Lens choice is very personal and heavily dependent on what you shoot. I'm lucky to have a few lenses in my kit - most of which i have acquired used. For me, I find zooms excellent for landscapes and general daytime use. If you do a lot of this, then getting a wide- standard zoom is the best initial plan.
You're absolutely right! My goal is to shoot some landscapes with the 12-40 @ 12mm; it was my first intention when I was planning to get the 17mm 1.8, but the 12-40 hooked me!
There is no shortage of choice for such lenses in the u43 world with everything from cheap kit lenses through to higher end f2.8 ones. Most deliver respectable performance but If you can afford it, I'd definitely say get one of the 2.8 variants - either the Olympus 12-40 or the Panasonic 12-35. There's very little to choose between them.
Yes -- I've read that the pana is smaller and lighter - I'm torn!
For non-studio people shots you'll want something with better DOF separation capability. The 45/1.8 is hard to beat at the price.
Indeed - My starter pack will be the 12-40(35?) + 40-150R, and with some more saving, as I'll travel November only, I'll be able to get the O45.
The 40-150 R is quite a lens for the price, but don't expect miracles from it.
I know, only for bright days and not wide open
