Most windows drop, check it before you sit down. And they always stop for animals if they can. I take glass wipes with me for cleaning plane windows when I travel. Small planes always get muddy windows, definitely work for bus windows along that dirt road.

Your Tamrons will cover everything you'll encounter. G2's work very well in wet environment. The Canon 10-18 is a great lightweight addition. If you do any hiking on forest trails or walking in town you can get some incredible opportunities to give it a try. I carry my 150-600 g2 everyday for work and use it often. Skip the 1.4 or rent it for the trip to try it out. I didn't like it with the 150-600. Save the money and use for Tamron 18-400, it would do well for your trip or sometime later; not changing lenses is nice. If you have a lightweight mono I'd take that, I use mine all the time. Works excellent with your 150-600. It can make an incredible focus difference in a once in a lifetime shot. You're going on a cruise not mountain climbing so you can take what you have room for. Take extra sd cards, you'll fill them up. Take at least 2 extra batteries. It's so disappointing to run out of storage or power when action is fast. Bring lens drying materials. All your gear will get wet. Alaska is an endless photo opportunity from macro to the Aurora. Lots more than just scenery and animals. If it's raining and foggy you can still finding amazing things to photograph. You can easily shoot over 1000 per day. A trip to Alaska is an incredible photography learning opportunity. Hope you have lots of fun and make some wonderful memories visiting our home.

Lol, beautiful shot of an ugly critter. Nicely done!

Nice shot Mike. I like owls as well. Tough to spot sometimes.

Welcome to UHH. Some incredible photos are taken with phone cameras. Thanks for sharing.

Nice shot Mike

Nice set. I like the color you captured in the first one.

[quote=kashka51][quote=tims.ak]I use Lacie, they make HDD and SSD versions. SSD is nice but I haven't had a failure on my HDD and I travel with it every week.They come in a rugged colored case so you won't misplace it.

There are several other types out there. Just be sure to get one with a battery source or you'll need external power. Most of them also work for a backup charge for your phone or other device.[/quote
But does it have a sd card slot?[/quote]

It does come with SD. There are several other brands with with SD slots for direct transfer as well. They also have a newer model with micro sd. If you just want to transfer without a computer make sure to read description and reviews. Lots of misleading info about portable drives.

Take a look at LaCie. They've been making portable rugged drives for several years and seem very reliable. They have different sizes, versions and prices that might be what you need.They use Seagate drives and come with data warranty. Not sure how reliable that service is as I've never needed it. I travel with mine around rural Alaska every week, it gets banged around and moved between travel bags. Maybe lucky but I've never had a failure. They are sold at most major retailers. Maybe you can find one locally to take a look at. They have some new versions that are even better. Someday I'll replace mine with SSD version. Hopefully before failure. Have fun in Hawaii.

Wow, what a beautiful set. The second one of lenticulars is spectacular. Thanks for sharing.

From the cards you have now I'd recommend at least 2 more 16 GB cards. If your camera will take 32 GB I'd use them. They don't cost much and should give you some storage room. If you have another storage medium for transfer one extra might be enough. You never know what you might come across on a cruise. If the weather is cloudy and rainy it may change the focus of your interest. However there are lots of things to see in the towns you stop at. Last week while out fishing we encountered a pod of Orcas eating a humpback. You could fill a card very quickly with that type of encounter. It's very easy to rack up 1000 images or more per day when there's lots to see. SD cards are so inexpensive now, never go wrong having extras on a cruise to Alaska. Hope you enjoy our beautiful state.

Hahahaha, nice one. Good thing he didn't sneeze.

I carry/use the G2 version with me everywhere I travel. I mostly use it hand held and brace against rock piles or trees to stabilize when needed. I do travel with a Sirui mono and tripod and have had no trouble using either of them with the lens. The mono works great shooting from a vehicle. It quickly adapts to whatever height. At 6 lbs I find the camera/lens balanced very well, easy to carry and use. For something lighter you could try the Tamron 18-400. I carry it also, it's much lighter. Not the same for birds or wildlife but it works well for most opportunities. Or as you.mentioned pump a little iron and try it longer. Might take some adjustment time lugging it around and figuring how to adapt it to your shooting preferences.
