So far so good Review by Jason "Jason B"
Have had the card now for a little more than a month. I bought it to shoot RAW movies. The card has been amazing. I also shot two 19 hour timelapses a week apart and it performed great. This is also my largest CF card which happened to be great with the timelapses as I didn't have to change the card that often. I know there has been mixed results with these cards, but I'm happy with mine, and I know Komputer Bay is willing to make it right when their cards fail. ***This review was posted on:*** (Posted on 17/06/2014)
Works great for RAW video in DSLR Review by Spencer D. Blesi
I was a little worried about purchasing a Komputer Bay card, but honestly, it's worked out great. I've only had a few write issues, but I think it more of a magic lantern thing. Used it on multiple shoots already. If you are looking to record RAW, you can't beat the price. ***This review was posted on:*** (Posted on 17/06/2014)
IT WORKS! WOW! 4K 1DC Approved : Review by Kevin A. Falk
I was really hesitant about these cards. But after thorough testing, they seem to be holding up fine!
I formatted it right away in camera and its been rocking ever since.
4K approved on the Canon 1DC. Shot 20 min straight with no problems.
Camera warmed up but its said to do that with 4k recordings in general.

Was weird that it was shipped in a large 11x14" padded yellow sleeve.
Thats weird because it was just the card in a small clear standard memory card case inside. No paper work, no nothing.
But it works! ***This review was posted on:*** (Posted on 17/06/2014)
Komputerbay 1050x 128G CF card Review by peterchi
This card is amazing, On CrystalDiskMark 4K Sequential test I get just over 100mbps read and 200 write.
I highly recommend this card, I shoot Magic Lantern on my Canon 7d raw video. ***This review was posted on:*** (Posted on 17/06/2014)
As the title states, with this card I get continuous shooting with my MagicLantern raw hacked 5D Mark III at 1080P 24fps. Won't do 30fps continuously though, but that's not an issue for me. Probably gets an average of 94mb/s write speeds. Not exactly wha Review by Hirum Horkweller

great for raw video Review by Amazon Customer
Worked as expected... Im using it with a 5D mk3 And magic lantern to record raw v (Posted on 17/06/2014)
Almost perfect Review by Klement
The item ordered was a CF card: Komputerbay Professional 128 GB CompactFlash 1050X.
One of the fastest card you can get for money.
I got it in a resonable time, but it appeared however to be not-so-fast, and in this case
far below specifikations.
I complained about this, and shortley after I had returned the bad card, I recieved a new
This card was absolutely O.K. <
So al in all: I'm absoluteley satisfied. ***This review was posted on:*** (Posted on 17/06/2014)
Fantastic Card, high speed, works with Magic Lantern perfectly Review by Nate Volk
I've been using these cards in a production environment for the last few weeks, running magic lantern RAW video on my Canon 5d MKIII. They run great, full 1080p @ 30fps and the storage size is great! Being able to shoot most of the takes on one card is such a time saver. A little tweaking with the camera settings, and running the latest builds gets the most out of these cards. One gotcha though: you have to have a newer UDMA 7 compatible card reader, or you won't get the rated performance. Make sure to format ExFat, and you are good to go!

Canon settings for optimal performance:
Set picture size to raw off, and jpg small in the canon menu.
Run the hacks in ML if you need more performance.
I get better performance with live view ON.
Run at least the 8/2 build, there are huge buffer performance increases
Set canon record menu to 1080/30 fps and change fps in ml menu if required

All in all, its a fantastic product. I felt uncomfortable taking the risk of a brand I hadn't heard about, but it is well worth the money saved. I won't be going back to Lexar or SanDisk again, these Komputerbay cards are awesome! ***This review was posted on:*** (Posted on 17/06/2014)
UPDATED REVIEW (5d mkiii RAW) Review by C. Edwards
I have been using these cards in the field on a documentary for the last couple of months and, at first, I was experiencing problems and inconsistencies which prompted a hasty review of these cards. After messing around with the ML settings for quite a while, I discovered that the cards work just fine as long as I turn off most if not all of the ML features such as fps override, global draw, etc. I have been meaning to update this reveiw for a while but have just been too busy filming with these cards. ***This review was posted on:*** (Posted on 17/06/2014)
Updated: Does not Deliver (Canon 5D MK III Raw Video) Review by N. Pickett
UPDATED: When I originally posted the review below I did not receive a response from Komputerbay by email or when I tried contacting them by phone. Before sending back the card I decided to call one more time and when I did get an answer things worked much better. Here is my update. After using the July 22 build of the ML RAW nightly builds and going through the steps described to me over the phone with Komputerbay customer service; I have been very pleased to say I have experienced no dropped frames with the following exceptions, which I should point out are not the fault of the card but the nature of bleeding edge software (that is still amazing) just an FYI: When there is less than 1gb of card space left or if I start my recording while in a menu.


