In Topic: D5500 acting weird - deliberately going out of focus

09 April 2019 - 03:25 PM

Unless someone has another solution, I'm thinking that it's time for a trip to the waterfront (a grave for the camera) and then a trip to the Sony store; can't see buying another one of these.


Well this is indeed not a problem with mirrorless as the focus is determined at the sensor. And while Sony probably has the best on sensor phase detect system out there right now, the new full frame mirrorless glass is stupid expensive (not just Sony, but Nikon, Canon, and Panasonic too).

I chose to go Panasonic M43 as the glass is great and reasonably priced. Plus Panasonic has the fastest, most accurate contrast detect AF on the market. Probably the best there is for static scenes, but not so much for tracking moving subjects.

It really is about the kind of photography you do as to which models will address it better.

Are you using VR equipped lenses? They can sometimes hold on to a scene and then jump off it while panning, especially if they don't have a specific panning mode.

The 4k bit rate of the D7500 is 144Mb/sec… so a card capable of writing 18MB/sec (which the ultra plus should be able to do in the D7500) should be fast enough, although with little margin for error.
 
But there may be something else causing this than dropped frames on the card. Does it play back smoothly on the camera's screen? It is entirely possibly your computer is struggling to play 4k video.

Sounds as if the phase detect focus system has gone off into the weeds. Live View uses contrast detection via the image sensor so it is not affected by that malfunction.

 

It probably needs to go to Nikon.

until we know more

 
LOL. Of course Nikon says send it for service in the manual. I think every user manual I've ever read says the same thing, yet most of us lock up the mirror and swab our sensors.
 
I find it almost shocking that IBIS has been around for years and we are no closer to knowing what the preferred method is. I have heard everything from "turn the camera off and remove the battery" to "power up the camera so that the IBIS system steadies the sensor"… and these are all simply assumptions made by a B/Vlogger.

But whatever it is… it's clear the OEMs ain't sayin'. (c;
