24MP APS-C (SLT-A65) VS 24MP FULL FRAME (SLT-A99)

Ive done a comparison. I hope it may be useful for someone making a decision to buy APS-C or FULL FRAME Cam or upgrading from APS-C to FULL FRAME.

Im sorry the page is in German only, you may use guugle translator (if really necessary), or just scroll down to the direct picture comparisons.

You can view the information from here:

You can download all RAW and JPG Files from here for your own testing:

Thanks for the link.  It is obvious you spent a lot of effort and you came up with some good ways to compare cameras.  The results speak for themselves.

I stopped reading...

I stopped reading when I saw this:

* Behauptung (von vielen Usern im Internet):
Bei einem Bild mit einer Kamera mit APS-C Sensor mit 24 Megapixeln gibt es bei ISO 100 kein Bildrauschen.

I have never seen this claim. So I see no need disproving it.

The usual claim is that the 24 MP APS-C sensor will not show more noise than the 16 MP APS-C sensor (at the same exposure and the same final magnification of the full image).

What claim? I don't read German.

What amazes me is how little difference there was between the two, even at higher ISO. Since you have to pixel peep at 100% and higher to see even a small difference maybe getting a FF camera is a waste of money after all. It certainly is for me. I'll stick with APS-C.

My translation:

Claim (from many users on the Internet):
In a photo from a camera with a 24 MP APS-C sensor at ISO 100, there is no noise.

Thank you. I have never seen such a claim either. The fact is every sensor of any size has some noise that will be visible if you look hard enough.

Great job!

Can't say I'm very surprised at the A99's superiority in RAW given the pixel quality of the FF sensor.

Granted, the advantages are not always apparent for most shooters, but it certainly becomes an issue as these characteristics get amplified in post processing.

This is where I'd normally write an impressive summary of my skills and proficiencies.

Thank you all for your feedback.

Yes the noise becomes an EXTREMELY BIG issue as soon as you start some post processing due to the fact that the noise gets amplified. So this is what kept me away from processing those noisy images, i got myself a A99 to get rid of the extreme noise of SLT-A65@ISO100.

Some readers of the comparison did not understand that all the SLT-A65 images in the comparison were taken on EV+1,3 by myself to REDUCE the extreme noise at ISO100. So therefore i have updated the article with new comparison images and explanation to show you how much noise SLT-A65@ISO100 images actually have if you take your pictures with EV 0.0 (and thats the most common way).

The text in the article describes the whole way i went through any why i started taking pictures with EV+1,3 and why i moved from SLT-A65 to SLT-A99 to get rid of the noise (without additional noise removal software-algorithms which also removes details).

As always, i excuse, its all in German. But you may use a guugl translator for your suitable language to get an idea of it.

Enjoy.

Yep. I see it the same way. Sony A65 is quite noisy in todays measure, so better sensors will have less noise, and of course nothing keeps you from doing proper ETTR and postprocess with good denoise. There will always be some noise, but the point is that if one downsizes his image and does not pixelpeep at 200%, it´s fine.

From what I´ve seen, Sony A99 is pretty bad (for its price, and for price of lenses on it). I downloaded old scene images from DPR, and compared to Canon SL1 with my own processing, and to my surprise, that little cam is every bit as good in image quality as A99, if not better - at base ISO speed. Noise, detail and sharpness, all at once. When we go high, APS-C will loose of course, but for noise freaks, there is no other way than shoot ISO100 or even ISO50.

In fact, I´d be also happy if new APS-C cameras could shoot ISO 50 or ISO25. With full color sensor, it would propably make ultimate quality images in pocketable format (EOS M3 ), and there would be no quality increment visible by bare eye, compared to FF. Only difference could be resolution, more DoF choices, more controls. Ideal world!
