Going to photograph some a live volcano.. Help!

[The_blue]

In 3 weeks i'm off off to Stromboli on the northern coast of Sicily.


I want to get a shot like this or better...

Exposure 20
Aperture f/8.0
Focal Length 175 mm
Focal Length 174.5 mm
ISO Speed 200

no exif

I'm taking the tripod and Canon 30D but think I'm gona need a new zoom lens, my old siggy is sick and not worth the repair..

I've looked at the canon 18-200 IS, tamron 18-270 and siggy 18-200 (i think).

All seem much of a muchness in that bracket.. I'm looking at 2nd hand.


Has anyone done it and have any tips? Has anyone got any comments on the lens options?

yeah, a little. I'm hoping for a walkaround single lens solution.

Thanks guys!

Don't think i'd get the use out of the 70-200 I travel light and that would take too much room up.


I've gone for the Tamron 18-270mm, if i don't like it it's back on the bay
