memorial weekend出门3天，5D3照了400来张照片，32G的卡。我一向是存Raw+S1，这次
回来整理发现，大概有10张左右的照片只有jpg文件，没有raw！就是特别奇怪的在所有
CR2+jpg顺序的文件中，忽然有那么十张都jpg了，CR2整张卡遍寻不见。
这十张是在最后一天的中间部分，不是连拍，都是单张，有时间间隔的，并不是在头或
尾，后面还有几十张带CR2的，这个设置我是从来不改的，也不可能是我设置碰错了然
后又碰回来了啊。灵异了难道。
请问大家这到底可能是怎么回事？太奇怪了。。。
多谢多谢！ |

发帖数: 427 | 2 CR2是Canon的raw格式的照片啊。你把拍摄的照片格式改回jpg就行了。一般的相机都可
以设置成只保存raw，只保存jpg或者两者同时保存。
要打开raw的话装canon自带的digital photo professional（DPP）或者PS的高版本装最新的
camera raw插件。canon的软件光盘里就有DPP，装好后打开CR2文件，然后用convert and save转成jpg。 |

I’m told for certain that a new 50 f/1.4 is coming this summer from Canon.
It will retail in the $699 USD range.
New Lens
The same source says there will be one new lens from Canon this summer/fall
that is not a replacement of anything current. He didn’t have specs at the
present time.
Teleconverters
There are new teleconverters being tested at the World Cup I’m told. No

A good source says “I’d be surprised to see the next 24-70 not announced i
n April”. The source does caution things could go awry because of these app
arent lens delays.
The source also says the lens will be “with IS”.
I look forward to the end of the speculation on this lens.
