So i've been reading about image sensors (much of it is way over my head) but I'm doing my best to learn and I'm curious about foveon x3 image sensors or at least the concept with regard to video. From what I've read (and much of that is written by foveon or sigma itself so it's hard to know for sure) this sensor or technology seems like it might provide some real benefits. They "say" that it records more color information than regular sensors that don't utilize their stacked pixel sensors as it captures light at different wavelenghts with the use of different layers of silicon within the sensor itself and thereby captures "full color" at each pixel location. This all sounds really good to me but I've looked and haven't really seen any extremely positive reviews of either the sensor or cameras using the sensors. My main question is whether this sensor or concept might make a ripple in video imaging technology or if there are limitations that keep this from being a serious option for sensors in video.

Any suggestions what to do to to be able to do it all from the Iphone again without touching the GH5?

You could convert a normal camera direct output.

was testing out the clear image zoom on the a6500 to reduce RS for some handheld but felt the quality was off.

So I did a comparison, static wide with the Sigma 30mm f1,4 and the Sony 16mm f2.8 with 2x CIZ. Both at f5,6, shot in 4k.

And the later was indeed awful, see attached snaps (SOOC). Top is 16mm+CIZ, second is 30mm.

This is not even close to the good results I've seen of others' tests online. Any setting I need to change?

Here is my problem: since I switched to OSX "El Capitan" on my mac pro, my Final Cut Pro displays the rushes in a very dark way, as if there was a gamma adjustment problem. I tried to play with the settings of parameters in every way and I have not found a solution.

At best, the problem appears when the playback bar on the timeline is stopped. And as soon as I put in reading, the image appears as normal.

Any idea ? best regards

I just bought a really nice lens for a very good price due to the fact it has a few chips and scratches on the front glass.
However, the seller states it has no effect on the image quality.
So I received the lens (a Canon FD 85mm F1.2 L), and initial tests do not show any signs of the chips or scratches, which is a win for me.

Does focal range matter concerning if the chip or scratch will show up in the image? I'm sure for macro lenses it would affect, but telephoto lenses might be more forgiving.

Anyone's thoughts and experiences in using chipped or scratched lenses, please provide!

Also, my budget for a good wide is around 200$. if anyone can suggest me a better vintage/new/used lens i would be thankful.

Thanks!

• Good spacial properties, do not make moire
• Proper tone translation preserving subtle tone difference in reduced image.
• Preserving colors
• Preserving microcontrast
• High accuracy using FP calculations
• Good results with weird reduction ratios

• Works both with 8bit and 16bit images

I need some help choosing between the Leica 14-50 F3.8-5.6 and the Panasonic 14-45 (not the pancake lens). I already have the Leica lens and am thinking to sell it to buy the 14-45 for quieter operation but I am wondering if the 14-45 will produce a lesser quality footage than the 14-50. The IOS is noisy but my main question for this thread is the actual difference in image quality between the 2 lenses

If any of you have any experience using both of these lenses I would really appreciate feedback

Thanks

I thought the videos were good in the past. However, the lack of image stabilization, accurate Continuous Auto Focus, and a good wide aperture zoom lens were always mentioned as limitations with my videos.

Finally with the GH3 I think we are over that hurdle. The video below was shot entirely hand held(No tripod or monopod at all) by 1 person in continuous Auto Focus mode with the 35-100mm F2.8 lens. I also only used one battery and still had some juice left after more than 4 hours of filming.

I would say that the focus was spot on for pretty much every clip. Even the focus pull at the beginning from the guy’s Ipad to his son climbing worked perfectly. That was a one take shot. If I didn’t get it right I couldn’t ask the guy and the climber to go back and do it again.

I simply slid my finger from the Ipad to the climber on the camera’s LCD screen. I think it gave the video a very nice effect.

I had other lenses with me like the 25mm F1.4 and the 14mm F2.5. However, I never felt like I needed them. At F2.8 I was almost never above ISO 3200 even with the darker lighting they used for this round.

I think the IS was terrific in the 35-100mm lens as well. Yes I would rather have had the OMD’s 5 axis stabilization. However, I think this is the next best thing. Try holding a camera up for 4 hours straight with a 200mm 35mm equivalent focal length and see how shaky it is without good IS. I also like to take images while I record video and instantly upload them to the web so that spectators can follow along with the action with real-time pictures. With the GH3 I put it in the real time wireless upload mode and shot at 1080p @ 60 FPS in the stills mode. That way I could take stills during video and instantly upload them.

The only issue I had with that is that every time you press the shutter button to take a still it will initiate a focus adjustment. That actually made the focus go off more times than not. After noticing this I just decided to save images directly from the videos in playback mode(Press pause during video playback and then save an image). The camera will upload those images in real time as well.

I have tested the quality of images recorded during video recording and images saved during playback and they are indistinguishable in my opinion.

I also mount my GoPro 3 Black on top of the GH3 and shoot simultaneous wide angle 720p @ 120 FPS video. However, I scrapped all of the GoPro footage because it simply was not up to the caliber of the GH3 video. It is great for super slow motion but the 120 FPS mode indoors produces so much noise that it would not mesh well with the excellent video from the GH3.

I also was impressed with how well the youtube encoding turned out. I normally post to Vimeo as well because it is better for compression. However, in this case I thought the 1080p youtube encode looked great.

I didn’t alter the video at all. I did not do any color grading or post processing on it. I shot in scenery mode with -2 Contrast, +2 sharpness, Zero Color, and -5 Noise Reduction and simply pieced the videos together with a cheap($50) program called AVS Video Editor.

It was really nice to be able to produce the video with the footage as it was shot in camera and still get what I thought was a decent result.

There were plenty of other professional film crews there with much more sophisticated equipment. The little 11 year old girl in the last clip is probably the 2nd best female climber in the country(At 12 years old) and she has a film crew that follows her around everywhere she goes. I wonder how much better their footage looks?

So what do you think? Is the GH3 finally the camera that would make you put down the traditional video camera if you shoot both stills and video?

But a week ago, Google decided to launch a re-designed interface that hid most options, required more clicks, and move them to the top where they could only be used with an animated reveal (that you had to wait for) in order to make the desktop based image search more consistent with mobile use.

Worse still, the have "temporarily" removed the ability to specific "larger than" or "exact size" image options when searching. Now you can only specify three vague categories of size at best, and even that takes several clicks!

Over a 170 people have posted complaints in the last week in the official Google group at https://productforums.google.com/forum/#!msg/websearch/xcv50_kJ9Pc/ApEqKbCI8u4J but it may take a lot more for Google to get the idea people do NOT like having functionality randomly removed for no apparent reason and that desktop users do NOT like having their functionality impacted just to make things "consistent" with mobile users.

We couldn't stop Panasonic from ditching an MAR sensor, but this IS something we can do something about. Google has changed similar things in the past in response to public outcry.

This is the first time this happened to me. I have tried Disk Utility to fix it without success. Has someone had a similar experience or have a recommended application to fix the disk image?

Thanks in advance!

Edit: Price Drop $399

Hi - I'm selling my Panasonic 14-140mm Lens. It really is in perfect condition. I bought it new about 6 months ago and have used it maybe 5 times because I've been using only LOMO lenses since I got my GH2. It's basically been sitting in it's pouch inside the Panasonic box for 6 months. It comes with everything it came with when purchased new - Panasonic box, papers, front and rear lens cap, lens shade.

Great zoom range from very wide (14mm) to zoomed in very far (140mm). Lens has Optical Image Stabilization.

Price is $399 and includes free shipping if in US.

Thanks in advance
