kc_moses 142 Posted February 12, 2014 I'm interested to switch over (formally a Canon 7D user). I'm wondering does anyone know if it's possible to use Canon lens on the GH3/4 body? I think there are some made in China adapter that only let you to manual focus wide open aperture non-electronic adapter. But I'm looking for Speedbooster kind of adapter.

Ferg42 13 Posted February 12, 2014 I'm interested to switch over (formally a Canon 7D user). I'm wondering does anyone know if it's possible to use Canon lens on the GH3/4 body? I think there are some made in China adapter that only let you to manual focus wide open aperture non-electronic adapter. But I'm looking for Speedbooster kind of adapter. I've been having the same thoughts. I looked into it and it looks as though the metabones speed booster is not yet available for Canon EF to M43 mount. But they do seem to have one planned- see here: http://www.metabones.com/article/of/faq On ebay you can also get adapters that are manual focus, but have an iris built in for aperture. Not much use underwater though. Share this post Link to post Share on other sites
kc_moses 142 Posted February 12, 2014 Yeah the ebay stuffs are not going to cut it. I forgot, probably have to check my lens are not EF-S. Share this post Link to post Share on other sites
kun1 10 Posted February 12, 2014 Has anybody seen or heard of a release date yet? I'm heading to Tiger beach last week of March, would be great to take with me... Share this post Link to post Share on other sites
thetrickster 328 Posted February 12, 2014 Last week of March... You might be lucky with that. Depends on preorders I would think. It's 'weeks' away. Not months. So fingers crossed. As to adaptor. Don't think they would fit in the housing. Plus if you are manually focusing. The ring wouldn't fit - if you have a speed booster in the way. For underwater use. You're gonna need m43 lenses.

With those lens the only option is eBay Actually I guess they have a huge market. A little bit OT but an amazing future new entry for uw use Share this post Link to post Share on other sites
CheungyDiver 53 Posted February 13, 2014 The oly.7-14 is amazing zoom lens for 4/3. A bit pricy. I have used the. 12mm f1.4. Great lens for my BMPCC. With the m4/3 mount there is no shortage of adapters. I have tried tonnes of Nikkor Ai lenses. Some provide really nice images. 8 bit 4 2 0 is not going going to cut it for me. I hope housing manufacturers going to consider all the peripherals needed to make this a real contender for UW 4k. I would not dismiss Sony yet. 3chip cmos 4k may be soon. One can dream.

Cheers The GH4 outputs via the HDMI, an uncompressed 10bit 4.2.2 signal (although internal recording is disabled if you record in this mode) So (like I have) if you are using a Ninja2 (in a NA-NINJA2 housing) - you will be able to get 220Mbps 10Bit 422 ProRes straight off the camera.

Davide DB 606 Posted February 13, 2014 Or even better... GH4 has already internal 1080p 444 recording. It is just the 4K itself! When the camera will be out it's a matter of time and simple convert utilities will appear. They will make 444 lossless formats out of 4K videos. Share this post Link to post Share on other sites
Ferg42 13 Posted February 13, 2014 Don't you need that massive block on the underneath to get 4:2:2 10 bit 4K? but you can get 4:2:2 8 bit from the built-in HDMI, or am i misunderstanding? In either case, is there an affordable external recorder for 4k yet? and if so are we going to get a housing for it? Questions, questions.... Share this post Link to post Share on other sites
Davide DB 606 Posted February 13, 2014 (edited) No, read the previously posted presentation in PDF. You just need a micro hdmi cable and an external recorder as well.

Davide DB 606 Posted February 13, 2014 I continue with this little OT because Oly officially presented the lens showing a mock-up. Real lens will be out in 2015 M.ZUIKO DIGITAL ED 7-14mm 1:2.8 PRO lens The new splash and dust-proof M.ZUIKO DIGITAL ED 7-14mm F2.8 PRO is the first wide-angle zoom lens in the M.ZUIKO PRO series to cover 14-28mm**. Not only does the compact and lightweight design of the lens portray the well-known ZUIKO Quality. Its excellent depictive power and the superb clarity from the center of an image up into each corner of the picture are another highlight of this outstanding new Micro Four Thirds lens. http://i1266.photobucket.com/albums/jj524/picrumors/picrumors001/0071_zps6ee9e0a3.jpg Share this post Link to post Share on other sites

No, the 4k 10bit 4:2:2 signal is available straight out of the side HDMI port - no need for the brick. Alas the only underwater recorder (with HDMI) at the moment as I'm aware is the Ninja2, and that is 'limited' to 1080p30 4:2:2. HOWEVER with 10bit 4:2:2 - you are limited to external recording ONLY 8 bit 4:2:2 - you will be able to record simultaneously (both to SD, and have uncompressed 8bit to the HDMI port) The 'Brick' is mainly for XLR and SDI outputs.

Sent from my iPhone using Tapatalk Yeah the Canon lens is going to be used for land base only, of course for UW use I will have to get m43 lens that work with the housing and port. All in all, I have $2500 worth of Canon lens with filter etc. So if I could use those lens, it would be ideal. Share this post Link to post Share on other sites
kc_moses 142 Posted February 13, 2014 BTW, you know what's missing in the GH4? 5-axis Image Stabilization (http://panasonic.net/avc/camcorder/features/hybrid_ois/) !!!!! Well, at least it's not being mention. On the side note, I got feedback that color accuracy for Panasonic is not as good as Canon/Nikon. What's your thought?

Nick Hope 151 Posted February 28, 2014 Two questions... 1. Has it been confirmed that the PAL and NTSC framerates will be included within the same body (i.e. a world camera, unlike GH3)? 2. Based on previous releases, what would be the best-guess timing for availability of the camera and a Nauticam housing? Share this post Link to post Share on other sites
Davide DB 606 Posted February 28, 2014 (edited) Hi Nick. #1 yes. it's not clear if the infamous 30' limit will be in all camera when you switch to PAL mode... #2 All reviews say that the body it's exactly the same as GH3 except two things: * A 2mm larger eyecup that can be removed. * A lock mechanism on upper part of the right wheel. hence a GH4 could fit in a GH3 housing immediately or a modification (NA-GH3 MarkII) to accommodate both camera from nauticam shouild be trivial. EDIT: A GH4 user manual leaked confirming that you get 1080p 4:2:2 10 bit or 4K 8 bit out of micro-hdmi without the brick. In the meantime Edited February 28, 2014 by Davide DB Share this post Link to post Share on other sites
thetrickster 328 Posted February 28, 2014 I would think the 29.59min limit will still be in place on European models - its a Tax issue - so I would they will likely keep it and keep the price lower. I'll be ordering mine from B&H Photo from the states. Will get full 1080p60 still and no limit. Share this post Link to post Share on other sites

kc_moses 142 Posted March 3, 2014 Emm....... still looking for the answer: Does the GH4 has Hybrid O.I.S? If it does, is it like the GX7, which only applicable in photo, but not in video mode? Guess we will have to wait for 2 more months until more reviews show up! Share this post Link to post Share on other sites
Davide DB 606 Posted March 3, 2014 No hibrid OIS ala gx7. OIS is only on lens. Camera ois is not possible on video because sensor heating. Olympus has it on omd-em1 but it has limited frame rate and nitrate. Share this post Link to post Share on other sites
