All cameras
after the Dynax 9 ( and only upgraded Dynax 9's) are compatible with SSM lenses .
So the Dynax 7 , 5 , 4 , 40 , 60 ( AKA Maxxum 50 & 70 ) and 3 series models are fine with both the Sony / Minolta SSM lenses and Sony SAM lenses .
Sony bought the Minolta camera division well before 2009 .
In 2006 they entered the DSLR market with the Sony a100 ;

This was my first DSLR that I bought in 2007 to continue using my Minolta lenses on digital and was essentially a Minolta Dynax 5d with a new sensor and more streamlined body .
There are a few generations of lenses .
1 ; 5 pin models . compatible with all A mount cameras from the Minolta 7000AF of 1985 to present day .
2 ; 8 pin Xi Zoom and Power zoom models . Introduces with the Dynax 7Xi of 1991 . compatible with all cameras after this date to present day . Not a lot of use with cameras before then as the extra pins in later bodies added a power supply to the lens .
3 ; 8 pin "D" lenses . When Minolta came up with ADI flash control ( rather than TTL flash ) they added a distance encoding chip to the lens to report back subject distance to improve flash . Good for direct flash but useless for bounce flash where TTL OTF flash is reverted to .
These lenses are fully compatible with all cameras from 1985 to present day as long as they are gear driven and not SSM , regardless of how many pins are on the camera body .
4 ; 8 pin SSM lenses . Sony and Minolta . These are the lenses that have a motor in the lens for AF and will only auto focus on compatible bodies from the Dynax 7 onwards plus upgraded Dynax 9's .
With all earlier bodies you have manual focus only .
5 ; 8 pin SAM lenses , Sony brought out a cheaper option to SSM lenses here . compatibility is the same as SSM lenses .
I've used the Sony 85mm f/2.8 SAM on my Dynax 5 and 7's and it works well .
Be aware "DT" lenses are for APSC crop sensor only , but some cover the full frame ( film ) at some focal length's O.K .
Some of the later APSC crop lenses from Sony have dropped the "DT" marking , something to be aware of .
Regarding Minolta "G" lenses and drive , only the last version of the 300mm f/2.8 G and 70-200mm f/2.8 had a SSM drive , all other Minolta "G" lenses had a gear drive .

Sony carried these on , and other Sony G telephoto lenses are also SSM .
Such as the 35mm f/1.4 G are still gear driven by the camera body .
