Will magnetic field from speakers or tv do any harm to the DSLR camera and memory card?

yes... they'll wipe out your data, cause banding in your sensor and worse, create sparks in the electronics...

thats if, there is a very strong magnetic wave leaking from the tv set... but before that, i guess the tv would burst into flames 1st...

I dun think you can find those unshielded ones easily these days

memory cards and MD will be affected if the magnetic field is strong. Apart from that static charges can also kill yr cards and MD. I have small ESD shield bags for my cards.

Better be safe than sorry.

Wot about those airport x-ray scanners ? Save for memory cards, right ?
Actually, I always put inside my pocket, just in case.

Wah, wu ngiah boh ? :bsmilie:
The scanner so clever ah, can manipulate jpeg/raw (can tell difference between brands some more).

IIRC, Solid State Memory Card will not affected by magnetic field. MD or Micro Drive (in form of CF card), which is actually small version of hardisk is affected by magnetic field since they record and read data/memory on magnetic surface disk.

Static charges can kill Solid State Memory Card and MD. Solid State Memory Card may have higher chance to damaged by static charges/electricity.

You can also killed by static charges. Powerful static charge I mean ==> thunderbolt.

Depend on how powerful is the X-ray, it can affect your film (used or new one). But it is safe for memory cards, solid state or MD.

So if i hold a memory card and run on a rubber carpet, changes that the memory card get killed is higher? static charge build up?

Theoretically, DSLRs and memory cards are made of electronic circuit, which is actually electrons, which is affected by magnetic fields, but you would need a very powerful magnetic force to affect the tiny electrons, example the powerful magnetic force created by a nuclear bomb.

Thanks for all the info. I will shift my dry cabi to safer place. Better be safe.

if you find it a fuss to shift the cabi, you can always buy a few lead wallings to protect your cabi.

Agree with you.

But, until they developt self processing film (like those polaroid camera), I think convenient is still on digital camera.

Thot lead only protect against radiation ? To shield from EMI, you need a grounded metal casing to surround the whole cabi :)
