Lenses?

[Steve Gibby]

What types of lenses will you use for your EFP/ENG work?

Any specialty lenses?

Wide adapters and converters?

B4 2/3" and/or adapted cine lenses?

Follow focus or zoom servo, or both?

Brand lenses you like? Why? For what type of shooting?

Matte box or no matte box?

Filters you prefer? For what type of shooting?

I am hoping my 16x6.3 fuji HD lens will not take too big a hit with the conversion or windowing. I have not really been able to crunch the numbers
since I cant multiply on my fingers and toes.

[Steve Gibby]

The field of view (FOV) on B4 2/3" HD lenses will be narrower when they're used on RED One. I expect zoom-through wide converters, and partial-zoom wide adapters, like those made by Century, 16x9, Cavision, and Red Eye to be commonplace on the front of B4 2/3" HD ENG zooms that are used on RED One. Everyone will be seeking to widen the FOV back out, and in the process shorten down the minimum focusing distance. They'll also be handy for increasing DOF, if needed for certain genres of shooting. Hopefully those types of converters and adapters will come down in price...converters can be pricey.

Got that right Gibby. Ever check out the price for a Zeiss Aspheron converter for the 18mm Zeiss prime?
Ouch

[Steve Gibby]

No doubt...microeconomics and economies of scale definitely in effect there!

Moderate demand + low supply = high price

----------------------

With the B4 2/3" converters and adaptors the model is more like:

High demand + moderate supply = high price (In this situation I believe supply is artificially kept moderate or low in order to justify a higher price)

Hi Gibby
Maybe I'm really wrong here, but talking to Les Z, I had the impression that the FOV was the same when using the Abakus converter. Supposedly it corrects the 3chip related problems.... and stretches the target area over the S16 size frame optically.

If it actually didn't do that and simply looked at a S16 size windowed sensor with a B4 lens, which was designed for 2/3" then it would probably vignette at the wide end anyhooo???

I would imagine the RED converter will work the same way...Or maybe better since it costs $500 more?

I have a very nice 18X plus doubler Canon HD zoom which I will use for these kinds of assignments. These clients expect the range with the doubler so S16 lenses would just be dissapointing to them. I do own a wide eye zoom through converter, but the end of the Canon HD lens is so large, about 100mm that it won't fit so is relegated to my old reliable Betacam.

I dont know how we can avoid using a matte box at least a light clip on because of the need to drop in ND filters.

TJ,

First off let me just say I don't know what the optical design of the Abakus is either. I would assume that since it is correcting for chromatic abberations that I "hear" occur when using those types of lenses in a air space optical path, I would think that it is more of a relay type optical group then anything else. But I also believe if it increases the diameter of the circle of coverage, that it must have a power to it (albeit a small amount). Therefore I think that there is a magnification factor to the unit.
Then again I could be full of you know what!

Let me add this for what it's worth; Traditonally converters were refered to as optical groups which mounted on the front of the lens and could be either plus or minus in power, and extenders mounted betwen the lens and camera and were always plus in power. Unless they were a 1 to 1 relay lens.

What types of lenses will you use for your EFP/ENG work?

I'm hoping the Red 18-85mm will be the workhorse for my above water material from interviews to establishing shots etc on documentary shoots.

Any specialty lenses?

Ya, I have a deposit on a Zeiss 10mm prime for my underwater system and I will rent prime sets and longer zooms as required for clients and projects.

Wide adapters and converters?

I think not in 4K?

B4 2/3" and/or adapted cine lenses?

PL mount until I see results from other solutions.

Follow focus or zoom servo, or both?

Exterior f8 and up not necessary in doco work. Obviously yes for Red DP work on other projects. (Hey, I like the sound of Red DP).

Brand lenses you like? Why? For what type of shooting?

Zeiss, Cooke, Arri primes due to 4K underwater wide angle requirements and for edge to edge resolution on Mysterium - until I see or test other solutions?

Matte box or no matte box? Filters you prefer? For what type of shooting?

Definite yes for polas and ND's exterior day - interesting to see if tobaccos, promists and the like compare to digital rendering of looks in post?

[Milan Nikolic]

Set of Nikor primes and RED 300 mm for starter.

[Jared VanLeuven]

I'll be swapping out that PL mount for the Nikon as soon as the camera's unboxed. I'm extremely grateful for Evin's Nikkor tests.
