@lolodigital: Hate to disappoint you, but GF2 does NOT have the GH1 sensor. It has the G1/G2/GF1 sensor, which is generally considered to be inferior to both GH1 and GH2 sensors, as well as G3/GX1 sensor.
Despite all this, I still like the camera a lot and think it was very underrated by GF1 owners who wanted a more significant upgrade. Definitely looking forward to what VK and Driftwood can make it capable of. Could be a very handy b-cam for GH2.
I was reading the test wrong. Apologies!! This seems a reasonable explanation. http://forums.whirlpool.net.au/archive/1586298
If I understand correctly, resolution doesn't affect DR as directly as it does detail levels. There is the conversion process and even the sensor pixel-site quality.
This is a great, detailed explanation of image sensor performance characteristics: http://www.clarkvision.com/articles/digital.sensor.performance.summary/index.html
Dynamic range = Full Well Capacity (electrons) / Read Noise (electrons)
Full well capacity is correlated with pixel area. So, for a fixed sensor size and construction, as resolution increases the DR decreases.
In this case it seems the pixel pitch on the GH2 is 3.6um while the GH1 has a 4.3um pitch. The read electronics may be slightly improved (less noise), but I'd guess it would not compensate for the drop in pixel size — so overall the DR will probably be somewhat worse than the GH1.
But strangely, DXOMark rates the GF2 as lower dynamic range than GH1.
http://snapsort.com/compare/Panasonic_Lumix_DMC-GF2-vs-Panasonic_Lumix_DMC-GH1 More dynamic range 11.6 EV vs 10.3 EV
Strange!!
Talking about sensor and only sensor here.
http://www.dxomark.com/index.php/Cameras/Camera-Sensor-Ratings/(type)/usecase_landscape
GH1 sensor: 11,6ev
GH2 sensor: 11,3ev
GF2= seems to be GH2 hardware/software with GH1 sensor ... I just hope for a better DR on a hacked GF2 ... :-)
Thanks vitaliy, I will wait till it pass the tests. Thanks a lot!
@zcream Doesn't Dpreview site you reference show that GF2 has more dynamic range than GH2? Much more range in shadows, and just a tad in highlight.
Where does it say that the GF2 has better dynamic range than GH2 ? This is a comparison stating that the GH2 has 1-stop more dynamic range (have not seen any tests though, so treat this with a pinch of salt). From snapsort More dynamic range Gh2 11.3 EV vs GF2 10.3 EV
From another site, again the GF2 has less dynamic range than the GH2. Use the dropdown in the graph to compare different cameras.
No it is not available. It'll pass via alpha and beta stages first.
Hi Vitaliy, I just saw in the version history that a 3.64d update with the gf2 hack. But I can't download it. Is it avalable already? Thanks!
@Vitaliy_Kiselev in the Stalin thread, about the new PTool wrote that:
"Most of the work had been to add some new features, and support for new firmware and GF2. As well as some preparation for fast GF3 porting."
This means that with this PTool the GF2 will have Video manual controls?
GF2 hack will open up the floodgate for mainstream. Cool.
@kihlian you took words out of my mouth!
@tonalt great deal! There are offers in NL with the 20mm?
For Europeans you can pick black GF2 + 14mm pancake only for €279 (~$367) (+ shipping outside NL) from cameranu: http://www.cameranu.nl/nl/digitale-cameras/panasonic/micro-ft-camera/panasonic-dmc-gf2c-zwart-14mm-pancake/h259_2053_171034/
So excited for this!
@tody, I can't wait either.
@driftwood, i am very interested to see what you can do to this gf2. can't wait!!
I'm gonna try pick up a GF2 tomorrow see if I can bring a few decent patches for it.
BH has them for as little as $380 with the 14-42
@drtygnus the GF2 is cheaper and probably better =) You can find some refurbished ones really cheap on ebay.
should i buy the GF1 or the GF2?
I'm interested in knowing too. I've been looking around the Lumix G series and have been quite intrigued with GF2 -- since I'm on a budget and planning on learning photography. I would love to donate to your work sometime and will await for info on a hack soon.
I used 2 GF2s and my GH2 (unhacked), with 4 EX3s and two MC50s. The GF2s at 17mbits cut nicely with the EX3s .. I look forward too the hack.
It was a 3 band concert, 9 cameras.
I'm really glad you are working on the camera. I've seen some HD video from the hacked GH2 and I was blown away by the quality and sharpness of the video. Do you think that increasing the bitrate of the GF2 video will result in something similar regarding crispness/sharpens ?
Hey when will this hack be ready??
@lensy in this sense?! http://www.lucavascon.net/blog/ sorry, italian only so use google translate... I think gf2 can shoot 3d video without tape...
