A typical limitation with newer (and usually extra reasonably priced) cameras is that increased body charges require a crop mode. Generally that is minor, like how the a7S III crops in 10% for getting 4K at 120 fps, and different occasions it’s a big change, just like the a7 IV featured right here which requires Tremendous 35mm for 4K at 60 fps. There simply is likely to be an answer for the a7 IV’s crop.
Gerald Undone might have found a workaround or hack that means that you can report 4K at 60 fps with the a7 IV with none crop. It’s very attention-grabbing and is likely to be helpful for you.
To do that out you have to an exterior recorder such because the Atomos Ninja V. It’s bizarre conduct regarding the a7 IV’s HDMI output. Within the digital camera’s settings if you happen to set the output decision to 1080p you’ll be able to simply set the body price to 60p.
Then, if you happen to head again to the decision you’ll be able to set it to UHD 4K 2160p. The Ninja V will really seem to learn this as 4K at 60p with none crop.

Is that this all true? One query, even when the information seem like 4K 60p, is whether or not the digital camera is doing an upsampling from the unique 1080p setting.
Gerald enlisted iPhonedo to do some assessments with the digital camera. It’s true that you’ll find yourself recording 4K 60p footage with this mixture of settings. Nevertheless, in comparison with the interior 4K recording you may get the exterior footage simply doesn’t have the identical diploma of element. It undoubtedly seems just like the “hacked” 4K footage is upsampled 1080p footage.
Nevertheless, the upscaled 4K footage does look higher than native 1080p footage. It’s nonetheless most likely finest to do the sort of transfer in put up anyway and it’ll prevent the difficulty and file sizes.
Anyway, it doesn’t appear to be you really get true 4K at 60 fps with no crop. You’ll get high-quality 4K 60p footage within the crop mode although, so don’t rule out the a7 IV until you simply can’t get by with any crop mode. In that case you must go along with the quite a few different digital camera choices, just like the a7S III, which might do 4K 60p and above with no crop.
