Variations in Compact Flash

[drubene]

<p>I tend to shoot a lot of action sports ... namely Hight School Football. I am currently shooting a Canon 40D (RAW 1/500 @ 2.8) and typically do not exceed ISO 1600 while shooting night games. However, during the last shoot, because of poor lighting conditions at the stadium I ended up bumping up the ISO to 3200. I expected an increase in noise in the shots. However, when reviewing my shots I noticed that the image quality and associated noise was significantly worse on the slower of my two CF cards (SanDisk Ultra II vs. the SanDisk Extreme III). Has anyone experienced this and is this normal?</p>

<p>IQ/noise has really <strong>nothing</strong> to do with type of CF card...probably the pictures made were not equal in other ways...</p>

<p>Could you post a sample from each card (with EXIF data intact). As said above, there is no connection between the type of CF card you use and image quality. So, highly likely, there is a different reason.</p>

<p>Like others have stated, the differences were merely a coincidence. You may have fewer shots after the buffer fills, but data is data.</p>
