    Cons: manual focus, heavy for my taste

    Pros: very sharp, sharper than fujinon 35 f2 and very simular to fujinon 50 f2, better colors than fujinons, blue sky is better compared to fujinons with polar filter, f1.4 is sharp too

    Summary: You can bye it after reading this review, if you can live without autofocus it is your lens !!!!
