I would stick with your 18-135 and add wider is even better. Think the 10-18 will do nicely for your trip. ND or CP filter may help also. Sounds exciting. Best of luck.

We were at Machu Picchu several years ago. I suggest the following: 1. Get a Tamron 18-400 Lens which is on sale at B&H for $599. You won't need any other lens. 2. Carry a back up camera even if it is a good pocket camera. I have had cameras fail on trips and now always carry 2 cameras. 3. When we were there, on a tour, the only food was a buffet. We had 3 or 4 people get food poisoning. Be very careful of what you eat.

that's about right, For most of my trip 2 mos ago, I just had my 24-85mm on my D610.
Plan to stay at Cuzco a few more days, it is a very interesting towns and a hub to visit surrounding towns/ruins of the Sacred Valley.
Buy the morning session ticket for Machu Picchu and you can stay till it closes, nobody check ticket on exit.
Don't hang your camera set onto your neck unless you want a sore neck; I had mine hung on to the straps of my backpack.
For wide angle, shoot a few for panoramic stitching is better than a fish eye view.
If you have the chance, visit Rainbow Mountain(17,000ft). It was a long way hiking up. I had to stop every 3 mins for half min because of the thin air and I experienced a hail storm at the summit.

Very spectacular.

AzPicLady Loc: Behind the camera!

I used my 28-135 exclusively at Machu Picchu and Pisaq/Cuzco. I haven't been to the lake, but I'd use the same lens, likely. In my younger days, I'd have carried my 28-300, but it has gotten too heavy for all-day carry.

Use the space and weight in your backpack for snacks and water!

It has been a couple of years since I was there. I hear that in Machu Picchu now, the trigger is s tripod. I carry a monopod that doubles as a walking stick, so I've never had a problem.
