I'm just happy listening to you guys and gaining valuable insight
As it is I think I will rent the 11-16 Tonika lens, so that should the northern lights appear I'll have a decent chance of getting some good images. It works out to £50 a week, when I come back off Holiday I'll save up for my own wide angle lens which may well be the Canon 10-18.
Just purchased the manfrotto befree tripod today and now need a CPL filter (probably the Marumi DHG Super Circular Polarising 58mm Filter) and a shutter remote then I should be just about set (still need a couple of spare batteries and lens hood)
Off to Lumsdale Waterfall (in the Peak District) at the weekend to practice photographing long exposures with my new gear!
Yeah I've been tempted to rent quite a few times but the price usually puts me off. It's an easy way to try a lens but when you're paying 20-25% of the total price just to use it for a week then it seems a bit harsh. If you had the time and the patience you could buy a second hand one and sell it on after for practically nothing
CPL filters can be useful but they don't add much to the exposure lengths if that's what you're hoping for (you mentioned long exposures). If you want long exposures (especially during the day) then you'll need something much darker.
