Sean Davey Photography: OK, I'm a long time Canon user. I want to know if I buy one of the converters out there will I be able to use my Canon EF lens full frame on the new A7R or will there be fall off on the edges?... I'd really like to know a clear and concise answer from someone who actually knows from experience... Thank you.
Just in case you're confused, FE is not a new mount. It is still the same mount as on NEX cameras, it's just that the old NEX lenses designed for APS-C is slightly impaired on a FF sensor
I really love the yellow markings on that lens
yabokkie: a little bit embarassing
flipmac is talking about light transmission. An f1.8 lens in ff will transmit the same amount of light in APS-C etc etc. This is the reason why people describe a lens with a smaller f-number a faster lens, since it lets in more light hence you can use a faster shutter speed to get the same exposure.
Rather you are speaking of depth of field equivalents: flipmac talks of this in his second paragraph
xc1427: I am confused by the Hybrid AF ability of the 50 f1.8 and 30 f3.5 lenses. In the extended review of NEX6, which is just posted before, it is claimed that "Note that this hybrid AF technology is not compatible with any of the fixed focal length E-mount lenses except the high-end Sonnar T* 24mm F1.8 ZA. And existing E-mount zooms will require a firmware update.".
I suppose it's because it wasn't supported by the firmware at that point in time, rather than a physical limitation per se. I don't know anything about optics and such, but that's how I interpret it
