Hi, Im a bit confused about other threads I have read regarding the X5 camera calibration process so any information or corrections would be appreciated. Most videos I have seen sugest calibration on a high contrast subject thats 50mtrs away (some are sugesting a lot further), I dont understan the logic behind this as it doesnt represent the hyperfocal distance of the DJI 15mm stock lens at all, to clarify my knowledge a little further;
Using the DJI 15mm stock lens as an example with a subject 10 metres away my calculations as a photographer would be as follows
Subject Distance 10m
Aperature F1.7. Aperatue F5.6 (optimum quality for this lens for both centre and edge sharpness)
The hyperfocal distance of this lens is 8.93m The hyperfocal distance is 2.67m
Depth of Field in Front of subject 5.28m Depth of field infront. 7.90m
Depth of Field Bedind subject oo Infinity Depth of Field Behind. 00 Infinity
Bearing in mind the above facts regarding subject distance, depth of field both and the hyperfocal distance (sharpness in front and behind subject) can someone tell me why the calibration requires the subject to be 50mts or further away as this is technically squandering the benefits of the hyperfocal distance of the lens.
Im probably missing the point here but I do read that a lot of X5 users are experiencing problems with their lenses even after calibration. I realise that most of you will probably be on the Inspire 2 now but for those still on this craft and for me as a Newbee some more information would be nice (also have the inspire with X3 where calibration is not relevant).
Also I plan on buying the Oly 25 and 45mm lenses do either of these require a balancing ring if used with an ND or haze filter (I assume not). Some clarity here would be nice as I dont want to damage my new craft.
