Sony A55 / A33 video recording limited by overheating sensor
So this is why the promo video accompanying Sony's launch of the A55 and A33 was set against a snowy backdrop. It turns out that these oh-so-revolutionary translucent mirror shooters can't keep their cool for any longer than 11 minutes when recording video at a temperature of 20 degrees Celsius with Image Stabilization turned on. The A55 is even quicker to overheat at 9 minutes, though it's worth noting that with IS switched off you can obtain the maximum of nearly half an hour of footage -- provided the weather doesn't heat up. Sony blames this on the APS-C-sized sensor within, and it' true that plenty of DSLRs come with artificial time limits -- our D5000 won't let us get past five minutes however we try to sweet-talk it -- but it's an irksome limitation to consider if you're thinking of buying either of these Alphas for their otherwise awesome video capabilities.
Sony Alpha A55 makes articulating cameo, A33 and some rumored specs tag along
In the market for a Sony shooter or two? The company's upcoming lineup can't seem to stay off the internet, which lucky for you serves as a great source for planning holiday gift plans. First up the Alpha A55, pictured above with an apparent articulating display. According to the DChome forums, there's a 16.7 megapixel APS CMOS sensor, a translucent mirror, 15-point AF, 1080 / 60i video, 10fps continuous shooting, an ISO range of 100 to 25,600, dual memory card slots (we'd guess SD and MemoryStick), and an eventual retail price of $900 to $1,000. Also pictured on the site is the A33 -- with an unmoving display -- spec'd at a reported 14 megapixels, ISO range of 100 to 12,800, and 1080i video. The expected launch is August 24th, but bear in mind this all is just a rumor for now -- keep your wallet and check and don't do anything rash, k?
