On my quest to replace the Sony a1, I took my cameras out to Lost Lake to photograph the Milky Way rising over Mount Hood Link to raw files: drive.google.com/file/d/1aEnk... Follow me on Instagram @spencerlee808
I have a Sony A7R V, I feel the noise level on the A7R V is over looked by most people. Give it a proper exposure in the dark, it performs as good as other cameras. I've shot Orion nebula with it paired with the 70-200 f2.8 GM II and results are very clean. I also compared it with the A7 IV in low light, it's not that big of a differences in noise level if both are collecting enough light(1-2 min long exposure in pitch dark for foreground). That said, if it's underexposed, the A7R V revealing more noises than the lower mp cameras like the A7 IV. This is why if you compare the sky portion of the sample shots you took they look similar in noise level(because there is more signal covering the noise) while if you bring up the shadow portion of the foreground(which is underexposed) you see the 61mp sensor shows more noises because it's noisier on pixel level due the smaller size of each pixel. IMO, if you do tracked MW shots, the 61mp camera is better because it captures more details. But if you do single shots or time lapse, then the lower mp cameras is a better choice. Anyways, just my 2 cents. Nice comparison vid! Clear skies 😊
Thanks for the test. It could be that in electronic shutter the images drop to 12 bit quality vs 14 with mechanical shutter. Odd that the a1 would not have hot pixels. Long Exposure Noise Reduction wasn’t turned on by mistake? Unlikely, as you would have noticed that. Does it have some other image softening routine the others don’t? Thinks again and great shots!
Yeah bro, after careful consideration, I think I’m going to go with the oldie but goodie a7iii. In addition to my a7rV, 24Mp seems the best for me as a backup body/low light camera…
