Below are some patterns of labeling for Sony lenses:
SAL --Sony alpha lens
SAL####Z
Z for Carl Zeiss-- the legendary lenses, #### shows the focal range
SAL##F##,
F for fixed focal length lenses or prime lenses, first ## indicates Focal Length, second ## indicates largest aperture
SAL##M##,
M for Macro lens which are normally of fixed focal length, there are zoom lenses with macro label on them but they don't delivery the 1:1 magnification fixed macro lenses do
SAL####G,
G for Sony's high quality premium lenses. respect
SAL##TC
TC for teleconverter
SSM for Super Sonic Wave Motor
eg.70-300mm F4.5 -5.6 G SSM
Non-full frame lenses are marked with DT after SAL####, you can find it on the description pages of the DT lenses. No DT means full frame
eg.SAL16105 DT 16 - 105mm F3.5 - 5.6, you can find this on lens barrel as well
Full frame lenses are those without DT in their descriptions or on lens barrels
Sony seems to have made an effort not to distinguish DT lenses from full frame lenses when they are listed on the same webpage.
