The Digital Picture has recently posted their review on Canon EF 70-300mm f/4-5.6 IS USM and wrote:
” The Canon EF 70-300mm f/4-5.6 IS USM Lens has decent sharpness wide open and good sharpness when stopped down a stop or so. Corner sharpness is good even at full frame. The long end of the focal length continues to be the weakest performing over the range. Overall, sharpness is definitely improved from the 75-300 IS.
The Canon EF 70-300mm f/4-5.6 IS USM Lens exhibits barrel distortion (on a full frame body from 70mm to 120mm or so. Slight pincushion distortion is visible at 300mm. CA is very well controlled.
Light fall-off is quite noticeable wide open (f/5) at 200mm and improves slowly as the focal length is increased or decreased – or the lens is stopped down one stop. Light fall-off is still noticeable at 100mm f/4.5 and 300mm f/5.6. 1.3x and 1.6x FOVCF body users will avoid most of this issue. “

Quesabesde.com has just recently published an interesting interview with Carlos Ormazabal, Professional Product Manager of Nikon’s Spanish importer Finicon. One of the interview questions was discussing Nikon’s decision on choosing CCD for their Nikon D200 instead of CMOS, which Nikon has used it for the D2x.
“The D200 incorporates a CCD, but the D2X, the most professional of the make, uses a CMOS.
Nikon Imaging.com has recently published the new Nikkor 18-200mm page with its main features, specifications, MTF chart and lens construction. The page also has sample photos of Nikon 18-200mm shot with Nikon D200 @ 95mm, 1/8 secs, f/5.3, ISO100

Ken Rockwell has just posted his test review on the new Nikon D200, a DSLR camera with 10.2 megapixels, 5frames per second, 2.5″ LCD, and 11 AF areas. He wrote:
“Ergonomics: Superb! You really have to pick up and try the D200 to appreciate it. It’s even better than my beloved D70 since the ISO, WB and QUALITY controls have been moved to their own dedicated buttons. The D70, D70s and D50 share these record functions with playback function buttons, so the older cameras required you to tap the shutter button to get the camera back to the shooting mode before hitting them, otherwise you’d tweak a playback function by accident instead of your ISO. The D200 is brilliant!”
Tom has recently posted his test on the new Canon EF 70-300mm IS VS Canon EF 200mm on Canon EOS 350D. He commented:
“All 100% crops, only the tree bark was sharpened. I concluded that IS is amazing! I also concluded I need to check my prime for front focusing, although most of the problem with it is too slow shutter speeds with no IS.
The 70-300-IS appears to be a very nice lens – although noisy focus, and hunts a lot with the TC on it. If I find my prime is focusing correctly, it’s going to be sold!”
Scientist from Stanford University invents “Fourier Slice Photography” and “Light Field Photography”. It gives the ability to focus an out-of-focus shot afterwards.
The article points out that especially microscopy and medicine are fascinated by its potentials. Taking pictures of cells and tissue and then gradually focussing in different depths. By focussing in increments you can even create a small “film” that allows you to travel inside the picture.
Terry has written good basic tutorial on portrait lighting. The examples in her website were featured in The Complete Idiot’s Guide to Portrait Photography by Kathleen Tracy
Here’s my favorite lighting:
Rembrandt Lighting: “Still further left around Kiki, until a triangular patch of light remains on the leading cheek, is reminiscent of many of Rembrandt’s portrait paintings. As in butterfly lighting, the light needs to be fairly high — like Rembrandt’s studio skylight.”
LuminousLandscape recently posted their review on Panasonic DMC-LX1, a 8.4 megapixels camera with CCD chip, RAW support, true native 16.9 wide aspect ratio sensor, and an optical image stabilization. In conclusion they wrote:
“I really like the Panasonic LX-1. To have a shirt-pocket-sized camera with a high quality Leica lens, optical image stabilization, wide-aspect ratio 8.4MP chip, and decent manual handling, is a pleasure. Anyone coming from a DSLR will find that the shooting is slower, and the need to use the LCD for composition and focusing less then ideal (though typical of digicams). But then there aren’t that many DSLRs with 4:1 zoom lenses that will fit in a shirt pocket, so the argument is moot.
If you’re looking for a serious camera of this size, that requires you to expend some additional effort in post processing, yet rewards with portfolio grade image quality, the Panasonic LX-1will not disappoint.”
