Auto ISO Behavior

To Martin, Erik and Longo0,

Thx. It's true that I learned to use manual ISO before auto-ISO became available and therefore that I'm used to it, but I suspect that many people who do use auto ISO also learned photography in the same era. After many years, I simply internalize the thinking about the exposure triangle and know what my camera is set to - these days it's even displayed in the EVF for you.

There are some reasons. I never have to turn auto-ISO off for situations when it's not the ideal setting. Another reason is probably coming from an XT1 where higher ISO IQ fell away fairly quickly compared to later sensors, so containing auto ISO to a relatively narrow band seemed a bit pointless. I've yet to experiment with the high ISO IQ of my new XT4. One's personal approach to photography probably also matters.... I'm a contemplative shooter and thinking about ISO has never limited the attention I can give to composition. Perhaps if I was shooting in some fast and furious situation I'd find auto-ISO a great benefit.

Thank you for your contribution. My main impuls to start with photography more seriously was birth of my daughter 4 years ago. So she is my main subject. And I wanted to focus on composition and what she do etc., not camera setting. So maybe this is the main difference - sometimes it's really the fast action, on the trips also with changing conditions shade/sun etc., when autoISO comes really handy.

My reasoning is also, that ISO is the only exposure parameter without artistic meaning. You just wanted as low as possible. Well, automatic setting do it best without hesitation! 😁

The only one feature I miss on today's cameras - custom setting of minSS on the wheel instead of SS! It would be perfect for my style of exposure control.

As always, it simply comes down in the end to what you like. I guess it's like cars. Some people like automatic transmissions, some prefer manual.

Well I drive with manual transmission. The difference for me is, that automatic transmission sometimes do what I don't want...but autoISO I can set exactly like I want.

Cheers, Rod
