Hi,

I'm trying to make sense of the auto Iso settings on the M240. I'm used to setting the max ISO and a minimum shutter speed - most other cameras I have used. However, what is the point of the maximum shutter speed setting? Apologies if I'm being stupid 😕

Thanks

Yes - confused me on first use. The setting is not maximum shutter speed but maximum exposure time which is a perhaps particularly “German”  way of expressing the minimum shutter speed....... 🤔

They are equivalent.

Set the maximum exposure time to say 1/30th second and the only available “exposure times” which are below that maximum are 1/60th second etc and up. I.e. faster shutter speeds.

Hi,

Exposure time is the correct term and concept. The shutter ‘speed’ is, as much as possible, constant and very quick: it simply means how quickly the shutter mechanism opens and, after staying open for the desired time, closes. How long the shutter is open is the exposure time. “Shutter speed” has been used as “exposure time” by just about all photographers, but it is important to know what is what.

Hi @Jean-Michel,

Thanks. I do understand - I've been photographing for a lot of years. It is using non standard terminology that threw me. Every other manufacturer that I have used lets one choose maximum ISO value and minimum shutter speed not maximum exposure time. The former has become akin to a control stereotype so seeing maximum where one expects to see minimum is the problem. It's not about being technically correct it's about common standard usability.

I'm not quite getting the question, the title is about ISO but you complain about the max shutter speed.  Anyway, where is the max shutter speed in the menu are you referring to?

I misread maximum exposure time as maximum shutter speed so it was my mistake. The two vaiables I expected to see were maximum iso and minimum shutter speed not maximum exposure time. When pointed out to me I realised my mistake.
