AF100 / AF101 - initial report

yes, i know what kind of strobing you may mean. when you pan its like the image cant keep up to the camera and is jumping to catch up as you pan. HDV i found has this problem as well on the 7D as thats the only HDSLR i have tried. if this is evident, which i dont think it will be, it will not look nice on pans. barry, could you confirm this on what you have seen thus far.

i am also interested in the adapters. is this something panasonic will have available or are they already made by other companies? i would be using nikon mount zeiss mainly. i just hope its a beefy adapter and not a slim metal piece that wont hold the lens tight after a couple lens changes(as do many DSLR adapters do making FF work useless).

Thanks Barry, great coverage and a good read over here,

-also for some upclose images of the camera. looks solid thats for sure, and the CP.2 lens looks very nice on it.

Which is why I call the crop factor a "crap factor". It just causes confusion. I say ignore it and instead think in terms of a cinema prime lens set, which would include a 25mm, 35mm, 50mm, and 85mm. Those are the most common focal lengths used in cinema shooting. Who cares what the lens looks like on a still camera? You're not using a still camera, you're using a cinema camera, so use cinema focal lengths. An extended cinema set would add 18mm, maybe 21mm, and 100mm. With those 7, you've got a pretty complete set.


Correct, but almost irrelevant. The cinema crop factor is so minor that you can just about ignore it. I mean, if you put a 20mm lens on a cinema camera and shoot from 10 feet, you could get the same results on an AF100 by either a) using a 23mm lens, or b) use the same 20mm lens, and shoot from 11.8 feet back instead. Really it's no big deal. It's very slightly different, but it's not some big scary thing you have to worry about. You just use either a very slightly wider lens or set the camera very slightly further back.

Sorry, i just could not understand that yet.

Is the crop factor about 2x or not? To achieve the 50mm FOV, do i have to use a 25mm lens ou not?

This a lot confusion for me as this stills make me wonder if it was better to invest in a full frame camera.

Thanks for the infos Barry!

The sensor is definitely not the same as the GH1. All the fixed-pattern noise and vertical streaking are GONE, the noise performance is better, it's just better in all ways. But the sensor is the same size as the GH1; it's not bigger than the GH1's, but both the AF100 and GH1 sensors are bigger than the standard Four Thirds chip. They're about 19mm wide, instead of the Four Thirds standard of 17.3mm.

if your reference is full frame, yes its 2x
barry's point is, dont get hunged up on focal lengths. just know that the lower the number, he wider it is.

Ok here's the deal. Full frame dslr sensor sizes are bigger than cinema 35mm. So if you are comparing a 50mm lens from a full frame still camera, then yes it will be 100mm on the af100. But if you are talking cinema lenses - a 50mm will pretty much behave the same.

Hey, at 2:16 there's a CGA-D54s battery (the one for 100/200/170s series) at the back of the AF101.
Still anything for sure about the battery type, then?
I have Hpx171 and I would be very happy with CGA type...

Thanks bob, so what about the lenses we can buy?
How can i know the diference between a cinema lenses and a dslr lenses? The 50mm canons for example... how they act on a m4/3 sensor?

Yes, the 50mm lens will be 100mm on the AF100 in terms of framing / FOV, but that does not mean the 50mm will magically share the DoF characteristics of a ~100mm lens. I think it's important to keep this in mind. In other words, if you like the way your ~100mm lens looks on a full frame still camera, slapping a 50mm lens on your AF100 won't approximate what you got from your ~100mm lens on a full frame setup. I think Barry's basic reasoning is that you shouldn't overthink crop factor. Get a range of primes or a suitable zoom lens that covers most the basics (e.g. - from ~14mm through ~85mm) and you'll likely be happy with the latitude and results.

I might be horribly wrong about my interpretation of crop factor, so somebody please chime in if I am.

You have the right idea for sure. I think people have become really confused with all the different sensor sizes, but I think people really need to focus on the comparison between s35 and 4/3 size. The size of s35 film and the 4/3 sensor are so close that it is negligible to even really worry about the math. Like Barry suggested, just backup a bit and you will get the same effect as changing your lens.
 
I think the fact that the handle and hand strap side come off is brilliant.

I think it will be about 2 months before someone comes up with a replacement side plate with a zoom toggle with a mechanism to drive the zoom or focus rings on some of the current and legacy lenses.

Im thinking like some sort of PTO port for lack of a better term.

Im also hoping that Panasonic doesn't cripple an upcoming GH2 to drive sales to the AF100. For me at least, I would like to have one of each as quite often I choose my current GH1 over my HMC150 not for any other reason but to be less obtrusive and more stealthy or because I need something small.

And did i hear someone say Uncompressed audio? I wonder if thats what the second SD card is for? Could you even record uncompressed audio in the AVCHD framework?
 
I must say : its not pretty....pretty boxy and with the pancake it must look ridicuous...but panny list it under the pro department while GH2 will be consumer 4 sure!
I wonder why they couldnt get the AF100 any smaller.....

What did they shoot that video on? The greenscreen work looks horrible. Due to low colour sampling, all of the edges in his white shirt just look atrocious at 720. It reminds me of the old 4:1:1 days, and if that happens to be 4:2:0... well, that's going to be a deal killer for me.
 
Yeah, that's a shabby looking key. Certainly doesn't look very AVC-I to me. I don't think you can pull a matte that ugly with an HPX370/300, let alone the VariCam they should have been shooting with.

I guess they're excited about pulling Scopier aspect ratios now that they've put 2.40 guides into the camera?

Question (Sorry if you have covered this). With the size of the sensor in the AF-100 what are the full range of lenses or should I say mount types (PL, Bayonet, etc.) that can be used on it.
Click to expand...
Just about anything. PL, Arri Bayonet, Aaton, Nikon, Canon, Leica, Minolta, Pentax K, Pentax Screwmount, Olympus, c-mount... those are just the adapters I can think of offhand. Oh, and B4 ENG lenses too.

But, some of those are going to vignette. Wide-angle c-mount lenses (wider than about 30mm) will vignette, as will B4 lenses.

I've read threads about the using machined Fujion and other really cool fast lenses on the GH1. Will these type of mods prove useful with the AF-100.
Click to expand...
Of course. Anything that can be mounted to a GH1, can be mounted on an AF100.

GH2 has nothing to do with the AF100. They're sold by different companies.

And did i hear someone say Uncompressed audio?
Click to expand...
Yes. LPCM uncompressed audio at 48KHz and 16-bit.

Could you even record uncompressed audio in the AVCHD framework?

The potential for uncompressed audio existed, yes, but all prior AVCCAM cameras have used only compressed audio.

I don't believe we know what camera was used to shoot that video. I doubt they used one of the prototype AF101 cams to shoot it. Why would they use a cam that's less than 70% complete to shoot a marketing piece?

You're certainly entitled to an opinion, but it may be OT to discuss the production values of a marketing video in this thread unless we know a AF101 was used to shoot it. Cheers.
