HVX200 overcranking with LEX? PLEASE ADVISE

Hey guys,

My first post here! :Drogar-Happy(DBG):

Hopefully this is in the right forum.

I've been hearing a lot about the LEX recently and its happened that a local rental company has offered me the use of one for next to nothing.

The thing is I don't have huge amounts of time to test my setup because I've only got the adaptor for a short period (including time to shoot).

Question is, I'd like to know if anybody has had problems seeing the vibrating ground glass shooting the hvx200 in 720pn mode at 36fps.

I'll be using the film mode which sets the shutter angle to 180. I hadn't planned to push the shutter speed fast because I'm shooting stuff that moves slowly in slow motion.

Any ideas if im likely to see ground glass or what to look out for?

;)
 
Hi Alex -
Depends on what you consider grain...I have shot 60 over 24 and found the grain to be acceptable. I have also found the grain to be unacceptable at simply 24pn. It all depends on what your tolerances are and what the particular project is.

I have found that increasing the shutter angel to 220 or more and always using fresh batteries can help blur the grain. Also, avoid large expanses of bright sky.

I say just go for it and check your footage before overcommitting yourself to 36fps.

Thanks for the advice man.

I'm happy with a little grain, but from reading around some people have been using the word unacceptable in conjunction with unusable with regard to this issue.

The scene I'm shooting is a recreation of a car smash. We'll be shooting this in early evening 'magic hour' sunlight, just before dusk. Overall grain could give the image a certain film-like quality, but I guess I'm just afraid of seeing the gg really noticeably.
 
Okay, showing my complete ignorance with the HVX200, when you mention 24pn, that is with regard to the 'FILM LIKE' setting that can be applied. If so I'll stick to the VIDEO option for anything over-cranked.

To cut a long story short my university literally just got a fleet of these cameras, but I'm still to have a good play. Luckily I have 2 days with the adaptor before my shoot to test things.

The other thing I wondered about actually was the ability to use zoom lenses with LEX. I've heard of other users having mixed success, having to re-back focus the adaptor when using the zoom.

I have access to a bunch of EF Mount Canon L-series lenses, a couple of zooms which cover most typical lengths, and also a 50-mm prime.

I planned to use these in place of some older, more basic, Canon FD primes. 28mm, 50mm and 85mm.

The rental company has mounts for both.

The only thing about EF that worries me is changing the aperture by switching the lenses back and forth between an SLR body and the LEX. Apparently its not so bad when you get going.

I guess I can use both interchangeably, but obviously some will create sharper images than others. :engel017:
 
Hey Alex, I use the Canon L series lenses and they look awesome. I use a few zooms, mostly up to 70mm, I used my 70-200 2.8 L and noticed reflections in the barrel
 
Cool. Sounds like sticking with the L-Series would be the best bet then.

As far as I'm aware (these aren't my lenses) I've got access to the following L-series glass:

10-22mm Wide angle
28-105mm (I think)
50mm Prime (Not sure what speed)
35mm Prime (Not sure what speed)
EF Macro Rings

I'll be sure to watch out for internal reflection though :)

I really want the image to knock my class mates socks off, the only reason I've opted to use the adaptor is to compress dof nicely because of the nature of the scene I'm shooting.
 
Cool man, the L lenses will definitely deliver the quality (I hate seeing people using old nikors claiming its "the same" lol)

I dont think 10-22 is an L :)
28-105 is an f4 but if your outside its all good!

the primes are awesome - good luck, be looking forward to seeing some footage, I don't know anyone else using the L series
 
Will get it on here asap.

Out of interest how do you find it having to the take the lens off the adaptor and shove it onto a camera to adjust the aperture?

Seems like a pain, but if its worth it I'm cool with that :laugh:
 
well compared to setting up HMI's and rigging the camera system on jibs and car mounts its one of the easier things to do:)

i really dont change the fstop too much, if I am indoors, its usually at the open end of the iris - outside I'll put it at a 5.6 or so to really get that sweet spot on the lens! its always good to use filters too if you need to stop down slightly in a hurry or whatever.

You can always stop down in camera slightly too
