Nikon Announces Retro Z fc Mirrorless Camera And New Z Lenses

Image
Nikon Z fc You might remember Nikon’s Df retro-styled DSLR released in 2013. Today Nikon has introduced a new take on that classic design for its mirrorless Z system. The 20.9-megapixel Nikon Z fc is a DX-format (APS-sensor) camera that inherits its vintage looks from the iconic Nikon FM2 film SLR, but jumps into the future with 4K video, Eye-Detection AF and a Vari-Angle touchscreen LCD. The Nikon Z fc features a Vari-Angle touchscreen LCD that can swivel for selfies. In keeping with the retro design, the camera features mechanical dial controls on the top panel to adjust shooting modes, ISO, shutter speed and exposure compensation values directly. The overall package is slim and lightweight, and underneath the exterior is a magnesium alloy frame and weather sealing. Though the Z fc is not positioned as one of Nikon’s top tier models in terms of performance, it can capture a respectable 11 frames per second at full resolution when shooting in continuous mode. Mechanical dia...

Canon Introduces RF14-35mm F4 L IS USM Wide Zoom For EOS R

Image
Canon today debuted a new wide zoom for its EOS R full-frame mirrorless cameras, the RF14-35mm F4 L IS USM . Priced at $1,699 with expected availability in August, the lens is a more affordable and compact alternative to the faster RF15-35mm F2.8 L IS USM which retails for $2,299. Canon RF14-35mm F4 L IS USM Comparing the two wide zooms, the new zoom is lighter by more than half a pound, and has a closer minimum focusing distance of 7.9 inches (11 inches for the 15-35mm F2.8). The new lens also has slightly better image stabilization with up to 5.5 stops of correction from the built-in optical stabilizer (versus 5 stops with the 15-35mm F2.8) and up to 7 stops with compatible cameras via what Canon calls Coordinated IS. Both lenses are designated as Canon’s premium L-series optics, so the key advantage of the more expensive zoom is its faster maximum aperture. The RF14-35mm F4 L IS USM is threaded to accept 77mm screw-in filters, noteworthy for a lens with a focal length as wide a...

Capture The Picture In The Picture

Image
What’s a “big glass” landscape? What is your “go-to” lens to photograph scenics? Are you sure you have a polarizer for your 400mm lens? Wait—in some way these three sentences imply one should use a telephoto lens to make scenics! Yes—it goes against the norm to photograph a scenic with a wide angle, but just because everyone else uses a wide angle all of the time, there’s no reason to follow the flock. Somewhere along the line while you were growing up, I’m sure you heard your parents state, “If all your friends jumped off the Brooklyn Bridge, would you follow them?” (Or something to that effect.) With this in mind, stay alive and attach a 200mm or longer lens to your camera and make some scenics.  Camera Technique Telephoto lenses bring subjects closer since the angle of view is narrower and also magnified. Because the subject size gets magnified, this necessitates a critical camera-handling technique. It’s essential you use a sturdy tripod to acquire a sharp image. The long...
