Voigtlander lenses

Alexauwa — Tue, 08 Nov 2011 18:42:54 +0000

When filming on the GH2 I`d like to shoot on Voigtlander lenses.

I'd be great to hear your feedback on it in term of sharpness, DOF, Bokeh and types.

I am primarily interest in the 25 mm 0.95 as it fits straight on the GH2 but als on
the Voigtländer Nokton Classic 35mm F1.4, 50 mm f1.1. and 50mm f1,5 which
require an adapter.

What experiences do did you make? What adapter do you recommand and whats
the difference using on?

Looking forward to your replies.

Best,
Alex

25mm F/0.95 Voigtlander - Shooting in the dark

Alexauwa — Mon, 19 Mar 2012 15:08:24 +0000

Hi everyone,

I am shooting on the Voigtlander 25 mm f0.95. I've tried several shots, insight and outsight. I've noticed that in some parts the dark areas were absolutely clear, no noise at all, but in some where were. I've keep ISO between 320 - 640, f0.95.

How do I get, even if there is less light, the most best possible result - here a clean picture? Do I have to raise ISO in order ta achieve better results? (Sensor need more light sensitvity to bring out details, can you shoot on too low ISO?) I always thought: lower IS0 value= better picture quality.

How do you handle night shoots, any tricks? Any help would be much appreciated!

Thanks, Alex

Icarus Patch - Just For HBR (current: 0.0.6 60mbps 25p stable, GOP6)

Athiril — Mon, 27 Feb 2012 05:12:17 +0000

LATEST: Icarus Alpha Test 0.0.6

Updated to GOP6 from GOP5, to fix stuttering.
up to 60mbps
2x trick mode in some scenes (Death chart)
QP16
Borrowed I, P, B frame scaling from Flowmotion
Improved Stability, so far have not been able to crash this in any test

Icarus 0.0.6 (indoor scene, f/2.8, 24mm, ISO3200, custom WB) (first couple seconds had rough motion, second half of bitrate distribution is what you normally see fairly static, where as movement scales up the B frames), typical B frames larger than Flowmotion's I frames.

Flowmotion 1.11 (same as above), much lower bitrate (imho it just cannot deliver with HBR modes), also crashes death charts with speed errors.

See what you think.

This is currently an Alpha Test. It needs more testing, but since I am pursuing the best HBR can offer, I've always found full daylight to be the bane of any attempt at raising HBR bitrate, I shall see how it performs in the morning in that regard.

GH2 MJPEG 1080p 25 fps.

Odd. Last time I tried the Change fps function for MJPEG it just fubar'ed all the time.

Now I went to stock settings (original GH2) for MJPEG with 25 fps, worked. So loaded the LPOWELL 100mbps/night 1080p settings, added 25 fps changed, works on my GH2. I'm not sure if it's merely dropping 5 frames out of every second (don't think it is). But if you shoot 1/25th, not sure if that it'd matter?

I'll try to examine it at some point with some linear motion at fixed speed, and look for 'jumps' in space.

My test file is reported as 75,697 kbps. Or 74 mbps. Which would be 88.7 mbps @ 30 fps, at the same average size/compression per frame. Available recording time is reported as 3m 12s. Recording on a Transcend 32gb class 10.

Test file was shot at ISO 2500, probably a stop underexposed still by the looks, just messing around in indoor light.

I'll do some slow panning on a monopod tomorrow with shutters @ and greater than 1/30th, and upload that.

Also I have gotten sizes a bit above 1080p working fine before too, which is useful I think for stabilising software if (such as deshaker) if you can shooter slightly wider than you want/need, so you don't have to blow up (or blow up as much) back to 1080p frame size for a 1080p output workflow. Combined with 25 fps would be great.
