i dunno what u guys think, there is once i try a test with my drybox. i left it open,  daytime, nighttime, days with A/C and without A/C. and raining days.

i dont know what the the % that encourage the fungus to grow, but let me tell u the result of the test above.

this reading is the % of the with the door of drybox opened.
=================Day Time ========= Nighttime
Hot day windows open ------ 60++ -------------------- 60++
A/C window closed----------- 50++ -------------------- 50-65++
Raining ----------------------- 70-80 -------------------- 80-90%

* even with closed drybox door closed, the AC will still bring the humid in drybox up by 2-5%, sometimes i see my drybox at 47%, which to me is fine.

i am quite surprised that the air cond dont really create moisture, but the metal will have moist on it. but it's dry enough.

seeing raining days humid is so high, i doubt u can even escape it from putting in a bag. NOR the humid-fier or moisture absorber could actually drop that 80% to anything near the safe 45%

if fungus are active at over60%, then 3 days of raining day will spawn spore of fungus in ur lens already. and who knows, if u put in ur closet, or someplace dark, it is wet (over 60%) all over the whole days.

some people my not think thier lens are not that expensive or worthy to get a drybox yet, until 70200G comes along. but imagine this. WHAT IF, THE SENSOR Gets Fungus? hoo hoo, i think is time for new present for christmas? a550 anyone?

yup, MF but its not that hard to MF due to larrrrggee DOF. well, i would say it's half of sigma price and this lens is added arsenal to my wedding shoting.

Banzai_san: i dont know what word in english, but 'hama' is something like very very small bug.

* removed, choose to PM instead to get the fact straight. scare i scare him away 
in 7FPS mode. the camera will preform a mirror lock up, which prevent any AF possible. and the 7fps mode, the camera will choose the constant settings from the first picture, meaning it will use the same exposure and af lock for the rest of the photo until u let go of the shutter release button.
