Title: The S90 as a 26mm camera ?!
Post by: thierrylegros396 on December 02, 2009, 09:30:23 am

Yes, if you process the raw file in Lightroom 2.5 (not 2.6 RC) you can have a wider scene than the Canon 28mm rating.

Save it and open it in Photoshop CS2 or later.

Use the Distort\Lens correction filter and crop it as wide as possible.

And the resulting file is wider than the Camera JPEG !

Have a Nice Day.

Cool feature - I assume this is because the in-camera JPEG does lens correction.

You can also zoom quite a bit further than the lens allows, but you might lose some megapixels doing that

Some pictures.

Out Of Lightroom.   Img_227
After Freeware "Lens Correction 1.0" filter.   Img_227-LC1
Out Of DPP.   Img_227-DPP
Test Set Up
After "Lens Correction" Photoshop Filter.   Img_227-PhotoshopLC

So if you keep the 4/3 format you have a 26.5mm lens equivalent.
But if accept 16/9 format you have a truth 26mm equivalent.

Have a Nice Day !

But the S90 is not a real 105mm tele !

Slightly shorter, about 100mm.
