iul Posted February 16, 2015 Share Posted February 16, 2015 A question addressed to the A7-specialists: As far as I could find out, the A mode on the A7 (ILCE-7 Vers. 1.10) works as follows: If ISO is not on auto, shutter speed is automatic in the full range, if ISO is on auto, shutter speed is automatic while ISO tries to minimize to 100. As soon as automatic shutter speed would rise above 1/60 s, ISO automatic starts to increase. As a result, automatic shutter speed does not adjust to values above 1/60 s as long as a maximum ISO of 25600 is not yet reached - then it starts to increase further up to 30 s. Is there any way to change these somehow arbitrary limits of 1/60 and 25600 to more specific and useful values ? Link to post Share on other sites More sharing options...

sonycamerasoon Posted February 17, 2015 Share Posted February 17, 2015 You're after auto ISO options I think and I did not see this in the menus when I tried the camera yesterday Link to post Share on other sites More sharing options...
cohen5538 Posted February 27, 2015 Share Posted February 27, 2015 In low light you can use M mode. Select your min. Shutter speed and use auto iso Mark Galer 1 Link to post Share on other sites More sharing options...

I do not have my camera with me, nor would I need to check my camera to say that what you have written is extreeeemly bizarre and cannot possibly be the default SOP of any general purpose camera. If your camera is acting that way, you need to restore it to its default settings. ---------------------------------------------------------------------------- FWIW, I'm uneasy with your description of the camera's behavior. You said: if ISO is on auto, shutter speed is automatic while ISO tries to minimize to 100. As soon as automatic shutter speed would rise above 1/60 s, ISO automatic starts to increase. Those two descriptions contradict each other. An auto-ISO that starts rising when the auto- shutter-speed rises above 1/60 is absolutely NOT an auto-ISO that tries to minimize to 100 during auto-shutter-speed [A-mode] operation. You have not described any possible problem. You have described two separate operations, each of which may or may not pose a problem, but both of which cannot happen simultaneously. ..... if these things are happening at all :-\ ` Link to post Share on other sites More sharing options...
Guest all8 Posted July 16, 2015 Share Posted July 16, 2015 Yes, I have ISO 1600 as the maximum limit. Not sure on the lower shutter speed, that might be possible to... I don't recall. It's all in the manual or the online manual. Sent from my iPad using Tapatalk Link to post Share on other sites More sharing options...
RRRoger Posted July 23, 2015 Share Posted July 23, 2015 Because there are brighter subjects in my backgrounds, I have found Auto ISO to be very unreliable. I shoot Aperture priority for stills and Manual Movie Mode for Video. Link to post Share on other sites More sharing options...
