Panasonic Lumix GF6 interview, something missed

Postby PalaDolphin » Wed Apr 10, 2013 2:33 pm

Dear Gordon Laing,

Great informative interview http://www.cameralabs.com/reviews/Panasonic_Lumix_DMC_GF6/. It sounds like you know more about Panasonic's product line than their UK product manager Barney Sykes. :oops: I especially like the expression you evoked on his face when you asked if this was the same sensor as the GX1. :lol: However, I seem to have missed part of the interview.

About 11:00 minutes into the interview, just after you asked about the lack of phase detection used in AF, and before Sykes recommended you join their engineering team, you mentioned some technology that didn't come out on audio quite so well. Maybe due to microphone placement, rapid pace of talking, or my utter inability to comprehend an English accent, I couldn't understand what you were asking him? And I played it back three times.

Sykes seemed to be impressed and interested in what you had to say. So, could you please, for us, tell us what you were talking about?

Thanks in advance.

While we're on the subject, sausage recognition? Don't you Brits call it bangers? I'm trying to imagine what a food creative filter would be doing, some kind of sustenance white balance? :lol:

I presume you're referring to the GF6 recording video in 1080i, like its predecessors as opposed to going 1080p. 1080i has the benefit of using less bandwidth (generally speaking) to produce the same video resolution but because frames are scanned twice (compared to just once with 1080p), the video may not playback as smoothly as that shot in 1080p, particularly with fast-moving subjects.

It's a slang term some of us use but "we Brits" can't be tarred with the same brush.

No, I'm referring to the interview video.

I listened to it again and right before Sykes asks Gordon to join the engineering department Gordon is asking if Panasonic have removed the low pass filter. Sykes told him that they haven't and Gordon informs him that moire is not a real problem, not even on the 16Mbit Coolpix A. According to Gordon removing the low pass filter gives a clearer picture and allows users to get a step up in image quality without having to spend a lot more money.

Is that what you meant PalaDolphin?

I got that but I realise I misread what you put slightly. Like cujo said the low pass filter is probably what you couldn't understand.

The Nikon D800E is a good example of it where the D800's anti-aliasing filter was changed to remove the low pass filter effect so images are considerably sharper if at the expense of increased (albeit slightly) moire.

Yep, cujo's got it!

I was talking about removing the low pass filter in front of the sensor which is traditionally used to slightly blur the image to eliminate moire. By removing it, you run the risk of moire but also enjoy sharper images.

Moire is where you see fine patterns or lines become merged with often coloured effects. You can see it on TV when people wear stripy ties or shirts.

Check out our sample images pages for the Nikon COOLPIX A and Nikon D7100 and Fujifilm XE1 for examples of cameras without low pass filters.

Yes, as you said the Panasonic Lumix GF6 review was too good for the people who want to know about it's features. I have seen the video in the Youtube last night. The review explains very well about the Lumix GF6 features and I am very much impressed with the product after watching the interview.



Thanks
Lourene
