The DigiCase is the Ultimate DIT/DigiTech Case

People always ask us what the best way is to customize their DigiCase Pro. We've been using the TrekPak dividers with great success. They are easily customizable to create nice compartments under your DigiPlate Pro to store cables, hard drives, a DigiShade Pro, etc. We recommend accessorizing the bottom of your DigiPlate first so you'll have a better game plan when figuring where your dividers can and can't go. The TrekPak dividers can be purchased at both B&H and Amazon for $95.


CF vs. SD Cards: Which is faster? You’ll be surprised.

Our founder, Dana Neibert, just returned from a commercial shoot in which he ran into a problem that he normally doesn't encounter. Usually, he shoots tethered which for the most part is instantaneous feedback as each image pops up on the screen as he shoots. But last week he shot a job where he was shooting to the CF memory card and shooting about 32GB every 15 minutes at which time each 32GB CF card had to be ingested into a computer so everyone could do a quick review. But waiting for 32GB of images to import while precious daylight was changing was not ideal. He was using the fastest SanDisk Extreme Pro CF cards which can transfer data at up to 160MB per second. Using what is usually regarded as the fastest CF card reader, the Lexar Professional USB 3.0 Dual-Slot reader, each card was taking about 3.5 minutes to import into Capture One Pro. That doesn't seem like a long time unless you have 25 crew and clients standing around anxiously waiting to see the latest images. So we did a test this week as he will be shooting for the same client again in two weeks and wants to cut that time in half if possible. Doing a little research, we found that 160MB/s cards are the fastest CF cards out there. It doesn't really matter what brand as they all more or less use the same chips inside and they have to base their speed rating on practical tests or risk losing all credibility. We've always used SanDisk Extreme Pro CF cards but as far as we know the Lexar Professional CF cards perform just as well. Also, history has always dictated that CF cards outperform SD cards. But we decided to try a little SD card called the Lexar Professional 2000x SDHC/SDXC UHS-II. The speed rating on this card is 300MB/s which is nearly twice as fast as the fastest CF cards. But can an SD card really perform that well? Here's what we found. We filled two 32GB cards with raw camera images. The two cards were the SanDisk Extreme Pro CF and the Lexar Professional 2000x SDHC/SDXC UHS-II. The cards are rated at 160MB/s and 300MB/s, respectively. Below is a chart detailing the transfer speeds from each card to the latest MacBook Pro Retina with an SSD rated about 900MB/s which is more than adequate for both of those cards. You can see that CF card beats the SDHC/SDXC card using the trusty Lexar Professional USB 3.0 Dual-Slot reader. The internal MacBook Pro SD reader nets about the same import speed for the SDHC/SDXC card. But the SDHC/SDXC card really blows away the CF card once the dedicated Lexar UHS-II USB 3.0 reader is used. Next we checked the in-camera performance of the SDHC/SDXC card versus the CF card. We wanted to see if there were any compromises in using an SDHC/SDXC card instead of the trusty workhorse CF cards. We used a Nikon D810 which has become one of the new standards in commercial photography as it produces very large 36 megapixel images. Each card was formatted in camera and the camera shot at five frames per second until the buffer maxed out. Here's what we found. You can see the CF card barely/slightly outperforms the SDHC/SDXC in the camera. But with the price of SDHC/SDXC cards vs. CF cards and the import speed to the computer, the SDHC/SDXC card is clearly the way to go—especially when you start going to the higher capacity 64GB and 128GB cards those transfer times will double and triple. The Nikon D810 SD slot speed is only UHS-I but as cameras start to implement UHS-II slot speeds, you can expect the SD performance to greatly increase. By the same token, we're pretty sure CF cards will be introducing faster speeds in the near future to keep the race even. You can see the UHS-II card on the left has additional pins that the standard SD, high speed and UHS-I SD cards do not have. Most likely these extra pins are providing the extra bandwidth to help the UHS-II cards achieve these high transfer speeds. Like we stated above, we're really not married to any brand of memory card. But you will want to probably stay with better known name brands like SanDisk and Lexar as they do produce a quality product that, especially with memory cards, you won't want to take chances with. We chose the Lexar SDHC/SDXC card over the comparable SanDisk SDHC/SDXC as for some reason the prices are really far apart and the Lexar card comes with the ultra high speed reader. Here's a bit of a roundup of all the cards and readers covered in this article.

Put your DigiCase or Pelican case on any stand or tripod

The DigiCaseMount will allow you to mount your DigiCase, Pelican 1510 or Pelican 1490 case to just about any stand or tripod. The DigiCaseMount is made from aircraft grade 6061 aluminum which is both lightweight and extremely strong. The DigiCaseMount is secured to your case with 8 bolts to ensures a tight and secure fit. The wide footprint of the DigiCaseMount along with the 8 securing bolts gives a sturdy and strong base for your case to eliminate slop and flexing. Check it out here.  


DigiCameraPlate: Never lose connection again.

The DigiCameraPlate attaches to the bottom of your DSLR and uses a friction system to keep tether cables from pulling out the dainty connectors that most tether cables are equipped with. The friction system is so effective, you can actually carry the camera around by the tether cable. Our founder is a working commercial photographer and regularly lowers ten pound cameras to his assistants from atop ladders, cherry pickers, etc. (they don't like it—it makes them nervous). Check out the DigiCameraPlate here.


Drones: Five things you should know or use

Drones are becoming more and more accessible and affordable. You can go anywhere from a very expensive Freefly Cinestar Octocopter to a very affordable DJI Phantom 2. What most people don't realize is that now that you are airborne you are an aircraft and are subject to many of the same laws and regulations that a pilot flying a Boeing 787 is. To keep yourself on the right side of the law, a few tips from the APA and aerial photographer Cameron Davidson can be found here.


How to Avoid USB Tether Disconnects and Other Fantastic Problems

USB tethering with your camera has been around for many years. But as fantastic as it is, it comes with it's share of headaches; corrupt files, dropped connections, slow transfers. The biggest culprit is low voltage in your USB bus. Moving large amounts of data requires some power on the USB bus. When the voltage falls below spec levels, then you will start to experience issues. Sometimes with USB 3.0, when your computer sees the low voltage, it will automatically downgrade your bus speed to USB 2.0 speeds (10x slower) to compensate. We created a 6-port hub/repeater that works either self-powered or with an included AC adapter. Simply put the unit inline with your tether cable and it will keep you shooting all day long. As a self-powered repeater, it will take the power on the USB bus and amplify/repeat the power so that you can use 30+ foot long tether cables all day long. Since it is a 6-port hub, if you use multiple cameras or connect a couple self-powered drives, you'll want to connect the AC adapter as your USB bus will probably not be able to power all the devices. The repeater is USB 3.0 SuperSpeed and backward compatible with USB 2.0 devices. You can see complete specs here.
