I have been getting back into the Sony A7 IV recently. The more I think about it, the more I think this (along with 2018's a7r III) is where Sony finally got things right and properly came of age. It's really very good and current used prices make it one of the best bang for buck full frame cameras. Constantly surprised at how good the EVF is for the price. The IBIS is much improved from previous gen. As is the colour science. The menus are still complex, but they're much snappier and faster. And the grip, all buttons, really have much more feel. The fact they kept the build quality and ergonomics the same as some of their most expensive cameras, i.e. a9 II or original a1, is the opposite of what Panasonic did with the S1R II being in a mid-range S5 body. And although the sensor is slow compared to an a1 or stacked sensor camera, the price is low, the image is fantastic, the 4K is oversampled from 7K and you still have the option of faster frame rates in the Super 35mm crop modes. Also although the H.265 bitrates are quite low by 2025 standards, the codec holds up magnificently. And small files are what I like. Autofocus is not up to the high-bar of a 2025 flagship Sony like the a1 II of course. But it's pretty damned good. £1600 is a steal (used). Bring on the a7 V... Rumours have us expecting the same 33 mp sensor but partially stacked, but I don't they put a 7K or 8K mode in there. 4K/60p without a crop, maybe 120p in the S35 mode more likely. -
Since the sensor is dual gain, below a certain ambient light level you should switch to the higher gain setting, ISO 6400. When you do that, presto, the noise is either gone or greatly diminished. -
SSD review says 256GB and 512GB Lexar Professional Golds get up to 85C and the 2TB card only to 63C. In the same review Delkin Black 512GB is the coolest at 39C. I have had no problems with 2TB Lexar Professional Gold in Z6iii at 25C in direct mid day sun, but 6k50p NRaw may not be as taxing to the camera and card as Panny’s 422 H.265. -
it started happening faster in hotter conditions, 24-27C, but still happens at around 20C. When I narrowed it down to the card being the issue, I would just leave the camera running on my table while doing post work, and would regularly fill up the card or run out of battery with the Delkin or OWC without any warning, but with the Lexar card about 10-12 minutes in, the heat warning sign would come on, and it would terminate recording in about 20 min or so. PS Should add the cards that cuz thermal issues for me are 128GB gold Lexar Cards -
