Will be going to KK for snorkelling trip after my reservist this march and wondering if anybody has used those waterproofing case for their sony DSLR. I think they're called DigiPac and AquaPac ... or something like that. Reliable?

there was a previous recent thread on this in alphadslr.com. go look for it. the conclusion was the digipac or a diy ziploc bag solution, the diff being price - the digipac costs a bit, and the ziploc is well, cheap.

however the requirement was water-resistance. if your requirement is water-PROOFING then the digipac may be the only viable option. but there are limits to this. typically hard-cases are designed for pns cams, haven't seen anything for dslr...

Thanks bros for your advice. I think I'll just use my old Sea & Sea underwater film camera for the time being.

I have 2 concerns with such waterproof bags.
1) Would the setup with dslr in it be negatively or positively bouyant i.e. will it float or sink?
Positive bouyancy would mean having to force it underwater whilst negative would mean you better be one heck of a free diver if you drop it. :o
2) Is that any safeguard against accidentally opening or leaving the bag open when entering the water?

haha i asked before.. but seriously, it's more worth it to get it from Singapore.. i was quoted ridiculously high price from Korea..

also, ever seen MS Color carrying the compact camera version of this brand.. but were told that they do not want to carry the DSLR version.. reason being, if "accident" happens who's going to be blamed.. apparently MS Color do not want to get involve in things like this..

in fact, I also have one for my Canon IXUS 80 IS and Lumix LX3.. it worked perfectly when i went to beach in Sentosa 2 months ago.. :)



To answer bro Lone Wolf's question..
1. It will float due to the air trapped in it (this is based on the experience with the compact camera version).. DSLR has certain weight, you might want to try out.. or make some physics calculations.. =)

2. the safeguard (if it's the same design as the compact camera version), it should have a air-tight (so are water-tight) seal.. and a velcro to prevent accidental water entry.. it works in this way, after you sealed the air-tight seal.. you will have to fold downwards (about 2 or 3 tight folds) and there will be a velcro for you to secure the folds firmly.. it looks pretty unlikely for water to enter.. trust me.. :)

Thanks especially for the information where to get it.
I think it is meant more for in-water photography such as boating, rafting or on the beach. The 3 meter depth (about that of public pools) design is really not much and would not be suitable for skin-diving.
Water pressure increases with depth at roughly 1 bar (approx 14.7 psi) for every 33 ft so what is waterproof at the surface may not be so at depth. One has to remember that this pressure will compress the air (and the bag) into smaller volume quite rapidly as depth increases and this in turn will result in drastic changes in bouyancy.
Also, light levels and colours change rapidly with depth and the rate is also affected by clarity of water and time of day (angle of incidence of the light). You will need flash to take colour photographs when skin-diving.
So if TS means using the snorkel to breathe whilst he is surface swimming with head underwater, it would work but be careful of being lured to dive down to the coral bed.
