The Nikon D7000 does choke and get its memory buffer full when rapidly shooting series of shots using standard SDHC cards.

This can create an inability to take follow on shots while waiting for the Camera’s in Body Memory Buffer to clear.

SanDisk Speed Class UHS-1 SDHC memory cards, rated at 45MB/sec read/write, provide significant improvement in clearing the D7000 memory buffer more quickly thus allowing capture of follow on shots.

“UHS” is the acronym of Secure Digital Association’s SDHC (Secure Digital High-Capacity) “Ultra High Speed” standard.

There is a UHS-I and an even faster UHS-II speed standard.

Both of these UHS speed standards are faster standards than the prior slower Class 4, Class 6, and Class 10 speed standards.

Class 4 being the slowest of these standards and Class 6 and Class 10 being respectively faster and faster.

Having recently searched, compared and reviewed, I found that there is now an even faster rated SDHC card on the market than the SanDisk UHS-I, I again ran my speed tests.

Here we have results of running parallel testing comparisons of two different SDHC UHS-I speed class cards:

  • SanDisk Extreme Pro 32 GB, rated 45MB/sec Read and Write
    • versus
  • Delkin Elite 8 633x Secure Digital 8 GB, rated 95 MB/sec Read, 80MB/sec Write

in a Nikon D7000 DSLR body.

For similar sized memories, the Delkin currently (May, 2011) runs more than two times the price of the SanDisk product,  and the Delkin’s are rated almost twice as fast …, so what did we see?

Computers are an essential part of Digital Photography

Writing has taken a back seat as editing of a wedding I second shot, and issues with computer viruses have taken up a great deal of my on screen time the last two weeks.

Using a system which incorporates both an HP desktop, running Windows 7, and an HP laptop, running Vista, each system became in turn subject to insidious virus attacks.

Error codes?  Yeah, I had error codes… Continue reading Computers are an essential part of Digital Photography

Nikon D7000 Memory speed tests, SDHC Memory Cards: including Sandisk Extreme Pro UHS Speed Class 1 45MB/Sec and Several Popular Class 10 SDHC Cards

Sandisk Extreme Pro SDHC 45GB-Sec 8GBSo, the D7000 DX sensor format camera body has a hundred shot built in memory buffer, right?

Not exactly, this buffer size, in number of pictures depends on photo quality.

When shooting High Resolution RAW Nikon NEF images in 14 Bit depth, the D7000 can only story 10 shots in its built-in buffer.

What is the future of crop sensor and full frame ( 35mm x 24mm ) size sensor formats for digital technologies?

Will the full size sensors dominate the professional digital photography world for always, or will the crop sensors push them on out, much as 35mm film pushed out the large box cameras of years past?

Sure the large sensors currently have better signal to noise ratios.

What are the other larger sensor inherent advantages? Continue reading Full frame vs crop sensor what is the future for DSLR’s?

How does flash duration and freezing movement depend on the model, type and power output of your flash units?

This weekend shooting a jumping model into the sunset created images failed  in freezing motion.  Further, the heavy DOF (depth of field) of shooting at F22 rendered dust on the lens filter easily visible throughout the blue sky.

Motion Blur using Studio Flash and Dust visible on lens filters stopped down to F22 Tokina 11-16mm

Paul C. Buff Cyber Commander CyberSync Initial Set Up

Flash Menu Screen Cyber Commander
Flash Menu Screen Cyber Commander with All lights Selected

While the Cyber Commander CyberSync System is proving easy in use once configured, initial setup out of the box for me here in Phoenix with Paul C. Buff’s Flash Trigger Transmitter and Receivers was not at all intuitive.  Having read the instruction manual, I turned the unit on and was baffled.     

Needing to get the units ready for a glamour photo shoot, I called the factory.  Lucky for me, the very pleasant gurus on Buff’s technical support staff were patient, clear and quite helpful over several phone calls.  While a lengthy setup process the first time through, I have broken down the learning into a fairly long yet simple recipe format.    

Here is how you go about setting up the unit once you have installed batteries… Continue reading Paul C. Buff Cyber Commander CyberSync Initial Set Up

Cyber Commander Flash Trigger and CyberSync Flash Remote System by Paul C. Buff

Buff has been my primary lighting supplier for a while now.  Generally, I have been quite pleased with the Buff strobe’s performance and ease of use and most especially their excellent customer service.  For triggers, I had not gone the route of Pocket Wizards which many pros and studios use.  Instead, I used the Yongnuo CTR-301P with two receiver set up.   The Yongnuo’s, being so much cheaper, seemed worth a try.

While the 301P’s work great with fresh batteries, as the batteries get weaker, there’s no low battery indicator.  With weak batteries the units start misfiring sporadically.   While the batteries work for hours and hours and days of use, there is no way to tell if batteries in the trigger, the slave or both are the issue, or if and they will start to go…   Continue reading Cyber Commander Flash Trigger and CyberSync Flash Remote System by Paul C.
