Well, after really loving the Panasonic 12-35mm zoom, I decided I'm going to take a further step and get the 35-100mm. This means some other gear will be for sale and it will be my Oly 75mm f/1.8 and the Panasonic 45-150mm f/4-5.6. Both are great lenses, but I can make do with the 35-100mm and in fact I need that. I shoot some pro-bono events for churches from time to time and the zooms would be nice to have. I was shooting an event in my church yesterday hovering around ISO-3200 with the 45-150mm at full zoom and not all that happy. Two stops faster (fully zoomed in) would have been nice to have. Is the 75mm sharper? WAY sharper. But lens sharpness still isn't the most important criteria for me. Adequate sharpness, yes. Absolute sharpness (which the 75mm approaches) no. Certain qualities of the rendering are more important and it appears the 35-100mm will give me that. My kit shrinks to: 7-14mm, 12-35mm, 35-100mm, 17mm f/1.8, 25mm f/1.4. I like that actually. So: my kit evolves some more. I've moved back into my old ways: lesser bodies that I like and "pro" lenses. Likely I'll miss the 75mm but I need to at least mostly fund this purchase. I did find a 35-100mm from a reputable dealer in Japan for around $1100 shipped. THIS IS NOT ME OFFERING THESE FOR SALE YET. I will put up a classified when the time comes.
