Sorry for awakening a somewhat older thread, but I purchased a Tamron 90mm Macro Di VC USD F017 for my D850 last week and tested it over the weekend. Fantastic IQ, probably the sharpest lens I’ve ...

Whilst being first to accept that my test methodologies may not be perfect in every respect and there are sources of variability, I try to always confirm focus calibration attempts with varied, ...

Certainly hope so. Returning lens today for a replacement unit, so we’ll see. I might have mentioned this already, but there are some reports out there of same/very similar AF inconsistency issues ...

Yeah, from my testing this weekend I definitely see the great potential of the Tamron 90mm SP VC 0017. Beautifully sharp across the frame. Kicks the stuffing out of my Nikkor 24-70mm zoom that's ...

I might go with the Nikkor now. After spending the weekend fiddling with the Tamron SP 90mm 0017, I can say it’s a fantastically sharp lens and works very well at macro distances. However my ...

Have even tried TAP-in now and does nothing to the AF inconsistency at longer focal distances. Unfortunately this sample is going back to B&H.

So now also tried adjustments using TAP-in. As expected this changes focal point bias, but does not resolve the inconsistent AF. Afraid this sample is going back to B&H. Shame as this is a ...

See here for thread where I post shots showing AF inconsistency with subject distance greater than 3m. https://www.dpreview.com/forums/post/62321385

So, now tested in liveview and AF inconsistency at >3m focal distance remains. Shot using tripod, 3s exposure delay with EFCS. Shots below are apprx 100% crops, focus point is the vertical bars ...

The test shots were taken with tripod, 3s exposure delay and EFCS, AF-S, single point at center. Lens focus limiter switch set to 0.5m to infinity, VC off. Will do more testing today.

I can give it a go, but like I said the focus at tele end is inconsistent. Sometimes ok sometimes bad. Lens calibration can only compensate for a fixed, repeatable error. Nevertheless I’ll try it ...

Yes, I’m using AF-S, center focus point only. I have TAP-in but it’s not going to help because the problem is inconsistent (variable) focus when subject is greater than 3-4m away. The focus is ...

Got my Tamron 90mm Macro 0017 yesterday, tested extensively today. Fantastic sharpness, bokeh, etc. Only issue is a portrait distances >3m or so. AF misses severely about 50-66% of time. AF fine ...

Hmmm, we’ll beautiful lens. Sharpness, nothing short of astonishing. No need for AF fine tuning. Only issue is that at distances greater than 3m, say beyond head and shoulders portrait distance, ...

Yes, Sharp. Heavy? Big? Not really. Here’s some taken on my D500, not full res (ability to handle flare is excellent)

Ouch! :-)

My Tamron SP 90mm macro [0017] is due to arrive tomorrow from B&H. Looking forward playing around and trying some focus stacking this weekend. Will be my first venture into world of macro ...

The way I read the article is that improved AF/AE and eye detect feature are only in store for the Z’s. D850 will apparently only get CFE compatibility and timing to be announced later in the year.

I heard from a more knowledgeable salesman in photo department at my local Best Buy that firmware update was planned to improve AF for the Z’s. First I’ve heard about possible FW update for D850, ...

Ha ha, I kept the box and packing materials Nikon used to return my camera for use next time ;-)
