Back to the Basics

The time was 2007, and CIPA (the Camera & Imaging Products Association, representing Canon, Nikon, Sony, Olympus, Kodak, Casio, Panasonic, Sigma, Hoya, and Fuji) showed that the score was thus:

Digital Cameras: 6,926,337

Film Cameras: 720,475

Through November last year, CIPA reported 11,199,175 digital cameras shipped. It’s pretty hard to argue, digital has won. But, even with the plethora of Nikon digital SLR cameras and Canon Powershot digital cameras and Sony digital cameras and blah blah blah out there, there’re a few things about photography that haven’t changed. Not as a result of image stabilization, nothing to do whatsoever with megapixels and ISO, and they don’t care whether you’re using a point-and-shoot or a DSLR.

They’re the elements and principles of design and composition.

Now, I’m sure Chuck and Jody at the least are intimately familiar with these, but here’s the shakedown for those wondering how design matters to their photography.

Design, as an art field, is the purposeful application of art as a form of communication. It uses, as its foundation, a handful of basic principles that are derived from visual Gestalt theory and human psychology. In short, these points are the underlying points for all visual arts, and that definitely includes photography.

There are, typically, seven “elements” of design:

Mirror Lenses, Apparently Not Dead

Sigma 200-500mm f2.8It’s been a series of odd coincidences around here lately. First off, Nick was taking an order for one of the more exotic of Canon lenses, the 800mm f5.6, so we were talking about exotic lenses in general and the big giants, like the Sigma 200-500 f/2.8 (a piddling 34.6 lbs for over 2 feet of lens. It needs its own battery. No, really) and my favorite big honking lens of all time, the Canon 5200mm f14 (pictures and a copy of the brochure page here, here, and here). Supposedly it had a working range of 18-32 miles and came with spotting scopes. Nice. This sucker reports to have been a very pocketable 220 lbs and 75.6″ long. Now, a lens taller than most adult men might sound massive, but if you stop to do some quick math and figure out that a 5200mm lens should be around 17 feet long, you might not find 75.6″ so bad.

It was a mirror lens, using mirrors in addition to glass elements to ‘fold’ light inside the lens, by first sending it to the back of the lens, then back up to a small mirror in the middle of the front element, and then finally sending it back to the sensor.

Then, the day after that, Jody was surprised to hear new announcements for mirror lenses (which have no aperture controls, you get one fixed aperture and need ND filters past that).

500mm f8 ReflexThen, today, I was reviewing the current Sony instant rebates, and saw the 500mm f8 Reflex sitting down in our Sony lenses. Apparently, if you buy Sony Alpha cameras you’ll find yourself in the unique position of having an available autofocus mirror lens, giving a fieldof view equivalent to a lens three times longer than it actually is.

Will it rival that $11,000 Canon for quality? No, but hey, for under $700 bucks and for it’s tiny size (well, compared to optically formulated 500′s), it’s going to be hard to beat. Don’t forget on any Alpha other than the A900 you’ll have a 1.5x crop making it a 750mm lens which is only about 5″ long.



Coming Attractions

Tamron 18-270VC imageTamron, long a leader in lens design and technologies announced an astounding 15x range zoom 18-270mm lens in development on July 30th. Yesterday our Tamron lens rep was here at Roberts Imaging with a little more news. The first 18-270 lenses shipping will be for the Nikon DSLR bodies, including the D40 and D60 series bodies. That’s right the AF 18-270mm Di II VC lens will also carry the BIM designation, so it will mount on all Nikon Digital Cameras. (Note: the full frame sensor cameras will not reduce the file size and coverage area as they do Nikon’s DX lenses, and  Tamron does not recommend their use. If used the resulting image will have to be cropped to eliminate vignetting).
Tamron’s Canon EF mount lenses will follow shortly after the Nikon’s and don’t be surprised to see the Sony/Minolta mount soon too.
If you are unfamiliar with the vernacular of the lens world  I will  give you a brief  jargon translation.
DSLR: Digital Single Lens Reflex. A camera with a mirror box and prism for viewing the image through an eyepiece (or now on live view); the mirror pivots (reflexes) out of the way allowing the light path to reach the sensor. AF: Auto Focus; just like it sounds the lens and camera can focus automatically (there is always the option to manually override if desired).
Di II: This is Tamron’s designation for a lens designed to work with the smaller APS-C sized digital sensors, some higher end DSLR’s will have a full size sensor the same dimensions as a 35mm frame of film (you remember film, right?).
VC:  Vibration Compensation; built in stabilization features that help reduce user shake,allowing sharper photos in challenging conditions. Nikon Lenses and Canon lenses offer their own version on some of their lenses VR (Vibration Reduction) is Nikon’s terminology, and IS (Image Stabilizaition) is Canon’s. Remember: vibration reduction, compensation, control or stabilization  reduces but does not always eliminate the need for a camera tripod.
BIM: (Built-In Motor) a motor on-board the lens instead of a mechanical connection to the camera body. Built-In motors are nothing new, Canon Lenses have been equipped with internal motors since the first EOS lenses. Nikon came on board several years ago as well with their AF-S series of lenses. Now Third party lens manufacturers like Tamron, Sigma and Tokina to name just a few are building the more efficient internal motors in some of their offerings too.
With new longer range lenses cropping up all the time the options for the casual photographer are much greater. A lens with a 15x zoom would be an all-in-one solution for a lot of users. We don’t know the delivery dates yet but you can pre-order this lens on-line or you can contact me at 800-726-5544 or [email protected]
