Hi guys

I want to start shooting onto dual slots in my 5dmkiii (CF and SD), and I want to shoot to both cards in RAW.

Do any of you have any experience and can recommend the best type of cards for this job to make it the fastest possible. As from my understanding the dual shooting is going to slow the camera down a lot.

Thanks in advance
Gary
 
small jpg to SD and Raw to CF
 
You want to START shooting raw to both cards???!!

You should have been doing it for a long time.
 
Hi Jim

It doesn't really help me shooting small JPEG as I want to cover myself as best as possible.

Ryan, I have been shooting onto small 4gb cards accross 2 cameras, so I really don't understand your point and how it has anything to do with the question I am asking????!!!! I don't see why people find the need to have to make bitchy comments when I am simply asking for advice on what cards to purchase.

It's only now im moving onto 1 body so I have lost the protection from the other camera.

Most of the big name American pros only shoot raw to one card and JPEG to the other to save on the buffer lock ups.

I feel more comfortable shooting raw too both but to be fair you could easily get away with shooting raw and Jpeg.

Will only be as quick as the sd card sandisk 95mb are good

Hi Gary

I tend to use Sandisk or Lexar cards and have had no issues at all. I seem to remember the 5DmkIII is slower to write to the SD card than the CF card.

This Lexar card on offer http://www.amazon.co.uk/gp/product/B00UYZB45G?keywords=lexar sdhc&qid=1440827520&ref_=sr_1_5&sr=8-5 will be more than quick enough (and it's cheaper than the slower 30mbs card)...
 
Same as many, JPG on SD and RAW to CF, deleting any missed shots leaves them on the CF, so handy IF you mess up.

Apologies Gary, I thought you were a pro photographer. I must have you confused with someone else.

Why are you moving only to one body ?,even using to card slots doesn't give protection from gear breakdown :)
 
I do this at weddings, RAW to both cards. Anything else isn't redundancy as, if the CF fails, all you have are JPEGs.

It does slow down writing a hell of a lot - basically once the buffer is full you'll struggle to take more than a shot every one or two seconds. Generally this isn't an issue at weddings as you're rarely burst-shooting, the exception being things like confetti.

I use decently quick Sandisk CF cards (as I often use these alone for other things when I need better burst speed) and 45MB/s Sandisk SD cards when needed.

Perfect, just what I wanted to hear!

AFAIK, deleting an image will remove it from whichever card is selected for playback so make sure it's the right one!

No probs. I should add that the 5D3 has a decent buffer so you can always take a good few shots before the card write speed even becomes an issue.

I have faster 60MB/s SD cards for use in my 6D but there's no point with the 5D3 as it can't benefit from them.

I wasn't trying to be rude. I just think that if you are shooting for money then you should really shoot full-size RAW files to both cards (if you have a camera that has two card slots). And if you only have a camera that shoots to only one card then you should buy a camera that offers two. It's just mitigating as much risk as possible.
 
did canon hobble the speed on the sd slot? or is my memory buggered:D

And lot of pro do shoot J-peg,it all depends on which subject your shooting :)

Why Cliff Mauntner doesn't neither does his missus? There reasons for shooting raw and JPEG rather than raw and raw make a lot of sense as well.

They didn't deliberately hobble it I don't think, it was something to do with the processors in the 5D3 only supporting a single card slot and thus having to do some juggling to get the second slot in but the speed was limited.

It'd be nice if the SD slot was faster and UHS-1 compliant but it's not the end of the world and I'd much rather have it than not at all.

Slot 1 - RAW, Slot 2 JPEG - works for me.

That's a valid system but just not a redundant one. If you want true redundancy then you need to be writing the same format to both cards. When shooting important stuff like weddings I want total redundancy and RAW on both cards and speed limitations be damned :)

I'm sorry, I haven't got a clue what your talking about. I know what redundancy means but not in this context. Do you mean you want total dependency on both slots to shoot RAW ?
 
No I was just saying that, whilst storing RAW on the CF card and JPEG on the SD might be a faster solution than storing RAW on both, sometimes it's not really enough. If the worst happens and the CF fails then all you have are JPEGs rather than RAWs which, depending on the situation may not be adequate. When I'm shooting a wedding I want the RAW stored on both cards so that, if either fails, I still have the RAWs. This obviously is a far slower system but the trade-off is worth it to me in that situation, that's all I was saying :)

Why wouldn't it be?

Cards rarely fail when they do occasionally fail it you would still have the card with the jpeg backup, jpeg is a lot more flexible in terms of editing than you might think for one card with maybe a couple of hundred images it's probably not really gonna be a big deal. The advantage being every time you shoot everything is much faster.

In saying that I am too much of a scardy cat and shoot raw too both.

Quite right, sorry I am missleading people, also note that if I recall, removing a card and closing the door changes the selected slot, I.e if you close the door with only one card it will default to said slot, open it again and re insert your chosen card that may have been selected before and the slot will now have changed! I now tend to copy the images if removing the card and leave the door open or I forget and the selection changes without knowing, then it gets confusing!
