Alistairm Posted January 5, 2021 Share #1 Posted January 5, 2021 Advertisement (gone after registration) Has anyone had a crack at the SL2-S for astrophotography or other long exposures yet? While not a large part of my photography, I have enjoyed some astro landscapes on recent trips. Last trip I found the SL2's results to be pretty awful and ended up doing all my astro with the X1D. I'd love to hear/see feedback on how the SL2-S goes in this application. Quote Link to post Share on other sites More sharing options...
Advertisement Posted January 5, 2021 Posted January 5, 2021 Hi Alistairm, Take a look here SL2-S for astro. I'm sure you'll find what you were looking for!
FrozenInTime Posted January 5, 2021 Share #2 Posted January 5, 2021 @Alistairm Just tried it, but the sky was too bright even before moon rise. This time next week brings a new moon, so weather permitting will try again. 1 Quote Link to post Share on other sites More sharing options...
eab Posted January 6, 2021 Share #3 Posted January 6, 2021 I am not that familiar with the SL2, can you explain what the issues are regarding astrophotography? I am trying to decide between the two models. Quote Link to post Share on other sites More sharing options...
Cattoo Posted January 6, 2021 Share #4 Posted January 6, 2021 The SL2-S should be better for astro work. You get better performance at higher ISOs and you'll see less noise and fewer star tails with the lower (but still respectable) 24mp resolution. In theory anyway. I have an SL2 and it's not so good for astro. I was about to buy a Sony A7III but then Leica released the SL2-S. I'm leaning toward that now but would like to see some examples. Most of the examples I've seen, though, have long-exposure noise reduction enabled, which you do not want for astro work since it tends to treat some stars as noise and effectively erase them.

Can you elaborate on how stars which are present in the actual exposure gets removed by taking a black frame without the shutter open? This is news to me.

Cattoo Posted January 6, 2021 Share #6 Posted January 6, 2021 6 hours ago, beewee said: This is news to me. simply google “noise reduction” and “Astro photography” for a dozen articles on the topic. Yes, you can use noise reduction, but some stars in your photo will be faint, tiny points of light that will inevitably get lost /erased when NR is applied. (see link below for more info on the topic) This has long been the bane of Sony users (google sony and “star eater”) until the A7iii, which allowed you to disable the feature. People still complain that they lose stars though. Perhaps Leica’s NR doesn’t eat stars the way other cameras’ NR does. I don’t know, I’ve been trolling the forums for examples but no one has posted a long exposure Astro photo just yet. It’s not the best time of year for Milky Way photos in the northern hemisphere. https://www.lightstalking.com/noise-reduction-on-off-astrophotography/amp/ 1 Quote Link to post Share on other sites More sharing options...

Yes, the Sigma 14mm f1.8 Art is great - but one should test the lens prior to serious use (seems to be some variations). The SL 16-35 is not a good lens for astro - too much distortion/aberrations towards the edges/corners. But SL24-90 @24mm is outstanding! (albeit a little slow).

Paolou Pigini Posted January 7, 2021 Share #11 Posted January 7, 2021 (edited) Don't know if Leica applies any Noise Reduction on the raw, but the sensor is practically identical to the one of the S1, so the best one, in the 24x36 range, in this regard. Low read-noise, low long-exposure noise (https://www.brendandaveyphotography.com/more/long-exposure-sensor-testing/), details. Regarding the noise from long exposures, depending on how the electrical circuits are built and how the heat is dissipated, the performance may vary, but the sensor itself works very well. 14-24 DG DN is the perfect lens for astro-landscapes.

I don't remember the exact values, but I reckon about 4 minutes of exposure for the tracked starry sky (Ioptron Sky Tracker Pro) at f/2.8, and same time and f/4 for the rocks. Lens is really sharp already wide open, well controlled coma and no issues at all...moreover is versatile in focal lenghts and lightweight. I have this early-summer raw test (similar exif), there was a little more light pollution than the photo above but it's better than a thousand words to evaluate the sensor and lens, it being understood that we have to see how they implemented the SL2-S: https://drive.google.com/file/d/1wVbOk0xSTJUjsGaMiXfYhI7hqj3Pi3iH/view?usp=sharing Edited January 8, 2021 by Paolou Pigini 1 Quote Link to post Share on other sites More sharing options...

KateStarr Posted May 10, 2021 Share #17 Posted May 10, 2021 I just wanted to give this a bump to see if anyone has used the SL2-S for astrophotography at this point. I figured there might be some folks who have gotten out to shoot the Milky Way with it at this point. Cheers. Quote Link to post Share on other sites More sharing options...
bcorton Posted June 20, 2021 Share #18 Posted June 20, 2021 Another bump. I’m interested to see if the new back-lit sensor delivers substantial gains for astrophotography. Anyone? Quote Link to post Share on other sites More sharing options...

Anyone? I've just purchased an SL2-S as a back up for my SL2. I received the camera yesterday and will be trying out some astro shots with the Sigma 14-24mm L in the next few days. Will hopefully post some images later this week. 4 1 Quote Link to post Share on other sites More sharing options...
