Sinarback eXact

Sinar Photography is pleased to announce its latest development… … the new Sinarback eXact. Featuring new and truly ground breaking features, the enhanced and recently designed Sinarback eXact takes digital back features to an entirely new level — whilst maintaining Sinar’s uncompromising standards for quality and long-lasting tools for the production of outstanding and highest-quality professional digital images.
From 12MP to 192 MP in one Back.

The Sinarback eXact features multiple shooting modes, as per the table below…
As you can see, there are two XL modes where the back shoots with an effective 192 MP sensor. There’s the XL 4-shot mode, which provides 192 MP ‘single-shot quality’, however, there’s also the XL 16- shot mode, which samples real colours from the subject for each half-pixel step in both directions.
And it’s this method, which provides un-interpolated colour sampling for cleaner more accurate colours with greater contour sharpness unmatched by any other device. The new Sinarback eXact sets new benchmarks for both image-quality
and the integrity of your data! Naturally, the Sinarback eXact ideally suits applications where larger file sizes and/or highest quality/colour-accuracy is necessary for the job at hand…but wait, there’s more.

Sinarback eXact ‘all in one’
When biggest may not be best for your workflow…
In recent years, it’s fair to say there’s been an ever-increasing upward trend in the pixel density of MFD sensors. However, not only Sinar, but their clients too, have become acutely aware of the postproduction burden when producing images way too large for the purpose at hand.
