Sony's new concept "interchangeable lens compact camera" for PMA 2010 this week may be catching glances for its small body size and possible indication that the company are planning a jump into the Micro Four Thirds market, but according to Amateur Photographer the really interesting part might be the lens mount itself. They were closely watching Masashi Imamura, Sony's President of Personal Imaging and Sound Business Group at the company's press launch, and he removed the re-attached the concept Alpha DSLR's lens with none of the usual twisting.
There is no doubt that 3D technology is booming today with lots of new 3D films hitting the theater. The massive success of Avatar has led more people to check out a 3D film and more and more theaters around the country are looking to add 3D capability.
As promised, Pentax have unleashed their latest DSLR, the 14.6-megapixel K-7. Pairing the new CMOS with the PRIME II imaging engine, the K-7 is also the first of the company's DSLRs to support high-definition video recording. Where many rivals top out at 720p, the Pentax can climb all the way to 1,536 x 1,024 at 30fps (3:2 aspect; 16:9 720p is also supported), and has an HDMI output for easy viewing.

NTT have developed a variable focus lens that they claim is 1,000x faster than existing technology. The lens is based on KTN (potassium tantalate niobate), an "electro-optic crystal" the refractive indices of which varies depending on how much voltage is applied across its surface. By adjusting the voltage, the focal length varies.
Typical macro lenses -- normal to telephoto focus length range – usually have maximum aperture at F2.8 or slower, with the exception of Olympus Zuiko Digital 50mm F2.0 ( Four Thirds lens) at one stop faster. Tamron has today announced the development of SP AF 60mm ƒ/2 Di II LD (IF) Macro 1:1. Like the Olympus, it’s a digitally optimized Macro lens featuring a bright maximum aperture of ƒ/2.0.
Having owned four 1.4x teleconverters for my birding outfit, I was excited to see a new candidate at PMA 2009. From previous report, we spotted a 3rd party battery grip for 5D Mark II at Meike booth, as well as a new a 1.4x TC available for both Nikon and Canon mounts. The design is closely resembling the Tamron SP or the kenko standard 1.4x TC; it doesn’t has a front element that’s sticking out from the mounting flange nor o-rings for weather seal, but definitely has slight edges in built quality.
