any good wide angle/ fisheye options for 4k?

[Etienne Caron]

since the 4k region on the sensor is Academy 35mm (smaller than 35mm still) and all our 35mm lenses will seem to have longer focal length, it will be tough to get the really wide and/or fisheye shots that I really like for some of my EFP work. Are there any adapters out there that might work well attached to, say the Nikkor 17-35 ?

I'm asking myself the same question... my Nikon AIS are great and Zeiss ZF would be more great... but with the 1.62x factor, its kind of useless if you want "wider" shoot".

My choice is:

Nikon 12-24mm f/4 DX

or

Nikon 14-24mm f/2.8 AF-S (NO DX, so you have to apply the 1.62x)
http://www.kenrockwell.com/nikon/14-24mm.htm


The 14-24mm got really really good reviews, but there is no filter thread. So you have to use a matte-box with filters... its no big deal when you're shooting fiction. But my purpose of having this lens is to shoot documentary too and got to find a way to fit some "thread" into the sun-hood and fix some circular ND.

Do you think that the motor of the 14-24mm's (using Birger to focus) will make some noise that will bring weird look from a sound guy ?

thanks

Since the RED has a sensor that is the same basic size as the "Digital" DX or APS-C size of many DSLRs there are a lot of lenses available in the still world - specific to the digital size sensor (won't cover full frame) but perfect for the RED. If you go with birger nikon or canon mount you have

Canon 10-22 which is rectilinear and sigma recently introduced several fisheyes - in both full circle on the RED sensor size and fisheye but not full circle.

I think Sharky is right - there really aren't any adapters that would give you real good 4K results AND that Arri 8R is AWESOME.

Please note, "DX" or no "DX", I have always seen DSLR lenses listed by their true focal length in mm, not some kind of scaled focal length as the above quote seems to imply.

It is an interesting lens, is it shipping yet? I have yet to find any actual images from it.

Oops, here is one. Apparently, the circular image diameter is 12.3 mm at the focal plane.

MM is MM

MM is MM

jbeale is right, focal length is focal length. You only apply a conversion so you can think of the equivalent angle of view on a different format - so when thinking of RED or an APS-C DSLR like a Canon REBEL or 20D,30D,40D - you multiply by 1.6 to get the equivalent on a full frame SLR.

But if you are comparing the 10mm of the 10-22 to a Zeiss PL mount 10mm on RED it would be the same.

THE DX or EF-S designation only tells you that it won't cover a full frame Digitial or film SLR, the millimeters are still the same.


Don't know if the 4.5 lenses are shipping.

How about the Kinoptik Tegea 9.8mm? It's a wonderful lens and I'm sure it covers 4K with RED.

Anyone got a confirmation on this?

I'm offered a deal on 3 lenses:

-35mm ZOOM ANGENIEUX 25X250mm Arri B mount for 3000$
-35mm ZOOM ANGENIEUX 20X120mm T 1:2.6 Arri B mount for 4890$
-35mm Super Wide Kinoptik 9,8 mm Retro-focus (110° field) with matte and casing for 1600$

Does any of this sounds interesting or is this looking for trouble? Would I need adaptors? Which?

I heard the Kinoptic is quite fun and good, and I checked the clip posted here... Rather cool rendering!

I'm thinking on getting the Red lenses anyway, but this might widen a choice of focals? My goal would be to have all lenses PL ready... Is this possible?

Kinoptik 9.8 covers 4k fine, impressive correction of distortion you could say it's a bit retro in the contrast dept. Center resolution is good, edge resolution? - we'll you can't have it all for this cheap!

Instead of those old Angenieux's you should look for a cooke 25-250 Mk2 and a 20-100 - much better lenses at similar prices.

Thanks Matt! Although I assume from the lens scouting I'm doing that the Cooke are MUCH more hard to find nowadays... And I'm pretty sure the Red hype has got something to do with it...
