I know everyone here is enamored with their new GF! cameras but I dont think I plan to go there.
I have an EP-1 and I am having fun with it and really like the built in stabilization. I took some pictures at an audio club event (another expensive hobby) the other night and while they werent the best I have ever taken they were acceptable and all with the 17, 1600 ISO and an average speed of 1/15 of a second. Other than lusting after the new 20mm I am happy with my results.
However (always an however) I dont find using legacy lenses are fun with the Pen as the screen resolution seems lacking for this use (not knocking it as I love the wide viewing angle, etc) and the camera is virtually useless in many low light situations as the lack of a focusing aid makes focus lock very problematic.
I have an E3 I can use but I really like carrying a camera with much less weight and I am thinking of selling the E3. From all the praise I have seen the G1 looks like a great add on to my collection. Its obviously much less expensive than the GH1. What, if anything do I lose (except video which I dont use on the EP-1) would I be missing with a G1 versus a GH-1? Have I waited too long to buy a G1 (grin)?
