Z3: serious banding with new firmware

I had a satisfactory amount of banding until this time. But.

This was made after upgrading to 1.02: http://www.pbase.com/image/34151909/original

I made about 10 shots of this bug, all of the show similar amount of banding. I quickly made some more contrasty test shots of other subjects. No banding.

Still investigating. Will let you know if I find out something.

Re: Z3: serious banding with new firmware

Maybe interference from some nearby radio device (i.e. mobile phone) when shooting or when transferring the pic to the pc?

This banding looks completely different from the one I experienced and it looks like the noise I got on some scanned images that was caused by a powerline running along my scanner's signal cable.

It's not firmware dependent

I've reverted back to 1.01e, and experience the same thing.

Yes, it's possible that it has something to do with electronic interference, since the camera is about 1 cm from the wall of the house where there can be some wires. I'll try other locations.

I've had my Z3 for about a week now and have shot about 500 photos in every situation and mode I could think of (almost equally in firmwares 1.00e, 1.01e, and 1.02e); shooting within a few centimetres of a computer monitor, 220v speakers, and having the USB connection cable running over several power, network, and other computer cables and ending within 5cm on my 19inch CRT monitor and within 12cm of a large (and turned on) speaker), and I have not had any banding (I had to look at your photo to see what you meant) or any other image quality problems.

On the other hand, I have a few small annoyances such as the fact that the T shutter speed in manual mode only seems to go for 15 seconds and even that shows a LOT of hot pixels. I will have to have this serviced, but I don't want to part with my camer this early on :).

Hehe, it looks more like interlacing than banding.

Old problem?

It looks very similar to the examples Armed Monk showed two weeks ago.

But there was it together with lens flare.

My conclusion

My test was not very scientific, but I think there is a good chance that my speculation is correct.

In my test, banding showed up when shooting metal objects or other objects close to metal surfaces or electric wiring in Super Macro mode. Banding was the most severe when the metal object was shot close to a metal surface.

From this, it seems to me that the camera is very sensitive to electric and/or radio interference. This would explain why people experience different amount of banding: it may depend on jewelry you wear, where you keep your mobile phone, what is your clothes made of, etc. For example, I don't wear jewelry (not even a wrist watch), my mobile is usually in a waistbag and never wear synthetic clothes. It would be interesting to make a poll about how banding experienced is related to these.

You need to set drive mode to Single to access the T speed. Maybe there are other settings that can prevent its access, I don't know.

Re: My conclusion

James Bond, those lines are lines I would worry about...

How many percent of your shooting showed this result?

I will try my cam this afternoon to see if it is as good as always.

Good luck resolving your problem.

Last week I was taking a bus home and taking pictures of rain drops dripping through the ceiling (yeah, I was bored) when the bus passed by some road construction. I could see the interference on the LCD, wavy lines that were very obvious. It quickly passed, but I was taking continuous shots while this happened. The wavy interference ended up on one or two of the photos.

I don't have the pictures here, but if anyone is curious I’ll upload them when I get home tonight.

The interference I got didn't look like the banding, but I suppose there could be different types of interference that cause it.

I meant that it goes to T mode fine but after pressing the shutter button it only exposes for max 15 seconds then changes to "Processing" and then saves the image, I thought it was supposed to go for 30 seconds or as long as the shutter was held down.

I tried, it works fine for me. But you don't need to keep the shutter button pressed during T exposure, maybe that's the problem?

I leave that to our Japanese friends. I wouldn't be able to squeeze a response out from KM Europe on any topic.

I think this issue is related to the size and complexity of the camera.

Re: My conclusion

I met this phenomenon only today.

You could try if you can reproduce my problem. Shoot a metal object from 1 cm in front of another metal of close to a wall socket. I used a darts arrow in front of a metal garage door. Let's see what happens.

(Just tried it again) Oh thanks, it was user error, I always had it set to Self-Timer on T which apparently lets you select T but only works for 15 seconds

Works now

Re: My conclusion

I have found KM to be quite responsive to e-mails, I have had several communications from Sham Chada (not all of the very useful though) at:

Konica Minolta Photo Dimage English Support
dimage-support-uk@phe.konicaminoltaeurope.com

They usually take 2 or 3 days to reply.

Another test

Here's a crop of a picture shot while I was talking on my mobile. Noise is OK since the pic is ISO 200, but there are also several horizontal stripes.

Banding on A70 and possible solution...

Guys, believe it or not, there are complaints on another forum site about banding with the Canon A70.

I was skimming through some posts earlier today when I noticed it.

One user is reporting that banding problems go away when you turn off the shutter sounds.

So, this tends to indicate that it is related to electrical interface (or at least voltage levels), as James Bond 007 seems to have found.

This may not help a thing on the Z3, but you may want to try taking some photos in controlled conditions with and without shutter sounds enabled (as strange as that sounds -- no pun intended).

99.5% of all my pictures were shot without shutter sound.
