Hi all,

I have an upcoming trip to Port Campbell (VIC) and surrounds. My sense is that a lot of the pics I see online of this area are taken with relatively long lenses and look to be taken from various lookouts.

My gear is a 5Ds, EF 16-35mm f4L IS USM and a EF 24-105mm f4L IS USM.

The 24-105 is a great lens but not long and it won't take either of Canon's extenders.

So the question is, is a long lens desirable for the location and if so, what?

Bonus question is what 3rd party lens are comparable to Canon's L series?

Cheers,

Mark
