Guest d5f8611fa423d0e628c016f9d5c93b47 Posted June 7, 2014 Share Posted June 7, 2014 Hang on. Is it possible to create a vari-ND that can be dialled to zero stops (i.e. lets 100% light through)? If not, my idea is stupid. Quote Link to comment Share on other sites More sharing options...
noone Posted June 7, 2014 Share Posted June 7, 2014 Seeing as we're currently in Speculation City, here's my chips: Built in variable ND filter! Fotodiox are doing it with their non-focal-reducer adapters. ND's work better closer to the sensor too. I agree that it's now a given that it's an active EF speed booster, and personally I would guess with a very fast/wide spec (0.2x?). This would pretty much make the GH4 a complete package to rival the C100. Built in IS would be insanely amazing but I think that's definitely a pipe dream. Why would Andrew use IS glass for the test if the adapter had it built in? He wouldn't, he'd use primes. If there is a fancy new feature my money is on a built-in ND filter. Metabones would do it properly with quality glass. It would sell in bucketloads. Panasonic would probably even pay Metabones to do it! In fact now I think about it Metabones would be insane not to do it. The only thing that makes me unsure is Andrew's review talks about him using the Heliopan ND. That could be a red herring I suppose, but maybe I'm putting a bit too much thought into this ... Metabones have said that .7# x is best for image quality and they didn't want to go to .5 though that could always change. EDIT the BMPCC speed booster does change that though. But I doubt they would go below .5x. Fotodiox said they were making a .5x Light Canon as well as a normal one to replace the failed light canon (now called a soft focus adapter).

Perplex Posted June 7, 2014 Share Posted June 7, 2014 Okay, its definitely a EF to MFT/GH4 speedbooster from Metabones. Look at the similiarity Here's a Nikon G to BMCC Speedbooster. Here's Andrews Picture Quote Link to comment Share on other sites More sharing options...
RubanCam Posted June 7, 2014 Share Posted June 7, 2014 By looking at the shots and the lens used, it is pretty clear some shots look like 24mm lens on a FF sensor. I think it is an active EF to M43 Speed booster which makes 0.5 X wider. So the Full frame rendering on the GH4 m43 sensor. Would love to see passive 0.5x Speed boosters for other mounts, hopefully for cheaper price since there are no electronics involved. Quote Link to comment Share on other sites More sharing options...
unconsenting Posted June 7, 2014 Share Posted June 7, 2014 If this adapter does expand to full frame equivalent, that would explain why he did not test the APS-C Sigma 18-35mm. Quote Link to comment Share on other sites More sharing options...

I tried figuring out the focal lengths as well but thought there wasn't anything wide like 24mm in it. Could be wrong though... Quote Link to comment Share on other sites More sharing options...

I don't know the character of the Sigma and Tamron he used, but I can't see any swirlyness/distortion in the far corners of the bokeh that would suggest all of the glass is being used. My guess is it will be something just short of full frame. Who knows ... Quote Link to comment Share on other sites More sharing options...
Kalamax Posted June 8, 2014 Share Posted June 8, 2014 I wouldn't go so far. My guess is a active adapter with super35 image rendering. And allready this would be more than great. Quote Link to comment Share on other sites More sharing options...

Luc Posted June 8, 2014 Share Posted June 8, 2014 Very nice video. It looks good on a 4K display. Downloaded the 1GB MP4 file from Vimeo (just need a free login account). Quicktime struggles a bit with it (it might be the 50Mbps bitrate), but VLC plays is smoothly. Can't wait to have a GH4 at the office. johnnymossville 1 Quote Link to comment Share on other sites More sharing options...

hellboy80 Posted June 11, 2014 Share Posted June 11, 2014 If you need an empty city for a postapocalyptic movie, you can do this with this camera at night :) Great footage. Inazuma and Andrew Reid 2 Quote Link to comment Share on other sites More sharing options...
unconsenting Posted June 11, 2014 Share Posted June 11, 2014 It is funny because I just noticed that the cover of the GH4 guide has a Canon L series lens attached to the GH4. I am not sure if it is a focal reducer though. Quote Link to comment Share on other sites More sharing options...

Tevan Shii Lockhart Posted June 14, 2014 Share Posted June 14, 2014 Tell us about the adapter you cheaky devil! Also hello this is my first post, I've been a reader of Eoshd for years but never joined the forums.

Inazuma Posted June 22, 2014 Share Posted June 22, 2014 Sorry to bring back a dead topic but Andrew, how did you get the slow motion shot at the end? Were you still using the same settings (24fps @ 4k, 1/50th shutter) but Twixtored to 25% speed? Quote Link to comment Share on other sites More sharing options...
jebbyderinger Posted June 25, 2014 Share Posted June 25, 2014 I just dont like the look of GH4. It looks too videoish... but the video posted by comurit looks really cinematic. It seems you can achieve the cinematic look even with this camera, but I like Sony A7s more. Do you like the still shots? I think the footage looks like video because of all the aliasing but it's probably a result of the uploading. The still shots from the video look a lot smoother and film like.
