I recently had a chance to shoot video at the US Youth Sport Climbing Nationals along with several other people. Myself and one of the competitors were just shooting handheld home movie style for our own highlights videos. However, there was a crew there who was hired to shoot the official Highlights video. Since there are so many climbers not much was overlapped between all of our videos.

I used my GH4 mostly but I always had the GH3 running as a backup with a wide angle lens in case I missed something. The other person was using a Canon T5i and the camera crew had full frame Canon cameras with rigs and stabilizers.

It is pretty obvious that the extra time the camera crew put in for editing paid off. The overall editing of their video is what they really get paid for. However, I was really surprised at how different the Canon video looks to the Panasonic video. Even on youtube you can see that the extra bit rate that the original file has shines through. You can also see that the Canon cameras consistently clip the highlights in almost every scene. The GH4 only clips it in the scenes with direct sunlight shining through the windows.

The video in my file was completely ungraded. It is straight out of the camera and just pieced together with the music. I started out shooting 4K @ 30 FPS because I wanted to see if the extra resolution would allow me to do image stabilization in post processing. I quickly realized that while the extra resolution is a plus the slower Auto Focus was a HUGE minus. With these shots the kids are moving constantly and changing direction during falls.

You can see in the T5i video how often the focus goes out and comes back in. You really need good AFF for this type of video. Therefore, I switched to 1080p @ 60 FPS with a 1/120 shutter duration and 1080p @ 96 FPS for slow motion.

I liked the fact that I could do super slow motion with the 96 FPS footage. However, there is a severe resolution drop when using that 1080p mode. In the end I found out that the 1080p @ 60 FPS mode really is the most versatile. It simply never loses focus and it still has significantly more resolution than any of the Canon cameras. It also retains all of the highlights in creative movie mode with the Cinema D setting.

So what do you guys think? Everyone complains about the Panasonic cameras having 13 stops vs. 14 stops, or the lack of All-I for 4K, or the rolling shutter not being fast enough. Does that really matter? Isn't the significant resolution difference and compression artifacts of the Canon cameras a much bigger issue? Yet the professionals still shoot with the Canon cameras and get paid for it.

So what do you like about the videos below and what do you dislike? I for one love the shallow depth of field of the larger sensor cameras. Even the mighty 35-100mm F2.8 doesn't give me the depth of field I would want on the GH4. However, I wouldn't trade that for the lack of resolution.

Videos:

Amateur T5i video. Remember to select 1080p in the youtube player for highest quality.

Amateur GH4 and GH3 video. Mostly 1080p @ 60 FPS, with some 1080p @ 96 FPS, and 4K @ 30 FPS. Remember to select 1440p for highest quality.

Amateur GH4 video. Almost all 1080p @ 60 FPS. Remember to select 1440p in the youtube player for highest quality.

Professional Canon full frame video(I think. Could be APSC as well). Remember to select 1080p in the youtube player for highest quality.

On paper the specifications and level of A6000 seems better. However in my experience with the NEX-5N even consider Sony in color reproduction is some steps below respect to M4/3 (in FF is another story), the A6000 has greatly improved with colors, but I dont have seen a video that me is convincing in paragraph colorful as offering GX7, which seems a kind of mini GH4, si I do not understand that the manufacturer block the HDMI output when recording video.

If you were to stay with one camera between these two, with which you stay?

Anyone out there happen to have any dealings with them recently? Or possibly know of another place one could send a lens mount like this to get repaired?

Thanks guys!

If this material ever escapes into the wild it could improve the performance of our lenses and cameras.

Any answers, including specific things or just gear categories are ok.

Until now, HUD displays in cars looked like text sitting on the windscreen. Now it appears to float in front of the car.

The head-up display, which Mercedes-Benz is introducing into its first vehicle model as of 2014, takes this to a higher level. The system provides data on vehicle speed and speed limits, and issues navigation instructions and warnings from assistance systems. The ‘head-up display’ supplements the information in the instrument cluster. As in modern day aircraft, important information is reflected onto the windshield, directly in the driver’s field of vision, ensuring drivers are less distracted away from what is happening on the road ahead. Furthermore, the eyes do not have to adjust between distance vision and short-range vision, because the information seems to hover above the engine hood some two meters in front where drivers can absorb it without having to avert their gaze or make optical corrections.

Perhaps with similar but wearable technology (a la Google Glass), city streets will no longer be filled with pedestrians looking down at their phones?

