Tamron’s New All-In-One Zooms
Last evening, Tamron announced two new all-in-one SLR lenses, one full frame and one for APS-C cameras. The APS-C model is the Tamron 16-300mm f/3.5-6.3 Di II VC PZD Macro, which covers an equivalent 35mm zoom range of approximately 24-450mm, which is pretty amazing. As with all “all-in-one” zooms, though, we should expect some serious compromises in image quality, and of course, the relatively small maximum aperture at the telephoto end of the zoom (f/6.3) will be problematic in low light, and for those seeking shallow depth of field. The full-frame model is the Tamron 28-300 F/3.5-6.3 Di VC PZD, with no “Macro” designation. Both lenses make use of Tamron’s “Vibration Compensation” technology, which generally offers around 3 stops worth of image stabilization. It is worth noting that despite its designation, the close-focusing 16-300mm lens is not a true 1:1 macro; the best ratio it can achieve is about 1:3 1 With a a 1:1 macro, the image projected by the lens onto the sensor is exactly the same size as the object itself, whereas with a 1:3 ratio, the image size on the sensor is about 30% of the size of the real object. .
On the positive side, these lenses are very lightweight and incredibly convenient; you can easily carry a single lens to cover any focal length that you may need… particularly with APS-C model. On the downside, I expect the image quality to be passable at best, except in the center of the frame, where it is usually fine. Away from the center, the image quality on the lens’s predecessor2 The Tamron 18-270mm is pretty miserable, optically. is best described as “crappy”, and distortion is quite bad, so I am not optimistic about these lenses.

The Panasonic Lumix GH4
If you’re a micro-4/3rds shooter, the new Panasonic Lumix GH4 is a very exciting new camera. Perhaps the most important new feature is the ability to shoot professional-level 4K video, either at 24 fps
4096×2160 or 3840×2160 30p/24p, and with an option of two video formats. Beyond the camera’s expanded video capabilities, the camera has a durable shutter and magnesium body, both intended for professional use.
An optional pedestal unit is available for the GH4 that provides professional standard audio and video outputs with timecodes, and other controls.
