Sony A58 Image Quality Comparison

The crops below compare the Sony A58 to the Sony A57, Canon T5i, Nikon D3200, Pentax K-50 and Sony NEX-6.

Note that these images are best quality JPEGs straight out of the camera, at default settings including noise reduction. Each camera was shot with one of our very sharp reference prime lenses.

The A57 had great image quality for the price, but the A58 takes it a few steps further. With roughly four more megapixels of data, the mosaic crop from the A58 here looks sharp and the pink fabric swatch has nice detail. A noticeable improvement to Sony's entry-level DSLR image quality.

The Sony A58 is far superior to the T5i across all crops above, especially with the sharpness in the mosaic and the detail in the pink fabric swatch. The same goes for the red fabric swatch.

The D3200 boasts roughly four more megapixels than the A58, but the first two crops have a smeared appearance compared to the Sony. The higher resolution does, however, help in the difficult red fabric swatch, an area that Nikon typically does particularly well with.

Pentax K-50 at ISO 100

The Pentax K-50 has roughly four less megapixels than the A58, and it shows in the fine detail department. The K-50 also does a relatively poor job with the red fabric swatch and renders the pink fabric swatch with a pumped and artificial magenta hue.

Also with four less megapixels than the A58, the mirrorless NEX-6 still does a nice job against its cousin, with sharp detail and a good job with the red fabric swatch. The A58's increased resolution certainly shows its teeth (or, in this case, threads) in the pink fabric swatch.

 

Moving onto ISO 1600 now, where noise processing starts to show its character.

The A58's strength against its predecessor is particularly evident above in the mosaic tiles, which are smeared and soft in the A57 but still fairly tight in the new A58.

The T5i loses most-all contrast detail in both the mosaic and the red fabric swatch, with the A58 a clear winner in image quality between the two.

The D3200 images just don't look to be in the same league as the A58's here, with pronounced noise apparent in the bottle crop, softness in the mosaic, and both noise and softness in the fabric crops. Not really a close call in any of them.

Again, the K-50 struggles with rendering the red fabric swatch, and pumps magenta into the pink swatch, as well as some artificial yellow into the mosaic frame. It also imparts more noise into the bottle crop than does the relatively clean A58.

As with base ISO, the NEX-6 does a nice job, going toe-to-toe with the A58, but the higher resolution DSLR comes out slightly ahead in most areas, especially fine detail.



And, below at ISO 3200, the stakes really start to show in today's cameras.

Yet again the A58 has a better handle on rendering some detail, even at this ISO, than the A57. This should come as no surprise, but if you're thinking of trading up it's still nice to know, as it is not always the case for every successor camera.

The T5i really loses ground here, and just can't match stride with the A58 for image quality at this level. Most-all image crops are either smeared or noisy in comparison.

As with the T5i, the D3200 can't match stride at this ISO with the A58. Images are grainy in areas, soft in others, and not particularly usable in general.

Noise in the shadows and bottle for the K-50 become much more apparent here compared to the A58, and the differences in the fabric crop are more pronounced as well.

Similar showings from these two cousins at ISO 3200. As stated before, the higher resolution pays off for the A58 in some of the more detailed areas like the tiles.

Detail comparison. Sony emerges as the clear victor in this fine detail table, with both the A58 and the NEX-6 doing a better job at resolving detail across the ISO spectrum. The D3200, K-50 and T5i do a nice job at base ISO, but then quickly lose ground as ISO rises. By ISO 3200, the Sony cameras are the only two left standing.

 

Sony A58 Print Quality Analysis

Excellent 30 x 40 inch prints at ISO 100/200; a nice 11 x 14 at ISO 3200; and even prints a good 4 x 6 at its highest ISO of 16,000.

ISO 100/200 prints are very nice at a whopping 30 x 40 inches, with excellent detail and vibrant colors. Great wall display prints are possible at 36 x 48 inches.

ISO 400 makes a very tight 24 x 36 inch print with sharp detail, and wall display prints up to 30 x 40 inches.

ISO 800 yields a nice, crisp 16 x 20. The 20 x 30 inch print here is suitable for less critical applications where minor film grain-like noise is OK in some areas.

ISO 1600 is capable of a good 13 x 19 inch print. There is minor noise now apparent in some shadow areas, and a slight decrease in contrast in our target red swatch.

ISO 3200 prints a good 11 x 14. There is now a fair amount of noise visible in some flat areas, but otherwise a nice print overall.

ISO 6400 produces a nice 8 x 10 for this ISO. It is beginning to lose contrast detail in our tricky red swatch, as most cameras do here, but a very solid print.

ISO 12,800 prints a good 5 x 7, with colors still popping nicely. This is the same print size we rated as good at this ISO for the A58's acclaimed great uncle the RX1.

ISO 16,000 makes a good 4 x 6. This is significant because so many cameras we have reviewed lately do not yield a suitable 4 x 6 at their highest ISO.

We could say the Sony A58 does a very good job in the print quality department from JPEGs, but when you consider its body-only street price of somewhere under $600, it'd be fairer to say it does an excellent job. We don't take price or any other factors into consideration when evaluating prints, just how they look, but drawing a conclusion is another story. Simply put, if you are looking at stepping into your first DSLR, or if you need a solid back-up to your more advanced model, the A58 can be counted on in the JPEG image quality department across the ISO spectrum.
