lens series differences

Is there a description anywhere describing the differences between the different pentax lens series? For example what is the difference between FA and DA?

Basically, FAs are full-frame lenses with aperture rings (except FA-Js that don't have aperture rings) and DAs are APS-C lenses without aperture rings.

F and FA lenses are similar in function but the Fs tend to be a little heavier built and possibly better optically. FA J is an econno grade lens , remember J is for Junk. DA "s are "digitally optimized which means that they only have to transmit an image the size of the sensor rather than a full frame 35mm image if you want to use it on a film body it will leave 2 black bars at the ends of the picture.
All the above mentioned will work fine and fully functionally on the digital bodies currently available.

It is alittle confusing at first but read the threads here and ask questions but like I said yesterday , start with 1 good quality lens and get to know your camera then build your collection.
