woodland landscape and a close up Damselfly.
yup exif isDamselfly....handheld?
Nice pics. Just wondering if you'd checked for front/back focus as some of these shots seem slightly soft?
The Tamron can have focus issues but this does not sound like it,i know nothing about Canon cameras but did read in the early days of this lens some Canon cameras had a focus setting which to avoid wasted time it would not try or stop trying if it couldn't achieve focus,not sure which models though.
The focus problem is normally just a refusal to focus at any preset distance or focal length,then removing the lens and refitting or doing the same with the battery would clear it.
Thanks Mike, it does try a a bit to focus, i.e. it does move so far bus stops before it gets anywhere near so may be it is a setting that makes it think it is not going to achieve focus, I'll have a Google

Thanks Mike, I'll try it later
The best way to check if its related to the normal problem is next time dont touch the manual focus ring but try in this order,switch camera off and on then try again,remove and refit battery then try again,remove and refit lens then try again,if any one of those options makes it work the its possible its the freeze problem.
Was doing a bit of googling about this today and I read about a focus limiter, which had completely slipped my mind, must be getting old, but yes it wouldn't focus below 15m.
DOH!!!
Truly superb pics. I love the colours and tones in the first and last.Not much going on in here so I thought I'd post a couple of shots.

Three possibilities spring to mind:-Has anyone else had any problems with the AF on a Nikon D810?
I just can't get it to focus sharply - unless up closely, up to around 5 meters away - and have just emailed Tamron about a possible firmware update.
It worked totally fine, with no problems at all, on my D7100 and D600, just not the D810.
Three possibilities spring to mind:-
1: Firmware as you've mentioned
2: Needs micro adjusting for the D810
3: You need to increase shutter speed due to the extra resolution on the D810.
There are times when mine drives me wild in its refusal to find focus - even on stationary subjects.........
....that's on a 5d3.

Yeah, I get that too when the AF just freezes. It's a well-known problem though, so I just switch off the camera then back on again!

I've noticed this with mine, never known a lens get so much dust in it. Supposedly it's partially weather sealed tooAnd it's FULL of dust!
Having said all that the lens is capable of getting some excellent results.

Never heard of them, can you recommend any?I use one of those zoom socks to stop the dust getting sucked in
