I am ´new´ to the forum, although I have been an avid reader / follower (/lurker?) of NR & NRF for about a year now. I have been out of photography for quite a few years now, relying on my camera phone and a Point&Shot for snapshots, ever since I put my old (analog SLR) camera on the shelf… and ´forgot´ about the joy of taking proper photographs soon after stopping using my old trusty SLR camera.
I’m looking to get back into proper photography again as a hobby, as soon as I’m able to foot the bill for new gear without receiving an angry phone-call from my bank manager.
Anyhow, with the ´introduction´ and formalities out of the way; let’s get down to the real intent of this post (my first on NRF). Start reading here for the tech stuff:
I’ve been following several discussions related to Nikon, and other manufacturers, camera frame-rate( fps), buffer size (or lack of appropriate buffer size, as it may be), and also discussions about different storage media (SD card, CF card, XQD card, etc. in all their variations & iterations).
To my mind; the number and speed of continuous shots is dependent on the system speed (throughput from camera sensor to storage media), and I see little-or-no discussions about the new standards that are available – like CFast and SDHC/SDXC UHS-ii (ver.4.00/4.10).
Now, in my (admittedly) limited knowledge & understanding of the data transfer flow from point A (sensor) to point B (storage medium) it appears that bottleneck is the system write speed of the storage cards in use today; where storage cards capable of higher sustained write speeds would solve (to some extent) the limitations in frames per second and number of frames in a continuous burst of pictures.
Looking at the specs of readily available storage technology; like SD UHS-ii which has a theoretical maximum throughput of 156/312MB pr. second (single/dual bus) and CFast which has a theoretical throughput of up to 600MB pr. second, I can’t help but wonder why camera manufacturers, especially those that have products with very high megapixel sensors like Nikon d800 & Sony A7R, haven’t embraced the latest technology and built this in to their products?
I would be interested in hearing the views on this from the people here on NRF, I know there is a lot of technically inclined people on here and the combined knowledge of NRF should make this an interesting thread IMHO.
So, what are your thoughts on (a) Nikon (and other manufacturers) incorporating the new, faster technology in their camera range(s), and (b) would improved write speeds to the storage medium be sufficient or would the current processing power of today’s cameras need to be improved to keep up with the data throughput. Also, (c) are there other bottlenecks in the system that (might) limit the speed of data throughput if we got cameras that supported storage medium capable of 300MB/sec. or faster?
I would love to hear your insights and opinions.
Oh,… and you’ll have to excuse any spelling mistakes and poor syntax because English isn’t my native language.
