I'm not too technical and wondered which cards were best for the A77ii spec says

Memory Card Slot : Dual compatibility slot: SD, SDHC, SDXC memory card and Memory Stick PRO Duo™/Pro-HG Duo™/PRO-HG HX Duo™ media

Any help appreciated

I myself am trying to glean as much info possible for my purchase of the a77M2 before this year ends. I save information that I find.

On SD cards here is some info I've come across from multiple sources. See this thread for a discussion on cards. http://www.dpreview.com/forums/thread/3674430

From other sources:-
"Skip the 64GB cards, those have to be formatted Ex-FAT and that can cause problems on certain devices."

Sorry I can't remember the thread for the following:--

"32GB 95MB/s is my recommendation to take advantage of A77 FR and Buffer.
90MB/s read and 45MB/s write

This particular memory card is one I highly recommend, I have the 16GB version. But I might also recommend looking at the new SDHC UHS-I U3 cards too. The one above is a U1.

What this means is that a U1 card guarantees a minimum write speed of 10MB/s. A U3 card guarantees a minimum write speed of 30MB/s.

While the numbers usually advertised are the cards peak speeds, they don't always reach that. So I might consider a SDHC UHS-I card that might have a slower peak speed (by about 5-10MB/s) but a higher minimum write speed by three fold. I know Transcend and Kingston both currently offer these type of cards and are relatively cheap. I have heard some mixed reviews about Transcend as a brand but Kingston has been pretty solid.

I plan on ordering today or tomorrow one of the new UHS-I U3 cards for my A77II and I'll compare the difference to see if it is notable or not between it and the Sandisk that has the higher peak speeds. ****


UPDATE **** I went ahead and ordered the Kingston 16GB UHS-1 SDHC U3 Memory Card. It is one of the few U3 cards with a minimum write speed of 30MB/s. It's peak read and write speeds are 90MB/s and 80MB/s, respectively. That puts its peak read and write speeds around 5MB/s and 10MB/s slower than my Sandisk but a minimum write speed that is 20MB/s faster.

We'll see how well it performs, both in camera as well as in reading off the pictures to the PC. If it performs better than my Sandisk, then I may order a 32GB one down the road as my second card. I will then move my Sandisk 16GB card over to my RX100. But as it stands, 16GB holds quite a bit since I shoot RAW only. If I recall correctly, I get over 600 RAW pictures on a single 16GB card (less if I record movies), which is usually enough for me on most single day shoots."
 
I bought this:


Seems to work great, Ive have ::knocks on wood:: Great luck with PNY in the past, it seems to have a good write speed I keep shooting and it keeps going, there is a slight delay in looking at the pictures when I keep my finger on the shutter but I can wait a few seconds especially because my instinct is to just shoot more when I am shooting that fast. and for the price I cant really complain though to be fair its probably just as good as my class ten PNY car or any of my other class tens. I guess it depends on how patient you want to be, as I said in this rambling the only time I notice a delay is when I shoot in very rapid succession.

Hope this helps!

My apologies Paul, for not remembering your post as the source.

And thanks for the comparison test. I missed that thread.
 
Do you folks format the card as soon as you insert it into the camera? I have had a couple of incidents of an image not recording. Just one picture. Then it is OK for the rest of the day, evening, whatever.

Do you re-use your cards? I am strongly tempted to do that.

There as many options as there are users!

My A77 got a brand new card and I have ever used that card in that camera. Format the card in camera as soon as I got them.

By "re-use" I understand using old cards in your new camera, I would not do that, but I don't see any problem with it either. It should work just fine, but if the cameras are both Sony, you might get into trouble with image numbering. If that matters to you, there was a setting in your camera that you could change.

i do agree that the Sandisk Extreme Pro is a good card. Write speed is good and so is ready speed (for read, i can get constant 70+ MB per second when copying to my laptop, with peaks exceeding 90MB, so this makes photos transfers fast)

You don't have to get the 64GB unless it works out to be cheaper than 2x32G or if you don't mind carrying more cards, 4x16G

i have a Sony high speed card but no tested yet, so I can't comment on that

There has been couple of good deals on Amazon during the past week or 2 and you might want to track them if you are not in a hurry to get it
 
Sorry maybe silly but what do you mean format the card in the camera I have never done this and reading this I have had a few photos especially when shooting raw that won't open when I transfer to laptop is this the reason? And how/ why do I format the card?
Thanks for all your help on this thread

When you use a new card for the first time in the camera, the camera will ask you to creat a data base. Once done, used, download you new images to computerthen re-insert your card into camera, you'll want to format it in camera. I can't remember why this is better than deleting files and re-formatting on a computer but it is. (Found that info on this Forum a while back. Formatting in camera deletes all files and sets up the card for another round. The "Format" function is found under "Menu" then "Setup" then number "5". Press enter and it takes a few seconds then you have a fresh card.
 
Just a suggestion which may have already been brought up. i see some people buying a single 64GB or even a 128Gb card. In the event one card malfunctions or you are on a long shoot, It's always best to have at least one extra card with you. Instead of one 64Gb or one 128Gb, I suggest two 32GB or two 64Gb cards respectively. Another good reason to have two cards, at least, is to protect shots already taken and / or if I go out with a particular image to capture and I get it, then I'll pull that card and start with a new one so now I know where that shot is and I'll find it faster in post. I have one instance of losing all data on a card which I can only attribute to some malfunction in a camera as the card has worked fine ever since.

I got this for my not yet received (due in on Tuesday) A77II.

http://www.bhphotovideo.com/c/produ...DXPA_064G_A75_Extreme_Pro_64GB_SDHC_SDXC.html

It was a little cheaper when I bought it. It was 98 the day before I ordered it. Dropped to 89 the day I ordered it and when back up a few days later.

Finally got the A77II in today and that 64GB card is working fine in it. Looking at other posts here I always formated the card in my A700. I would periodically take out my CF card, transfer the files to my computer using a card reader and then after processing I would put the card back in the A700 and reformat it.

I just plugged the A77II directly into my computer via the USB cable and the transfer seemed to go faster than I got using the card reader. May routinely do that instead. However, after doing that I would still periodically reformat. BTW, I remember trying that with the A700 and I don't remember exactly why but I felt just removing and reading the card was better.

BTW, didn't have to wait to charge the battery since I already have three of the batteries for my A700. I just unboxed the 77II, attached the strap (always a pain), put in the card and a battery and powered it up. Oh, also attached a lens of course. I used my Minolta 28-75.

BTW, with today's acquisition this is what I have:

Sony A77II

Sony A700

KM Maxxum 7D

KM Maxxum 5600HS (D) Flash

Sigma 30mm f1.4 EX-DC

KM 100 f2.8 Macro D

KM 11-18 F4.5-5.6 D

KM 28-75 F2.8 D

KM 18-200 F3.5-6.3 D

Sony 18-250 F3.5-6.3 DT

Minolta 70-210 F4 (Beercan)

KM 100-300 F4.5-5.6 D

Kenko 2x MC7 DG Teleconverter

Haven't used the KM Maxxum 7D in years. Not sure of its operational status.
