Shopdigi CDA Compact Flash CF Type 2 Thick Card Adapter for SD cards. NOT for Devices with CF Type 1 Thin Sockets

Works great with my Canon 7D. You will need to format any new SD memory card you use in it. (Like if you took photos with another camera, you need to format that SDHC card before using it in another camera with this adapter.) The card is thick, so it fits very snug in the Canon 7D compact flash card slot. I actually removed the back sticker label on this adapter, so it would make it slightly thinner, and it now inserts and removes better. Make sure your older camera accepts Compact Flash CF Type 2, otherwise this card will be too thick.

I have a Nikon D300 and often shoot a lot of images or shoot combined jpeg and RAW and wanted to use something larger then my two 8GB CF cards. Since I own a few 16GB SDHC cards that I use between a smaller P/S camera and a SD/SDHC HD camcorder, I decided to give this adapter a try to avoid buying larger CF cards that can only be used on my Nikon D300. The adapter is well made and solid. Goes in and fits perfectly in my Nikon D300 card slot (ejects easily too). I see no degradation in performance and and fact I do see an obvious gain in writing speed, since my SDHC cards outperform my older CF cards which I've had quite a while and are of the older/slower generation of CF card. The transition to using the SD adapter with my newer SDHC cards was seamless and other then one extra step of having to remove the SD/SDHC card from the adapter to read it if you do not have a card reader capable of handling CF cards too, this adapter does the job perfectly. I in fact am considering buying a second adapter of the very same model as this one to avoid changing SD cards out in the field and to save a bit of time. Bottom line, this works like it should and I highly recommend it at only about $15. Seems SD cards have become the predominant card type for most devices now (even newer Nikons similar to mine now take an SD rather then a CF card) and as SD prices go down, this adapter is the way to go for your CF card camera. Time will tell how this adapter will hold up inside under continuous use of putting in and taking out an SD card. I do have a card reader that accepts all of the card types, so, maybe that will be the way to go (read from the adapter directly rather then remove the SD card) to save a little wear and tear over time.

Despite a few bad reviews, I decided to take a chance and purchase this product to use in my Canon Rebel camera. I wanted to be able to use the same SD/SDHC cards that my wife uses in her compact canon so that we could exchange cards should we ever need to (sometimes one or the other of us forgets to bring an extra). Also, It's a lot easier to store SD-size cards than the much larger CFs. The adapter has worked perfectly with the three different (types and memory size) SD and SDHC cards I have tried. I had to format the cards in camera first in all cases but after that there were no problems. I think, like others have suggested, that the adapter might have caused the camera to operate slower but I have not had a chance to compare similar cards so there is no way to be certain. Also, I was using a flash when I did my only serious picture taking so far and the flash recharge determined the camera speed, not the memory card. Otherwise, just shooting test shots around the house without the flash, the adapter seems to perform very well. A nice side benefit is that the card reader I have in my computer is older and can't read SDHC cards but it can when they are in the adapter in the CF slot. If I planned on taking series of rapid shots I think I would get the fastest CF card I could and bypass the adapter, but for normal picture taking the adapter works perfectly. If you are going to use cheaper, slower cards in your camera, there's probably no point in worrying about whether the adapter is a little slower anyway.

OK, I like the convenience this card provides for me but I had an issue with it. My daughter tried to insert it into my Canon 5D with very little luck. I have never really had a problem. I would imagine she put it in with a little pressure on one side or the other. It bent one of the pins in my Camera. I was in a panic this is a $2000 camera and for sub $20 card to cause damage like that its not worth the chance. I did get the pin straight and haven't had anymore issue. Just keep in mind that the holes for the pins are not 100% precision and can cause issues. Its a great concept to convert a CF camera to a SD and its cheaper to purchase the newer smaller card designs. Not sure why CFs are so expensive except there are fewer of them made now. Overall I will give it a 3, only because of the damage. It works well other then that huge issue I had. Update, not realizing I had left this review for this card before it reminded me of the issue I had the first time. Well, guess what, I purchased another, I didn't quite learn my lesson the first time. So I purchased one for my daughter's camera. We went to put it in and it stopped she started to push on it and I stopped her. I now know why I am very ginger about putting cards into my camera. Because the first one bent pins on mine. Thank god I stopped her. I tried it on my camera same issue. Needless to say, I will not be using this card and changing them both out. Good, luck two cards two cameras and neither card worked well. Also reducing the star score from three as I gave them the benefit of the doubt to a 1. Wish I could go lower as to say do not use this product.
