Rokinon 85M-O 85mm F1.4 Aspherical Lens for Olympus – Review:
ROKINON, SAMYANG, VIVITAR, OPTEKA, ETC!
I have the Rokinon version of this lens. It is great! I use it on a Nikon D700 and have compared it with the Nikon AF 85mm f/1.4 (which I had rented for a weekend to test) and I much prefer this lens to the Nikon.
When I used the Nikon AF version, I found myself having to manually focus to get the plane of focus just where I wanted it and so decided I really didn’t need to pay extra (almost a $1k more) for the AF feature. So the only thing that would make sense for paying more was if the Nikon’s Image Quality was significantly better… it wasn’t. In fact, at f/1.4 (which is where you will be shooting this lens 99% of the time, else why buy an f/1.4 lens) I found the Rokinon/Opteka to be sharper and have more contrast than the Nikon.
There are a lot of reviews to be found on the inter-net for this lens. Some express concern for obtaining a good “copy”. I am sure this lens is not as consistent in its build quality as Nikon is, but I got lucky right out of the chute with my first one. It is amazingly sharp, mechanically sound, and the IQ is just what I needed it to be (bokeh is wonderful).
Bought mine through Amazon from Cameta Camera. Great store with quality customer service.
For the price, you really can’t go wrong.
