    Re: The problem with the new Nikon and Canon

    Reading all the thoughts about the one vs. two card slots has revealed something surprising. Namely that SD cards are fragile, or so says many posters.

    They seem tough enough to me.

    They do fail a lot, everyone I ever talked with who shoots a lot and does file transfer from a card reader has had card failure, either mechanical where the case separates and the locking tab breaks or a data loss problem with either contact or the memory die itself fails. CF cards fail with bend pins and occasionally pins get stuck in the socket so inserting a new CF ruins that one also. They work well in set and forget applications where only pulled out rarely, by doing cable transfers. That latter option is slow. It was a bad enough problem that the manufacturers pooled resources and designed a pro-rated system that overcame the frequent problems with SD and the well-known CF pin alignment problem that could cause an expensive body repair. The XQD has resolved the problem, although it is more expensive.

    If SD cards are as unreliable as some are claiming, then the lack of a second SD slot in the D7500 is a double whammy. Gee, I don't know how I survived for 10 years with my D200?

    Re: The problem with the new Nikon and Canon

    If I hadn't experienced a problem with damaged images, I might not be so insistent on having 2 card slots. But on a couple of occasions, I've had images that had either pink or green fringe along one edge of the frames. I'm reasonably sure it happened with Lexar cards which is why I stick with SanDisk now.

    And one time I experienced an issue with an image that took forever to write to the card. Not sure how or why it happened or if both slots experienced the issue, but eventually the light on the back of the camera turned off. It wasn't until the light went off that I was able to actuate the shutter again. I didn't lose any images from this, but at least I had a second slot in use as a precaution.

    To each his/her own.

    That slow writing to the card is not uncommon and primarily due to unprotected contacts that can partially work but only with many retries so the camera does not trigger a fault routine, as "it thinks" the card is good but high resistance contacts fail to transfer the data correctly so it retries and keeps retrying. I use a little bit of deoxidation treatment periodically on my SD cards used in the D700 and the backcard in the D800. I have had 4 sessions hurt by card failings but always had another camera.
    My biggest contact problem with oxidation or wear is my grip to body multi-pin connector. After so much use, daily it might be time to retire the Chinese grip that has served so well since the D800 came out. About the best $75 I invested in accessories.
    While the second slot missing would not be a concern there are two issues with the Z7 that would not be welcome, no grip duplication of controls for vertical holding. No shutter release, no second AF-On button and fastest flash sync is 1/200. That was probably lowered from 250 because the Z7 has a ISO setting of 35 so you can get by without a ND filter to get down to 1/200 in a bright scene or when trying to create a low key shot in a normal room ambiance level. The low ISO extended range is actually more useful than the normal Nikon 1/200 1/320 sync speed.

    I guess I balance you out, Cindy, because the two SD cards I have had fail are Sandisk, and I've yet to have a Lexar fail.

    As far as the discussions of SD cards vs XQD, all you have to do is hold an XQD card in your hand to know it is built in a much more sturdy manner, and with no exposed contact pins.

    Every digital camera I've owned had 1 memory card until I got the D750, on that the 2nd card is overflow. My other cameras are set up the same way. I guess I've been lucky so far because I'm still using the same cards that were put in the cameras when I bought them.

    But, but, but...my Nikon bodies don't use XQD. Then maybe Nikon needs to switch to one XQD card for their D7500 rather than one SD card. Just kidding...most people wouldn't want to incur the cost of those cards.

    I've been spooked enough (never too old to learn) to switch my D750 2nd card to backup rather than split jpg/nef's.

    Yeah, the cards are expensive. And even the UHS-II SD cards are pretty darned expensive, as well. I see that Delkin just came out with XQD cards, but they are only $9 cheaper for a 64GB than the Sony.
