A well constructed lens and possibly reasonable in it's day. Image quality is let down by very poor contrast which requires significant work in photo editing software to get any where near usable. Not the sharpest either. After stripping mine down to investigate further I've found one of the inner reflectors to be misty, which could explain the poor contrast. Not sure if this a common issue. I'll see if it is possible to clear this misting and if so post a further review.
