Also posted this at dpreview, but thought there might be some interest here as well.

After reading some very encouraging reviews and user reports on the
Rokinon 85mm f1.4 lens (manual focus, manual aperture), I decided to
pick one up to try it for myself. I picked it up from Overstock.com
for $245, and you can find them at B&H, Amazon, ebay, etc for around
$250-$300 - certainly an attractive price for an 85mm 1.4. The lens
is Korean made, and can be found marketed under Rokinon, Polar,
Samyang and a couple other names.

Here's a link to one of the threads over on the Nikon SLR board that
originally caught my interest:

dpreview thread

The build quality is pretty good - nice solid feel, looks good, and
the manual focus ring is easy to use. Aperture is set on the lens
via a ring, and is easy to use. With the a700, the camera always
reports f/1 in exif, but it does meter correctly in A and M mode. It
ships with a hood and a faux velvet case.

The lens is very good optically - sharp wide open, with surprisingly
good bokeh. Minimum focus distance is about 3.5 ft - wish that was a
little shorter. My only real complaint so far is that manual
focusing is harder than I thought it would be! I'm hoping I get
better at it with more practice, because when you nail the focus,
this lens delivers really good results.

Here are a few test snaps from last night - all handheld, which is
really, really difficult with such razor thin DOF :)

The sharpness looks good, colours pleasant, and the bokeh is excellent. Certainly seems to be a good way to get a wide aperture 85mm at a good price. Yes, my manual focussing experience on the A700 with the SMC Tak 50/1.4 (manual focus) is very much hit and miss, and it appears that this lens has the same drawbacks. Nevertheless, I think it's worth persevering to see how your manual focussing success rate improves over time because when it works, the results seem to be worth the effort.

Does it work with SSS and focus confirm?

SSS - yes (the second shot is 1/30, and I have a few with even slower shutter speeds).

Focus confirm - unfortunately, no, unless I'm missing something. I think this lens might be great on the a900 with its incredible viewfinder. I may also look into a different focusing screen for my a700 to help with manual focus, but not sure I want to go down that road yet - it's something I know absolutely nothing about at this point, so will have to do some research.

standard focusing screens are not very good for manual focus. There are third party screens with a split prism that are said to help achieve fine focusing, like in a SR camera.
In the range of spare screens at Sony, there is one (can't recall what it's named though) that is designed for MF, but without a split prism.

Thanks Frank - I was pretty optimistic about the optical quality of this lens from the Nikon thread I referenced, and I haven't been disappointed on that front. But I definitely need to improve my manual focus skills Hopefully, that gets easier with practice!

Is there a chip on this lens? (to allow for focus confirmation and correct SSS value)

Actually, there isn't. I answered the question about SSS above, but now that I think about it, I'm pretty sure my answer is wrong. SSS seems to help to some extent, but the camera does not get the correct focal length from the lens, so it may be that I just have steady hands :)

There's definitely no focus confirmation.

And is there space left to glue a chip? My guess is that some people might be interested by this lens in chipped configuration.

edit: spelling

It shouldn't be too hard to put a chip into the lens though. It will cost ~$50 and some time, but I think will pay dividends with the resultant enjoyment.

Here is a site showing how to install the chip. I doesn't look hard, but will require a bit of time. Note that this isn't showing the 85mm lens in question, but the procedure should be almost the same for any lens:

From this image shamelessly stolen from an ebay auction, there appears to be anough room for a chip. However, this may not be a Sony mount. Perhaps Keith can show us what the rear of the Sony mount looks like?:

Thanks for sharing your results Keith, the photos you took are fantastic despite being challenged by MF. I've been temped by this lens myself since my hopes of finding a minolta 85 1.4 for less than $500 are fading fast. I really wish sigma or tamron would make a 85m f1.4 with AF and I'd gladly pay $500 for one.

Yes I agree, the Vivitar looks bad. The others, Bower, Rokinon, Falcon, etc, all look like the one below, and not as ugly as the Viv. (Also stolen from ebay):

It's manual focus and aperture. It's like an MC Rokkor lens with an alpha flange.

There is no mechanism in it to provide any readings to a chip.

There are no electrical contacts, assuming that it is in fact the same as the Vivitar.

So you would have to add much more than just a chip.

AE works (in A mode) because shutter control is in the body.
