Have gotten a lot of help from many good contributors in this forum with regard to the 58. I just received mine a few days ago... seems I am about 4 years late to the party. Anyway, one really helpful thing has been many of the images posted here. Also, as a side note, I have noticed how the postings--by the time they go from computer through to thread--get diminished a good bit (just an FYI to all). I say this because I just put the same images I'm linking to here on Flickr, on other sites, and I noticed the "zoom-in" view on Flickr is MUCH sharper (like my original at 100% on my computer) than others I have posted in other places.
Anyway, here is a link to some images I took the other day with the 58, and I was trying to take them in unfavorable conditions, most anyway. They are wide open, on a D800e, 6400 ISO. Link:
