Best CF card for my money

Lexar cards may cost a bit more than some other brands, but are well worth the small extra cost. Unlike less expensive (and some more costly) CF cards, my Lexar cards have never failed me.

For Shame

Mine died after four months of occasional use while on a weekend break. I'll stick with San Disk in future.

Fill 'er up!


from St. Louis, MO, USA  -  Semi Pro

I bought a bunch of these cards at a great price thanks to a manufacturer's discount. The loads of extra space comes in quite handy when shooting events, or even on my recent 2-week european vacation. Shooting is FAST and there continuos shooting comes off so much better than with my other, lesser-quality CF cards. On vacation, though, using my old Canon XTi body, every one of these cards had 1-3 error images, usually right at the end of the remaining space left on the cards. I had zeroed out the cards and formatted them before the trip, so I'm going to assume this is a potential problem with the cards. I didn't loose any important shots, but this issue holds me back from giving it a 5-star rating, much less give it props for reliable performance, but I won't necessarily count it down for that. Overall, I got great value for my money, and I'd recommend the cards on that note, but I'd advise people to test the card to the end of its capacity to be sure.


"LEXAR Pro 4GB 133X is quite amazing..."


from Miami, Florida  -  Pro Photographer

I'm a professional photographer working for a major daily in Miami and quite frankly, the LEXAR 4G 133X is the fastest card I've ever used. Ever since I've been using digital camera, the LEXAR brand has been a constant with me for its reliability, and now for its speed. Just watching the images download rapidly on to my computer gives me the chills, especially during those excruciating deadline moments. I also use the LEXAR brand SDHC for video-( I have to shoot video now in order to keep my job), for it's seamless imaging and reliability. In conclusion, kudos to the LEXAR brand, because it's the only brand I use.. P.S... I've used other brands before but unfortunately, i've had problems with them, specifically data error or lost images. I can honestly say that this has never happened using the LEXAR brand.

The first CF card I use on a shoot!


from Mesa AZ.  -  Pro Photographer

I have been using CF cards from two other manufactures in my camera. Now I am in the process of changing all of my cards over to Lexar 4GB cards!


Would Buy Again


from Hammond, LA  -  Photo Enthusiast

I have only had the Lexar 4 GB 133X High Speed Series CF Card for about a month. I have used it three times, shooting indoor, outdoor and night pictures with a Nikon D300. It has worked very well. Download onto my computer from the D300 is quite fast. No delay. And, of course, the price was right. I'm satisfied. jdow32


reliable & quick buffering on my D-200 !


from Roswell,Ga  -  Photo Enthusiast

Convienient storage size for quicker down-loads. Keeps one from putting all your eggs in one basket!


Fantastic Product


from St. Paul, MN  -  Photo Enthusiast

I purchased a pair of these cards during a recent promotion. These cards significantly decreased the "write" time for images from the camera internal buffer to the card. These cards provided a noticeable improvement in the performance of my DSLR in the field. I have put a little over 2000 images on each card in the last month and have not had a single issue of failure or poor performance. I highly recommend Lexar cards and have only glowing things to say about the 4gb 133x cards.


This Lexar 4 GB, 133x is Fast


from Sunny San DIego, CA  -  Photo Enthusiast

I love the Lexar 4GB CF. I use a USB interface to download pictures from my camera. I also like the Lexar as a means of backing up all my digital photos. These little items are much easier to store and carry around than CDs or DVDs.


as good as I've used


from Provincetown, MA  -  Pro Photographer

As photographer for an art museum and for individual artists and galleries I often shoot openings, fundraisers and other unrepeatable events. Reliability is key and quality of reproduction of art works and installations needs to meet the test of critical eyes. This card does its part in getting the job done without fail!


Reasonable price for quality product
