thighslapper Posted December 27, 2015 Share #1 Posted December 27, 2015 Advertisement (gone after registration) As I have had the cable release for some time I decided to have a play during the festive lull..... .... and yes, you can take exposures of any length over the 60 second limit with the release locked. I had the forlorn hope that the subsequent NR exposure would max out at 60 seconds ..... but no, it keeps going, going, going to the bitter end ...... Somehow I can't see me taking long exposures and waiting the same period again for NR ........ on a happier note...... Doing some tests on the OIS performance and rather gratified that I can handhold at 90mm down to 1/15 sec with no obvious detriment to the image quality ...... at 1/10th sec some slight blurring of edges at 100% creeps in. As image quality doesn't suffer much till 1600 and above that gives a fairly potent combination in terms of low light performance which way offsets the modest apertures of the 24-90..... I'm impressed Link to post Share on other sites More sharing options...

I'm impressed Exposure length is limited to 30 minutes in Bulb mode. This will cover most everything except for star trails with a wide lens (1-2 hours is ideal for that application). Leica really needs to make the long exposure noise reduction a menu item and leave it up to the user. Lightroom catches the hot pixels and does a great job of fixing them. And of course, we can do dark frame subtraction manually, with one frame at the end of the shoot if desired. Here is a shot with the 50 Lux ASPH at F4, 30 minutes, ISO 100 Welcome, dear visitor!
