I don't own a K-S1 but was wondering if it has the capability to convert a RAW shot into a TIFF in camera?

[Steve.Ledger]

I don't know of any camera that can save to TIFF internally. Why on earth would you want to do that anyway?

[Not a Number]

DNG is based on the TIFF-EP specification and is supposed to be compatible with the TIFF-EP standard.

There are many publishers that require TIFF. It may be easier to just shoot in TIFF or DNG when a camera has that option.

There are many publishers that require TIFF.

It is common, because the publisher only has to deal with different compression algorithms, not completely different file formats like proprietary RAW formats. But DNG files contain much more metadata than TIFF files. The publisher doesn't care about the lens you used, or exposure compensation, in fact doesn't want to have to do any processing on your images. TIFF files (and DNG and the other RAW formats) are lossless, unlike JPEG files, which means that if you resize a TIFF file you don't lose data like you will when you resize a JPEG file.

It may be easier to just shoot in TIFF or DNG when a camera has that option.

I don't know of any cameras that let you save images as TIFF, you would lose as much metadata as saving them as JPEG, and you would still be left with very large files. Many cameras let you save images as DNG or the camera manufacturer's proprietary RAW format, but DNG has the advantage of keeping all metadata in the same file as the image data, making file transfers much less problematic; and DNG is a versatile enough format that any software that reads the file can ignore any metadata it doesn't know how to handle.

Your images should only be converted to TIFF after you have done your post-processing, or at least let the RAW convertor software you are using make adjustments based on the camera model, lens model, etc.
