| p.1 #8 · Lexar 1000x and 7D,5D2 and 5D3 action (hint matters a lot for one and not for the rest) |
7D 2.0 update:
Even with a Sandisk Extreme Pro 90MB/s 32GB card it appears to be zero difference compared to 1.2.5.
HOWEVER, pop in a Lexar 1000x 32GB card and with 2.0 it DOES come to life. With 1.2.5 that Lexar card made no difference, now it does.
Test 3 (on a 7D 1.2.5, shoot at a bright light or up at bright sky so the fps stay maxed, sadly can't use the same, repeatable body cap on as with all the other bodies since that makes 7D fps go to a crawl):
23 (29??) shots (up to 3.7s??) with a SanDisk Extreme Pro 90MB/s card
23 (28??) shots (up to 3.5s??) with a Lexar 32GB 1000x card
(not sure, when I first did the test I got the large 28-29 shot buffer, now I just can't replicate it, maybe something about the scene that time made it store the min level of data per frame while still keeping fps at max or maybe it was dark enough that time to not slow the fps fully but just a touch and I hadn't realized? anyway, I'd go with the 23 number)
(so the extra $ for the Lexar 1000x makes no difference on a 7D, same result)
Test 3b (as 7D above with now with 2.0 firmware):
getting about 27-30ish instead of closer to 23 for the current bright scene being shot (5D3 gets about 27 in this scenario) so the 7D now does about the same to a bit more frames than the 5D3 although at 8fps the total continuous shooting time is LESS than for the 5D3
and then trying it with a Sandisk 90MB/s extremepro instead 7D 2.0 gets:
(so with 2.0 firmware the Lexar 1000x now DOES make a HUGE difference for the 7D even if not quite as insanely huge as with the 5D3 since you get in this test about 23ish vs about 29ish and it doesn't slow as much once it slows either and refreshes more quickly too; also appears to show that you'd need one of the best of the best, the Lexar 1000x cards to take any advantage of the 2.0 buffer)
