Hello,

these two photos are from my LX100 from today. I purchased camera a 3 weeks ago, no problems till today. Have you ever seen anything like that?

It is visible not at all photos, much more on aperture 1.7 then 16.

Rather on high iso - but maybe this is not a rule.

I have still 2 day to return camera back to the shop.

I will appreciate your quick opinion.

Regards.

Arek

Are you using the electronic shutter under fluorescent lighting or some other lighting type that might cause shutter artifacts?

Smaller apertures likely increases shutter speed, resulting in less of a problem?

Yes, it was fluorescent lighting in kindergarten.

I've just checked the shutter speed and aperture values and the rule is:

while shutter speed is shorter than 1/125s (e.g. 1/200, 1/500) the artefacts comes.

The shorter shutter the bigger artefact.

So is this normal???

The current LX100 is my 8th camera and I have never noticed anything like than.

And what do you mean by electronic shutter?

Can I switch it into mechanical one or that depends on the camera?

Regards!

This is normal and comes with the switch from CCD to CMOS sensors- perhaps your earlier models were CCD?

This may be more related to the fast shutter speed than the use of electronic vs. mechanical shutter. Fluorescent lights actually flicker at twice the AC line frequency, so 60 Hz in the US means 120 times/sec, so shutter speeds at the or faster rates are subject to horizontal banding due to the CMOS scanning process.

Thank you Bruce.

This is the probably the most complete and professional answer for my post I have ever received.

Thank you:)

Hello, I have the LX100 for a month now, and I experienced the same problem. But not only with monitors/televisionscreens, but also with some sort of led lighting in a room. But it didn't only happen with shutterspeeds above 1/125, but at 1/100 too... And I had the electronic shutter ''ON''... So I think be something else causes this ''fenomena'', which is a bit annoying, because it is visible in black & white as well, when converting from RAW... I hope some of us finds the right answer...

Europe uses 50 Hz power, so I'm not surprised you see this at 1/100s shutter speed as well. LED lighting uses AC to DC converters and many LEDs actually flicker - linked to the quality of the DC converter. Therefore, the effect with LEDs can be similar to that of fluorescent lighting.
 
Switch the electronic shutter OFF when shooting indoors under artificial light. The only time you need it is 1) when trying to freeze e.g. water drops / fast action and 2) as a ND filter outdoors when you need open aperture in bright sun.

3) Silent operation is desired.
 
Aha thanks, I didn't think about the 50Hz... of course... But I'll try using the mechanical shutter, and see if that really works, should it be necessary...

True, but the mechanical shutter is near silent anyway.

I get a bit of machine gun staccato from my FZ200 in burst mode though it's more of a ticking than an annoyance but can easily be heard in quiet situations.

I'll add 4) Prevents shutter shock - though that doesn't really apply to the LX100.
