Wide angled lens for mountains?

I have not read all the posts.

SO,

depending of where you will physically be with the camera/lens and said mountain even a telephoto lens could be better than wide angle. I would know that variable and look at telephoto.

OR

Look at a p&s camera that has a wide angle lens range and get a telephoto lens for your MFT's camera.

OR

really travel light and do something like a bridge camera, Canon GX-3, Sony RX-10, Panasonic FZ-1000

Just think about what money you are ready to spend on a lens vs other options to think outside of what you have.

It is also important to know that if you buy a new camera or lens to cover what you need will you still use it after your vacation for other things. How practical is it. If it is a fisheye lens will you really use or need a specialized item like that for a arbitrary example.

*Last, this could be the time to revamp your MFT's lens set up all together and sell your 14-140 and get a fast 2.8 wide zoom like the Panasonic 12-35 mm 2.8 or Olympus whatever if you rarely use the telephoto range of said lens.

Their are many options and sometimes the p&s or bridge camera etc, makes more sense for versatility after the fact for sake of a vacation. That is not to say you can't bring your Olympus and a second camera. My taste is depending on the destination I may take a P&S and my main camera.

I forgot:

Think about if you will use or need filters for landscapes etc.. IF so forget my p&s idea. Look at the LEE Seven 5 filters, It is not inexpensive but a idea specifically for landscape that is very versatile IMO.
