MP resolution but also came with a maximum ISO of 25,600, live view and a 1080p HD movie-mode, making the Sony look a little weak in the features department.
Sony’s answer came, with a slight delay, in August 2009 in the shape of the DSLR-A850. Rather than upping the new model’s feature set Sony decided to leave the A850 (compared to the A900) almost unchanged and compete exclusively on price. The new model is available at a RRP of $2000, making it the cheapest full-frame DSLR currently on the market. Obviously something had to be done to justify the price difference to the flagship A900 (and not completely annoy existing A900 owners), so Sony decided to differentiate the A850 from its bigger brother by slightly reducing the viewfinder coverage and the buffer size (the latter resulting in a 3.0 fps vs 5.0 fps continuous shooting rate). All other key features remain unchanged and are listed below.
