Video with Voigtlander Heliar 75mm f1.8 Classic on a Panasonic Lumix GH1.
Mostly shot at f1.8. There's a fair bit of CA and purple highlight fringing on some of the sections with a bright sky behind. Obviously with the outdoor location, there was no real need to use f/1.8 but I wanted to see how the lens looked wide open.
This was the first opportunity I had to see what difference the Tester13 GH1 hack has made. It has resulted in a cleaner output. Previously some shots I'd taken with running water were full of compression artefacts and these are better. It will be interesting to run a comparison between this and the GH2.
I'm going to put together a low light video using both this lens and the other fast lenses I now have. I now have available:-
Lumix 20mm f/1.7 pancake. (40mm 35mm / Full-frame equivalent)
Voigtlander 25mm f/0.95 (50mm 35mm / Full-frame equivalent)
Voigtlander 35mm f/1.4 (70mm 35mm / Full-frame equivalent)
Olympus 50mm f/2 (100mm 35mm / Full-frame equivalent)
Voigtlander 75mm f/1.8 (150mm 35mm / Full-frame equivalent)
The obvious gap in all of this is a fast wide-angle. At the moment I can't see where this might come from. The Panasonic 14mm f/2.5 is the fastest option at the moment. Whether or not its possible to produce something like a 10mm f/1.8 or a 12mm f/2 I can't say. There may be something to come from Voigtlander in the future, but at the moment there are fairly limited options. I'm not at all interested in c-mount lenses and both the Panasonic and Olympus zooms, while being good quality have slow maximum apertures.
Wide-angles are currently the least well served area of m4/3 and there's not really any options available on the legacy lens front, due to the 2X crop of the sensor.
