Hello,

 

Yesterday my A7s- Camera went black, no buttons worked. I tried all the buttons and nothing would response. I then took out the battery and then put it back in and it worked fine. This just happened to me after changing lenses too. Not sure if this is what caused it. 

 

This has happened 2 times now. 

 

I know I am due for a firmware upgrade, I will try that next to see if the problem happens again.

 

Has anyone else had this problem? I hope my camera is not breaking down.

 

 

Thanks!

    • I elected to upgrade from Sony A1 to the A1 ii and am seeing some significant focusing challenges in the little time I've spent with it so far. Less than 10% of photos appear to be in focus when photographing small birds in subject mode birds with seemingly no improvement when subject mode is changed to birds/animals/people. Scenario: Sony A1 ii, 200-600 G lens @ 600mm, F6.3, shutter speed on male cardinal (in-focus mostly) at 1/250 ISO 125 and female cardinal (nothing in focus) at 1/1600 ISO 100; AF-C set with eye supposedly in focus in both shots. Lens has AF on, OSS on, Mode 1. I've tried switching out lenses using 100-400 with and without 1.4X converter and used handheld and used tripod. Photos are at a distance of 20-25 yards. The photos below are within a couple yards of one another. There is seemingly no improvement in AF performance despite the combinations of lens, tripod and focus zones attempted. Birds are stationary. Many of the photos will have everything in the frame seemingly out of focus and some may have the head in focus and rest of body out of focus and immediate area around bird slightly out of focus at F9-F11. I considered that I was cropping too much and had pixel peeping / expectations problem, but some photos are wildly out of focus when supposedly focusing on eye or body. Neither photo below is cropped. Ideas are welcome!

    • Agreed, but it's ancient thinking. Any modern forum lets you edit whenever. It's simply a setting they could click to turn off. It's one reason I won't post many photos here. After 10 minutes I lose complete control over my own property. 
    • Bokeh is indeed as much about the quality of out of focus blur as it is about the quantity. Especially the focus transition zone (where things go from 'within focus' to 'out of focus') may be under scrutiny when assessing bokeh. Another optical 'defect' which manifests itself in bokeh is LoCa (longitinal chromatic abberation). Some call it ugly green/magenta halos in contrasty out-of-focus areas, others call it character.
