Sony A580 Third Stop ISO???
« on: February 21, 2014, 05:38:05 PM »
Hi All,

Does anyone know if the Sony A580 can be changed from the basic ISO range....eg, 100,200,400,800 etc, to third stops like the A700 can, eg..100,125,160,200,250 etc.

I find the Sony A700 extremely useful in being able to do that, but maybe the A580 series it isnt possible.

I thought that the A550 wasnt possible but the A580 was, according to DpReview.


Your help is you can


Thanks
Graham

Pardon my ignorance but why would you want to change ISO by such small amounts?  ....john

I think its hugely useful

My A700 I feel a jump from say ISO 400 to ISO 800 is huge when I can choose 500 or 640 and just keep slowly shaving down the ISO and improve image quality

I also shoot at the third stops, it gives you little bit extra at times when you need it, its one thing I love about the A700, just wished it started at 50 ISO though.....
