Choosing a camera system has profound effects on many aspects of your
photo career that go far beyond mere differences in mega pixels or file format.
Every aspect of your craft, including the quality of your work, the fees you can
charge and the flexibility of assignments you enjoy, rests on your choice of a
camera system. Dual format cameras provide a perfect balance of film or digital
capture flexibility that no other camera system can equal.
Size Matters Bigger is indeed better! There is simply no
denying that as you increase your film or digital sensor size, so increases the
quality of your image. Larger film or sensors result in better color and tone,
less noise, and greater detail. The bigger format (6x4.5) is nearly 3x larger
than 35mm SLRs and 4x or more larger than most D-SLR cameras. The superior image
quality is visible not only to you but also to your client and ultimately those
who will view your images. In addition, the large viewfinder is an excellent
visual workspace for composing images.
Modular Design – Greater Versatility Dual format cameras
allow you to configure them to meet your own shooting styles or needs. You may
choose different viewfinders, film, instant or digital imaging backs. The
interchangeability of these image capture backs provides the flexibilty you need
to meet the demands of your clients. Today’s dual format camera systems offer
you the flexibilty to address your clients’ ever changing needs with one camera
system.

Film Format

Digital Format  |
6x7cm: An image area 4.5 times greater than 35mm, with a detailed
negative large enough to view with the naked eye. The “ideal format” based upon
the traditional 8x10 proportion, matching page layout and printing papers.
6x4.5cm: At 2.7 times larger than 35mm, the 645 provides a
dramatic increase in quality while allowing for a compact camera design that
rivals the size and handling of a 35mm SLR. |
|
Bigger is Better: Similar to film formats, larger sensors
offer higher Resolution, greater dynamic range, more color depth and bigger
pixels as compared to smaller sensors. |
Digital Ready As tomorrow’s professionals, today’s photo
students will be expected to know and understand digital imaging. Mamiya’s lens
selection and interchangeable backs make these cameras the perfect platforms for
the digital backs of today and tomorrow. If film is the capture media of choice,
then these dual format cameras offer large film formats that provide for perfect
scanning. More color, tone and resolution can be captured from film scanning
these large formats resulting in better quality images as compared to smaller
D-SLR cameras.
