請問E-3的動態追焦能力如何?

昨天傍晚看到一堆燕子飛來飛去

順手拿起E-3 + 50-200mm舊版〈無SWD版本〉,測試C-AF。
不過由於黃昏光線偏暗,因此為了維持快門,ISO使用800。


獻醜了







有看到外國文章
開c-af...用5點對焦...

用有swd的鏡頭追焦

成功率都不錯

可以請您分享一下那篇文章的網址嗎?

我是滿希望有機會可以親自體驗看看,只是那也要有大大願意協助才行。

最大光圈最大是f7
還是f3.5再加兩格??


f/3.5 - f/4 - f/4.5 - f/5.0 - f/5.6 - f/6.3 - f/7.0
-- 0 -- 1/3 -- 2/3 -- 1.0 -- 4/3 -- 5/3 -- 2
是加兩格沒錯阿

2x鏡光圈下降2格
1.4x鏡光圈下降1格

內有很多作者經驗 包括不同場合機身設定

從4/3 PHOTOGRAPHER MARCH 2008第7頁開始節錄:

"Again I should say that for different situations
different methods will be appropriate.

If shooting a football game — I would probably start with
C-AF, Release Priority on, Diamond focusing pattern,
focus points Standard. I would shoot ESP metering
— most likely tied to the AF point. I also
would probably be shooting in Shutter Mode (vs.
Aperture, or Priority) with the minimum setting of
1/1000 or faster shutter speeds and have ISO set to
Auto with my limit around 2000 ISO. Here I am
just trying to focus on the guy with the ball.


If I was shooting an available light portrait for
a wedding or similar scenario I would be in S-AF
+MF, Small for small focus points, Release Priority
off, Single focus point toward the to edge of the
frame, My metering in this case would also most
likely be set to ESP + AF. My ISO would most
likely be either set to ISO 100, 200, or auto ISO to
max of 400. I would either shoot Aperture Mode, or
if light is low shoot Shutter Mode to keep enough
speed up to reduce blur — like around 1/125 second
of f2.0-2.8. I would be trying to focus on the
eye.


If I am shooting a landscape, I want a large
depth of field to get milky water. I want to save
all the highlights. So I would use either MF or
SAF+MF, with metering probably ESP. I would be
shooting Aperture Priority, ISO set to 100, Mirror
lockup and I would either have a remote cable or
self timer on the camera. The camera would also
be on a tripod. Shutter RLS priority would be set
to off. My DOF would be at least f8 or smaller.
However, I would imagine that the diffraction limit
(where the image begins to degrade from the size
of the sensor) will begin to start showing up after
f11. "
^^ 今天雖然是雨天 但是出門試了一下50-200 +EC 20的組合

光圈在陰天真的不大合適 但是白天的對焦速度也挺快的

只是畫質的確下降不少

官田水雉 有上腳架的!

功夫不好 來個屁屁連拍!

追焦如果抓好 成功率的確很高 這幾張是手持拍的!

^^ 我覺得人為因素很大 追焦沒拍好 通常是我沒對到目標

電烘~~你拍這個是超高難度的~~如果有去官田那個水雉棲息區拍過的,
就知道,現在拍攝區離鳥有多遠~~都是無限遠對焦~~連我用300/f2.8+ec-20,
拍到的鳥,都非常小,以下照片有稍微裁切,陰天拍攝~~

3.來張限制集的,水雉全台就官田那幾隻而已,這畫面非常珍貴~~

[流口水] 神鏡就是神鏡 加EC20 畫質還是一樣很好!

還好太貴了 完全沒有購買的欲望![好窮]

不過今天運氣不錯 遇到兩次離很近的!

下次找一天好天氣在去戰一次吧~~
通常下午三至六點是人最多的,
也是現在繁值期,最有可能遇到交配的時候~~
水雉在交配的前幾分鐘,會沖一下水,
之後就飛奔過去了~~~短短的不到三十秒就搞定了~
