One innovation with the new fw really annoys me. Yes you can process a RAW into JPEG "in camera" but it gives the JPG file a different name!
So _IMG_0001.CR2, when processed becomes _IMG_0002.JPG. But actually if you've taken, say, 105 pics, _IMG_0001.CR2 becomes _IMG_0106.JPG. So no relationship between the two files is easily visible.
Wasn't going to use this feature particularly, but annoying nevertheless
Never mind, found it.
Struggling to find "File Name Customisation" after installing new fw.
Anyone had better luck finding this than me?
