D750 w Sigma 35mm Art AF Fine Melody
I conducted fine melody on my 85mm i.8 lens and and then immediatly put on my Sigma 35 without thinking. Non exactly sure how AF fine melody works but would the settings from the 85mm been practical to the 35mm without turning AF fine melody off start? I enquire considering the 35mm is no longer sharp. My other question is this. Is the Sigma dock required to do AF fine tune on Sigma art lenses or tin can I do this with the AF fine tune feature in camera? Thanks!!
Re: D750 w Sigma 35mm Art AF Fine Tune
The D750 has split up fine-tune memories for each lens you lot adhere. It seems to exist based on focal length and discontinuity.
Re: D750 west Sigma 35mm Art AF Fine Melody
They shouldn't be practical to different lenses. Not sure what happens if you modify it, don't relieve, and then change the lens if that's what you mean. But when attaching a lens, and saving the setting, it should be saved to that item lens.
What does the setting say? It's piece of cake plenty to go into the menu and see if it's on 0 or something else I think?

Check the fine tune setting on photographic camera when Sigma lens mounted, i guess you lot accidently saved 85mm profile to sigma likewise. On Sigma value should be 0
As for dock, it only affects the lens you have attached to it, adjusting focus in the lens itself, likewise you can update lens software with it. (Yous tin't practise this with Nikon lenses)
Fine melody on camera values are saved equally profiles, when y'all attach lens, camera will use profile saved for it.

Check the AF Fine Adjust Default value ....

The AF fine tune carte offers two choices - Saved Value and Default. If you make an adjustment in Default, that aligning will be practical to any/all lenses that you oasis't specifically gear up an aligning for. Then only bank check that yous oasis't entered a value in the Default field which could exist affecting your 35mm. I believe one time y'all "register" a lens and give it a "Saved Value", the Default value is no longer practical to that lens. But unless you really want your photographic camera to have some sort of global upshot on all of your (unregistered) lenses, the Default value should be null. Seems like a confusing manner to achieve the goal. I much prefer the Pentax menu for AF Fine Adjustment which simply says "Apply One" or "Apply All".
I believe the dock is only needed with Fine art lenses for adjusting various focus distances - simply I haven't used one. You can use the in-photographic camera AF Fine Adjustment with Sigma lenses though.

Re: D750 westward Sigma 35mm Art AF Fine Tune
I had an effect with my d750 and sigma 35 when trying to fine melody. I call up it seems like your effect would be more similar to this versus an issue with two Sigma lenses. Sometimes it would create a 2nd instance of the lens. So I would fix the value. And then once I reattached the lens, information technology would think that it was a new 35 mm lens (you would see 2 entries in the "list saved values" bill of fare) and so reset the fine tune value to 0. And thus focusing would exist off over again.
I did two things to set up information technology. Offset I went into list saved values carte du jour and changed the lens id for the 35 mm lens from "--" to 0. This seemed to set it properly and should have been a good enough fix. But I had a credit so I ended upward buying the dock and my required fine tune setting was a +20 (quite a fleck already). I fixed all the fine melody settings in the dock itself and then my fine tune value on the camera is 0 and even if it resets, so it shouldn't exist an issue.

Interesting Kevin. I'1000 thinking of getting the sigma dock myself. Could you lot give a brief description of what you lot do to fine tune a lens? Do you have control over tuning at different camera to subject distances?

For this detail lens, there are 4 different distances listed (fixed past the sigma software). I take a lens marshal so I employ that as my target at all the four distances. Information technology tells me if I'm front or back focused. I picked one distance to utilise every bit a test. For me, it needed a +twenty on the camera. I read somewhere here that on sigma dock information technology was nigh one-half. So then I set all 4 distances in the dock software at +10. Then I reconfirmed on the target. I tested the four distances and two needed virtually a i unit of measurement modify. It was actually close and this is at f1.4 and really close distances. And so fastened to the dock again and validated it all looked good.
If y'all are really particular, I guess that there could be quite a bit of attaching the lens to the camera and back to the dock. Just for me it was just a few times. And I was never happy with my lens before as the focus was never consistent. But I have since changed cameras and on the new camera it was at the far end of the fine tune scale. Now with the dock, it is great. And I like the lens a lot more.
Hope this helps.

For this particular lens, there are iv different distances listed (fixed past the sigma software). I accept a lens marshal and then I use that as my target at all the 4 distances. It tells me if I'm front or back focused. I picked one distance to utilize as a exam. For me, it needed a +twenty on the camera. I read somewhere here that on sigma dock it was well-nigh half. So then I ready all iv distances in the dock software at +10. And so I reconfirmed on the target. I tested the 4 distances and ii needed well-nigh a 1 unit change. It was really close and this is at f1.iv and really close distances. Then attached to the dock once again and validated information technology all looked good.
If you are really particular, I gauge that there could exist quite a bit of attaching the lens to the photographic camera and back to the dock. But for me it was just a few times. And I was never happy with my lens earlier as the focus was never consequent. Simply I have since changed cameras and on the new camera it was at the far finish of the fine tune scale. Now with the dock, it is great. And I like the lens a lot more.
Hope this helps.
Indeed information technology does - thank yous. I take the 24-105 Art and I'm very happy with it, but tin't help wondering if the dock would squeeze that little flake more than out of information technology. I'm besides considering the 50 and peradventure 35 primes. I love the thought of having that much command of my lenses focusing accuracy.
