[QUOTE="snerkler, post: 668882, member: 44852"] I've already contacted Tamron and their response didn't fill me with the greatest of confidence. They referred me to page 95 of the D850 manual saying that only limited AF points are available with f4 lenses and beyond. If you've seen the manual you will see that that's only some very specific F4 lenses, and for Tamron to think that the D850 (or any modern camera's) AF points only work with f4 lenses and wider worries me a little bit TBH. That's great, thanks for that I appreciate it. What AF mode did you use, single point, group, dynamic etc? I don't suppose I could trouble you further please? Do you use Lightroom and if so have the AF point plugin that shows you what AF points were used and able to post a screen shot of those please? Sorry to be a nuisance. [/QUOTE]
