masquar Posted November 18, 2015 Share #1 Posted November 18, 2015 Advertisement (gone after registration) Hi everybody, I must admit that I didn't go through all the manual but from what I saw, when zooming in on a DNG shot its resolution is really poor compared with the one of the jpg shot, as a well as the DNG+jpg one. It looks like an out of focus shot. When I discovered this I thought there was a problem with autofocus. But after uploading the shots in the mac they looked absolutely perfect. Does anybody know why this happens? Am I doing anything wrong? Thank for your answer. Massimo Link to post Share on other sites More sharing options...

mjh Posted November 18, 2015 Share #2 Posted November 18, 2015 There is only a low-resolution JPEG preview embedded within the DNG file. DNG+JPEG mode takes care of that. Link to post Share on other sites More sharing options...
masquar Posted November 18, 2015 Author Share #3 Posted November 18, 2015 Thanks Michael. I thought that too. I will choose DNG+jpg then. Link to post Share on other sites More sharing options...
Ario Arioldi Posted November 18, 2015 Share #4 Posted November 18, 2015 The embedded jpeg is unusable for focus checking and you are forced to save DNG +JPEG and then discard the JPEG if you do not need it. I do not need JPEG's and I find this a bit disappointing. Link to post Share on other sites More sharing options...
BerndReini Posted November 18, 2015 Share #5 Posted November 18, 2015 Don't be disappointed. If Leica included a high resolution preview JPEG in the DNG file, you would loose the advantage of the smaller file sizes when shooting JPEG only and you might as well shoot DNG+JPEG. The small embedded preview JPEG looks soft because of the high resolution EVF compared to the M9 or even M240. Have you ever noticed how small JPEGs that looks fine on older laptops all of a sudden look soft on the Retina displays? If you want to use a zoomed in view on a high resolution display, you need a big file. Link to post Share on other sites More sharing options...

I understand your point, but I never use JPEG and this is the only camera I have with an almost unusable embedded JPEG ( I have other Leica's, Nikon, Sony, Fuji...)

scott kirkpatrick Posted November 18, 2015 Share #7 Posted November 18, 2015 Advertisement (gone after registration) I see this as a plausible tradeoff. My Ricoh GR also needs to have me shoot RAW + JPEG if I want to have a decent review image in camera. So I will probably shoot DNG + JPEG in the SL, buy bigger cards, and nag Leica to allow "split saving" so that the jpegs go onto card #2 while the DNGs which I save go on card #1. Cards are cheap, and the SL writes them quickly. scott Link to post Share on other sites More sharing options...
thighslapper Posted November 18, 2015 Share #8 Posted November 18, 2015 Leica have adopted this with all the recent cameras ....... T, XV, Q and now SL All use the jpg for review. On the T this is obvious when you use the lower jpg resolution settings. I don't think Leica will change this as it appears to be a deliberate decision and part of their uniformity of file handling with the firmware ..... which if they had any sense they would make as common to all platforms as possible .... saves time consuming and costly re-writes Link to post Share on other sites More sharing options...

edwardkaraa Posted November 18, 2015 Share #10 Posted November 18, 2015 I like how it works with the M240. I'm not sure why we're back to the M9 days. Link to post Share on other sites More sharing options...
Guest JonathanP Posted November 18, 2015 Share #11 Posted November 18, 2015 It does seem odd, given that the M240 is often criticised on here by people complaining that it has an underpowered processor, yet does provide a nice zooming preview with DNG only. I wonder if this is one of the compromises needed to support a higher FPS on the SL? Link to post Share on other sites More sharing options...
scott kirkpatrick Posted November 18, 2015 Share #12 Posted November 18, 2015 I wonder if this is one of the compromises needed to support a higher FPS on the SL? I don't think so, since the fps guarantee is stated to work for DNG + JPG. I think it is a side effect of having a 4 MPx viewfinder with which to review in camera. I don't know how big the embedded jpeg in the M240's raw files is, but I do notice that enlarging more than 8 or 10x doesn't produce more meaningful information when checked on its LCD screen, which has about 1 MPx resolution. scott Link to post Share on other sites More sharing options...
masquar Posted November 18, 2015 Author Share #13 Posted November 18, 2015 I like how it works with the M240. I'm not sure why we're back to the M9 days. Well, with the M240 and the M9 as well it was possible to have a good DNG preview in camera but zooming in was damn slow. I don't know the reason why Leica has changed the reviewing method and having a jpg close to the DNG might be useful (black and white jpg, for instance). What I see is that with the SL the reviewing speed of the image, whatever it is, has been increased a lot. I think it is worthy to be noticed that now you can shoot with the preview off and there is no frozen image that delay the next shot. This is very important to me, so far.

jonoslack Posted November 18, 2015 Share #14 Posted November 18, 2015 I guess they have their reasons To be honest, it's not so much of a chore to delete the jpg files afterwards, and the zooming capabilities really are very good. Link to post Share on other sites More sharing options...
IkarusJohn Posted November 18, 2015 Share #15 Posted November 18, 2015 I seem to recall that you can tell LightRoom not to download the Jpeg files, and they get ditched with the card formatting. With the M9, I followed Thorsten's advice to set the Jpeg to B&W so you got a B&W image on the LCD. Even the Monochrom has a small embedded Jpeg for the LCD while the DNG loaded. I don't really see this as a huge chore. File storage is cheap, and generating a Jpeg for those times you do want to check the LCD is not really an issue.

helged Posted November 19, 2015 Share #16 Posted November 19, 2015 I seem to recall that you can tell LightRoom not to download the Jpeg files, and they get ditched with the card formatting. Correct, if you shoot DNG+JPG but will only load DNG into Lightroom, you deactivate "Treat JPEG files next to raw files as separate photos" in Lightroom/Preferences/General.

Flu Posted November 21, 2015 Share #17 Posted November 21, 2015 Thank you for this thread! I was scratching my head wondering what was going on!? The SL is the first camera I've ever owned that requires this type of configuration. Seems a bit odd to me. Link to post Share on other sites More sharing options...
scott kirkpatrick Posted November 21, 2015 Share #18 Posted November 21, 2015 It's not such a rare practice. Other makes, and other Leica models do this. It keeps the raw file size down. And the new viewfinder needs a lot of pixels to do magnification checks on the finished image. scott Link to post Share on other sites More sharing options...
