Sony decided to focus on their telephoto line of lenses before turning to tilt-shift so, for now, you really have to rely on the third party options available to you. Until that time the Lensbaby Sol 45 f/3.5 Tilt-Shift is a good inexpensive option to practice with that is relitively compact. Lensbaby even released a step by step guide which you can read here about how to do tilt-shift photography.
Create unique-looking photos with the selective-focus SOL 45 f/3.5 Tilt-Shift Lens from Lensbaby for Sony E-mount cameras. With 8.5° of tilt, this lens lets you easily isolate a subject within the frame and surround it in blur and smooth bokeh. The lens also features a center-locking feature that will lock the lens into place for dead-center focus. Furthering its creative potential are two adjustable bokeh blades that can add slight lines or textures to bokeh. This manual-focus lens also has an all-metal construction and accepts 46mm filters.
