Philip Bloom's first test

Yak said:
Skew is a similar problem to "jitter" created when a 35mm film camera is paned faster than the "recommended panning speed", now that we are getting video cameras that look like film we need to remember (or learn) proper "filming" technique. When you move a 35mm film camera too fast the end result can be quite disturbing, there is not one proper speed for panning that is why there are charts for "recommended panning speed" which depend on the cameras frame rate and lens focal length, for example for a 90 degree sweep of a static scene where the frame rate is 24 and the shutter angle is 180 with a 50mm lens then the pan should not be less than 23 sec. while with every thing staying the same but using a 35mm lens then the speed of the pan can increase to 18 sec. and with a 100mm lens it will take 1 min. Panning faster than the "recommended panning speed" will result in a pan full of jitter and quite disturbing to watch. Excessive movement with a CMOS camera creates a Skew or a jello look this can be overcome with proper camera technique, it is up to the camera operator to know the limits of his tools so that he/she can create the best image. Until someone makes a CMOS camera with a global shutter then we will have to put up with skew, even the RED has Skew. Since some cameras are better than others the question should be not if there is skew but how bad is it compared to other CMOS cameras.

holy god. 23 seconds to pan across a landscape? who in their right mind would ever pan that slow. sounds like something out of Barry Lyndon run in slow motion

Any cinematographer worth his/her salt, a 90 degree pan is 25% of a full circle and if you are using a 100mm lens it will take 1 minute ( with 180 degree shutter, 24FPS, on a 35mm film camera)
 
oh ok..i guess if you're using 100mm doesn't sound as slow. but imagine panning with a 20mm or less 90deg in 25 seconds.

that sounds somewhat reasonable.

so what if I yank a arri 535 across 90 degrees in 3 seconds. what happens does a interstellar wormhole open up?

No but it will look like crap, my point is we need to know the limits of our tools, CMOS cameras have motion limits as regard to skew or jello effect. I am looking forward to finding out the limit of the AF-100.
 
"Af-100 is a GREAT camera. Not a DSLR killer as touted by some, but really very good. Read my review this weekend with footage!! "

hopefully he means that in the way that it's nota killer due to price range... That you pay for what you get and those who cannot afford the AF100, the DSLR is still the best bang for the buck.

im hoping lol, again, we need to production version to really know for sure,,,.. I digress

The 5D is, by far, Philip Bloom's favorite HDSLR. The AF100 sensor is quite a bit smaller than that. The only true replacement for him would have to be a video camera that shoots FF35.

Also, there are benefits to the small size of the HDSLR bodies.

"Ok managed to get some nasty skewing with wider lens closer up to object. Better but not perfect"

That's a little worrysome.

With most CMOS sensors, panning right-to-left results in less skew than panning left-to-right.

For example, refer to the 3:38 point in this Panasonic "shooting tips" video:
http://www.vimeo.com/5348383

Not a biggie, but it'll be interesting to know which panning direction Philip used when he compared those two shots & lenses. We'll find out soon enough if he posts footage of these 2 shots. Cheers.
 
I'm not worried about sensitivity. I shoot narratives mostly and an used to writing with 35mm adapters. But I can understand his admiration for the 5d
 
Philip Bloom said the full review and all the footage will be posted this weekend.


one tidbit on his comments section of his blog also stated that the view finder for AF100 is "quite poor i'm afraid"
 
So then why do it? I'd really love to know. Everyone seemed to ignore or dismiss my previous comments, regarding this question.

Regardless....someone please tell me of a time when a PERFECT camera rolled out of a factory. People can nitpick all they want a camera...but at the end, I think these initial test drives are essentially important.

Rather than focus on the shortcomings of a prototype, why not focus on the possibilities?

well i would think that's only a 'problem' if the particular thing that he made a comment about is unfinished. i mean we know the cam is not yet fully finished but i was under the impression that most of the 'unfinished' bits were the sensor optimization and such. are you saying the viewfinder is also not in its finished state?

Either way who cares..I'll be first in line dec 27. But I do think you guys should have rethinked giving it to such canon lovers like Bloom because what else did you expect, I'm sure he'll conclude this weekend that his 5d is still better than af100, no big surprise for me there
 
Jan i would much rather you send a af100 ASAP to Mark aka plasmapm or whatever his name is on this forum. he's the other expert with a good following who is bipartisan and was a user of 7d/5d until gh1 hack during which time he was one of the first to run full blown resolution tests on his video series that proved gh1 is resolving far more resolution than 7d
