<p>I found a solution on Adobe Forums. Apparently this problem goes back for at least updates during the past year. If anyone else has this problem, look for a posting titled "Lightroom CC (2015) does not recognize lenses since last update."</p>

<p>Update - The problem is less serious than I realized, but still troubling. The lenses for the D810 are listed as "Lens Unknown" when I filter images using Metadata. That hampers search, and also keeps me from looking at the total images taken with each lens, or looking at the number of images I have given high ratings to with each lens. <br> This something I would not have noticed if I had not searched the Metadata for images taken with a particular lens that I am considering replacing.<br> Greg</p>

<p>Hi - I installed the latest Lightroom CC update 10 days ago (automatically through Creative Cloud). I just opened it today.<br> I have thousands of raw images for Nikon D810 processed through Develop that included lens profile corrections. When I opened Lightroom for first time since then, it no longer recognizes the lens types for the D810 images (from Nikon 24-120 F4, 70-200F4, 85/1.8G, and Sigma ART 24, 35, and 50). It does recognize them for my Nikon D500 images and Fuji XE-2 images, and from earlier images with D700 and D800.<br> I checked and my software is up to date. I have used Lightroom for years and have never had a problem like this before.<br> I did not see a reference to this with a quick check on Adobe Creative Cloud Forums.<br> Thanks for any help you can offer,<br> Greg</p>

Mervyn, I use both a Nikon D800 and a Fuji XE-2. Apart from size, I find accuracy of auto focus one of the greatest advantages of Fuji. It should be even better on an XT1. In my experience, focus accuracy with static objects is more precise and consistent with the Fuji. For things that are moving, though, the Nikon autofocus is much better. But from what I have read, the new autofocus systems on the XT1 and XT10 are a lot better than my XE2 for things that are moving. Three thoughts about possible issues. First, Fuji autofocus seems much better in the S mode than the C mode. I sometimes knock the dial into C mode by accident. Second, the size of the adjustable autofocus area zone matters a lot. With a big zone, my camera sometimes focuses on foreground or background objects. So I always keeps the zone very tight, which works fine with static objects. Finally, I sometimes get out of focus shots when I try to focus on low contrast areas, especially in low light. In these cases, I either try to include some sort of high contrast edge in the focus area, or switch to manual focus mode which is surprisingly easy on the Fuji body.

<p>Gordon Laing at Camera Lab just posted a review on that web site. He was generally quite favorable about the lens, but found that the VR essentially did not work in the 1/80 to 1/160 sec range on two separate copies. (It worked well at slower and faster exposures, but essentially not at all in that range. He got better results with VR turned off there.) He found the problems so severe that his overall evaluation was Not Recommended, which surprised me because he seems to be a competent but generally positive evaluator of cameras and lenses. I have money on one, so I hope this is an isolated problem (although he got the identical problem on two copies) or one that can be corrected in a camera firmware update. Everything else about the lens seems very good, especially the idea of a (relatively) light weight way to get good image quality with a 300 mm lens with VR. </p>
