Trying to decide what lenses to bring to Iceland

I'm going to Iceland for three weeks in the middle of July. This will be my first "fly away" trip since I mostly switched to full frame. I used to travel with my 7D along with two lenses (a Sigma 18-250 and a Sigma 10-20). While not ideal, these lenses covered just about any situation.

Now that I'm using a 6D, things seem a bit more complicated. It's unlikely two lenses will cover every situation so I have to compromise. My "full frame" lenses that are relevant to this sort of trip are...

Canon 17-40L
Canon 24-105L
Canon 50mm 1.8
Sigma 70-200 2.8
Sigma 50-500
Samyang 14mm 2.8
Samyang 24mm 1.4
Sigma 2x teleconverter

Wildlife isn't exactly plentiful in Iceland (except puffins and whales) so the 50-500 is out (plus it's just too damn big). Night photography is going to be limited in the summer so that probably makes the Samyang lenses not worth it either. I'm thinking of trying to get away with the 17-40 and the 24-105 plus the teleconverter. I'd like to have the 70-200 but I'm not sure if I can swing it space wise (I'm also bringing a flash, tripod, etc.).

Anyone care to critique my thinking and selections?

Thanks!

No one has any feedback to offer?

Heya,

I think the 24-105 will be your most used lens. From there, I'd actually take the 70-200. Lots of distant vistas and things. Lots of landscape, and 24~200mm will cover it all. I doubt you'll need as much ultrawide because everything is always going to be far away from you. Unless you're backpacking and getting right up on top of things, the ultrawide likely will spend it's time at the longer end of the range. 24mm on full frame is wide and will cover everything as it is. I wouldn't worry about speed, the 6D's ISO can handle F4 at the night sky with no problems, you can still do some fun long exposure night sky with it and get good results. I would not bother with a TC but that's your call. I assume you want to use it on the 24-105 with a 2.0x (you lose autofocus with that, and it becomes F8 basically with manual focus, just to achieve 200mm basically, which is fine for landscape and all, at F11 or so, but not good at all for whales or puffins and the like; I'd just suck it up and take the 70-200).

Whales are actually best in the summer months in Iceland, so if you're going to be near the waters, you will have opportunities likely. Makes a case for the 500mm. I don't think the 50-500 is all that big personally, but it's your trip & opinion, but I'd want it for the whales on full frame. On APS-C, a 300mm would likely be fine. You could probably get away with a 70-200 on full frame for whales if the boats are close enough--but that's a big if.

If you still have an APS-C, you could take your 6D + 24-105 for the every day, and use an APS-C + 70-200 for the chance encounters with whales and close range puffins. Otherwise, I'd just strap the 50-500 onto your camera with a monopod. I think it's worth it, if photography is the point of the trip, since you are going in the prime months for species that are there.

Very best,

I went to Iceland (albeit in the late fall) and basically used my 24-105 (I subsequently upgraded it to 24-70 II) pretty much the entire time. There were a few vistas and waterfalls where the 24mm was NOT wide enough and I resorted to stitching multiple shots together. I would be remiss to mention that I did not get any decent shots of even sheep or horses since they kept running away as soon as they smelled me coming.

Other than that one time I went chasing after the sheep like an idiot, the only time I was lacking reach was when I wanted seabird shots.

OT Racer.
I am heading to Iceland this month.
I will be taking my "Greek Trilogy of the Canon f/4 L IS"
The 16-35 f/4 L IS, 24-70 f/4 L IS and the 70-200 f/4 L IS, all paired on a pair of Gripped 5D Mark III's. Heavy for sure but lighter than taking the 70-200 f/2.8 L IS Mark II.
I could slide in the bag the 1.4 Ext III if I feel the need.
After returning from two trips in Italy were f/2.8 was needed, I have the option of carrying around a smaller lighter 70-200 f/4 L IS in a smaller lighter package.