I began shooting with the ML RAW using a 5D Mark III around mid June. I tested the SanDisk Extreme Pro Cards and Lexar 1000x Cards. Both performed very well and because of higher write speeds I purchased some Lexar 1000x Cards with limited storage capacity over the San Disk Extreme Pro. I purchased the smaller capacity cards with the hope that the price for faster CF cards would eventually come down.

It wasn't until KomputerBay released their 1050x cards I thought I may give them a shot, as previously they did not seem to have the write speeds or consistency necessary for ML RAW. After shooting with the new KomputerBay 128GB 1050x card for the past three days I am disappointed. It is clear that it does not perform as advertised. Write speeds under 75 mb/s this card can handle OK, but will still have some drop outs. More importantly, anything above that and you will frequently experience multiple dropped frames (So if you plan on shooting 1920x1080 24fps or higher this card WILL NOT work for you). Advertises 100 mb/s write speeds <--- this is not true for the card I just received; in fact, I was unable to capture sequential clips without dropped frames when shooting 1080p. This has never been the case for my Lexar 1000x cards nor when I was testing the San Disk Extreme Pro Cards. Maybe I have a bad copy? I would be happy to try my luck with a replacement; however after contacting support they will only let me return the item for a refund.

Until there is more consistency with the products from this company I can't recommend purchasing anything from them. It is not about getting what you pay for it is about false advertising and misrepresentation of a product.

Your time and money is better spent on a name brand card that you can rely on. ***This review was posted on:*** (Posted on 17/06/2014)
Best Card for performance and cost Review by Michael
I have given 2 KOMPUTERBAY 1050X 128 Gig compact flash cards the most demanding tests in assessing whether or not it is a card I can use professionally for writing 1920 x 1080 continuous 14 bit raw video files on my Canon 5D Mark 3's. The card wrote 128 gigabytes of data without a dropped frame in continuous use at both 24 or 25 FPS. I was using Magic Lantern's alpha software with the cameras and cards. For stills or video this card met the demanding use of a professional. While using their early 1000x 128 gig card I had some dropped frames and inconsistent performance and the company refunded my purchase when the cards could not deliver. These newer cards have delivered perfectly.

It's difficult these days to find a product which delivers peak performance at an affordable price but these cards have. ***This review was posted on:*** (Posted on 17/06/2014)
Works great for shooting raw video with Magic Lantern on my 5D Mark ii Review by M. Martin
Very happy with the card - it's fast and it allows me to record raw video at 1600x900 (or a little higher res) using Magic Lantern on my Canon 5D Mark ii ***This review was posted on:*** (Posted on 17/06/2014)
Great value, great performance Review by Marcello A.
I have a Canon EOS 1D Mark III. This card writes fast, transfers fast, and is the least expensive per gigabyte of any I've seen at this speed rating. Love means never having to change CF cards while shooting an event. Bravo! ***This review was posted on:*** (Posted on 17/06/2014)
Card crashed half-way through photo shoot Review by Rick
Using Nikon D3x, RAW uncompressed. I was in a photo shoot with a professional model when the card crashed (less than 100 shots into the shoot). Camera stated the card needed to be formatted, which had been done previously. Lost everything. They're for sale if anyone is interested. ***This review was posted on:*** (Posted on 17/06/2014)
Works very well so far, Review by omid yousefian
I bought this a month ago and used it on my Nikon D800 to take wedding videos and RAW pictures.
Works fine.
Cheaper than other brands. ***This review was posted on:*** (Posted on 17/06/2014)
Corruption problems Review by tam tran
EDIT: Komputerbay has since replaced the faulty card and it seems to work much better.

