AF 100 verses Sony EX camera
-
WOW!!.
That looks amazing Peter.
The Ninja looks great too; the only think I don’t like is that is only HDMI.
I hate it for run-n-gun.

“I think soon will be many DOF adaptors on e-Bay.
rafael”Ha I think that’s been happening for the past couple of years already. I’ll go one further- it’s nuts to get a bolt-on DOF adapter in 2011. You can already get a better image easier with a sub-$1,000 DSLR. Times have changed.

Yep, in particular the Panasonic GH-2 – well, not really a DSLR, but EVIL. I like that acronym 😉

So in conclusion you’re saying if I had two HD cameras, one with a small sensor (with a DOF adapter) and one with a large sensor, there would be no difference in picture quality (assuming everything else is the same, codec, processor, etc)? So really the main advantage of using a AF100 over a Sony EX3 is that no DOF adapter is needed…and the larger sensor will perform better in low light. As far as the sensor issue goes am I correct in my thinking? Are there any other pros/cons to the big/little sensor topic?
One other thought: How does the viewfinder on the AF100 compare to the Sony EX3’s viewfinder? The EX3 is the only camera I’ve ever used and I absolutely loved the viewfinder. The one on the Panny is positioned different and looks inconvenient.

If you are concerned about the AF-100 viewfinder, then I would consider buying the Cineroid EVF to add on to your AF-100 camera. It’s about $800 to buy.

The main advantage is that you are not putting nothing between the lens and the CMOS.
The DOF adapter is stealing a lot of light that you need to compensate on your scene.[Mike Thomas] “Are there any other pros/cons to the big/little sensor topic?”
Bigger sensors need more powerful processors. You need to crunch all these pixels to 1920×1080 on the fly.
IMO this is one of the main shortcoming of DSLRs. They have not a processor optimized for video.
This is what some times makes horrible thing when shooting geometric patterns (roofs, tiles, etc).
Supposedly, the new “big-captor” video cameras has a processor optimized for the task.

…Just to clarify things, it’s the imaging sensor and how it’s data is processed that has to be optimized for video in order to eliminate aliasing and moire problems in the final HD image.
Canon DSLRs have problems because of how Canon chose to reduce the sensor resolution from 18 Mpixel ( Canon 7D / 60D / T2i ) or from 21 Mpixel ( Canon 5D MK2 ) down to 1080 HD resolution which is only 2 Mpixel.
The Panasonic AF-100 and Panasonic GH-2 both use optimized solutions to properly down rez the image to 1080 HD, so they effectively have little or no aliasing and moire problems.
…My guess is that the Canon 5D MK3 will also have a proper 1080 HD solution to get rid of aliasing and moire.

Hi Guy,
Alister Chapman made some interesting tests.
I can not find the original article.
This one miss the pictures where he shows the aliasing issues, but I think contains the full text:https://www.hdwarrior.co.uk/2010/03/12/alister-chapman-dips-his-toe-in-the-murky-hd-dslr-water/

Thanks for the link. I expect Canon will fix all of it’s video problems with the next generation. 5D MK3 looks like it will be the first with new Canon tech, I just don’t understand why Canon is taking so long to fix this. ( I recently sold all my Canon gear and switched to the GH-2 )
