Pentax Monochrome

HD DA 2.8/35

Been doing a very loose comparison between the Pentax and the M11M at iso 100,000 - not the one above - and agree with Frralscene that there is banding and pattern noise in the M11M files that is much less of a problem in the Pentax files - albeit I think the Pentax files are slightly noisier, they’re just overall better at that iso when opened up. At iso 12,800 I’d say it goes the other way, but maybe depends how hard you push them. Whatever, it’s a world away from pushing HP5+ to 1600 or 3200🙂

If you have some noise reduction programs, Topaz or the tools in LR or PS, try them. The main things that bother me about the Leica banding is that obviously it is there, but also if you try to reduce the noise (and note that there is a photo in my Rajasthan thread taken at ISO100,000 with the M11M that looks very good with no noise reduction, and which showed almost no banding) the noise reduction programs make it worse. This is the algorithms picking it up as broad-frequency structure and assuming it is part of the photo. Which it is. Just not how the programs think it is. Anyway, in ISO100,000 territory it comes down more to it being very hard to focus the Pentax with focus screen (hopeless), indicators (grey), extremely hard or lcd screen (white focus peaking or noisy image rendering) very very hard. It’s a paradox that the files are amazing, but the Pentax just isn’t very well set up as either a low light camera, or, for that fact, a monochrome camera generally.

To be honest, I don't really use noise reduction much, as I generally prefer the original file with whatever noise is there. And completely agree about the Pentax in low light - the Leica is much easier to focus. Unfortunately, the Leica doesn't even only show banding in really dark areas where you might not see it either. In reality, I'm pretty happy at 12,800 most of the time and both can happily have an extra stop dialed in in post at that level.
