Why is my friend getting "busy" on her Canon?
May 29, 2012 20:06:51 #
On week-end my good friiend says she loves her Canon DSLR - model # unknown- she spent about $700 for body and lens kit sold at Costco last winter.
She uses 3200 ISO generally; someone told her she needs a faster and larger card to sole the problem. Went to 3200 to avoid low light problems, etc. However she shoots mostly her kids at play.
Would like to know the relationship between processing time in-camera and card specs. Target is to eliminate "busy" warnings altogether.
anyone care to share opinions about this topic? TYTY All

I doubt the ISO has any real effect. My first guess would be the memory card speed. There is probably an explanation in her owner's manual.

Try using a faster class card; owners manual is a good place to start for minimum card speed supported.

The card speed seems to be her problem. Cheep cards are slow. Go with a good name with faster speed. ISO has nothing to do with it, I can't see any reason to use such high ISO shooting the types of pic you said. The higher the ISO the more noise (grain in the film days) there will be in the picture

How many frames per second is she shooting. If she is continuous shooting, depending on her camera it will say busy till it records the images she has taken. Look up in the manual and it will tell her how fast the camera will process the shots. If she is shooting in raw it will take longer also. I would guess her camera is not capable of recording as fast as she firing if she is capturing her kids at play.

Tell your friend to buy an 8-16 gig class 10 SD card. They are dirt cheap now and they are plenty fast enough. No more "busy" messages. ISO has nothing to do with transfer speeds.

So are you trying to change what you are getting from your camera, or alter your friends state of happiness with the results she's getting?
Logic tells me that if an increase in ISO means that my camera indicates that I have fewer exposures available than at 100 iso, then ISO does increase file size and write times. But then I may just be old and foolish.

Probably card speed and file size, raw + JPG takes a lot longer to write than JPG alone, Bob.

Do the following:
1) Get a faster memory card. Probably the biggest and most obvioys factor here. See posts by others.
2) Verify that she is shooting just JPEG, not RAW or both file formats concurrently.
3) While not a factor in the "busy" issue, I agree with MWAC. 3200 ISO is usually not necessary, especially for taking pictures of kids. Put the camera on AUTO and set the ISO to no higher than 400.
4) Ask a knowledgeable friend or the geek in the camera store to take a look. It could be a defect in the camera, but I doubt it. My money is on #'s 1 and 2 above. Possibly both are working against her.

Bob,
As others here have pointed out, the card seems to be the main issue. I routinely use SanDisk cards but any name brand will do. I get them in 4-16GB sizes with a class 10 rating. For my Sony, I use the Sandisk Extreme, SDHC I. It has a transfer rate of 45MB/sec which is plenty fast so the camera really shouldn't bog down between bursts. I use similar type cards in CF format for my Canons.
The ISO setting shouldn't affect transfer rate but why is she shooting at 3200? That seems kind of high for kids at play. If these shots are outdoors, 400-800 ISO should be fine even at higher shutter speeds, maybe 1600 if the light gets really cloudy or the kids are in shadow. Depending on her other settings, 3200 might get a bit grainy.
PD

Hey Ziggy, being old and foolish is a fringe benefit of surviving this long. We earned this right. Be proud!!
Yes, you are correct. Increasing ISO can impact filesize, but probably not enough to notice any difference in write times on a per image basis, much less enough to create the "busy" problem described.

I had never looked at the number of photos left display, with different ISO settings until I read your comment, and my numbers also change when I vary the ISO.

My guess would be that she is shooting in raw - or the card is defective.

As you or she is looking at memory cards stay with the main brands. Avoid cards that have 3 letter names. Class 6 cards sometimes are faster than class 10 depending on manufacture. The amount of information that the camera is asked to record could also be the issue. RAW is going to record more info that jpeg. Learning to think as your camera thinks is one element of knowing your equipment.
