D600 review isn't that great (some aspects)

But when a laptop with new core i5/7 mobile processor gets gunked up with dust - as they all do, maybe yours get that way. mine certainly don't. i recently opened one of my laptops to swap a hard drive and there was no dust or gunk. it's 4 years old, which is plenty of time for that to happen. Oh sorry. I was assuming that for normal people, and forgot that there are some perfect people posting to this forum. |

You can't see where the dust actually collects when you change the HDD. |

I haven't found on like that you still cant see inside the fans. |

What brand of laptop is that? (So I can remember not to buy it!) I've had a couple dozen laptops over the years and worked on a great many more, and I can't remember even one where you had to take off the keyboard to replace the hard drive. (Memory modules, yes, but not the hard drive.) Bob |

It takes a lot longer for Bridge to assemble the viewing information, than the time for my D300 files. I anticipate even longer times when I start shooting 14 bit color depth. FWIW, this is resource monitor screenshot using the (cheap - probably about US$6-700 in the US?) laptop with 3612QM cpu, opening a 14 bit D800E lossless compressed raw file, then rotating (levelling tool), then applying some colour control points, applying some d-lighting (high quality), then some USM, then some noise reduction (high quality), then saving again as an *.nef file and closing Capture NX. http://i50.tinypic.com/qoxaw2.png Says little, except that the app makes use of additional CPUs. True, Case closed. but the CPU isn't "maxing out" for any extended period, and there's the RAM use chart as well. Dynamic CPU clock-speed monitor widgets don't seem to report ivybridge CPU properly, a basic monitor app from Intel, shows clock speed jump to about 2.8 GHz for brief instants when working on the D800 raw files, then drop back to idle at 1.2GHz. It seems happy to sit at 3GHz for 5 minutes or so while transcoding some video, but once the cooling system is full of dust over time... And what do you suppose that tells us, other that your computer is suboptimal (i.e. slower than it needs be) for the program in question? Now, do the same with a D300 or similar file and then we can compare. I have a Core 2 duo (T7500) here - it's "adequate" with D300 files. Let me rephrase that! "Now, do the same with a D300 ON THE SAME COMPUTER, DAMNIT, and then we can compare." CPU speed is the "bottleneck", and if that isn't adequate, more RAM, faster (ie SSD) drive, or physically separate HD for the NX cache isn't likely to make much difference. I don't know if CaptureNX can handle a GPU, but that would be the obvious next step. I don't know either. Find it out. I suppose there are some geek tools used by gamers etc to monitor GPU, VRAM etc. I think some of the new Macbook pros (and others?) even have a separate graphics card, but can use the intel on-chip graphics to save power, and the external GPU kicks in only when needed. Google: Nvidia Optimus. But does the GPU actually assist with raw conversion etc, or assist with displaying (zooming, viewing multiple layers etc) graphics for which that "number crunching" has already been done? That depends on the program. PeterN (above)reports that "It takes a lot longer for (Adobe) Bridge to assemble the viewing information, than the time for my D300 files". I've read similar comments elsewhere, that even with very fast machines, before D800 files can be (pre)viewed at 100%, there's a couple of seconds lag. With ViewNX, rendering D800 files is effectively instant - ie when clicking the image preview to bring up 1:1 pixel view on screen. I suspect that's an "issue" with Adobe bridge. You're comparing fresh water fish and sunrays, so that means nothing. Meanwhile, I played with a D600 and D800 yesterday (and a Canon 6d). RichA's bull**** making a big deal about build quality compromise and ergonomics is of course bull****. Tell news! -Wolfgang |
