I have had the 50 makro. If I didnt own the Otus now I would just pickup anther 50 f2. Problem is I really don't need the otus but like owning it. The makro is so much more practical in size. but the otus delivers such outstanding results. I would not recommend the otus unless you need that level of performance. I just happen to have been fortunate enough to get one of the first ones and am not willing to part with it. I may put it back in the box and shelf it for a while. However, I will say, I will probably use my 50mm 1.4 AIS more often now because of size.
