![]() In our A350 review we commented how the A350 can benefit from increased sharpening, but only at the lowest sensitivities. It’s revealing that noise or processing artefacts are already visible at 200 ISO if you’re looking for them, and they only get worse, smearing fine detail as you increase the sensitivity. This is the first 14 Megapixel APS-C DSLR we’ve tested and if it’s resolution is not already a step too far, then it’s certainly as far as you’d want to go before sensor technologies or efficiencies improved. The one to really watch for here is the Alpha A350. ![]() The A300, and its predecessors exhibit higher noise levels at 400 ISO and above than the 10 Megapixel Canon EOS 400D / XTi, and from the crops below, the 12.2 Megapixel EOS 450D / XSi is holding onto more detail than either Sony model at higher sensitivities. It’s also important to look outside the Alpha world at how both cameras compare to the competition. Judging from the crops below we’d say the A300 has a slight edge over the A350 at 200, 400 and 800 ISO, but it’s certainly not like night and day. The big question though is how the A300 compares to the higher resolution A350, as many hoped its lower pixel count would result in a camera with lower noise levels. Jump to 1600 or 3200 ISO and these become obtrusive. Like the A200 though, noise and smearing from processing artefacts are creeping in at 400 ISO, and these really kick-in at 800 ISO. As such you’ll enjoy clean, detailed images at 100 and 200 ISO. The crops are taken from an area just below and to the left of the centre and presented here at 100%.Įmploying the same 10.2 Megapixel sensor as the A200 and A100, it’s not surprising to find the A300 performing essentially the same here. The image above was taken with the Sony A300 at 26mm f8 and with a sensitivity of 100 ISO the original JPEG measured 3.99 MB. All lenses were set to f8 in Aperture Priority mode and adjusted to deliver the same field of view. To compare noise levels under real-life conditions we shot this scene with the Sony Alpha DSLR A300, Alpha A350 and the Canon EOS 450D / XSi within a few moments of each other using each of their ISO settings in Aperture Priority mode.īoth Sony’s were tested using the same DT 18-70mm kit lens, and the Canon 450D tested with the EF-S 18-55mm IS kit lens.

We will update this page with samples from a retail A300 when one becomes available. Note: Sony has asked us to describe our A300 as a pre-production model, although supplied in retail packaging and running Firmware version 1.0, we’re confident the output is close or even identical to what you’ll get with final production units. ![]() Outdoor resolution / Studio resolution / Real life Noise ![]()
