I'm sure I've reviewed this before. This is used on my Sony A77. The pictures are stunning and 1.4 it is very fast with great bokeh. It is a manual focus lens but I love manual focus so it suits me. As my pro snapper friend said it's the best 85mm manual lens he has used. It is what you wouls call "engineered" it's heavy, beautiful and made incredibly well. If it was auto focus it would cost at least £1,200 in my opinion.
