trond Posted January 5, 2016 Share #41 Posted January 5, 2016 Advertisement (gone after registration) Yes, it seems so. Of my now eight Lexar 64GB 1000X cards, the four Rev D cards are ok like Wilson's. The Rev C cards will live their life in my Nikon D810. By the way, the startup time on these "slow" cards are 0.05 seconds in the D810, so go figure if anyone can! Best regards Trond Link to post Share on other sites More sharing options...

scott kirkpatrick Posted January 5, 2016 Share #42 Posted January 5, 2016 Dear Wilson, There are more parameters in this mess, than just the card brand and spec. I got hold of four additional Lexar 64GB 1000X cards, and these are just fine with regards to the startup time. The cards have a different design on the label, Black/Golden on the ones that don´t work, and Black/Silver on the ones that do work. The spec is SDXC UHS-II on all eight cards, four works and four of them don´t. Looking at the laser marking on the back of the card, the revision seems to be different. Slow startup time cards are marked: 31532-C10-64GBBM C Functional cards are marked: 31532-C10-64GBBM D I take the last letter C and D to be a revision code, and Rev D cards are ok in the SL, but Rev C cards show slow startup time. Please check your own cards an tell us what the laser marking on the back of the card says. Best regards Trond I've gone through 1.5 32 GB SanDisk Xtreme's, and didn't notice slow start-up. I also got two Lexar 64 GB 1000x cards in a single order from Amazon. One is a C and one is a D. With the C in the #2 slot, no pictures stored there so far, it takes an extra 1 sec to start up. If I remove the chip from #2, startup is one second faster. But with both it is still 3-4 sec. I'll be interested to see what happens when I move the C chip with some pictures into the #1 slot. BTW, how do you measure short startup times accurately? Are you videoing the process? scott Link to post Share on other sites More sharing options...
trond Posted January 5, 2016 Share #43 Posted January 5, 2016 Dear Scott, Put the Rev C card in slot 1, then power up, take a few pictures, turn the camera on/off a few times an see what happens. The short 50ms startup is an estimate. I work with HID devices (human interface devises, like mouse keyboard and remote control). Gamers require less than 10ms response time, or they will throw the damn thing into the wall, "normal" typing on a keyboard will feal sluggish when response time approaches 30-50 ms. The D810 is ready quicker than you can move your index finger from the on/off switch to the release button. The on/off switch is placed around the release button, like on the Leica M 240. I take it that it is safe to say the startup time is then less than 50ms with a sufficient safety margin. Best regards Trond Link to post Share on other sites More sharing options...
scott kirkpatrick Posted January 5, 2016 Share #44 Posted January 5, 2016 I put the C card in slot 1, nothing in slot 2, and it took about 8 sec to come up ("searching", then "searching" again, then "ready", then showing the state of the camera). It takes pictures just fine, but still is slower starting up. The D chip is in slot 2 now, waiting for its chance to shine. Maybe there will be a firmware fix before I need the C chip. thanks for the diagnosis, scott Link to post Share on other sites More sharing options...

scott kirkpatrick Posted January 6, 2016 Share #46 Posted January 6, 2016 One banana...two banana.... I'll keep that in mind when reading threads on startup time. Timing continuous shooting is more precise -- you just shoot an onscreen stop watch. scott Link to post Share on other sites More sharing options...

LocalHero1953 Posted January 6, 2016 Share #49 Posted January 6, 2016 My Lexars are the D version as well - takes a bit over 2 secs to start up, though I haven't measured it exactly. Given the performance of the Nikon, I think this is an area where Leica should up its game. Although, TBH, rapid startup/wakeup is less critical for me on the SL (I don't use it for street or casual shooting), it is on the M, where the performance is similar. I suspect that Leica is allowing a whole series of checks to be carried out (particularly on the card) before permitting shooting - checks that could wait until a later moment.

scott kirkpatrick Posted January 6, 2016 Share #50 Posted January 6, 2016 As you do when timing startup So you flip the switch when the onscreen clock passes 0 sec, and hold the shutter button down until it takes a picture of the onscreen clock? I was defining "startup complete" by the appearance of the final information in the top LCD. I'm not sure if that is the same time as first shot or a bit later. In practice, it might be best to leave the camera on, half press as you raise the camera and shoot when you see what you want to see. Power conservation in both standby and timed-off modes seem to be pretty good. scott Link to post Share on other sites More sharing options...

I agree with that Wilson! The camera should/could fire directly into the internal 2GB RAM buffer and then transfer the image to the card somewhat later when the card has been checked. If there is no card, or a faulty card, you lose the image of course. But then again, if the camera is not ready because it is checking the card, you loose the image anyway.
