Rumour has it that the next Sony Alpha SLT camera will have 102 cross-type AF points. That's not a typo.

According to the Sony Alpha Rumours blog, a reputable source has said that there are a number of prototype SLT-A99 cameras in the hands of photographers, boasting a 24-megapixel full-frame sensor. Also on the spec sheet is a brand new, 102-point autofocus system, all of which are cross-type.

To put this in comparison with other cameras, the Nikon D4 has 51 AF points, nine of which are cross-type, and the Canon 1DX has 61 AF points, with 41 cross-type. The A99 would be the top-of-the-line full-frame camera from Sony.

Cross-type AF points consist of two elements formed in the shape of a cross, which are generally more accurate when focusing on both vertical and horizontal lines.
