    Nikon D3 at Amazon
    Nikon D700 at Amazon

    The D700 or the D3, which one should I get?

    Image quality wise there are no perceptual differences between the D700 and D3. There are four primary differences between the cameras: (1) length of life (2) processor speed (e.g., impacting frame rate) (3) size/ergonomics and (4) the D700 has an on-board flash.

    The D3 is more of a heavy-duty camera – it is more reliable and has a greater shutter life (150,000 vs. 300,000 actuations) so it will last a lot longer. I can see this as a big seller for pro-photographer, but for amateurs, like myself, probably not as much as we will probably upgrade to a new camera before the camera’s demise. Alongside this pro-advantage – the D3 has dual memory slots. But hey –

     us amateurs can get bigger cards – 32G cards are becoming quit reasonably priced.

    The D3 has a dual processor giving the D3 more power and speed –

     it can achieve a frame rate of up to 9 frames per second. The D700 achieves 5 fps with its single processor, but with the MB-D100 battery grip with AA batteries it offers up to 8 frames per second. The D3 has a slight edge as it goes to 9 fps but in practice this is not really noticeable. With the battery grip the D700 is bulkier, larger and heavier than the D3 and not as ergonomic – again ergonomics is a factor for heavy-duty hardcore shooters.

    Another advantage of the D3 is the 100% viewfinder coverage –

     the D700 only has 95% coverage.

    The D700 edges the D3 on having sensor cleaner and as a smaller & lighter travel camera, it is lighter on your wrist but the trade-off (without the battery grip) is focus acquisition and frame rate.

    In summary the choice boils down to a function of price versus wear, so for the price of one 2008 D3 ($4,540), you may get a 2008 D700 ($3,000 + $240 grip) and a 2010 D800 with newer technology – so the question is within that same time span do you want (need) the D3? But of-course, it is just something about having the best Nikon Camera – and that is of-course the D3 (or perhaps the upcoming the D3x).

    The D3 difference:

    • 300,000 actuations (150,000 for the D700)
    • Dual memory card slots (vs. single on the D700)
    • 100% viewfinder coverage (95% for the D700).
    • No build in flash.
    • Better ergonomics.
    • No sensor cleaner.
    • Choice of a 5:4 image aspect option (D3 only)
    • Better battery life.
    • Frame rate 9 fps (D3), 8 fps (D700 with a battery grip), 8 fps (D300 with a battery grip).
    • Price $4,540 (D3) vs. $3,000 (D700) vs. $1,625 (D300).
    • The MB-D100 battery grip is $240.00.
    • .20 seconds focus and shoot with the D3 (vs. .25 seconds for the D700).

    Photoshop CS4 at Amazon

    Adobe announced their new photo editing suite, CS4 at Photokina.

    The primary differences between Photoshop CS3 and CS4 are the access to tools (curves, layers, saturation and more) and masking out objects directly by clicking on an image’s pixels. When the dialog is launched it accounts for the selected pixels by setting default values and selection points.   There are at least three reasons to upgrade:

    • An Adjustment Panel to access tools more directly by a point and click interface. You access the panel by clicking on the the photo itself (as opposed to getting to tools from to the layer interface). For example while you click on the image, you can directly access the curves dialog and it defaults to a starter point (tone) that is the ‘darkness’ of the pixel that you clicked on the photo.
    • Mask Panel – Easy access to masking functions (selections, feather, etc), again by clicking on the image – makes it easy to to selectively mask out selected objects.
    • Transformation Interface –  resizing and skewing the image is more direct and more immediate.

    Coming out in November — and I want to try these babies out! I would like to couple the Sony body ($2,999) with the Zeiss 24-70 f/2.8 ($1,800).  I think a good match for the Canon will be either the 85 f/1.2L or the 24-70 f/2.8.

    Canon 5D II
    Canon EF 85mm f1.2L USM Mark II
    Canon 24-70/2.8L 

    Sony A900
    Zeiss Vario-Sonnar 24-70 f/2.8 ZA
    Zeiss Vario-Sonnar 135 f/1.8 

    Sony 70-200 f/2.8G SAL
    Zeiss 85 f/1.4 SAL

    But not sure what lenses I should rent for my comparison. Leaning towards the Zeiss 24-70 f/2.8 – it got fantastic reviews. I would like something that is comparable to my Nikon lenses. I have the Nikon 24-70 f/2.8, Nikon 70-200 f/2.8 and Nikon 85 f/1.4 for my Nikon comparison. Nikon really needs to update their prime lenses!  Hopefully we will see some more coming out next week at Photokina.  

