Hi i have been using the Panasonic 45-200mm for a few days and whilst it is quite good (though still a bit hit and miss) before 150mm, the image quality seems significantly worse after 150mm. So I am thinking what is the point of a 200mm lens that I will only use up to 150mm?? I am using this on a E-PL1 and for stills not video... Landscape, architecture details, people. I tried the m.zuiko 40-150mm but was not that impressed, maybe I needed to be more patient, so might swap it but was also wondering... Has anyone used the Olympus four thirds 40-150mm and an MMF adapter - is the IQ any better than the 45-200 or the M43 40 -150mm? I am happy with a slower AF if the quality is better. Are there any other alternatives? (other than manual lenses) still searching for that perfect lens!! Thanks for your advice..
