Don't see Lens focus options BYN

[Mach13]

Hi Firstly lovin this app.. Brand new to astro, my D7000 and everthing.. so its all a steep curve

 

I'm using the BYN trial version 2.12 with my Nikon D7000  The attached lens is Nikon AF Nikkor 28-100mm f3.5-5.6

Everything appears to have connected fine

The camera is in auto focus mode

But when I'm in 'Frame and Focus' I don't get the Lens Focus Adjustment option in the live view pane.

 

The auto focus is still working on the camera... What am I missing?

PS I've looked at the logs and i've noted that Lens references state LensStatus = '0'   Does this indicate the lens Isnt being picked up? Should this model/type be picked up?

 

Be grateful for your guidance

This is not available on most nikons.  Only selected newer mirrorless nikons have this in BYN.

I'm wondering if this feature will be likely be added to future updates?

Reason I ask is it defo works in another 'control...nikon' app I have on demo so I know my camera has the capability.

Not having had any clear skies at all since I've had the DSLR I've no idea how much of a pain it is to try and focus manually versus through the app..it just seems such a cool feature for fine tuning.

Nobody said that the Camera doesn't have the ability - rather that the Nikon SDK (developed and published by NIKON) doesn't expose certain functionality to the Program(s) which connect to the DSLR through that SDK.  This is complicated by the fact that NIKON has used several 3rd-party Companies as sources for the Sensors and Processors in various Model Series.

Certain other "control...nikon" apps use other connectivity methods than the SDK - methods which expose different features (and only work for some Model Series).  BYN Developers decided to stick with the SDK, as that is provided by Nikon (for almost all DSLR and MILC Models) and doesn't need to be coded differently for different Models.

No, not an old Nikon, sorry.

Thanks s3igell for your detailed reply - just for clarity, I wasn't implying anything was said,  I was merely making a functionality point and asking a question, which you then answered eloquently so thank for that.. much appreciated.

Thanks Admin,  It's not a major issue I just wondered.  I still feel BYN has the edge over anything else I've seen to-date... but that focussing tool would have been the icing on the cake.  I'm going to be starting out with using my camera on my scope for lunar and planetary stuff so the focussing will be a mute point for that. But at some point I'd like to move onto other basic deep sky stuff and figured it would be very helpful in the longer term.. But I guess not essential.  When I bought my camera I had no idea it could be linked to my laptop at all - so this is all a big bonus.

I just tried to do the focus feature with my D610 and it does not come up either and I am using the latest version, I am assuming it is something to do with the SDK, has this never been addressed?, would be nice to be able to use this, instead of focusing by hand!   Thanks     Lost

I am a Canon user, but the BYN should operate much the same as BYE does. What I see in BYE is the following:

1. you can only control lens focus from the Frame & Focus screen
2. the autofocus lens must be attached to the camera at the time that you connect the software to the camera.
3. the lens must be in AF mode in order for the software to adjust the lens.

If conditions 1. and 2. are met then you should see the lens control (chevron) buttons at the top of the Frame/Focus Center when F&F is active. Below is a screenshot from BYE. BYN should appear similar.

If you are unable to make these buttons display then it is likely that BYN is unable to control an autofocus lens for the D610. If so then it indicates that the lack of support for focusing a lens for your D610 is due to a problem with the Nikon SDK.

Unfortunately there is nothing that O'Telescope can do to address this. Only Nikon can address needed fixes/enhancements to the SDK. If Nikon treats the SDK like Canon treats theirs, there is no way for developers or users to report bugs, suggestions, or other issues related to that software.

If there is no issue with the SDK then perhaps it is a bug in BYN. In that case, since lens control works with other Nikon models, it is likely due to some difference between the D610 and other cameras. This would require the O'Telescope developers to have a D610 model on-hand to test and debug with. They have said previously said that it would be cost-prohibitive for them to purchase every model that Canon and Nikon release and that to rent a specific for testing can sometimes take months.

That said, the Supported Cameras table says that BYN has been tested with the D610 so this means that either O'Telescope has, or did have, a camera for testing or that users have reported that the software works as expected.

One other possibility is that there is some setting in the camera that is preventing BYN from being able to control the lens focus. Some "advanced" focus modes can affect this capability. Dumbing down the camera by selecting single point autofocus may provide some relief.

I hope that this helpsl.
