Lens Height

My Next manual lens is probably Samyang 800mm f8 mirror, (Got a 400mm prime instead)
then maybe Samyang 85mm f1.4,(not necessary for that shallow dof as it totally blur away the background at f1.4)
then maybe Samyang 8mm APSC fish-eye (Bought for fun, and really fun, then sold)

As you can see, nowadays, only Samyang (re-branded Rokinon, Opteka, …) still produce good cheap manual lens.
