Telezoom with good IQ?
Jan 11, 2013

I've two Panasonic G1s which I use for cycletouring because of their lightness, with standard, 45-200 zoom and a 20 f1.7. Apart from the fact that they're no good for action, which I don't mind at all in this case, there's one problem.

My 45-200 is very good up to 150mm. Above that the IQ is poor at every aperture with CA, loss of sharpness etc.

Is there a telezoom with good performance throughout its range?
