I read an article once by Roger C. from LensRentals where he talked about the fact that very small manufacturing variations in the body (lens mount, etc.) and lenses can produce exceptionally sharp pairings or bad pairings. I wonder if that is at work here. Honestly, your samples don't look very good to me, and at F8 on a tripod you shouldn't see much to complain about.
My 85 1.8G is really sweet on my D300s. (a handheld pic that isn't up to this thread, but is super-sharp when looking at the file - not sure Flickr does it full...Show more →
Thanks for the feedback. I've read Roger's article as well. Actually, I've read dozens of articles (perhaps 50 or more) on focusing, fine tuning, etc. At this point, I feel I have a pretty good understanding of where things could be going wrong for my D800 and this 85mm 1.8 lens. None of it seems to apply to me exactly as my results seem to be inconsistent.
I would happily accept that this copy of this lens doesn't work with my D800, except this is actually the second copy of this lens I've had. The first went back right away as it was measurably bad and could not be fine-tuned into acceptable focus. Is it possible I could have received two "bad" copies in a row? Yes, but it's highly unlikely.
This second copy is better--much better even--but I'm unsure if it's "good enough." I've fine tuned using different methods, tested it in a plethora of conditions and reviewed my photos at 100%. The results leave me wanting more. I can get a sharp image with this lens, but my "hit" rate is really low (perhaps 2%).
I find myself frustrated and fighting to find sharp photos with this lens. To give myself a break from all my testing, I popped on my Nikon 50mm f/1.8D for a few minutes: 10 shots, 8 sharp. Felt good.
Here's a photo I took yesterday with the 85mm f/1.8. It is probably the sharpest I've taken with it yet. When you consider I've taken more than 1,000 frames with this lens, it's not really the best news. All in all, I'd say my 85mm 1.8 can achieve sharp focus, but it's extremely difficult to get it there and often inconsistent.
At this point my period for evaluation is almost up. My return by date is a couple weeks, but I don't know what else I can do to test it. I left deciding if I want the focal length at the cost of a low hit rate, or simply accept my D800 cannot handle longer focal lengths due to its front focusing and return it for a refund.
