Got the camera used, and it had everything except the flash memory card. I went to Amazon and searched by the camera name, and they had cards… Oops! Wrong! They tricked me! I bought a nice 32Gb SDHC card…an’ it don’ work! Pfui! Can someone here (SDMB, font of all knowledge!) point me in the right direction? Million gracias! ---

The 30D requires a CompactFlash card, completely different format. Where did you find someone recommending SD cards? I believe maximum supported size is 128G. Not sure what speeds are most useful. ---

Amazon, durn 'em. I searched by the camera name, and that was one of the items they displayed. I’ll look again and make sure to specify CompactFlash. Thank’ee! ---

Yeah, I was going to say, those took Compact Flash cards. I don’t know what memory limits they have. That’s a camera from like, I don’t know 2005? I could look it up, but I assume there are limits to how big of a card you can use is. 128G seems high to me. I only use 64GB cards with today’s generation of cameras. But it could be right. ---

Going back to Amazon and searching with the new term, I found a nice 64Gb puppy for a comfortable price. Hope it works! Thanks for advice! ---

You know they make CF to SD card adapters, right? That’s what I use in my Eos 7D. ---

Nope, I didn’t know that. That would have been a good work-around, but too late now, I sent off for a CF card. Thank you anyway! (Is there anything the SDMB collective _doesn’t_ know?) ---

In fact, these days I only buy Micro SD cards. For my EOS 7D, I put the micro SD in an SD adapter, and put that in a CF card adapter. There may be some speed reduction as a consequence, but I don’t know that it happens at all. And the advantage is that the same cards can be used in all my devices. I even have Micro SD to USB stick adapters. ---

And boy are those Micro SD cards micro. Don’t handle those things with Parkinson’s! ---

For sure they are tiny. When digital cameras were new, most used CF cards. I remember buying 128 Meg CF cards from Fry’s and thinking $100 was a bargain. Now a 128 Gig micro SD card is less than $20. ---

Also, I’ve found that when you search on Amazon, you get all sorts of results that “sort of” match what you are looking for; not simply the specific results you want. Be very cautious when searching for less common items on Amazon. ---

Or you get thousands of results that match in no way whatsoever. ---

I sure learned that’n the hard way! But a Google search didn’t do any better. Phoomph!
