Found where I read it, http://www.dpreview.com/forums/thread/3386481?page=4#forum-post-50922834

"
Someone on my FM thread recently discovered that the VF confirmation range increases dramatically when AF is set to MF (on either body or lens) vs leaving AF enabled and using back-button focusing as a way to avoid triggering a lens refocus when checking for VF focus confirmation. I always use back-button focusing when I DotTune but I told everyone in my video to disable AF because I thought is would be an easier procedure for those who aren't already familiar with back-button focusing. I failed to test that step before describing it to others, sorry!

When I toggle AF/MF I see an immediate change to the confirmed range. Here are the results of a DotTune with AF enabled vs AF disabled:

  • AF enabled: -14 to -18
  • AF disabled: -2 to -20 (past end of -20 range)
My theory is that Nikon's firmware is intentionally expanding the in-focus range for VF confirmation (when AF is disabled) to make it easier and faster for photographers to manually focus. They probably figured that if the range were tight it would be too difficult and time consuming for people to manually focus to it.

So here is an important update to the DotTune method described in the video:

  • Configure your body for back-button focusing by setting "AF activation" to "AF-ON only". On this D800 this is option a4
  • After establishing critical focus of your AF target, leave the body and lens to set AF rather than switching to MF
  • During the DotTune VF range-discovery procedure (step 4 and 5 in my video), use a half-press of the shutter to turn on the VF confirmation. In my video I said you could use either a half-press of the shutter *or* the AF-ON button, but now that we're leaving AF enabled you must use a half-press of the shutter.
Note that when the body+lens are set to AF the VF confirmation display wont stay illuminated for the duration of the metering timeout like it does when the body or lens are set to MF. This means you have to hold the shutter half-pressed to keep the confirmation display active while checking for the dot."

So I tried this out of curiosity today and the range does indeed reduce considerably using BBF.

One very perculiar thing I noticed today though was that the results during the Dot Tune method varied considerably with VR on and VR off. With VR on MA is +12, with VR off it was too far off the scale to get a reading. The first constant dot was +18 and was still constant at +20. Strange thing was that shots are sharper at +12 than +20 regardless of whether VR was on or off. I repeated the test a few times to make sure it wasn't user error.
 
Bit the bullet and ordered the DTSE grip off ebay, utilised the 20% off promo.

**** pretty sure I left the VR on but as on a tripod should have been off I suppose ( anyone read the manual?) Mine came out at +6 and +12 so set it at 9.

Yep VR should always be turned off. That being said with mine turned off the results were wrong IMO as mentioned above. Very odd.

That's a bit of a wait, where've you ordered from?

Ordered through Onestop Digital. Friend of mine is currently in Hong Kong on business and has kindly agreed to bring it back for me. They have a shop front, so cash deals get a better discount.
 
Brand new 24-120 in classifieds, lens is not for me.
 
Did see that, but doubt you would sell at the price I've got it for
 
Has anyone ever bothered to send their camera and all lenses off to Nikon to be calibrated? Is so what sort of cost is involved and what's the safest way to ship all the gear?

On another note, I think I'm finally going to get around to installing the latest firmware on my camera, did I read somewhere that you can save all of your user settings before updating and then reinstate the settings afterwards? If so would anyone care to share how to save me rummaging through the manual please? ;)

Edit: ignore this last bit, have found how to save and load settings. Does anyone know if it saves the lens MA's as it doesn't say in the manual although it does say it saves all non-CPU lens data which seems a bit odd?

Are you having fine tunes issues? Which lenses are affected?

Eeek: bit the bullet and just bought a D750. Also have an 85mm f/1.8g arriving next week, hopefully to coincide with the arrival of the body :)

I'm not jealous at all [emoji14]

Ps hope you left some over for Mrs pjm1's sweetener!

I tried suggesting she takes my old Pentax out but she wasn't up for it. We're off to Arran in a week's time and I can already sense an "upgrade" to a better hotel coming :(

Ah, just like the time he buys another car so I get to buy a piano. Not quite a balanced deal, really. :P

I must check out the serial no of my new 750 incase it is part of the latest recall and if it is, my 70-200 is going back along with to to be calibrated. I have never been that happy with the sharpness of of, i did MA it with my D7000 but haven't had time yet to do it with the 750.
 
Looks like I'll be waiting ANOTHER 7-10 days to get my camera back. WTF??? They get deliveries once a week from Nikon. Even though they knew it needed a new screen last week, they didn't order it until Tuesday... So it won't arrive until next Wednesday then they have to do the repair, then send it back...

Fab.

All my lenses barring one need fine tuning, but my 70-200mm is baffling me as it seems to change every time I put it on, and also differs with VR on to VR off. Test shots also conflict with real world shooting. With VR off both Dot Tune and graded lines at 45 degrees would suggest that it needs +20 or more, but to get the sharpest real world shots it needs +15 with VR off, and +12 with VR on. This is one of the reasons that I'm going to do the firmware update to see if there's some weird gremlin that sorts itself out. Also, when I send it in for the shutter issue after the Marathon I'll ask them to check the AF module (risky I know). Failing that I'm tempted to send in my lenses with the camera to be calibrated, I just don't like the idea of sending my 70-200mm through the post, and imagine cost with insurance will be hefty :( Obviously I'll not be able to send my Tammy or Siggy in though.

Off the top of my head:-
70-200mm f2.8 +12-15.
24-120mm f4 +2
50mm f1.8 +18
Tamron 150-600mm +5
Sigma 105mm f2.8 macro +6
18-35mm f3.5-4.5 0

That's a very big premium just to get VC/VR on that lens (versus the Nikon). That buys quite a lot of tripod, L-bracket etc ;)

It is, and quite a bit of extra heft too. Weighs as much as an f1.4 :eek:
 
Not a D750 owner anymore:( sent it off for part-ex against a D810 and it's just arrived, couldn't resist with the current deals. It was a GAS thing and not a need, as I wanted one when I came back to Nikon from the Fuji XT1. Managed to pick up a minty, like new, 80-200mm f2.8 lens for me to try out, hope the weight won't be to bad when shoulder surgery has fully healed.

I hope you shot that with an ultra wide angle and it's just perspective distortion... otherwise that GIANT SD card ain't gonna fit in the slot ;)


(sorry, silly comment but I don't understand why they put them in such disproportionately large boxes!?)

It is a lot! Especially as the 85mm is just over £300 grey! Maybe I shoudl try the 35/85 combo again.... for the 3rd time :LOL::LOL::LOL:

The shot was taken with a D750 and a 85mm 1.8g ;) You will love them when they arrive.



Only reason I can think for all the packaging is for retail display, does seem excessive for a small memory card.
 
Think we all know that the d750 is still the king
