Auto ISO: Is this more of a problem than a solution?
Aug 7, 2014

Just to clarify further, re what I was trying to get a further discussion about:


If one uses Aperture (AP) priority and Auto Iso, the Shutter Speed (SS) often defaults to 1/60 sec, which is too slow for scenes having any movement. And if one uses Shutter Priority at, let's say 1/125 sec for average moving scenes, Auto ISO often defaults to the widest Ap, let's say f/4 or less--which for a street shot produces a shallow a DOF, often undesireable.

It would be helpful if Sony's Auto ISO would allow setting a maximum diameter f stop, so that when setting Auto ISO and a Shutter Speed of 1/125, one would still be able to control Depth of Field. Then, only ISO would automatically vary, and one could have relative control over the AP and the SS. This would be an excellent firmware upgrade.

But lacking this, the best way to control one's shots is to manually set an ISO which best allows a SS and an AP nearer one's choice. I find Auto ISO just doesn't serve well when street shooting, although it's commonly used (see the above-mentioned thread).
