Having black curtains in the background will certainly give one dark bokeh.

Overstock has them BTW: Linky... I have seen them there for less, so maybe a sale will come soon.

Is Overstock reputable?

The "f1.8" is what I question. If that was the case, then I would have difficulty achieving critical focus at f1.2, and I don't.


You will only have difficulty with lenses that shifts focus. Like I said, try the DOF preview. You won't see any difference between f/1.2 and f/1.8.

So I assume the Maxwell treated screen is supposed to transmit more light while at the same time maintaining a true, accurate representation of the lenses aperture?


I have no idea. The grain on the screen surface can be designed in many ways, but you'll always lose some light with slower lenses, if the screen should show the DOF of large apertures. There simply is no light falling in at those angles with a slow lens. Think of the surface as built up by very small prisms, allowing light to fall through at different angles. Every little grain has its own angle, and a very bright screen has only prisms at steep angles.

I don't know if it's a location thing with my "logged in" account with Amazon but I can't find any in stock at $248. The wife orders frequently from Overstock and she's even returned a few things and their customer service seems good.

Not sure if this has been asked or not, does the lens have any in mid-step f-stops between 1.4 and 2 i.e. does the aperture ring detent any between say f/1.8?

Thanks,
Roy

It has half-stop detents between f/2 and f/22, no detent between f/1.4 and f/2.

One can still put it at roughly 1.8 even if there isn't any detent.

Or one could make their own detent.

Love my Rokinon. Hate the hood! Can anyone recommend a suitable replacement?

Yes. Get a knock-off of the Nikon HN-20 metal screw-in hood. This hood is for the Nikon 85/1.4 and goes for $32 at B&H http://www.bhphotovideo.com/c/product/37602-REG/Nikon_562_HN_20_Lens_Hood_72mm.html , but you can find Chinese or Hong Kong knock-offs on e-bay for about 1/3rd to 1/2 of that price.

For example, I bought this one from this dealer: http://cgi.ebay.ca/New-Metal-72mm-Screw-In-Lens-Hood-For-Nikon-HN-20_W0QQitemZ160427569472

It is perfect.

Found the Rokinon on Amazon from Cametta for $249.00 plus $9 s&h...got it!

Thanks Cogitech, got the Nikon HN-20 knock-off for $13 and change shipped.

I also ordered the EE-S Focus Screen for the 5DMK2 from B&H.

Can't wait!

Does anyone use ND filters with this lens and it so which ones? I'm actually considering an ND-Fader, this one: http://cgi.ebay.com/Fader-ND-Filter-adjustable-ND2-ND400-72mm-/140360763906?cmd=ViewItem&pt=Camera_Filters&hash=item20ae274a02

A lot of people like these for video, but I'm not sure about stills? I know I would use it for video. Also, I'm not sure how a filter would play with the hood.

I would find it hard (and possibly boring?) using a prime for video.

It would prevent over-use of zoom, which is good thing, IMO. Zoom-abuse is a sure-fire way to create "amateur" videos.

To my knowledge fast primes are prefered in the DSLR video world.

Not much of a video authority, but a +1 anyways. I would think a fast prime could take better advantage of the full-frame sensor and separate one's work from the usual handy-cam type movies with it's limitless DOF.

There's no point to using DSLRs for video (instead of HD video cameras) except in low-light conditions, so I guess that would make sense to pair it with a fast prime.

Yes, I can see your point there, but then you go to the other extreme and are locked to one FL with a prime.

The assumption, if you are shooting with a dSLR, is that the scenes, lighting, lenses, focus, etc. are planned out well in advance (as when movies are made).

If you are going to shoot "home videos" then get a handy-cam with an 800x zoom lens and go nuts.
