Photographer Benjamin Von Wong was taking a tour of Nikon Professional Services facilities recently when he had an idea: with so much Nikon gear around, why not try making music with the cameras? After all, it’s not often that you have tens of thousands of dollars in gear at your disposal to create something fun. The video above is what resulted.
After reading the great reviews of the Fuji X100S, I decided to take the leap and buy one. I’ve been getting more interested in street photography lately, and this camera seemed like a good fit. Plus, it’s supposed to sync at all shutter speeds, which is great for flash photography outside in bright sun. David Hobby and Zack Arias both have nice in-depth reviews.
But, things are rarely perfect. It turns out that the X100S can’t sync at f/2 unless you’re at around 1/1000 or slower on the shutter. Nice, but still, I was curious why that is. So I decided to run some tests to figure it out.
If you’ve ever shot with a Leica M rangefinder, you probably know how effective the camera can be for stealthy shooting. After all, there’s no mirror that needs to swing out of the way like there is in a DSLR, so the main sound you’ll hear is the soft click of the shutter curtain flapping open to expose the film or sensor.
It’s not just Leica aficionados that appreciate the silent shutter: did you know that the Leica M is held as the standard for silent photography in courtrooms across the United States?
It’s not uncommon for digital cameras to have burst modes as fast as 10 frames per second these days — especially in mirrorless and pellicle mirror cameras — but do you think you have a good understanding of just how fast 10FPS is? If not, check out this video by YouTube user krnabrnydziobak, who pointed a Phantom Miro eX2 at a Nikon D4 to see what 10FPS looks like when captured at a staggering 1920FPS.
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.
