I currently have the following kit for travel: Olympus E-P3 Panasonic 7-14 Panasonic 20/1.7 Panasonic 45/2.8 These were purchased in the early years of m4/3. Since then, Olympus have come out with a few sweet lenses. I was thinking of replacing the 20/1.7 & 45 with the Olympus 17/1.8 & 45/1.8. I'm not a fan of zooms. I'd only use one if it's outstanding, like the 7-14. Not really interested in focal lengths > 60mm. I prefer primes. Thoughts? What would be your ideal 3-lens travel kit to cover landscapes, architecture & portraits? Thanks.
