Photography with A7Siii or A7C?


Recommended Posts

I have some upcoming food photography shots to do and I'm wondering which camera to use? The photos are for an online menu only, no print, so I'm not sure if there will even be much of a difference. I know the A7C has the 24 megapixels but is there a reason to go with the A7Siii over the A7C? 

Thanks for any input.

You can use both without any problems.

I had my first photo exhibition a couple years ago and realized I can actually print double the size people recommend without any quality loss, because at the end, it's all a matter of viewing distance.

I have a workmate that uses the Canon R6 to shoot fashion to be printed on billboards. He also crops. Billboards need around 4-6MP for a good rendition of image, because of viewing distance. nobody will sit 10 cm from that billboard to pixel peep.

and reality is, nobody will ever sit 10cm away from your artwork and pixel peep like we photographers do in front of our screens. Even if they do, they will look at your art, not at sharpness.

That's why I could print a 24MP camera to double it's recommended size without any quality loss, because the viewing distance was about 60-90 cm.

How Big can you actually print 4K?

Ok so the a7S III has a 12mp sensor, which is the higher end of 4k resolution. The lower end of 4K can also be 7.5-8 MP, so that is really good. Now imagine going to the cinema watching a 4k image being projected on that HUUGEE screen. Or imagine your Home TV.

There are multiple videos on youtube comparing Prints of a 100MP camera vs the a7S III on a blind test, and most people didn't know which is which.

So you will be fine with both of them, social media requires only HD quality, max 2k resolution, which is plenty room to crop and edit, don't forget it's compressed as well, they cannot zoom in.

 

But I recommend you go to a professional printshop and ask them to print a couple of your images at different sizes so you can see for yourself how large you can print and actually how much information is in a 12MP image. It's a lot more than you'd think.

Try printing an image without many textures and one with textures like trees, branches and so on.

You will be surprised by the results.

 The Sony A7S III is renowned for its exceptional low-light capabilities. If you expect to work in challenging lighting conditions or prefer capturing images in dimly lit environments, the A7S III's superior low-light performance can be beneficial. It allows for cleaner, noise-free images even at high ISO settings.

I've got a food photography gig coming up, and I'm a bit torn on which camera to use. I've been considering the Sony A7C and the Sony A7S III, but I'm not sure if there's a significant advantage to choose one over the other for this particular project. The photos will be used exclusively for an online menu, so I'm not sure if the higher resolution of the A7C's 24 megapixels would make a noticeable difference compared to the A7S III. However, I've heard great things about the low-light capabilities and video performance of the A7S III.

The low-light capabilities of the A7S are so good because it has so few megapixels. The signal-to-noise ratio of these pixels is outstanding, resulting in very low noise at high ISO-settings. For real-world use however, this benefit is questionable: if you downsample a 24 MP image from the A7C to 12 MP, the (random) noise is averaged over several pixels and the final picture will have a very similar noise level as one from the A7S. What's more, the downsampled A7C image will look slightly more detailed because it is downsampled from a picture with more detail information.

    • I mostly see posterization artifacts, which are the result of lossy compressed RAW files (or bad jpeg conversion). Unfortunately, the A6400 doesn't offer uncompressed or lossless compressed RAW. The noise might indeed result from the smaller sensor than what you're used to. If you're not shooting at max aperture, you could try shooting at wider aperture and lower ISO. When you're not shooting at max aperture, fullframe versus APS-C shouldn't matter much in terms of ISO-performance combined with depth of field: at the same ISO and aperture value, fullframe offers better noise performance but with a narrower depth of field. This can be offset by choosing a larger aperture and lower ISO on the APS-C camera. If you want a fullframe camera the size of an A6400, try the A7C(ii).
    • ..unfortunately, the lighting was correct. The shot required deeper shadows. The K1 ff didnt have these banding issues [yes, I know the sensor is larger]. The film shots had details in the same light. The sony files, both the jpg and raw, had this banding/noise - with NO retouch or post adjustments [straight out of the camera]. the camera was purchased new a few years ago and I am trying to determine if there is something wrong, or the settings are wrong, or the camera just cant handle this kind of lighting [studio + softbox]. No shadow detail is one thing... banding/noise in the shadows is unacceptable. Does sony have a body this size that is FF ? Im wondering if that would make a difference..  dw
    • The root causes for banding are uneven lighting, incorrect exposure settings, or compression artefacts or certain kinds of artificial lighting, especially LED lights. Also the lens used plays a role, I have noticed it more with my sharpest lenses, looks like they outresolve the sensor when I have a uniform blue sky. There is more than one solution, and ultimately post-processing, but the root cause has to be identified first.
