ermm, the 3 i mention cost min of 2xx to 4xx >.<

the 150-200 might be fakes one ~.~

depend how deep the scratch, some claim some polish will work, but i never did that. i uses glass protector.

keep the cap and filter ON, by opening and putting them back will give chance for dust to get it. and its okay to leave the lens mounted when store in drybox.

avoid changing lens on the beach too, sand particle in the air (or salt particle from the sea vapour under hot sun, wind blow, reason why ur hair is so salty and dry) is dangerous and very bad of the internal of the camera.

it could be just some minor connection error. check ur lens chip contact, if its dirty, rub it with the blur eraser (for pen) and try again, it could be just minor oxidation on the lens chip contact.

that's fungus. usually we send to shop, because they have the tools to open and clean it. do it ASAP, the fungus will grow and spread. unless u know how to service a lens, then u can do it urself.

if its an USD/SSM/HSM/SWM/MMMMMM lens, better send it back to original manufacturer for service.

down at night? analog or digital? could that u set the display to degree celcius rather then RH? some drybox can set to display RH or C.

Petre: ur drybox seal may leak or the reader is broken(semi broken). u can get a digital RH reader online and test it again to confirm is reader or sealing.

Cinta Laura: sorry, i am from sarawak, not sure where in KL. i heard a place at mutiara plaza/complex at jalan ipoh got. not so sure.

if ur lens just kitlens, its not really a problem, just go out and shoot often, let it meet sunlight, even our skin will grow fungus if we stay indoor for 1 month.

drybox investment is depend on ur lens investment. dont dare ur house is made from drybox, if u own lots of goodie lens, get a drybox just for it.

You can use drybox in air cond room with no worries. Aircond actually dries up moisture in the air. Mine in aircond room whole night.

shepiroth: no that is nonsense by other paranoia that it will damage the coating. Btw, why didn't ya buy filters for your lens in the first place?

junhas: just brcause, yes, clean it with a dam cloth will do. It's suggest that you jab a dry box for the lens after the trip to remove moist caught in The lenses.

karlpulanco:
1. not recommended for long term, just bring it out to meet the sun at least once a week.
2. its not the temperature that is concern, but moisture (RH%) in the air. just take it out and meet the sun at least once a week, erm did i mention that earlier?

the sun helps 'dries/vaporize' moist away. also help reduce fungus from growing (ppl claim the intense heat from the sun will kill the fungus seed, cant confirm.)

hi, well, since u bring ur DSLR oversea, definately is for shooting rite? shouldnt be a problem since i bet ur camera will meet the sun during shooting right?

2 week is a short period, as long as u move ur bag around, the moving air is not a ideal condition for fungus, so chances it grow is LOW.

err? the dust maybe is inside? u have to unscrew from lens to clean it?

B+W is known as easy to clean off oil dust and smudge. dust even blower can blow it away. but i think the dust is not on the filter itself?

louis, there is 2 type, the round white type that changes color from blue to red, and rock type.

the rock type cannot be recycle.

the color type, we dont use microwave, oven yes, fry it like kuew tiao, yes.

if turn blue, its fresh!!! good if turn to milky white, its full of water...

slightly. if u have your aircond blowing directly only it, it seem to will go up by 1-2% RH.

but if its not blowing direct by a airconditioned room, it seem after u open and close, the RH will drop faster then non airconditioned room. that is my experience.

leave some space behind the drybox and the RH will drop more steadily.

erm, there is a lot re-badge filter by branded company. as for sigma i have no comment. if you are looking for a reliable one, Hoya and B+W is still the best pick

Vcys86: i think u asked in wrong section.

30% is too dry for rubber, it will eventually destroy the elastic of rubber, not sure ur wonderful drybox has auto re-moist the box, else, open close the box few times to let wet air in.

45% is your targeting RH.

good question. unlike those boxing, they are dry in the first place. and during packaging, i believe their factory is very clean. and shop is wipe everyday. no leather or wet cushion or "bed" nearby to store fungus spore...

then why does our lens is prompt to fungus? because we took it outdoor, humid area, dust, zoom in and out, sometimes, got rain on, or during rainy days, room RHumid can reach 90+, and there is a lot fungus spore in the house, especially your room, ur bed has like 98% fungus spore.

Drybox has many type, analog or semi digital or full digital.

analog uses a, well analog reader, and fader switch for u to control how powerful the drying process, which u have to check now and then for the right RelativeHumid %~

semi analog uses a digital reader, more accurate, but still, a fader switch where u need to adjust if its too dry.

full digital, well, automatic stops when desire RH reached. and runs again when its wet(opened). best thing bout full auto digital is, if its TOO DRY, it has ways to make it back to wet again

eg: accidentally hit 40%RH when ur setting is at 45%, it will let its "iced" melt back to wet back the drybox.
