I contacted Tamron to ask about the issue and they replied as shown below.
I must accept what they say to be true unless someone can advise differently.
So it appears I don't really have a problem.
Thank you all for assisting.
(Please see below their reply)
Dear Charlie,
This is normal, with a macro lens the maximum aperture is (2.8) when the lens is focused at infinity as you focus closer the lens moves further from the sensor which spreads out the light and makes the image darker. The effect aperture is reduced even though the physical aperture has not changed, until at 1:1 you have lost 2 stops, this is known as bellows effect (The light that passes the lens is diluted to a bigger area),this is physics not a problem with the lens.
These 2 links will give you some additional information. https://www.cambridgeincolour.com/forums/thread1358.htm and
https://www.dpreview.com/forums/post/61281835.
Let me know if you require any further assistance.
Regards.
Nigel.

Thank you all.
It is the newer SP model.
When I attach the Tamron 24-70 G2 the Aperture priority, I can always set it to f2.8 and higher.
But when I attach the new 90mm SP it does not go down to f2.8, just now it went to f3, earlier it went down to f4 only. So it appears to be intermittent.
I have tried focussing close to minimum and also further at 1m and further again.
Still cannot get it to go down to f2.8.
Help?

Hi all.
I recently bought a new Tamron 90mm G2 f2.8 macro lens.
When set to Aperture Priority, my D850 sometimes does not go down to F2.8.
It can be wound down to say F4, but no lower.
I have tried other lenses to same settings and have no problem (for example using the 24-70 G2 I can set it to f2.8 no problem).
Has anyone experienced this type of thing with that lens?
I am stumped as to why I cannot get the maximum aperture out of this lens particularly when shooting in low light and close up.
Any thoughts would be appreciated.
Thank you.

Thank you all for the information.
I think I will get a 10x ND.
I am thinking one of the following:
B&W MRC 110 F PRO
B&W XS PRO MRC NANO
Breakthrough X4.
There are so many to chose from any further guidance would be appreciated.
Thank you all again.

I love this forum and hope you can assist with info on the following.
I have a D850 with a Tamron SP 24-70 G2 lens.
Off to Croatia soon and my friend said there are waterfalls to photograph.
I am looking at buying an 82mm ND filter for this lens, Hoya, Kenko or B&W.
My question is, do I get a fixed ND filter or a variable filter.
Will a variable ND filter set to minimum have a noticeable reduction in sharpness or quality compared to a simple UV filter when taking general landscape shots? I am thinking of leaving it on even when it is not needed and shoot normal shots then setting it to the highest ND value to take waterfall shots..
Alternatively I would just buy a good quality ND 10 screw on filter and attach it when shooting waterfalls.
I hope you understand what I mean and can assist in advising on quality differences between the two options. The aim is to get that soft blanket effect of the water whilst keeping the rest sharp.
Hope you can assist.

Yes that would work.
You would need to deposit into my account before shipping.
I think shipping from Australia to USA by Australia Post Express is about $125.00 AU with packing box.
Thank you.

Hello to all.
I just received my D850 last month and love it.
So my D800 with about 52k shutter usage is now for sale and want to ask if there is a place on this forum for selling equipment? I looked but not being IT savvy could not really see anything that suggests there is an equipment for sale section.
If not would anyone have a suggestion that may assist me.
I am in Australia (Bne).
Any guidance would be appreciated.
Thank you.

Hi everyone.
I love this site, lots to learn from you all.
I just got my D850. My question is about a suitable programme for stacking the Focus Shift images into one.
I currently use DXO Photolab and love it, I also have Corel Paintshop Pro 2018 and use it very seldom.
My question is what is a good software for stacking landscape images which I take with the D850.
Can you use the Raw files to create a new raw file and then be able to further process afterwards using the DXO software. I am not sure if you need to process all the Raw files first then use the Jpegs in the stacker program. I tend to process my Raw files using the DXO and love the changes I can make to end up with a great looking photo. I am concerned that once you stack Raw images you wont be able to process to the same degree.?
Any clarification would be appreciated.
Thank you
