Απάντηση: Re: Nikon D850
Έριξα μια γρήγορη ματιά στο review του Dpreview για την Nikon 850 και μου κινησε την περιέργεια το παρακάτω που αφορά την απόδοση του συστήματος εστίασης, θα ήθελα ένα σχόλιο από όσους χρησιμοποιούν πιο παλιά μοντέλα με χαμηλότερη ανάλυση αισθητήρα.
"The D850 would sometimes, mid-burst, lose track of the subject it had initially been tracking. This happened both in the middle of the autofocus area, as above, and also near the edges (usually at the apex of a turn, indicating a change in approach speed to the camera). It happened regardless of whether the camera's 'Subject Motion' parameter of 'Focus tracking with lock-on' was set to Erratic, Steady, or in-between."
"However, the D850's massive resolution shows up some inherent issues in terms of how DSLR autofocus systems work that might prevent you from getting all 'keepers' all the time, especially if your lens requires calibration. This shows up most often in wide-aperture work, such as some styles of portraiture, where autofocus precision is of paramount importance"
