G9 Digital Teleconverter
4

About 6-7 months ago, decided to try out the digital teleconverter on the G9.  While the 4X doesn't appear to be worthwhile, the 2X when using the PL 100-400 provides up to a 1,600mm field of view.  Anyone else try this? Here is an example.  For me it works to get shots that may not be possible.

Re: G9 Digital Teleconverter

A feature on almost every Panny cameras.

It can be useful if I do mot have the long lens with me. The Digital zoom can use with Extended Tele Converter for a higher zoom effect.

In case if you set at S size of image, it would do the same as Extended Tele Converter @2× effect and no software interploration will be carried out to preserve the original IQ of your camera. I shall use ETC more rather than DZ on my 16Mp pannys.

That is a very nice photo! We had a long thread about using the DTC with long telephotos last year with many interesting posts in the thread and many example photos also:

I notice that you shot your 100-400mm at 187mm so with the 2x DTC that is a pseudo 374mm. I am wondering why you didn't just set the 100-400mm to 374mm without the DTC, which, of course, would have been much higher quality and easier to boot?

Re: 187mm x 2 = pseudo 374mm

Hi Henry:

I was panning at various focal lengths and did not have time to change.

After I posted I figured it was probably something like that.

I had the same experience as you, except with the PL 50-200mm lens. I wanted to see how good the DTC was on my G9, so I set up test shots, first with no DTC, then with 2x DTC and then with 4x DTC. I was surprised at how good the images were with the 2x DTC. Almost as good as with no DTC. However, the images from the 4x DTC were pretty bad. You definately should not use that. But the 2x DTC with the PL 50-200 is more than acceptable and very sharp.

Would this not work better with cropping and using TOPAZ Gigapixel to increase the image size?

Not trying to sell TOPAZ - seems better than resizing with bicubic algorithm, though.

Perhaps it would, but I do very little PP. Just the little that I can do using Apple's photo app. Anyway, I am quite satisfied with Panasonic's 2x DTC, just don't use the 4x version.

The cameras have access to the raw data before demosaicing so we don't know how they do their interpolation. Do they do it using the mosaiced data? Do they do it demosaiced data?  And what algorithm do they use?  Is it possible they do bicubic on demosaiced data?  Yes, but probably not.
