Rear focusing group makes focusing more than comfortable. That is what I love on this lens but then here is CA which could be really annoying. If you shoot mostly bw film like me then you could live with that. There are situations when it not so visible and there are such situations which are not so torture for this in the end beautiful telephoto. Try to be carefull and this glass will makes it very well.
