The DPreview galleries tend to butcher any images making anything beyond composition hard to determine.

I find that the "original" version at the largest size looks good without the DPReview image quality tax applied.

The largest size seems to be 1024pixels wide which certainly does not allow for any critical determination of sharpness or detail . I like the composition and choice of B&W for the subject

Jim: try this out. I think it is about a 66% crop or so.

You can see that the zone of focus starts to get slightly blurry back at the ears and at the top of the shoulder. There seems to be plenty of sharpness at the eyes. [Note after posting: the full-zoom DPreview-rendered version is slightly less critically sharp and contrasty than the Lightroom-exported JPEG on my computer. Oh well.]

I wasn't doubting you Rick ,I have the 45mm it’s a great performer and I expected the original image to be exactly as you described it. My only comment was regarding the DPreview image hosting which can really suck the quality out of a posted image , I have exchanged original images with folk on the forum and the difference can be staggering. Apparently they improved the gallery when they improved the forum that worked out great.

That's OK, I figured it was better to show rather than tell anyway. The DPreview image hosting in this case does not seem horrible (as long as you click to enlarge), but it is certainly not 100 %.
