I've got a lens related question about the GM1 and its 'Tele Converter' option. I've got the 12-32 kit zoom and a 14mm f2.5. I favor wide lenses for my job. For fun I take pictures and videos of my family, often in low light. Personal photos are mostly viewed on a screen and never printed bigger than A4. To avoid unflattering photos, I like to create some space and zoom in. At 32mm, this results in a F5.6 and is often too slow. Correct me if I'm wrong, but if I used my 14mm and the Tele Converter option (with size set to S), I get 28mm and keep f2.5 with much more useful shutter speeds. I lose OIS, but that doesn't help with rambunctious toddlers anyway (that would be awesome though). Is the unflattering affect of a wide angle lens a product perspective when you're really close to something? In David Thorpe's book about the GM1 controls, he says the camera uses the entire sensor and then downsamples. What's downsampling? The obvious drawback is that the image will be smaller (2272x1704), but do I lose a lot of detail as well? I guess I'll have to judge what's acceptable for how I use my photos - small is better than blurry. I'm wondering if the 14mm is worth holding on along with the 12-32. If the tele converter operates like I think, I'll probably keep it and get the wide angle adapter as well to stretch its usefulness out even further. Or maybe I sell it and get the 20mm F1.7... thanks!