Bought this along with the 128Gb SD card to be used in the Canon 5D Mark III. The camera is running the latest firmware 1.2.3 and is set up to record RAW to CF and JPEG to the SD card. So far, I have had more problems with the card than all others combined. The camera has problems writing to and reading from the cards after it becomes corrupted on its own. The only way to get it to work again is either by taking the battery out, even then the camera still has a hard time reading from the card in playback mode. In the end the only option is to reformat the card until the next corruption occurs. Just today I've had to reformat the card for the second time while on holiday in Wales. Needless to say the CF card is as good as a paperweight while the SD card is flawless. ***This review was posted on:*** (Posted on 17/06/2014)
Better than the previous card Review by cvg1arr
Tried the 128GB Professional COMPACT FLASH CARD CF 1000X 150MB/s Extreme Speed UDMA 7 RAW 128 GB last fall and returned due to the VERY LARGE number of corrupt images.

So far this card has produced only 1 or 2 corrupt images out of over 15K. (Possible those 2 were my fault taking the card out too soon) ***This review was posted on:*** (Posted on 17/06/2014)
Works for Raw On 5dMarkIII Review by Erik O'Brien
I have tested two of these cards, both were able to record more than 5 minutes of raw footage at 1080p on my 5Dmark III... Stands up to what it says, 5 stars! ***This review was posted on:*** (Posted on 17/06/2014)
Best CF card for the price Review by Keith
This card works Perfectly. I currently use this card with a Canon 5D Mark III with the magic lantern hack for shooting video in RAW. This card has given me no troubles. I am very grateful for Komputer Bay's product. They deliver and save me money from bigger name companies. I currently own a few higher capacity/ write cards by KB and plan on getting more soon. ***This review was posted on:*** (Posted on 17/06/2014)
Inconsistent with Magic Lantern RAW video Review by Everett Glovier
I have a 5D mkIII. Initially, after messing with it for a very long time, I was able to get about 12 minutes with no frame drops. But, as it get closer to filling, the card slows down. It also gets very hot (many people say this is normal). I also had corrupt files occasionally, and the card froze finder and then had to be reformatted.

If you have this card, I hear their kustomer service (see what I did there?) is great! I just don't have the time to send cards back and forth until I get a working one.

It is very inconsistent and I would not recommend it for professional jobs. I ended up going with the Lexar. ***This review was posted on:*** (Posted on 17/06/2014)
Excellent for regular photography Review by sirchcap
I have yet to prove it's capability taking raw pictures in bursts. Overall I'm satisfied with the product, i'll recommend this product to my friends. ***This review was posted on:*** (Posted on 17/06/2014)
Good speeds, great for Magic Lantern Review by Joey Cohen
I've had good speed benchmarks.
Not always consistent but good enough for 1080p RAW on the Canon 5Dmk3.
Haven't had frame drop yet..

Will surely get another one soon. ***This review was posted on:*** (Posted on 17/06/2014)
Not a bad card, Review by Renwick

Great Value Review by kdet
I've been shooting with these cards for about 6 months now and love them. The first card I received could not be formatted, but the replacement has worked perfectly and I've purchased another from this company. I primarily use these cards for shooting raw video on a hacked 5D3, and know several other shooters who regularly use these cards in production environments. ***This review was posted on:*** (Posted on 17/06/2014)
HAVE ZERO FEAR Review by Adam J. Gibgot
I purchased this memory card in lieu of the far more expensive Lexar model, and I can honestly say it might have been one of the best purchasing decisions I have ever made. This card is every bit as reliable at a fraction of the cost. Their customer service is also extraordinary as I initially ordered the 256gig card but someone from Komputerbay managed to track me down to make sure my camera would read this card properly. I use a Canon 5D3 and as it turned out there was a Canon compatibility issue with the 256gig card at the time of purchase (check to see if it's been resolved if 256gig is your preference with a Canon 5d3 body). Regardless, Komputerbay was all over it and made sure I was making an informed purchase. I ended up opting for the 128gig CF card and the five stars above sums up my overall experience. ***This review was posted on:*** (Posted on 17/06/2014)
Works great with 5D Review by thomas dodson
I am a professional camera operator that was looking for a large inexpensive card to work with my canon 5D mkIII to shoot RAW video. I have been using this card for about a month now with zero issues. It's fast, large, and one hell of a value. I am recommending these card to all of my friends who don't want to break the bank on media. ***This review was posted on:*** (Posted on 17/06/2014)

