![]() The camera’s dynamic range is a shade less than the Lumix S1R at ISO 1600 (9.6 stops) but compares favorably to the Nikon Z 7II, which dips below 9 stops at ISO 1600.Īs for color reproduction, the lab found seven colors deviating strongly from the original, including two purples, a blue, a green and two reds. At ISO 1600, the Alpha 1 delivered 9 stops of dynamic range and down to 8.5 stops at ISO 3200. The Alpha 1 can achieve a maximum of 10.5 f-stops at ISO 100, slightly behind the R5 but besting the Lumix S1R and Nikon Z 7II.ĭynamic range will contract a bit as you scale up the ISO, which is typical. That’s comparable to the performance of the EOS R5. Switch to printed output, and the Alpha 1 didn’t show visible noise at any ISO value tested. That said, both the Lumix S1R and the EOS R5 will start to display visible noise in this viewing condition at lower ISOs. The Z 7II images, for instance, wouldn’t show visible noise when viewed at 100 percent until ISO 3200. Lower resolution (but still high pixel count) cameras tend to fare better at controlling noise. Images will show less noise if you set the camera to “High ISO Noise Reduction – Normal.” Images won’t show noise at 100 percent until ISO 1600 and even then it’s “barely observable.” Considering the high resolutions at play, that’s no small feat. ![]() ![]() Image Engineering found the Alpha 1’s noise control “decent” when viewing images at 100 percent on a display. Texture reproduction is good at low ISOs, but declines “fairly rapidly” as you start to push the ISO. Again, though, it’s significantly behind the EOS R5, which can still resolve 100 percent of its theoretical maximum resolution at ISO 6400.Īccording to Image Engineering, the Alpha 1 does lay on the sharpening, particularly along high-contrast edges. At ISO 6400, Image Engineering found the A1 resolving 85 percent of its sensor’s theoretical maximum,delivering about the same resolving power as the Lumix S1R or Nikon’s Z 7II. The Alpha 1’s resolution stays above 90 percent at ISO 400 and drops to 88 percent at ISO 800. It’s on par with Panasonic’s Lumix S1R and Nikon’s Z 7 II, but lags Canon’s 45-megapixel EOS R5, which is capable of resolving 104 percent of its sensor’s theoretical maximum. The Alpha 1 can resolve 96 percent of its sensor’s theoretical maximum, a good, if not outstanding result for a camera with this many pixels packed into its sensor. You can find a full rundown of the Alpha 1’s specs here. According to Sony, you can enjoy recording times up to 30 minutes thanks to a body design optimized for heat dissipation. In addition to 8K/30p recording, you can capture 10-bit 4K footage at up to 120p or output a 16-bit RAW signal from the camera’s HDMI port. With 9.44 million dots and a refresh rate of 240fps, it sets a new benchmark for mirrorless EVFs.Īs for video recording, the Alpha 1 joins the slowly expanding ranks of cameras capable of recording 8K video. The Alpha 1’s in-body stabilizer is good for 5.5 stops of shake reduction.Īnother notable advancement debuting in the Alpha 1 is the high-resolution electronic viewfinder (EVF). The AF system supports real-time Eye-AF for humans, but also animals and birds. This faster-than-a-Hollywood-movie frame rate can be sustained for up to 155 RAW images or 165 JPEGs while the camera performs both autofocus and auto exposure tracking.īeyond its blazing speed, the Alpha 1 boasts 759 AF points covering 92 percent of the sensor. At 50 megapixels, it’s not shattering any resolution limits, but the combination of its resolution and continuous shooting speed is something to behold: the Alpha A1 is capable of capturing 50-megapixel images at 30 fps. Every once in a while, though, there are cameras where these evolutionary steps look more like a leap.
