Sorry if this is a stupid question (I'm still learning) but is there any adapter out there that would make me able to use my EF-S lenses with the A7r?
The same Metabones mkIII adapter that allows EF lens use on E mount.
According to dpreview the sensor in the 36mp one is the D800 sensor.
Copy/pasting what I wrote in another thread:
It's not the same for a number of reasons:
1. Different bayer filter
2. Different electronics and signal processing.
3. Uses offset pixels to allow the use of short-registration lenses, without this most lenses would cause vignetting and color shifts towards the sides of the frame.
There's no doubt that Sony used their experience from the production of the D800/E sensor as a basis for this one, but it is quite different, with a year of improvements since then. Pixel offset alone is a significant re-engineering of the sensor, since each pixel cell needs to be gradually shifted in proportion to it's distance from the center. Additionally, the D800E didn't truly lack an AA filter, it had an AA filter an an additional deconvolution filter that supposedly undid the effects of the AA filter. This sensor may have been designed with no AA in mind. It remains to be seen.
