#367580 Making The Leap To 4k Pro. Please Help.

Posted by kc_moses on 27 November 2015 - 07:01 AM

On the other hand, with the LX100 you need to use a port system with a short port that has a smaller zoom range. It lacks the Sony's 1080p120fps mode and its HRF mode (really nice 240fps and more specialized 480fps and 960fps) It also doesn't have a pop-up flash and the housing is significantly bigger. And, perhaps less important for underwater footage, but the RX100IV has a log mode, whereas the LX100 doesn't. 



Yes, there is no perfect camera out there. The initial discussion of this thread is "leap into 4K" so 1080p features are not really that relevant unless we're having a discussion solely about RX100 vs LX00, which there is plenty of videos in youtube to show that. BTW, LX100 is now $699 at B&H, that's a whole lot of bang for the bucks.


Log, yeah, it's another big discussion. Do you want to endure the work flow of color grading? What is the quality after grading (trying to grade a 100mbps 8-bit 4:2:0?) For log, it's best to go ask those GH4 shooters. From what I have seen, log and color grading is ok/good with the Atomos Shogun as the GH4 put out 10-bit 4:2:2 4K. Gearbow would also need to find out if his clients would want log video.

Before you go with the Sony RX100 M4, make sure you understand its short coming. You can't do custom white balance when shooting video, how would one improve video skill without learning white balance? If the camera require shooter to slab on a red filter and leave the white balance to auto, it's just a glorified GoPro.


I use Panasonic LX100 and it gets the job done with reasonable budget. Even though it uses port system, the Nauticam N50 port system is reasonable priced compare to interchangeable M3/4 and dSLR. I was going to move into the GH4, but I can't justify spending $200 for a piece of gear for the lens, and if I have a few lens, then the cost of gear add up, not to mention dome etc. Using the port system on the LX100 also prepared me mentally should I move into higher end camera in the future if I want to go with dSLR or m3/4.


Here is one of the clips of the LX100:

Posted by kc_moses on 23 November 2015 - 02:31 PM

The LX100 is a mini GH4, it has excellent MWB, perform slightly better than the RX100 M4 in term of macro, and is cheaper. If wide angle is your thing, then just get the short port and the WWL-1 then you're all set. With the WWL-1, you get around 120/130 degree, remove the WWL-1 at 24mm, you get around 70 degree FOV, and when switch the camera to macro mode at 24mm, you can focus up to 5cm. These 3 technique in the flat port itself is very useful.

While I do not know which camera (Canon or Sony) was used in the natural light shallow shots, CC applied seems very close to the Dustin video mentioned above. Great video!



That video is done by one of my friends (Lee), he uses Canon 6D, often white balance on a white board attached to a loc-line attached to the top of the housing.

When in doubt, upload video to both Youtube and Vimeo. You can reach more viewers in Youtube and more commercial works sit in Vimeo because it get separated from all the cat videos :D.


The video in Youtube have improved a lot. I recently bought a 65" 4K TV, I stream my own 4K video as well as Eunjae Im's "Living Color" to see how everything look on a big screen. The detail holds up, color banding is not as bad as I remember 6 months ago. So I think Youtube have done something recently. The RX100 IV 4K underwater sample shot in Taiwan looks very very nice by the way and it's stream from Youtube. I thought it beat the GH4/LX100 if not neck and neck. But it's subjective and really depends who're behind the camera to bring out the capability of the camera.


Also, Vimeo streaming is hit and miss, sometimes you get stuck with buffering, while Youtube may look crappy and pixelated when it's buffering at least you see something play back instead of a spinning wheel or as if the browser is not doing anything when Vimeo is buffering. Youtube search feature is also quite accurate. Keep in mind also many people are starting to have a Smart TV, and Youtube channel player is almost standard for all the Smart TV. So when I got my big screen tv with smart tv feature, I don't have to plug in a computer or do any setup, just launch the Youtube app, search for a clip and play back, just like using a Playstation.

Posted by kc_moses on 16 September 2015 - 06:31 AM

Yeah, I can see the difference:



But damn it, the price! I wonder what make the high CRI light so expensive, even light for land use! May be it's just one of those things like OLED TV, that will never get to general public's hand for a very very long time!

Got my V-Log!!!!! Now I wish they could give that to the LX100 as well :dancing:

Let's put a bet, have they fix the Custom White Balance Error issue? If not, no point to use it for video :lol2:

BTW, some one should invent a device to pump helium into the housing. Wouldn't that help with life the rig? :lol2:

Congratulation for getting the LX100! I hope you enjoy it and replace your NEX5 with it. Do you have the dome port on? It looks quite wide.

Just use the information here:




Order the foam from here (choose Type H100): http://www.aircrafts...inycellfoam.php


I made my own float and spray paint them red, then use those strong vegetable (broccoli/asparagus) rubber band and tie it together :lol2:

There are some news and update about the SteadXP, but it's a bit disappointing since it's going to be 6-8 months out:

Nice work! Did you get a hang of the focus system behind the dome port on the LX100? I can't help but notice, there were a lot of divers!!! Flash everywhere, were you on liveaboard?

#362085 Sony RX100 IV 4K - Control Set?

Posted by kc_moses on 10 June 2015 - 06:30 PM

Are you using it for video or photo? If you're using it for video, the LX100 has advantage of more zoom range because of the crop factor so it's better for macro. You will also need to pay attention to the custom white balance of the Sony since they're known to have issue when come to custom white balance for video.


For photo, the LX100 has larger sensor, not sure what Sony's 1" stacked sensor translate to in term of quality. One thing to keep in mind is the RX100M4 is more expensive, the street price of the LX100 is $799 these days, $200 cheaper than the Sony. Other things like built in timelapse on the LX100 vs ND filter on the RX100?

Finally! There is another 4K diving video!!!! I was just wondering, there are so many GH4 shooters out there but I only saw EJ from Korea upload video in 4K. I guess you have been missing in action. The song is catchy, anyway you can add some tambourine track because it could really use one.
