Ok, When I returned the Sport to the seller, I said I would find out how his lens was fairing after it's first return from Sigma service, apparently this time with accompanying images Sigma looked at it again and indeed found it was de-centered, they promptly returned to Japan being unable to repair it in France!
The Tamron "Tapin console" to give it their "posh" name for it, arrived yesterday and I just plugged it in to the lens, it recognized the lens and displays four categories:
First off the Firmware was up to date when I clicked on it.
1; AF: 150/200/300/400/500/600mm at three distances 2.2 mts...20 mts...Infinity from-20- 0 +20 (can't find infinity symbol JoJu!)
Mainly the AF is accurate but I noticed a small back focus (I think) at about 50 mts @ 600mm so as a starting point I dialed in -1 at infinity.
2; Focus limiter: First position; is factory set.
Second position;.adjustable from 2.2 to infinity....I chose 5 - 10 mts;
Third position; adjustable from 2.2 to infinity... I chose 5 mts - infinity. Very useful!
3, Manual focus override sensibility;
From: low---0---high. (I didn't touch this setting)
4, VC Shutter/ viewfinder priority.....Standard......Viewfinder priority.....Capture priority.
This section is not so clear as the third choice is greyed out...so unsure at this stage I left it in standard.
Some AF and other settings are greyed out according to the lens used.
It requires an internet connection to make any changes to the settings so unless you can find the internet wherewithal you might as well leave it at home. it connects quickly and any changes are made before saving the settings, these can be done one at a time to avoid confusing programing, the process updates the lens in 15 seconds. I left the D500 AFFT (-2)set in the camera as it's different from the D750 (+2) and console changes will pivot around that.
The G2 basically has pretty accurate AF and not wishing to scramble my brain I shan't do a complete AF recalibration, but will modify any settings as and I go.
