Hi (oder Servus) Rennmaus,

I don't have an EOS Camera yet, but plan to get one for widefield captures, so your plugin comes in handy :-)

As an enthusiastic owner of an Astromechanics adapter, I would like to provide some input here.

In the meantime I always take two shots per focus point, the HFR curve becomes more stable, costs some time but pays off.

That you come up with 9 intervals, I'm sure you do for a good reason. With more intervals you could adjust even more finely, and on the other hand see by logging when it is no longer worthwhile. For example, I can't get my Canon 50mm with my Astromechanics from infinity to the best focus point (HFR worst equals four times the value of HFR best) within only 9 shots.

This could be something that I am doing wrong rather than an issue.
I have an EOS 600D camera and an EF 400mm 1:2.8 L IS II USM lens. I am using LensAF 2.0.0.0 and NINA 2.1.1.3005.
The Calibrate Lens button works as expected, it slews the lens focus to max infinity, although I notice that does not seem to slew all the way to max infinity. It then leaves the focus there and sets the Position and Target Position to 100. Unfortunately, for this lens, the best focus position is now approximately -100, which cannot be reached because the focus position apparently cannot be set below zero. Perhaps the user could specify the position value after slewing to max infinity and then the Calibrate Lens button could slew to max infinity, set the position, and then move the lens to position 100.
I should note that the whole routine works very nicely if I just set the lens near optimum focus by hand and don't run the calibration routine. This, however, leaves me with an unknown shift in focus position from one night to the next. I would like to develop a focus position as a function of temperature curve and this unknown shift makes it harder, though I can see ways to get around the problem.
If this is a peculiarity of my lens I would be happy to work with you doing some testing. I could think about fixing the problem myself, but C# is not my best language.
I await comments or questions.

I get a camera not ready error after auto focus. Auto focus happens fine but when the sequence is suppose to start the error happens. I did not think to get the error screen shot. If you need it let me know.

Beeep

I'm attempting to use the Lens AF plugin with Canon EOS 60Da camera and a Canon 50mm EF lens. N.I.N.A. connects to the camera successfully and Manual Focus on the Imaging tab all works as described in the plugin documentation. The "Start autofocus" button on the Imaging tab is grayed out however. Am I missing something obvious here?

Hello,

The focus point definitely moves 8 times, but as you can see on the screenshot below, the best HFR is around 2.4. Yet, the focus point chosen is not this one. I end up with a HFR of 7.6, which is completely out of focus.