Great card at a great price Review by MrHarleyDavidson
I bought this card (2 of them) a few weeks ago and I am thrilled with the performance and price. At less than half the cost of the competitor it was like a BOGO deal. Shipping was swift and the product has performed flawlessly since I started using it. Another great value on Amazon. ***This review was posted on:*** (Posted on 17/06/2014)
Pretty disappointed with quality control, Review by Travis
Ordered 2 cards. 1 would not do RAW at all and even corrupted some of my normal filming footage with stock canon firmware. The other was better but could only get about 50-60 seconds of RAW before skipped frames. Sending these 2 back to amazon. Thank god for the easy returns. I am going to give Komputerbay another shot. I'll just order 5 cards this time and hope 1 is good enough to keep. 1 star for now... ***This review was posted on:*** (Posted on 17/06/2014)
UPDATE as of June 4th, 2014 Review by Eric
UPDATED June 4th, 2014:
Card went bad on me and got a warning that said "Card cannot be accessed" when put in my camera. My computer also wouldn't recognize the card. Contacted Komputerbay and got a quick reply from their tech team who said (and provided provable forums) that the card reader I was using (Lexar dual slot usb 3.0) was corrupting cards. They then recommend that I get the Kingston card reader. I sent my card to them for replacement a couple days ago, and just got an email back saying that I will be shipped a new card in 0-3 days. While it's unfortunate that my card became corrupted, I still give credit to Komputerbay for solving the problem!

Just received it in the mail today! Will try and keep updated, but it worked like a charm! Popped it into my Magic Lantern'd 5D Mark III and it started recording full 1920x1080 HD in 24 without any hiccups whatsoever! Have it paired with a 128GB KomputerBay SD, so needless to say I have a lot of storage on my camera now :) If I had to make any bad comment, i'd probably say that my camera boots up a little slower now (about 4-6 seconds) but i'm assuming that's more a ML thing that a card thing ***This review was posted on:*** (Posted on 17/06/2014)
5d3 raw video works flawlessly Review by Matthew J. Ziniel
Purchased this card due to its cheap price relative to speed in order to record continuous 1080p raw video on the 5d3 at 24fps. It does so flawlessly with no dropped frames...ever. Also, I have also purchased a 64gb KomputerBay 1000x card and never have had any dropped frames with that one either. Highly recommended. If for some reason you did not receive a fast enough card for continous raw, I have read that you can send the card directly to komputerbay and they will make sure you get a fast enough card. Highly recommended. ***This review was posted on:*** (Posted on 17/06/2014)
Komputerbay rivals any other! Review by David Marroquin
Have had nothing but a great experience with this card. I'm shooting 14bit Raw footage on my 5D Mark III (via Magic lantern). It requires 82MBs/sec write speed and this card handles it with ease. I would definitely recommend this card! ***This review was posted on:*** (Posted on 17/06/2014)
Works well, though 1050x claims are a bit exaggerated, Review by Brandon Li "Run/Gun/Shoot"
Used on 5dmkIII Magic Lantern Raw. I have been able to record 1920x1080 continuously, filling up the card with a single take. No dropped frames. However, I am not able to record higher framerates at or above 95MB/S (approx). Performance is about on par with Lexar 1000x cards.

I got occasional bad frames when recording in FPS Override mode to enable the 3x zoom, but this may be the fault of the hack rather than the card. ***This review was posted on:*** (Posted on 17/06/2014)
So far so good Review by BTO "bthomasy2m"
I knew we were taking a chance purchasing a 128GB 1050X CF Card from this relatively unknown company.
We have had good luck with their 64GB CF Card so we jumped at this one and are pleased so far.
Spending 50-70% less than many other cards with similar specifications just made financial sense...and seems to also make
sense from a performance metric as well. We knew Komputerbay has a great reputation for standing behind there products so we felt there was little to no risk. We are happy customers. ***This review was posted on:*** (Posted on 17/06/2014)
Great product so far! Review by Experienced Musher "musher"
I purchased this on a recommendation of a good and reliable friend of mine... and fellow photographer. SO far, this item has been flawless. I have purchased 2 of them, using them both in my Nikon D3S and they work great. No errors, no corrupted files. I was a bit hesitant to buy such big cards, just in case... no one likes to lost this much data... but so far, awesome performance. I think if I were going on a big once in a lifetime trip, I would likely use the 2 in duplicate mode, just in case, but still, having 128GB should be plenty for any trip. Thumbs up! ***This review was posted on:*** (Posted on 17/06/2014)
