5D3是否有点测光与对焦点连动?
虽然这问题有点不好
因为一切都要等实测才能知道是否像规格写的一样漂亮
也包括这个问题的答案
不过做了一下功课 跟大家闲聊一下
http://cpn.canon-europe.com/content/product/cameras/eos_5d_mark_iii.do
5D3里面的规格只写
Metering Modes TTL full aperture metering with 63 zone Dual Layer SPC
(1) Evaluative metering (linked to All AF point)
(2) Partial metering (approx. 6.2% of viewfinder at centre)
(3) Spot metering (approx. 1.5% viewfinder at centre)
(4) Centre weighted average metering

1DX里面的规格却有特别写出有连动
Metering Modes TTL full aperture metering with 252 zone from
100,000-pixel RGB AE sensor
(1) Evaluative metering (linked to all AF point)
(2) Partial metering
(3) Spot metering:
Center spot metering
AF point-linked spot metering
Multi/Spot metering (Max 8 spot metering entries)
(4) Center weighted average metering
看样子是没有像Nikon那种测光与自己选的对焦点连动的功能

不过在这页的第2页里又有写到
The EOS 5D Mark III always measures focus with all AF points, regardless of
the selected AF mode. During the exposure reading the camera looks to see
which points, in addition to the selected point, have achieved or almost
achieved focus. This information lets the camera know which part of the image
is the subject. It then takes metering readings from the zones corresponding
to the AF points that have achieved (or almost achieved) focus and combines
them with readings from all the other zones. This allows for consistent
shot-to-shot exposure, even in complex situations.
With Evaluative, Spot, Partial and Centre-weighted metering options provided
photographers can choose exactly how the light in a scene is measured to
ensure they get perfect exposures every time.
意思就是曝光资讯会随所选的点的区域 相机会判断曝光....
所以自动就好了 囧>"

1F：推 ejywar:记得前面的文章有提到是用7D的测光系统，那理论上应没连动 03/02 23:30
2F：推 orz007:意思应该是权衡曝光会依对焦点改变加权 但点测只有中央? 03/03 00:23
3F：→ vchenkoshe:楼上正解 03/03 00:35
4F：推 kizuki33:楼楼上错误，只有在点测光模式对焦点和测光点才有连动； 03/03 00:48
5F：→ kizuki33:其他测光模式不会连动，一样是用中央点，1D系列接是如此 03/03 00:49
6F：推 skullfox:权衡式会连动吧.... 03/03 05:59
7F：推 skullfox:刚测了一下 权衡"会"与对焦点连动 无误 03/03 06:10
8F：推 onebow:权衡会连动+1 03/03 09:50
9F：推 logi:kizuki33错误 其他人正确 03/03 12:14
10F：推 ginnietulip:都权衡了还不连动...这要怎麽权衡啊 03/03 12:33
11F：→ ginnietulip:至於点测只能用中央...那根对焦点只有一个有啥差异呢 03/03 12:34
12F：推 kanebo998:用AEL...... 03/03 13:18
13F：推 ejywar:其实最正确的是orz007前辈。因为毕竟〝加权〞跟〝连动〞严 03/03 14:28
14F：→ ejywar:格来说还是不大相同 03/03 14:28
