Rumored Image of OM System 50-250mm F4 Lens Leaked

This is just an expected image rumored at 43, but with a zoom of 250mm (500mm equivalent) at the telephoto end of F4, this size seems to be quite easy to use. From the image, there is no “PRO” on this lens? we are also curious if this lens will be an inner zoom or if it will be extended.
