3D Four Letter Words: Robert Indiana’s LOVE Sculptures

15 Feb

[ By Steve in Art & Sculpture & Craft. ]

Looking for love in all the right places? Replicas of artist Robert Indiana’s iconic Pop Art “LOVE” sculpture have spread to the 4 corners of the globe.

Robert Indiana (formerly Robert Clark) first expressed the essential iconography of “LOVE” in 1958 but it wasn’t until 1964 that the image garnered wide public notice, via a Christmas card commissioned by the Metropolitan Museum of Art. One of the first three-dimensional LOVE sculptures has stood, since 1970, in front of the Indianapolis Museum of Art.

Like many metal artworks designed to stand out in the open, the IMA’s LOVE sculpture is made from Cor-ten steel, an alloy that weathers to a rich, slightly iridescent, purplish-brown patina after years of seasonal changes. The sculpture measures 12′ x 12′ x 6′ and has recently undergone a structural and aesthetic restoration.

I LOVE New York

There are currently around 50 LOVE sculptures installed in public and private spaces worldwide. Some are better-known than others, mainly due to their proximity to pedestrian traffic. One of the first NYC LOVE sculptures was installed at 59th Street and 5th Avenue in 1971, while perhaps the most prominent NYC LOVE sculpture stands at the corner of 6th Avenue and 55th Street in Manhattan. Kudos to Flickr users Chee917 and Robert Wright (wrightrkuk), who snapped the sculpture in 2012.

LOVE Is Blue

Most of the world’s LOVE sculptures have red painted facades with blue or blue & green sides to match Indiana’s original MOMA card and popular USPS stamp. This isn’t a must, however, as Indiana famously neglected to properly copyright the work. This bright blue representation outside 1445 West Georgia Street in Vancouver, Canada (later moved) shares its blue & green color scheme with another LOVE sculpture located at the Park Mall in Singapore.

Reflections of LOVE

ZY Optics unveils new Lens Turbo adapters for Micro Four Thirds cameras

13 Jan

Chinese lens maker Zhongyi Optics has added M42, Canon FD and Minolta MD lens adapters to its second-generation Lens Turbo lineup for Micro Four Thirds cameras. Like Metabones’ Speedboosters, the adapters shorten the effective focal length, increasing the F-number by one stop and partially negating the crop factor. The 0.726x focal length reduction combines to give a net 1.45x focal length crop, rather than the 2x crop that you’d usually experience on a Micro Four Thirds camera.

These three adapters join ZY Optics’ existing Lens Turbo Version II adapters for Canon EF and Nikon G lenses. Among the adapters’ four optical elements is an extra-low dispersion element, and all three offer stainless steel mounts and metal bodies.

All three adapters are available directly from ZY Optics for $ 149 USD.

Panasonic adds Leica 100-400mm F4-6.3 tele-zoom to Micro Four Thirds lens lineup

09 Jan

$ (document).ready(function() { SampleGalleryV2({“targetContainerClass”:”sampleGalleryImageViewerContainer”,”galleryId”:”2215321511″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”startInCommentsView”:false,”isMobile”:false}) });

Panasonic is adding a high-end super telephoto zoom lens to the Micro Four Thirds lineup: the Leica DG Vario-Elmar 100-400mm F4-6.3 ASPH. This lens has the longest focal length of any MFT lens, and Panasonic promises fast autofocus thanks to its 240 fps AF drive speed.

This lens is equivalent to a whopping 200-800mm when attached to a Micro Four Thirds body and features much-needed ‘Power’ optical image stabilization to keep things steady. It has has one aspherical, one UED, and two ‘regular’ ED elements, as well as a nine-bladed circular aperture. The minimum focus distance is 1.3m, with a magnification of 0.25x. 

A cool feature of this lens is its compact tripod collar which rotates with the camera body, taking the buttons with it. The collar has a tripod screw mount built into it, into which a longer (included) ‘foot’ can be added if additional clearance is need. The zoom lock is built into the lens barrel, as is a small pull-out lens hood (a full-sized hood is available as an optional accessory). The 100-400mm is also sealed against dust and moisture.

The Leica DG Vario-Elmar 100-400 F4-6.3 will be available in early April at a price of $ 1799.99.


Press release:

Panasonic Launches LUMIX G 100-400mm Telephoto-Zoom, LEICA DG VARIO-ELMAR Lens

Las Vegas, NV (January 5, 2016) – Panasonic has today introduced a new telephoto lens for its LUMIX G range of Micro Four Thirds System cameras – the LEICA DG VARIO-ELMAR 100-400mm F4.0-6.3 ASPH. Telephoto-Zoom (H-RS100400) with Power Optical Image Stabilization (O.I.S.).

Small, light and highly durable, the latest addition to Panasonic’s range of interchangeable lenses is perfectly suited for photographing birds and other wildlife in all types of environments.

The lens is constructed of 20 elements in 13 groups and incorporates a number of aspherical and extra low dispersion elements to assure best quality and avoid flaring. The advanced construction of the new Telephoto-Zoom leads to highest quality standard earning the LEICA Logo for a LUMIX Lens once again.

Outstanding image quality and Telephoto-Zoom performance

Elegantly designed with a metallic black finish, the new 100mm-400mm LEICA DG VARIO-ELMAR lens from Panasonic provides superb image rendering across the entire zoom range. The lens’ 200-800mm focal length (35mm equivalent) and 0.5x Magnification capability provide highly detailed shots from distance, as well as stunning close up capability– ideal for subject matter regardless of shape and size.

In order to capture steady, vibration free images across the entire zoom range, the lens also incorporates Power O.I.S. to keep unwanted shaking under control and ensure pictures look crisp and clear. 

The 100mm-400mm lens is also suited to a variety of photographic styles – with nine diaphragm blades providing a circular aperture to produce a smooth and beautiful bokeh.
 
Smaller and lighter than other Telephoto-Zoom lenses

When compared with conventional super telephoto DSLR lenses, the latest addition the LUMIX G line up offers outstanding mobility – perfect if you’re travelling and don’t want to pack too much. Similarly, the lens also boasts a durable, gapless construction so you no longer have to worry about unwanted dust or light rain damaging your equipment.

In addition to the lens’ practical size and weight, a compact, two-part tripod mount has also been incorporated to enable faster conversion between landscape and portrait orientation. While conveniently and speedily turning to the 90° angle, the levers for Focus Limiting, Power O.I.S. and the manual focus switch remain right at your fingertips as they do not move when you turn the lens. 

The lens also incorporates an integrated, hide-away hood to help you capture that perfect shot, without having to worry about sun glare.

Stunning 4K video capability

Panasonic’s new LEICA Telephoto-Zoom lens is perfectly suited for 4K video recording with its construction assuring the best contrast and colors. Furthermore the Telephoto-Zoom incorporates Panasonic’s high speed and precise 240 fps AF-motor. Due to the modern design, filming can also be conducted silently, so you can get up close to the subject without drawing attention.

As well as high resolution video, the lens’ 4K capability also enables you to take photos like never before. Panasonic’s 4K Photo function – found on LUMIX G cameras including the LUMIX DMC-G7 – lets you extract an 8-megapixel still from 4K video (30fps) easily right on the camera’s screen with a simple fingertip touch.

Key features:

  • Longest focal length for Micro Four Thirds
  • Compatible with Dual Image Stabilization
  • 240fps AF Drive
