G9 Battery temperature

Well, I thought I was all settled on an Ikelite housing for my Canon XTi, until someone suggested that I look into a G9 instead. So, then I was pretty much sold on the G9 route after some research, but now I've heard from soneone else that he was told that the heat from the battery during operation caused a fogging problem in the Ikelite housing for this camera. I haven't seen anyone mention this, but I thought I'd put the question out there before I commit. Has anyone experienced unusual heat from the G9 battery during operation? Thanks for any input.

If you've got the XTi already, I'd say house that ... but the total cost of SLR ownership both above and below water is a lot higher than the G9. For what it is, the G9 is an amazing camera chock full of features and functionality and with really good image quality at ISO 80-125.

The two big downsides in my mind are:

>> Small sensor - high ISO (above 400-500) is REALLY noisy and 200-400 ain't that great

>> Shutter lag ... much improved over other P&S, but no SLR - not even close

I own the G9 and love it ... and I don't see any reason why the G9 would be more prone to fogging and haven't heard that said by others. Mine's never fogged the Canon housing - and that was with the internal flash popping off to trigger the strobes. In the Ikelite case you can use a sync cord and use strobes without the internal flash which should help. Also, the use of desicant packs to keep it dry inside helps as well.

Fogging is an issue I experienced for the first time last week.

I closed my G9 and Ike housing in ambient conditions - warm (probably 20 celcius plus) and sunny. Almost immediately after immersion into 9 celcius water the glass port fogged so I don't believe it was neccessarily due to the internal flash.

The battery? Probably not as I havn't noticed any heat generated when using the G9 topside.

Because of the large volume of the Ike housing, I have not been using silica gel bags. Now I have two secured with a rubber band under the tray...

That's the issue - cost. Yes, I already have the XTi, but the for the cost of the Ike housing alone (w/o a port lens) I could have the G9, housing and one strobe. I figure if I like it great, if not, it seems like a popular enough rig that I could sell it fairly easily. Thanks for your input.

I notice you are using an Ikelite housing but not the TTL strobes. Any reason why not? Just curious...

Hope that does the trick! I was most concerned with what I heard about fogging from the heat generated by the camera's operation. I know of other people that have experienced this with p&s cameras. But I haven't been able to corroborate this information, so I'm not too concerned now. I'll keep dessicant on hand just in case though. Thanks.

I've been shooting flash photography manually on land for a long time (almost 30 years) and I just like the Sea and Sea strobes ... I was using them before I had the Ikelite housing and when I went to buy a new big strobe to replace an older smaller one, I considered the Ikelites as I was also buying the Ikelite housing, but in the end I just decided to go with the YS-110.

It wasn't until very recently that I started to use anything other than a spot meter. I was kinda snobby about program and automatic "modes". For years, I used an SLR with a built in spot meter and would use my palm and my jeans as my grey card - for example, I know my stretched-out palm in bright sun is two stops over exposed.

I'm pretty much over it ... I do use TTL flash above land now all the time with my family snapsots, and I use program and automatic exposures for my "art", but for whatever reason, I still go fully manual underwater. I don't use the meter at all underwater - I use my instincts and experience to set the right general exposure and tweak the power on the strobes if I get a bad result.

I bet eventually I get a fully TTL-based system ... or maybe I'll add a S&S TTL converter at some point ...

I haven't even used this rig yet, so I'm getting way ahead of myself.
