Compressed RAW vs Uncompressed RAW on Sony A7IV

In this video I'm breaking down the differences I found between different RAW format compressions that are found in the newest Sony A7IV camera. We have 3 options to choose from - Uncompressed, Lossless Comp and Compressed and they also come with the limitation in the camera high speed shooting. But is the quality difference visible in final photos?

Wow! This might be the most useful YouTube video I’ve seen so far on the a7IV. Thank you. I’ve been a RAW shooter forever always using uncompressed format but this might change my mind

[Revan]

This is soooo useful Maciej. Im totally sold on the A7iv. Im going to switch from my trusty D750s to Sony. Your content aimed for wedding photographers was key for my decision. Thank you

[trippalhealicks]

Thank you for this analysis. I've recently been bouncing between lossless compressed and compressed with my A1. Glad to hear I can stick with compressed and not miss out on much, but gain the true 30fps bursts.

Another great video Magic! I just got my A74 and I’m excited! Got a wedding in a little over a week and gonna put it through its paces.

Since the a74 has 3 custom mode slots, you could assign uncompressed to one slot and compressed to another slot.

I have mine on order and so anxious to work with it. Thanks for this!

Deadly video! Great info, thanks very much and I love the t-shirt 😜

Brilliant video style as well. No useless shenanigans. Just straightforward information.

[Kinadnuf]

Literally bought an a7iv yesterday, 28 July, and this video is SO helpful and confirmed what I thought, cheers buddy. Subbed too 🇬🇧

[ccarlos]

Thank you for explaining this so well..you win a new subscriber....God bless you and your loved ones

[PaperKittenProd]

really useful video! thank you so much!

[Totte.Lundgren]

Very useful when thinking of giving up on Canon to grab the A7IV.

I'm in a beach town in Southern California and frequently shoot into a sunset. To preserve sunsets and the detail in the ocean I heavily underexpose my couples. In these common situations uncompressed raw has an advantage. I set a memory recall on my PSAM dial for uncompressed in those scenarios.

[HybridePassion]

Thank you very much ! I use A7 IV and I do exactly what you say : Raw lossless compressed except when I want 10 fps...and it's not a problem indeed !

[kaiyin]

Can you compare A1 and A74 Skintone, screen colour and ISO? Thank you so much.

[JasonLawrenceNoel]

⁠​​⁠Magic!!! What raw compression do you use most often on your a7rv ?

[juanignaciocali]

Hey man! Great video! I recently get a 7IV but i can´t previe the photos. Not even in Lightroom. Do you have any recomendation? I use a macbook pro. Thanks!

[RickyTOHK]

Very good review and answer my question

[BusStopBourbon]

0:53 Have you ever discussed what camera strap you use? I've wanted to dual cam but I'm not a fan of the holdfast moneymaker. Thanks!

[layed_black]

Thanks a lot! Love your content about the 7 iv!

Thanks Magic, that's a useful insight. Like you I always shot lossless compressed on earlier Sony models, a7riii, a7riv and a9. I'm in process of adjusting my kit going forward to start embracing video as well as stills. Sold all my bodies and just taken delivery of an a7iv. The idea of buying a a7Siii, although great for video, never seemed like a good idea for stills given just 12Mb.

As I also like shooting sport, my a9 was last body to go. Hence your timely 10fps RAW lossy compressed is essentially OK unless I screw up the exposure vs 6fps lossless RAW. If and when I can stump up the funds for an a1, then it's good to know one gives up little to get 30fps - not that I can imagine often having that need for most sports work (I'm doing for fun as an amateur, not professionally where I might need to explain why I missed a shot).

That said I'm genuinely puzzled as to why Sony would 'knobble' the fps down from 10 to 6 fps if there is so little practical difference between file sizes and compression algorithms? If it's the same processor as found in the it a1, then it's unlikely that the Bionz processor is causing any 'bottlenecks effect when calculating the compressed file.
