On a recent astrophotography shoot I took foreground images at ISO 1000, 2 minutes, F1.8. It resulted in extremely noises images with hot pixels that are unrecoverable. I have never needed to use Long Exposure Noise Reduction in any of my other cameras and have never had noise like this even at 4 minutes in any including my Sony A7iv and very old Nikon D750. The file was medium RAW 26MP with the hopes that by reducing the MP it would decrease noise levels. Outside temps were between 55-60F and not hot enough to cause hot pixels. Is this an issue with my sensor or is the A7Rv just this bad at high ISO long exposures? I did an indoor test dark frame with same setting but at 800 ISO with lense cap on and got the same results. I tried uploading file of 800KB but will not upload for some reason.
Hi there,
Newbie question here and also a first timer sony camera user. I just bought this past few days a ZV-E1 for video recording. And I just realized the photography side that I also need for some task. I end up looking for Alpha 7R V and watch the review from Youtube but still I need some advice from PRO's here. I'm also considering a Alpha 7CR. Anyway I'm open for any advice for a sony alpha best for video (Vlog recording) and also good for photography. Thanks so much in advance for your time.
