Toshiba’s New microSD Cards Set a Speed Record, Feature 8x Faster Write Speeds

toshiba

As cameras get smaller, one of the places they can choose to save space is in the memory card department. A great case in point is the new Nikon 1 J4, which ditched standard SD cards in favor of their smaller micro counterparts.

The problem with this move is that microSD cards tend to be much slower than standard SD, but that might not be the case for too much longer thanks to Toshiba. Read more…

The Magic of Firmware: Canon EOS M AF Speed Boost Seen in Videos

canonspeedboost

Earlier this month, Canon announced that there’s a firmware update for the Canon EOS M on the way that will boost the mirrorless camera’s sluggish autofocusing speeds by up to 2.3x. Given that AF slowness is one of the biggest gripes EOS M owners have with the camera, the news was likely music to many a EO M owner’s ear.

If you want to see what this 2.3x looks like in real life, Korean photographer Daero Lee has published a number of comparison videos showing updated and non-updated EOS Ms focusing on things.

Sluggish Canon EOS M Autofocus Will Be Up to 2.3x Faster with Firmware Update

warpdrive

There was a great deal of excitement when Canon entered the mirrorless camera market with the EOS M last year, but much of the buzz evaporated when people began putting the camera through its paces. Although the camera features impressive image quality, one of the biggest issues is the sluggish autofocus that often gets in the way of capturing “decisive moments.”

If you’re the not-so-proud owner of a EOS M who constantly grumbles about the AF, here’s some news that’ll be music to your ears: your camera is set to receive a major AF speed boost by way of a firmware update.

A Comparison of Burst Mode Speeds and Shutter Sounds of Canon DSLRs

Canon’s DSLRs come with a variety of continuous shooting speeds, ranging from 2.5 frames per second on the 300D (AKA Digital Rebel/Kiss Digital) to a whopping 14 frames per second on the high-end 1D-X. If you want to get a taste of what these shutter speeds sound like on the actual cameras, check out the comparison video above by YouTube user dochero2005.

Speed Up Your Lightroom Editing Using a GamePad Controller

A little while ago, we introduced you to photographer Ed Pingol’s Cullinator, a Mac app that played nice with a PC gaming controller and helped you to significantly speed up your Lightroom workflow. As many of you pointed out, however, the Cullinator could easily be turned into a DIY project, and it looks like photographer Paul Snow of Photo Thoughts was listening.

In a step-by-step blog post, Snow details how to take a $25 Logitec F310 GamePad and customize it using the pad’s own profile tool until it works with Lightroom. Read more…

BTS: How National Geographic Captured a Cheetah Running at Full Speed

Back in June, a National Geographic crew was given the task of filming and photographing a cheetah running at full speed. While there are plenty of videos and photos out there showing this, the magazine wanted to track alongside the cheetah as it ran (rather than simply capture it from a fixed location). The short behind-the-scenes video above shows how they went about doing this.

Don’t Use SD Cards with Your Canon 5D Mark III If You Care About Speed

Photographer Jeff Cable purchased a couple Canon 5D Mark IIIs recently and discovered that although the camera offers both SD and CF card slots, you should avoid the SD slot if you want maximum shooting speed. He writes,

[...] for some reason unbeknownst to me, Canon decided to build the 5D Mark III with one very fast CF slot which supports the newer UDMA7 protocol and a standard SD card slot which does NOT support the high speed standard [...] Without UHS [Ultra High Speed] support, the top speed that can be achieved by the SD card is 133x. This is true even if you purchase a 600x SD card and insert it in the camera. The best you will get is 133x

It turns out that the camera will default to the slowest card inserted. So, if you have a 1000x CF card in slot one and any SD card in the second slot, the very best buffer clear that will achieve is 133x.

It might not be a big deal for most photographers, but if your line of work requires clearing the camera’s buffer as quickly as possible, it something you might want to be aware of.

Coming to a Camera Near You: Autofocus As Fast as the Human Eye

Contrast detection is one of the two main techniques used in camera autofocus systems. Although focusing speeds continue to improve, the method uses an inefficient “guess and check” method of figuring out a subject’s distance — it doesn’t initially know whether to move focus backward or forward. UT Austin vision researcher Johannes Burge wondered why the human eye is able to instantly focus without the tedious “focus hunting” done by AF systems. He and his advisor then developed a computer algorithm that’s able determine the exact amount of focus error by simply examining features in a scene.

His research paper, published earlier this month, offers proof that there is enough information in a static image to calculate whether the focus is too far or too close. Burge has already patented the technology, which he says could allow for cameras to focus in as little as 10 milliseconds.
