The arguable real (dis)advantage of anamorphic shooting with adapters.

Ze_Cahue — Tue, 09 Aug 2011 16:00:37 +0000

I didnt find this related topic, just a few floating opinions inside other anamorphic topics.

Let me start point it out.

What is the real advantage of putting a glass above another glass to change the pixel aspect ratio, and get arguable more horizontal resolution?

If we use a real and good anamorphic lens, we get a real advantage in terms of resolution. But just put an adapter over a lens is not always a good idea. Resolution is not only pixel quantity, but pixel quality. If we need to use extra glass to get these "extra" wide, we will be loosing resolution by the degradation of quality caused by the extra glass. Experiment put many filters in your lens, than pixel-peep it. You will notice an image blur. This is what happened with most (I say most, not all) adapters around. It is fancy to shoot anamorphic, but what is the real advantage? Lets go to an example:

If you use a 7-14mm lens at 7mm than just crop to get the desired ratio. You get an anamorphic ratio and very wide frame. You cannot use an anamorphic adapter in very wide lenses. So, you win in one side but lost in other.

What you get:
* more horizontal resolution
* some flares (arguable positive)

What you lost:
* very wide lenses
* the capability of use fast lenses at wider apertures
* time
* money

Some guys claim that can achieve 2k resolution from full HD by using anamorphic adapters. This can be untrue depending on the configuration used.
The extra horizontal resolution gained from the pixel squeezing can be lost by the image degradation caused by extra glass, not not mention here vignetting.

Anamorphic fan guys, please no offence here, lets try to use logical arguments instead of emotional ones.

Just found this interesting DIY monitor kits at aliexpress.com $217.55 There is also 5.9 inch models with 1440*2560 resolution. Wonder if it accepts 1080p signal from Panasonic GH and Blackmagic cameras. Have no idea how to control brightness, color temp and other settings :)

"Black Betty": Custom built RAW camera using SI-2K Mini & Mac Mini

CRFilms — Thu, 29 Aug 2013 02:23:32 +0000

This artice of a custom camera that was made using a SI-2K Mini and a Mac Mini in a custom housing to resemble a film camera.

http://blackbettycameras.com/first-camera/

Interesting cam. Since some old Mac Mini's use 12v unregulated power, you can rig them up to a battery. It shoots cineform raw. It reminded me of this old topic. http://www.personal-view.com/talks/discussion/3725/4k-usb-3.0-camera-with-raw-option-less-than-1k/p1

The Flea3 costs $900(you need to register to see prices) and can do 4k at 21fps and lower res at 24fps, but not sure what res. Another cam with max res of 2k and 60fps costs $650.

AVCHD VS MJPEG

Manoosh — Thu, 22 Aug 2013 12:45:42 +0000

Hi everybody.

Thanks to every workers and tester for your job.

I see lot of post about Mjpeg vs avchd, the majority of people say avchd better than Mjpeg. But today I'm not sure...

I was making a shot test between 24h/HBR/Mjpeg with "Driftwood Cluster X series 3:│moon T7" The scene is very contrasted with highlights and black.

I prefer Mjpeg...!!! Because the noise is the same and I see more details and more sharpen.

I want know if somebody testing Mjpeg and say the same thing.

25p and 2K possible? with the option Mpjeg fps of ptools?

The time limite?

Mjpeg in 2K 25p no limited time, It 's dream for me.

Thanks for your answers!

With the help of the tutorial of eyepatchproductions, here is a clip at 2K that i've posted on Youtube. I am impress by the quality of the Samyang lens.

I just received my Red 17-50mm Prime lens i am now waiting for the adapter to fully test it on the GH2

Just watch this video on vimeo & the guy claims with his hack GH2 can record MPEG2 4:2:2 @ 2K (2048x1152) let me know what you guy's think about it, or if it's fact or fiction..
