L series lenses

I plan to take pictures in a high humidity environment and was informed that the L series lenses would be best for this environment.

When looking around for lenses, I noticed that the L series lenses seem to be 70mm and greater (common 70-200mm). What lenses would you recomend for the following photos

close up of snakes, frogs, lizards
landscape shots
birds in flight

Thanks

They do have "L" series in lenths less than 70mm: Here is a list.
EF 14mm f/2.8L USM
EF 24mm f/1.4L USM
EF 35mm f/1.4L USM
EF 16-35mm f/2.8L USM
EF 17-40mm f/4L USM

I am not very versed in close-ups so I'll let someone else tackle that question.

You forgot the 24-70mm f/2.8L

by that order:

canon 100mm macro
canon 17-40L
canon 400mm f5.6L or canon 100-400L if you want zoom.

For what you listed I'd go with the 300 f/4L IS with a 1.4 TC and the 17-40 f/4L. The 300 has a nice close focusing distance as well as nice reach so you won't need to get so close to your subjects, add a 1.4 TC and you've got a nice bird in flight lens. Throw on the 17-40L for your landscape shots.

throw some extension tubes on and get really close for not a lot of dough.

How much money are you thinking?

100-400 lens would be wonderful for the in-flight shots!

The 400 5.6 would be much better. Insanely fast AF for 400mm, small, light, and exceptional IQ. Cheaper, too!

How does that canon 100mm macro lense hold up in high humidity??

Is it considered an L series lense??

Love the photographs I have seen online with that lense.

It's not an L, and it's not weather sealed. I've gotten condensation in/on mine before. Still works, though.

Not all L lenses are weather-sealed either. And weather sealing's meant for active precipitation, not for general steamy conditions of high humidity. If you're in a high-humidity environment but not working in the rain, just rely on storing your gear in air-tight cases with dessicant to absorb the moisture from the air.

How does the 400L compare in IQ to the sigma 50-500?

The environment will be 85-90% humidity (I imagine 100% humidity and no rain is also possible in this environment) will a 30D withstand operating in that environment??

I noticed that the 1 series say operating environment < 85%

i've hard that only the 16-35L, the 24-70L, and the 70-200IS L are the "True" weather sealed ones...my 17-40 is sealed but only if i add a filter to the lens...same with my 24-105