    Sony A900:
    Pros:

    • Full frame 24.6 megapixel Exmor CMOS sensor.
    • In camera stabilization system that works in practice.
    • Dual Bionz image processors.
    • 3K price tag (which is reasonable for this level of camera)
    • Takes the world class Zeiss lenses.
    • 9-pt dual cross focus centers
    • 5 fps continuous shooting (for up to 13 RAW frames)
    • USB 2.0.

    Cons:

    • Heavy 2.07 pounds (939 g) (but lighter than the Nikon D700)
    • Wish there were more focus points.
    • Noise even at low ISO 200, above 200 it is bothersome ):
    • No flash

    Canon 5D II (available November, 2008)
    Pros:

    • 9 cross-haired AF points – AF system have a slight improvement over the old 5D.
    • 6 non-addressable assist focus points.
    • Live View.
    • 21.1 megapixels CMOS sensor (old 5D was 12.8 megapixels).
      • pixel pitch 6.4 µm (old 5D was 8.4 µm)
      • New RGB color filters with improved transmission rates.
      • Cleaner images.
      • DIGIC 4 processor.
      • Canon claims highest image quality of any EOS digital SLR released to date.
    • Movie mode.
    • $2,699

    Cons:

    • Slow frame rate of 3.9 frames/sec
    • No flash.

    Reviews across the web for the Sony A900:

    Quote that puts the cameras (Nikon D700, Canon 5D II and Sony A900) into a nice perspective – from Mike Tomkins and Shawn Barnett article over at imaging-resource [cite link here].

    “Each of the sub-$3,000 full-frame digital SLRs offers its own unique strength. The Nikon D700 may “only” be 12.1 megapixels, but it can fire off eight frames per second, and has some very impressive high-ISO performance. The Sony A900 offers astonishingly high resolution, at 24.6 megapixels, and yet still cranks out a respectable five frames per second. And the Canon 5D Mark II has very high resolution of 21.1 megapixels with the added benefit of HD movie capture. Unless you need high speed capture, and a 30fps HD movie is out of the question, the Canon 5D Mark II appears to offer the best of both of its competitors, with high resolution capture and what we expect to be very good high ISO performance. Your needs and your lens collection will help decide which way you lean; the big story is that for the first time you have a choice.

    Imagine, any day now we may make a leap in understanding the universe better.

    The CERN particle collider, the Large Hadron Collider (LHC), just had his first successful test in getting ready to smash particles.

    Particle colliders have been around for a while (at least since the eighties)- and we got our own colliders here in the US, e.g., Stanford’s SLAC (a linear collider) and there are some circular ones – not sure where they are located (but one I believe is Fermilab in Illinois).

    What is different about Hadron, in CERN, is that it can produce enough energy to potentially generate a Higgs boson (if it exist)– we don’t know whether it exists or not. It is a weightless particle, or a particle with no mass.

    The boson is necessary to explain a lot of theories in physics, for example you may know about gravity and you probably know about mass and energy (Einstein), this boson would unify the gap between gravity, mass and energy. Cool and exiting stuff!

    What about the danger?

    Some people think it is dangerous because it may create a miniature black hole, and some say it will decay while others say it will suck in other mass and grow and ultimately we all get sucked in. However, Stephen Hawkins, you may remember him from his special appearance on Star Trek, says that the particle collisions even greater than the one anticipated happens millions of times in the earth’s atmosphere so there is nothing to worry about.

    I also would like to add that Hawkins also placed a $100 bet that the experiment will not produce a boson.

    I enjoy Scott’s pedagogy – he has a flair of writing in a tone that is approachable to the novice but with a few nuggets for the more advance users. This book is in a nutshell Margulis secret weapon arsenal: (1) Curves, (2) Channel Blending, (3) Sharpening, (4) Highlight and Shadows, (5) Apply Image and the use of (6) LAB space but with a few additions, masking in “painting with light” and RAW. Here, Scott diverts from the Margulis philosophy of only making global edits; and diving into “RAW processing.”

    However, the story is re-told in the classical, engaging and always humorous Kelby voice making his books a joy to read and well worth the money. I hope what comes next is a joint adventure with the big three photoshop masters – Scott Kelby, Karen Eismann and Margulis in a narrative trialog.
