Shutter speed using electronic shutter.

Just something to be aware of when using the electronic shutter with long lenses in "A" mode.

The camera selects a slow shutter speed and tries to keep the ISO value low.
Using the 40-150 pro lens when zoomed out at 150mm the regardless of the f stop value the camera tried to keep the shutter speed at only 1/20 - 1/60sec, obviously at 150mm this is way too slow, changing to normal shutter mode the camera selects around 1/350th shutter speed and as higher ISO as required.

So normal shutter mode appears to be preferable for long focal lengths in A mode.

Re: Shutter speed using electronic shutter.

How interesting: many thanks for that. Sounds like it's worth trying out with a range of different lenses, and using different exposure modes.

I'll only be using the eShutter commonly for street photography, so it won't matter so much, but occasionally it's very useful for shooting (with permission) in quiet environments like concerts and theatres, so longer lenses are used then.

Maybe way to slow but able to be done. F2.8 @ 1/15sec 150mm ISO 800.



Okay, so this was the third or fourth attempt, and there is still movement.

Re: Shutter speed using electronic shutter.

Hmm the original is much clearer, am I doing something wrong? Noticed this with a couple of pictures lately.

Re: Shutter speed using electronic shutter.

This is how it has been implemented (in Aperture Priority) on the E-M1 now too & to get that higher shutter speed then the ISO needs to moved from Auto to manual up ISO 3200.

Re: Shutter speed using electronic shutter.

There is no flashing of the aperture indicator warning there is not enough light either I noticed. I found this when using focus stacking, so I came off Auto ISO and went manual up to 3200 limit. It does give warning in regular use but images at least 3.3 stops under exposed. EVF and histogram look normal

It does flash for me when longer than an 1/8 sec in Aperture Priority mode & when pushed up to Auto ISO 3200 (with 75-300 lens on).

Ahhh that was the problem, I had it on ISO 200, but still no warning.



In shutter priority I did not have the same problem, as soon as the camera thought it ran out of light the speed blinked. This, as with the other taken in "A" mode are one click before the warnings (Shutter speed, aperture) in viewfinder) started to blink.




So I just won't shoot if I see 1/8 of a second in the EVF when in Aperture mode.
