halayli Posted January 1, 2015 Share #1 Posted January 1, 2015 Advertisement (gone after registration) Hi, I don't know if anyone else has experienced this but intermittently, I have issues taking successive shots in single-shot mode. I take a pic, wait 1/2 a sec or more and try to take another pic and nothing happens. I have to release the button and press again. It doesn't happen in continuous mode or at least I haven't experienced it in the few times I used it. I am wondering if it's a memory card(SanDisk Extreme PRO 64GB UHS-1/U3 SDXC) issue or a camera issue or if it's an issue at all. Is the camera buffer used in single-shot?

algrove Posted January 1, 2015 Share #2 Posted January 1, 2015 You did not say if you are using the LV or not. If so, lag is normal in this case when using LV. Many of us use the Sandisk 64/95mb/s. It is the mb/s that is important so I guess even you omiitted that piece of data that is the card you are using. Link to post Share on other sites More sharing options...
lct Posted January 1, 2015 Share #3 Posted January 1, 2015 I would save the content of the card, format the latter with SD Formatter and see what happens. Link to post Share on other sites More sharing options...
250swb Posted January 1, 2015 Share #4 Posted January 1, 2015 If in Live View you will get a lag, it requires the shutter to close, then open, then close, then open again. Steve Link to post Share on other sites More sharing options...
jaapv Posted January 1, 2015 Share #5 Posted January 1, 2015 And yes, it is possible to fill the buffer in single shot mode. If you do you will have to wait for it to flush one shot at least to be able to take another. Link to post Share on other sites More sharing options...
halayli Posted January 1, 2015 Author Share #6 Posted January 1, 2015 Yes I am using the 95mb/s card. No LV. I ran some tests now, and it seems it only happens in lower light conditions. In low light conditions, If I take a pic and try to go for another one too fast for the camera nothing happens until I release and press again.

In low light conditions, If I take a pic and try to go for another one too fast for the camera nothing happens until I release and press again. How low is low light, i.e. what exposure times are we discussing? IIRC, from one second onwards, the camera spends a fair amount of time to reduce the noise in the shot.

IIRC, from one second onwards, the camera spends a fair amount of time to reduce the noise in the shot. Aperture priority, shutter speed where the issue happens is 1/15 and below. The slower the worse of course. Maybe it's noise reduction but just not showing it on the screen since it's less than 1 sec? One thing I noticed now is that in continuous mode at this speed there's also a lag between the consecutive shots taken. Meaning it's waiting on something(probably noise reduction) before it can take the second shot. Probably I am just impatient and there's no issue.

DTM Posted January 1, 2015 Share #9 Posted January 1, 2015 Are you shooting DNG and Jpg or just DNG? It may be creating the Jpg file that takes the extra time? Just a thought. Link to post Share on other sites More sharing options...
halayli Posted January 2, 2015 Author Share #10 Posted January 2, 2015 Are you shooting DNG and Jpg or just DNG? It may be creating the Jpg file that takes the extra time? Just a thought. Nope, just DNG. I also tried with compression off. Basically once I shutter speed is 1/15 and below I notice a lag. If I set it on continuous with a shutter speed of 1/15 <=, it takes ~1 pic a sec and sometimes less at slower shutter speeds. I also removed the SD card and still noticed the same behavior. How many pics can you take with similar settings? Does it take the same # of pics at let's say 1/30 ? Link to post Share on other sites More sharing options...
LD_50 Posted January 2, 2015 Share #11 Posted January 2, 2015 I have not experienced any similar lag with my M-P. I would suspect the SD card and try another if possible. Link to post Share on other sites More sharing options...
halayli Posted January 2, 2015 Author Share #12 Posted January 2, 2015 And just to clarify, when I said "lag" I wasn't referring to "shutter lag", by lag I meant it doesn't let me take another pic until after 500-700 milliseconds or so have passed.

algrove Posted January 2, 2015 Share #13 Posted January 2, 2015 What ISO in "low light" are you using? What lens and f stop? I will try to duplicate it on my M-P if I have all the particulars. By 1/15 and below-do you mean ⅛, ¼ etc. by the word "below"? Link to post Share on other sites More sharing options...
halayli Posted January 2, 2015 Author Share #14 Posted January 2, 2015 What ISO in "low light" are you using? What lens and f stop? I will try to duplicate it on my M-P if I have all the particulars. By 1/15 and below-do you mean ⅛, ¼ etc. by the word "below"? I have it set to ISO 800. By lower I mean't slower yes, 1/8, 1/4. Obviously at lower shutter speeds you'll take less pictures, but going by what I am hearing I feel there's additional processing going after the picture is taken. P.S this is my first Leica and I might be dragging you to a wrong path. I just don't have another Leica to compare it with and this is just a normal behavior.

halayli Posted January 2, 2015 Author Share #15 Posted January 2, 2015 but going by what I am hearing I feel there's additional processing going after the picture is taken. After I hear the shutter released, I can press 3 times quickly and no picture is taken. This doesn't happen at 1/30 for example, no matter how quickly I try to take another picture, it always succeed. Link to post Share on other sites More sharing options...
LD_50 Posted January 2, 2015 Share #16 Posted January 2, 2015 I just tested ISO 800, 1/15, 1/8, 1/4, 1/2 and could not duplicate an inability to take another shot unless I hadn't waited for the shutter itself. This was most noticeable at 1/2. Link to post Share on other sites More sharing options...

LD_50 Posted January 2, 2015 Share #19 Posted January 2, 2015 I am able to take a photo right after the shutter releases, though I may have seen a slight delay at 1/2" a few times on the third or fourth shot. I can't see why I would ever shoot this way at slow shutter speeds without stabilization so I don't think this is something I would have ever encountered.
