可以從照片看得出是全片幅或C片幅嗎？

目的, 或者個 "學習點" (learning point) 係咩 ?

定係 "得個知字" ?

因為有朋友說可以分辨，我想不明白，才有此問。

thanks !!!

wide angle會有分別
兩者的分別在於同一距離用同一焦距時，ＦＦ的變形較小
在高ISO時(800或1600)，noise同sharpness 的表現也很不同

如果沒有對比，只單一張照片，能分辨嗎？

Thanks !!!

同像數分不出來

也有aps的高iso表現也很好的,a900反而有點失信

>>兩者的分別在於同一距離用同一焦距時，ＦＦ的變形較小

應該是：兩者的分別在於同一距離用同一焦距時，ＦＦ的變形較厲害。




>>如果沒有對比，只單一張照片，能分辨嗎？

可看EXIF資料，一目了然喇！

淨睇哂左 4R 相... 冇乜分別.

apsc 同 full frame 比.... 要考慮幾樣野.
1. 同一個牌子比較...? e.g. d80 vs d700, d300 vs d700
2. 吾同牌子比較...? e.g. 5d mk2 vs d90, d300 vs 1dsmk3
3. 兩種比較 sensors 是否同一像素...? e.g. d2x vs d700, d80 vs 1dsmk3

而家係講 which one...?

多謝以上各位的指導。

Thanks !!!

yes! for the lens of the same angle of view, e.g. 17 mm on FF vs 11 mm of APS-C, the APS-C 11 mm has the GREATER depth of field than 17mm on FF, u can easily check

[snoopybee]

Obi can you please elaborate? Would like to know the details as well.

My interpretation of your meaning is to look into the EXIF details and find out what focal length and camera had been used, then you can see the diff in depth of field? Thanks.

完則上是分不出,從←張相是分唔到是FF機或DX機拍出來.但用同一枝定焦鏡分別装上部FF和DX機各影同一方向相一張,結果就可分別到两張相是從哪部機拍出來.
