Jamie, don't say stuff you don't know shit about, lol.
Nikon, C/Y, M42, R, OM and T2 are all adaptable to Sony.
Sony has great lenses (Zeiss made), they just don't have a big variety, which I think doesn't really matter because they have enough good ones. They just lack big telephoto's, which nobody on here uses anyways and a TS lens, which will probably come with Samyang's TS.
They have a 24, 35, 50, 85 and 135mm prime (the last which is a f/1.8 which both Nikon and Canon don't offer) and 16-35, 24-70 and 70-200 which are all Zeiss made.
Sony gets way too much hate in the DSLR world. While they absolutely kill it in the video world, their DSLRS are great too.
