OK, I've done a lot of searching but most articles refer to damp ingress due to taking a lens from a warm to cold climate and vice versa but this is not my worry.

I intend to spend up to 8hrs a day in the rainforest where relative humidity can be as high as 100%. I'm wondering about the possibility of moisture ingress and subsequent mould due to the zoom action. I've already collected a bit of dust inside so I'm not convinced that the seals are as good as some claim them to be.

Opinions welcomed as to whether this is just an "occupational hazard" that one has to contend with in these environments?

Yes, mold can grow in these conditions. It doesn't matter much whether you zoom or whether it is a fixed-focus lens, the humidity will get into the lens and camera body.

If you store the gear in a low humidity environment for the other 16 hours of the day, you might be all right.

Photographers who live in very humid places have special storage cabinets for their gear to prevent harmful fungus growth.

C&C always welcome.

Yes Kim ... Yes I was. I was wishing I had the 70-200 on.

Lucky to get a shot at this feller. I only saw some movement and couldn't even recognise it as a bird due to the dark and it's camo. Anyways, banged away and the resulting pic surprised me considering that I had no time to up the iso and the shutter speed was 1/20sec. Says a lot for the IS on this lens

Like many others, it's largely due to this thread that I also have purchased this lens. Never having had a lens this long before, my best efforts are (hopefully!) still ahead of me, but here are some attempts from the past weekend - my contribution to bidkev's fantastic work documenting the birds of Australia!

Cheers

Alec

You're welcome! I'll be following your rainforest excursions with interest - esp. how your gear handles it, as I also would like to spend some extended time in that habitat. Visited Cairns for the first time last spring - time was short, & I still haven't seen a cassowary or tree kangaroo in the wild (let alone a cuscus!!), so I am determined to get back and really explore the area. For us it's a bit like N. Americans going to Costa Rica :-).

Cheers

Alec

Long lenses are addictive! Pretty soon, you'll be lusting after the big white primes!

If I don't get the shots I want with the gear I have, the only optics I need to examine is the mirror on the bathroom wall. The root cause will be there.

If you're visiting Alec, I recommend Lamington National Park for wildlife either Binna Burra or O'Reillys campsites for self sufficiency, or you can glamp or lodge at either, although they're somewhat expensive. I avoid both myself and prefer to camp "rough it," albeit with hot showers :-) They're both busy at weekends and holidays so book well in advance O'reillys being only $6 a night. I always go mid week outside holiday season and never weekend for the peace and to avoid the (noisy) tourists scaring off the wildlife
