Brand new to the forum(s), and I have a question: I currently own a GF1 with the Panasonic 20mm f/1.7 and 7-14mm f/4. I am planning to upgrade to the GX1, but I’ve been stuck on lens changes and/or additions. My initial thought was to simply add the Panasonic 45mm f/2.8 to the existing lenses. This would give me a macro capability that I currently lack, and the fact that the Pany is supposedly not quite as much the portrait lens as the Oly 45mm f/1.8 is not my major concern (if I’m doing serious portrait shots, I’ll use my D300 and 85mm f/1.4). However, I was also considering selling the 7-14mm and replacing it with the Oly 12mm f/2, and adding the 45mm f/1.8. I think the 7-14 is a great lens and I’ve produced great shots with it, but I rarely shoot it wider than 14mm. So, what I’m considering is moving from this kit (GF1, Pany 7-14mm f/4, Pany 20mm f/1.7) to this one (GX1, Oly 12mm f/2, Pany 20mm f/1.7, Oly 45mm f/1.8). The advantages I see are a smaller and lighter overall kit than this one (GX1, Pany 7-14mm f/4, 20mm f/1.7, 45mm f/2.8) with little, if any, tradeoffs in image quality, plus a gain of two full stops on the wide angle and 1-1/3 stop gain at 45mm. Are there *any* limitations using the Oly lenses on the GX1? I’ve been looking, but I can’t seem to find any specific answers. Is there any other consideration I may have overlooked??
