hi everyone hi everyone it's matt again from mark roberts motion it's matt again from mark roberts motion it's matt again from mark roberts motion control with another tutorial control with another tutorial control with another tutorial this time showing you the focus this time showing you the focus this time showing you the focus calibration procedure calibration procedure calibration procedure to correctly use the target tracking to correctly use the target tracking to correctly use the target tracking capability of flare capability of flare capability of flare and enable the focus to follow the and enable the focus to follow the and enable the focus to follow the target accurately target accurately target accurately the lens focus axis must first be the lens focus axis must first be the lens focus axis must first be calibrated calibrated calibrated the focus axis shown here is currently the focus axis shown here is currently the focus axis shown here is currently set to set to set to independent mode and so the displayed independent mode and so the displayed independent mode and so the displayed position of the axis position of the axis position of the axis is determined essentially from its is determined essentially from its is determined essentially from its internal scale factor internal scale factor internal scale factor the purpose of the focus calibration is the purpose of the focus calibration is the purpose of the focus calibration is to calculate the correct scaling factor to calculate the correct scaling factor to calculate the correct scaling factor for the attached lens for the attached lens for the attached lens to set up a new lens open the lens setup to set up a new lens open the lens setup to set up a new lens open the lens setup menu and select menu and select menu and select new the focus calibration panel new the focus calibration panel new the focus calibration panel will automatically be opened showing a will automatically be opened showing a will automatically be opened showing a simple procedure to calibrate the focus simple procedure to calibrate the focus simple procedure to calibrate the focus firstly give your lens a name and enter firstly give your lens a name and enter firstly give your lens a name and enter the focal length the focal length the focal length this is a lens that moves to focus this is a lens that moves to focus this is a lens that moves to focus rather than the camera body rather than the camera body rather than the camera body so the moves checkbox will remain as is so the moves checkbox will remain as is so the moves checkbox will remain as is to begin the calibration ensure that the to begin the calibration ensure that the to begin the calibration ensure that the focus axis is disabled focus axis is disabled focus axis is disabled by pressing the disable focus button by pressing the disable focus button by pressing the disable focus button this will allow you to manually move the this will allow you to manually move the this will allow you to manually move the focus focus focus while the focus motor is still in mesh while the focus motor is still in mesh while the focus motor is still in mesh with the lens with the lens with the lens rotate the focus to the infinity mark rotate the focus to the infinity mark rotate the focus to the infinity mark and then and then and then zero the focus axis this signifies the zero the focus axis this signifies the zero the focus axis this signifies the end of travel end of travel end of travel and corresponds to the home position of and corresponds to the home position of and corresponds to the home position of the axis the axis the axis now rotate the focus to the close focus now rotate the focus to the close focus now rotate the focus to the close focus mark on the lens mark on the lens mark on the lens on this lens it is at two feet enter the on this lens it is at two feet enter the on this lens it is at two feet enter the focus distance focus distance focus distance and stall the axis position by clicking and stall the axis position by clicking and stall the axis position by clicking store focus store focus store focus now move the focus to about halfway now move the focus to about halfway now move the focus to about halfway along the travel along the travel along the travel and store the position and the distance and store the position and the distance and store the position and the distance on this lens it is at four on this lens it is at four on this lens it is at four feet at this point the focus curve can feet at this point the focus curve can feet at this point the focus curve can be calculated based on the known be calculated based on the known be calculated based on the known three points an alternative method of three points an alternative method of three points an alternative method of calibrating the focus calibrating the focus calibrating the focus is by using a lookup table mapping is by using a lookup table mapping is by using a lookup table mapping several axis positions several axis positions several axis positions to corresponding focus distances but to corresponding focus distances but to corresponding focus distances but this isn't required for most lenses this isn't required for most lenses this isn't required for most lenses if you want to use this method add if you want to use this method add if you want to use this method add additional rows and store the axis additional rows and store the axis additional rows and store the axis positions positions positions along the travel of the lens press the along the travel of the lens press the along the travel of the lens press the calibrate focus button when you're done calibrate focus button when you're done calibrate focus button when you're done this will calculate the scaling factor this will calculate the scaling factor this will calculate the scaling factor for this lens for this lens for this lens many of the system focus axis settings many of the system focus axis settings many of the system focus axis settings have been copied to the focus access have been copied to the focus access have been copied to the focus access settings for this lens settings for this lens settings for this lens if you would like to modify any if you would like to modify any if you would like to modify any additional settings click additional settings click additional settings click lens focus axis the minimum and maximum lens focus axis the minimum and maximum lens focus axis the minimum and maximum positions of the axis have already been positions of the axis have already been positions of the axis have already been filled in for you filled in for you filled in for you based on the close and infinity based on the close and infinity based on the close and infinity positions of the lens positions of the lens positions of the lens once you are finished save your changes once you are finished save your changes once you are finished save your changes and apply these settings to the system and apply these settings to the system and apply these settings to the system focus axis focus axis focus axis the final step is to store the the final step is to store the the final step is to store the calculated calibration within the lens calculated calibration within the lens calculated calibration within the lens each lens contains its own focus access each lens contains its own focus access each lens contains its own focus access settings that have been calibrated settings that have been calibrated settings that have been calibrated this allows each lens configuration to this allows each lens configuration to this allows each lens configuration to be quickly loaded be quickly loaded be quickly loaded and be ready for use to use this lens and be ready for use to use this lens and be ready for use to use this lens now now now press the apply button lastly save this press the apply button lastly save this press the apply button lastly save this lens to disk by pressing the save button lens to disk by pressing the save button lens to disk by pressing the save button so that it can be retrieved at a later so that it can be retrieved at a later so that it can be retrieved at a later time and there we go time and there we go time and there we go you can now create a move and have the you can now create a move and have the you can now create a move and have the focus automatically pull to the target
