Sigma 50 mm f/1.4 Art

[Kayaker72]

I preordered the morning of the release, and all I have received is a notice saying that the 50A is backordered.

Anyone received theirs? Any impressions/photos to share?

From what I am reading and seeing on the web, this is a very nice lens but there are potential issues:

• There are reports of AF issues. Apparently the Sigma Dock is a must as setting a single AFMA value at one distance isn't enough. The dock allows you to set different AFMA values for different distances.
• Of course, AFMA is about accuracy, not precision. There seem to be precision issues, potentially similar to what Bryan noted. I've seen at least two reports where people are having perfect AF for a large number of shots and then, inexplicably, AF misses.
• Color rendition. Seems that certain colors are more saturated and I am wondering if others are less saturated.

Despite the above concerns, this lens seems to be making a very good impression with many and I've seen many impressive images. Of course, depending upon the severity, the above issues may be enough for me to keep my 50 f/1.4.

....or...the concerns may be much ado about nothing....

Great shot Sean

It will be interesting to hear your thoughts.
