this respect?

Thanks for any help.

Author: Robbin Time: 15/12/2009 23:23

cgeoff：
The UCA DCB is allegedly for DSLR and DCs's, I have seen a Canon DSLR mounted on it, so I thk it will work for G10 or G11 as well. Meanwhile, I think yr safe bet is to take a look at the specification of the SWA adapter to see the weight limit it carries.

And there are a lot of swing arm camera adapters such as Baader camera adapter, Zhumell swing Arm digital camera adapter around, if U want something less ostentatious， less conspicuous, take a look at them as well. They aren't as elegant as the SWA adapter, but a lot less expansive.

Many thanks indeed, Robbin.

You're right, the Swarovski adaptor is not cheap. I hadn't realised there were other alternatives, so thanks for those. I'll check them out.

From YouTube, it seems that the UCA involves a single smooth movement to take the camera out of the way, whereas the DCB involves the removal of the camera from the set-up, albeit fairly easily. I guess that's why weight is an issue with the UCA.

Guess I may have to go to the Swarovski showroom to see the two set ups and handle them for myself.

G10好Sharp，用Canon G系列就是有信心。
有个问题一直困扰着，月初时用老机器Canon G2+Pentax 80ED，最近买了GH1，接上后用很多手动镜头，但效果都不及我这部古董G2，搞不懂

记得当年从G1开始买，这部G2已经是第二部G2，之前的G1和早一部银色G2都有失焦问题，偏后和对焦点偏移问题，当时经常去Canon CS都不能解决问题，
一直到换了现在手中这部黑色G2才没事，后来换单反就没接触G系列相机了，我觉得相机调教准度可以分别很大，当然现在的QC比以前成熟多了。
现在我有点担心我是否遇到以前同样的问题，也有可能GH1接手动镜头时产生的问题。
不知道用GH1接其他廠镜头用的C-hing有没有遇到这样的问题？总是觉得图片不够Sharp，当然不是脚架震动做成，但不排除快门帘做成，
或者是相机本身没调节好？我用的是日本menu的水货机，看不懂，有無C-hing帮手？
谢谢！
