Hi first post. I recently joined the m4/3 bandwagon with the G1. Being a Nikon D300 owner I wanted something small & light that i could take with me all the time, either in a large coat pocket or a small bag, the Slingshot 100 being perfect for this camera. Well after having the G1 for a couple of months now im very impressed with it image quality, upto ISO 800 images are great, in fact even at iso 1600 isn't all that far behind my D300, but ISO 1600 isn't something i use alot & most of my shooting is done outdoors in good light. The EVF was something i was worried about but the quality is good it's actually superb using it outside and the view you get from it is massive, also being able to see the histogram in the VF is very useful. I've already invested in 2 more lenses, the superb 20mm F1.7 & the handy 45-200mm I already had the 14-45mm as that came with the camera. One thing i have to say about the 14-45mm is how good the build quality is for a kit lens, ie quiet, fast focusing, built in IS & the front end doesn't rotate Nikon standard 18-55mm IS lens pales in comparison, also the 14-45mm image quality is great aswell sharp with good detail & contrast, very impressive from a kit lens. Also i find the 20mm F1.7 being one of the best primes i used to date, the 35mm F1.8G, 50mm F1.4D & the 85mm F1.8D i have with my D300 doesn't even come close the 20mm.. this lens outperforms the lot of them. I just hope Panasonic release more primes in the future mainly a 40mm F1.4 for portraits, but also would love a wide angle one aswell something like a 12mm F2.0. Now onto the 45-200mm great lens ie give me 400mm, but i do find it slightly soft at 200mm but nothing abit of sharping won't solve in Lightroom, but build quality is good same as the 14-45mm & quiet focussing to. Basically i rate this lens easily a good as Nikon 70-300mm VR, but advantage being it's alot smaller & cheaper to boot aswell, im not really one for telephoto lenses, but the 45-200mm will come in handy at some point & images are sharp upto around the 150mm mark. It's got to the point now, were im actually considering selling my D300 kit as i've not used it since getting the G1 and using some of the money to fund the 7-14mm lens which going of what i've seen on flickr ect is another superb lens. Overall im very pleased with the G1, it does basically everything i need in a much smaller lighter take anywere package. Also looking forward to what Panasonic have got coming our way in the future with both new bodies & lenses.