Same thing apply for any big item you sell or just ship.

The patches Driftwood manage to make, how he handled the matrices 4x4 no 8x8 matrices...dammnit even 2x2 if its possible on h264, the difference its clear. The looks is clear.

Please vitaliy, opening a film stock world again by hacking this Gh4 beast is something good for the masses.

Its not about performance any more, its about better image.

Of course if you have a hungry amount of clients which needs the up to date quality then you will make enough money to pay the investment, but if you are in a not so high end market then you can survive with average gear.

a7s and gh4 with small improvement in dynamic, range bitrate and codec, raw cameras with headaches workflow, flat images with difficult grading in post... rolling shutter in a 2.5k usd camera!!! fixed pattern noise in cmos sensors... so why not stop buying new cameras and try to extract the best possible from old dslr and mirrorless until a great tool comes to the market? this is what I am trying to do, to hold down my excitment about gear and focus in other things... I believe in a great audiovisual job with humble gear instead of expensive gear and so so results in terms of what is going on in the screen and audio.

there will be the moment when 4k retina displays will be popular, 4k streaming will be spread over the world with fast internet connections for everybody, 4k projectors in all theaters instead of 2k cinemas. 16 fstops dynamic range will be default, so it will be the time to get a powerfull camera with new sensor technology.

the sensor technology we have today cannot deliver so much dynamic range. it is a waste of time to try to get enough DR from silicon cmos without two streams merged or without the promissing quantum dots or organic sensors. in soccer broadcast we can see the stadium with sun and shadow in the grass and the high end cameras cannot show both with enough dynamic range... So the manufacturers try to implement gamma profiles to improve DR but the post grading will not be capable of recover gamma and contrast and keep so much fstops at same time... oh my god, do not ask me to work with raw workflow, it is a headache...

It is time to extract milk from the rocks, to deal with limitations. to put the camera on tripod to avoid aliasing, moire and rollling shutter perceiving, or to use a camera with good enough capability to a handheld job without showing so much artifacts...

I perceived that the old T3i with the vaf filter is good for camera movements because the aliasing in power lines is almost unoticeable, the magic lantern hdr is better dynamic range than all new cameras in the market. it is a matter of how to use it avoiding the motion artifacts and doing a careful sharpening and upscaling in post. the gh2 still rocks for resolution and all you need to do is to add light or reflectors to the shadows, old sony nex are amazing with focal reducers for wide angle and DR is good enough for a low budget camera.

I am addicted to gear, I keep researching about all new camera release, but suddenly I perceived it is a waste of time... Just a new sensor technology will change the game. I think the thing to do now is to do something amazing with old obsolet gear.

The lens is actually at a repair shop, which is how I know the flex is the problem.

But the repair person stumbled upon the problem that there is no orderable part number, and it is not showing on ebay.

So he basically told me that if I couldn´t find the part, he could not do the repair.

Panny already replied this lame answer:

Dear Pedro, I am sorry the Flex Cable is not supplied as a service part.

Am I to assume that for an $20 buck part I will loose a $500 lens ? Remember I am in Costa Rica, son not many local or even regional options... please guys a little help!!!

Thanks!

According to USPS they delivered the package on May 5 , this is the date I have dont received the lens, as my freight forwarding company they have not been notified or received the package by USPS , the package seems if the zip code, but not delivered, in UPSPS site dont appear who signed the package delivery, I have written them for send me a scanned image or photo of the invoice and they dont have answered.

I reported to Amazon but as the package appears as delivered they are not responsible, equally USPS, equally my courier, the seller equally but I pay U$455 for an article I dont have.

I'm just shortening for give you an idea of the problem . This includes almost U$50 in international calls I made ​​to USPS without success.

I have thought about the possibility in demand to USPS and freight forwarding company in Miami, but I dont know if this is legally possible

I bought by amazon many times and never had this problem.

I still have my kit lens and my (dare I say, beloved) Panny 100-300. Not ready to upgrade to the GH4 yet.

Wanted opinions on what the cheapest replacement would be from the Lumix lineup? Would like 60p video, but not a deal breaker. Mostly for nature photography with that lens. Were any other camera's hacked besides the GH2?

thx

I'm gonna be a father, i have just received the grate news, me happy and wanted to share it with the community.

I'm very exited and nervous cos i never had children, and well, im the last of my family...so.... never carried even babys! maybe twice.

Any advice?, the deal is done!
