Reddit mentions of Olympus M.Zuiko Digital ED 9-18mm F4.0-5.6 Lens, for Micro Four Thirds Cameras

I'd say go for a telephoto first.

That said, even though it is [on sale for $99] (http://www.amazon.com/gp/product/B0066J6EOU/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B0066J6EOU&linkCode=as2&tag=battleforthew-20), I recommend against the Oly 40-150 because it doesn't have image stabilization.

The [Panasonic 45-200mm with Mega OIS] (http://www.amazon.com/gp/product/B001ISKNKA/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B001ISKNKA&linkCode=as2&tag=battleforthew-20) will cost you more, but image stabilization at the long end of a telephoto lens is worth the extra money.

And, If budget permits, I recommend the [Oly 9-18mm] (http://www.amazon.com/gp/product/B0035LBRM6/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B0035LBRM6&linkCode=as2&tag=battleforthew-20) for landscapes. This is a very good value-for-money wide angle lens.

Hope this is helpful and best of luck on your trip!

I've got the Olympus 9-18mm f/4.0-5.6 and I've been super happy with it. I think the build quality of the Panasonic 7-14 is higher but so is the price, and while I'm jealous of the super-wide aspect of the 7-14, I think that the focal length of the 9-18mm is actually a lot more versatile since at its most zoomed it's basically a 35mm equivalent.

Unfortunately it looks like zoom wide glass for your particular camera is crazy expensive. If you had something like a Canon t6i a 10-18mm would be 300$

Here are the lenses I was able to find, it doesn't appear Rokinon or Sigma offer a zoom lens suited for your needs.

Hi /u/fantastictransistor - congrats on the upgrade from the T4i to the GH4! I switched from the T2i to GH cameras a couple of years ago, and it was the smartest camera decision I ever made.

You've gotten several good suggestions here - but it really boils down to how much money you want to spend, whether you want an auto or manual lens and whether you need a fast lens for low light. Here are your options, ranked from most expensive to least expensive, with some of the pros and cons of each [Referral Links]:

• [Panasonic 7-14mm - $968] (http://www.amazon.com/gp/product/B0028Y5GKK/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B0028Y5GKK&linkCode=as2&tag=battleforthew-20) - awesome native wide angle lens - but it is expensive, and slow at f4.0. You may want to look elsewhere if you need a low light lens.
  
  
• [Tokina 11-16mm f2.8 for Nikon (old version since you won't need the quiet autofocus motor on the new version) - $471] (http://www.amazon.com/gp/product/B0014Z3XMC/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B0014Z3XMC&linkCode=as2&tag=battleforthew-20) plus a [$429 Metabones Nikon G to micro 4/3 Speed Booster] (http://www.adorama.com/MBNGMFTSB.html?KBID=66297) - this option will give you the equivalent field of view of an 8-11mm f2 lens for less than the price of the Panasonic 7-14mm - but you'll have to focus and set your aperture manually.
  
  
• [Olympus 9-18mm f4-5.6 - $649] (http://www.amazon.com/gp/product/B0035LBRM6/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B0035LBRM6&linkCode=as2&tag=battleforthew-20) - this is a great budget wide angle lens for micro 4/3 cameras, but again it is slow. At the long end, it is even slower than the Panasonic 7-14mm.
  
  
• [Rokinon 10mm T3.1 for Canon EF mount - $530] (http://www.amazon.com/gp/product/B00K3T3MCG/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00K3T3MCG&linkCode=as2&tag=battleforthew-20) (as of this post) - plus a [$94 third party focal reducer/speed booster] (http://rover.ebay.com/rover/1/711-53200-19255-0/1?icep_ff3=2&pub=5575034783&toolid=10001&campid=5337235943&customid=&icep_item=281240980971&ipn=psmain&icep_vectorid=229466&kwid=902099&mtid=824&kw=lg) - if you don't mind shooting with a manual prime lens, this will be your least expensive option and will give you the equivalent of a 7mm f2 lens - the fastest and widest you can get in micro 4/3 without the "fisheye" effect.
  
  Hope this is helpful!

What do you think about the Oly 17mm f/1.8? and what is your recommendation for wide angle zoom or prime? There doesn't seem to be a large selection. Maybe it's difficult to make wide angle lenses for m4/3?

I see this Panasonic and this OLympus. Both are much more expensive than the Canon wide angle which can be had for <300.
