3D lens test

[jonnycom]

Hey, we are in the process of testing a bunch of glass for the purpose of seeing how they perform with 3D. Primarily checking on distortion, tracking, nodal issues. We are testing RPP's, 16-42 Optimo's, Ruby's, Red 17-50's and the new Lecia Primes when we get them.

We ordered our 17-50's a while ago but have not received them. Does anyone know where we can rent 2 of them or have one that we can test?

Anyone have any ideas for a 3D lens test?

Thanks

I'd recommend Primes ONLY. and then if you are shooting parallel or beamsplitter

[jonnycom]

we will be shooting with our Omni Rig, a beamsplitter. Why primes only? It seems like most 3d is being shot zooms.

most the tests i'd been involved with ruled out zooms and in fact we went with matching zeiss primes. Found that trying to match the zooms was not a full proof method. Who is shooting mostly zooms in 3d?

I think a lot of feature type shooting is done with zooms to avoid having to reconfigure the mirror rig all the time. Easier on high end systems to get it aligned once and then change focal lengths as needed on the fly.

i Have one as well as TVC nashville does. I cant speak for TVC but I will gladly rent mine

just send me an email.

To switch lenses in 2D takes minutes, in 3D it could take an hour. Zooms, while not as well matched as some prime sets can be, are used in 3D projects to cut down production stalls on set. The optical differences in zooms or primes are negligible with a DI suite in the pipeline. And if you are not headed toward a DI, you should reconsider shooting in 3D.

We shot a TV Pilot using the the Omnirig with Masterprimes and were very happy with the results. Lens changes took maybe 5 minutes at the most but use a great AC familiar with 3D and the rig. We have also used the 18-50mm Red Zoom and not so thrilled as focus tracking was poor and geometry average.

We have also used Canon and Fuji Zooms with success and some of it for live TV with only minor issues. Geometry is definitely not perfect but for a football game on expanses of grass not so bad.

Geometry issues are not so frightening especially if you are going to use Ocular within Nuke or something similiar.

We started using older lenses such as Zeiss Superspeeds but they were very average with frightening geometry shifts especially in the wides. Most quality modern glass will get you in the ballpark and if your rig needs an hour to change lenses get another rig.

Paradise f/x seems to be having no problems with a matched pair of Angenieux optimos on their 3D rigs.
