Where did you get that information from?

Yes, both of those lenses are fixed focal length lenses (also known as 'prime lenses'), one at 35mm and one at 50mm equivalent field of view. So, you can't zoom with them, you can 'zoom' with your legs though. Difference between the two lenses is in focal length.
There's no such thing as which lens is better suited for which body (apart from the Nikon D3/5xxx case where you can't AF with lenses without in-built motor). It depends more on what purpose you want the lens to work as. Do you need a wider or a narrower view? Go to the stores to test it out. Borrow the camera from a friend who has it and test it out if possible.
If you are really unsure of which to get and worry that you might get the wrong one, then just stick with the kitlens that comes with the camera for the mean time while you improve on your camera knowledge before investing in a prime lens.
It's stated in the manual.. I put my 50mm on and it really changed to contrast AF.Added on October 18, 2011, 12:30 am

that if you use the MF liveview check thingie. normal QLV using phase detect.
Oh. I'll try to set phase detect to default. Thanks.

I've updated the front page regarding the A77 and wireless flash.
8tvt: Yes it is written on the package.
There is also a Sandisk Class 10 30MB/s but you don't want that for the A77.
e-jump: Nice! Love how the reflection is blurred out.
fansoption: Nice! It almost looks like a texture.
Newbieeeeee:
PDAF = faster because it knows exactly where to go once it has looked once
CDAF = slower because it keeps adjusting and checking
By nature the PDAF sensors are getting light that passes through the main mirror, reflects off the secondary mirror, into the AF chamber. The distance from the lens to the PDAF sensors should be the same as the distance of the lens to the sensor.
If not, you get a backfocusing/frontfocusing camera!
PDAF on sensor (which the Nikon V1/J1 supposedly has, but where are the tech documents?) solves this. Since there are no TWO distances, there is no misfocus from calibration error.
CDAF, because everything happens on the main sensor, does not have backfocusing/frontfocusing issues.
The A560/A580 uses PDAF in Quick AF Live View, and allows you to choose between PDAF and CDAF in Focus Check Live View.
oh okay! Thank you for answering my noob question! 8tvt: Yes it is written on the package.
