Hi new to the forum I currently have a G3 with 14-42 kit lens which is adequate for most situations, but I'd really like a couple of lenses that will offer significant advantages over the 14-42. I received a Panasonic 45-150mm telephoto today which is an excellent lens, but I'm not sure it's something I need or will use much right now, so I think I'll send that back to Amazon. That leaves me with the short primes. I have £500 which will cover the 20mm 1.7, and the 45mm 1.8 - though I'm unsure as to what they offer over the standard kit lens? Obviously they are faster and sharper, but is the difference that marked? Are there better alternatives? One final question - should I keep the 45-150 and just go with one of the lenses listed above? It's a good lens, but would the 20mm be better for me at this point in time. Most of my photo's are landscapes or family portraits.
