When Fujifilm announced its latest wave of X-Series cameras earlier this year, the company stated that the big area they’re focusing on is “speed”. The new X20 and X100s feature extremely speedy autofocus, burst speed, and startup time. The ‘s’ in X100s may officially stand for “speed,” but it could just as well stand for “silent” or “stealth”. Both cameras feature extremely silent shutters that won’t attract attention while you’re snapping away.

When it comes to figuring out our car’s life expectancy, we’ve come to expect a little bit of community involvement. Sure, the car company will tell you that your truck is supposed to last X-number of miles, but if the majority of real owners online disagree, we tend to side with them. But why stop at your car? Why not see what users are reporting about your camera’s life expectancy?
People who spend a lot of time on their feet have products like Dr. Scholl’s gel inserts to help cushion their feet and absorb the shock of walking. Likewise, photographers who press the shutter button so much that they fatigue their index finger now have a similar product as well: the Custom SLR ProDot. It’s a patent-pending dot add-on for your camera’s shutter button that supposedly helps reduce camera shake and finger fatigue.
Needing a way to test the speed of memory cards, Jaroslav of Crazy Lab realized that camera shutter sounds can do the trick. By recording the sound of his Canon 600D snapping away in continuous burst mode and then viewing them audio file, he was able to visualize the card’s speed and compare them against each other. He also learned some things about burst speed and ISO/format:
As you can see, the burst length is getting shorter with rising ISO. The time camera needs to write the buffer to the card is also significantly grown. The reason is the noise. On higher ISO settings we getting more noise in picture and noisy pictures are not good for compression. The RAW-File size (black picture shouted with closed lens cap) varies from 19MB @ ISO100 to 32MB @ ISO12800.
Also interesting is the comparsion of burst speed shooting in RAW versus JPEG. While the burst length with JPEG files is virtually infinite (with fast sd-card), the burst speed is slightly lower.
You don’t need anything fancy to do this experiement: Jaroslav used a webcam mic and the free audio program Audacity.
Measuring the performance of DSLR cameras [Crazy Lab]
If you think 14fps on a high end DSLR is fast, check out this video by Mike’s Electric Stuff. In it, he does an extreme teardown of a cheap Panasonic Lumix compact camera and spends 30 minutes exploring and explaining the various components. At about 18 minutes in, he hooks up a signal generator to the shutter mechanism to see how fast the shutter can flap. He’s able to take it up to around 70 flaps per second before the shutter begins to stutter. The limiting factor in FPS isn’t the mechanical components of a camera, but how fast the sensor and memory card can capture and store data.
Thanks for sending in the tip, StuartB!
Here’s a camera shop promo that features the Nikon D4 filmed with a Phantom Gold high speed camera. It shows what the camera’s 11fps shutter and iris mechanisms look like when captured at 1000 frames per second.
Destin of Smarter Every Day wanted to show how a DSLR shutter works, so he pointed a Phantom high speed camera at a Canon 60D and made this slow motion video showing the magic that happens every time you press the shutter.
To keep itself lean and focused, Google is planning to do some spring cleaning and shut down a number of non-critical projects and services that don’t attract enough attention to keep alive. One of the services marked for termination is Picnik, the online photo editor that Google acquired back in 2010. The service will remain online until April 19, after which the team will be folded into the Google+ team.
Shutterlog is an interesting YouTube channel started earlier this year by Mijonju and Cameron Lew that collects user-submitted videos of people taking a picture with their favorite camera. After receiving and sharing over 100 videos, they decided to take some of the shutter click clips and remix them into a beat. It’s like a simpler version of Lv Sisi’s Digital Analogue.
Here’s an interesting glimpse into what a DSLR’s aperture blades and shutter curtain look like in super slow motion. Specifically, it’s a Nikon D3 shooting at 11 frames per second with 1/4000 shutter speed and f/16, all captured at 5,000 frames per second. What’s amazing is that the shutter curtain moves so quickly that you can’t see the sensor at all, even at 5000fps!
