This issue has caused me such a headache. I agree it is really mind boggling that Sony doesn't allow you to turn this setting off. I haven't had a chance to test yet but I believe this may be the solution: https://www.youtube.com/watch?v=Bh_gfEsFGtA -
hi, i have same condition as this. the AF are stuck and also the rest button not working when the AF stuck. so i replug the battery and change the autofocus into DMF for temporary setup till i can pay the sparepart for this. the autofocus still fine but it goes by press dial button for focusing *the sony guy tell me that i have to change the shutter due some error hardware which i think that not the problem as i still can take photo from ithe camera itself -

Oh. Okay Thanks for that information Pieter - every day's a school day :-) -
I recently sold my G9 camera that I used for wildlife and moved to the Sony System for several reasons like larger sensor and dynamic range and... But, two areas where Sony seem to be behind the Panasonic G9 are in, in camera multiple image high res and high dynamic range imaging, and in tracking and focusing on bird's eye. In fact, the animal tracking for BIF, IMHO, seem markedly less competent than my former G9 system. I would hope Sony corrects these deficits by a release of a firmware update for the existing A7R4 camera. Of course someone may say why don't you get the new A1 Sony with all these great features. Simply, why should one be pushed to spend $6K plus for a camera when the $3.5k camera should have better internal focus and composite making capability than my former $1.5K, three 3 year old design, G9 had? The A7R4 is a wonderful camera, but it still has some serious downside that much less expensive cameras, and older generation cameras, have done away with. PCR -
In part you are correct @thebeardedgroundsman, except that the camera subtracts the dark image from the original exposure rather than adds them together. Unlike normal noise reduction (which is only applied to JPEG-output) this procedure is baked into the RAW-file, resulting in a single file. No additional post-processing is needed. Long-exposure noise reduction is not meant to correct for 'regular' noise (often related to ISO-setting) but corrects for 'amp noise', which is a result of the sensor becoming hot during a long exposure. This heating is not uniform, and results in halos in the hotter areas of the frame. By subtracting a dark frame with the same exposure time, the final image is corrected for these hot areas. This is impossible to do in post with regular noise reduction and requires local corrections and knowledge of where your sensor tends to get hotter.
