Lightroom - Masking values for Pentax lenses
If you use the Lightroom sharpen presets, you will have noted that on the 'landscape' version, masking is set to '0'. Martin Evening's books only skirt over this (more space to images than text) and as a result I've never done anything with this slider, leaving it at '0'. However, after latching onto a threat in the Flickr Lightroom group, I've been educated a bit more on this and come up with starting values for my most recently used lenses. As follows:
DA* 16-50mm 75
DA* 50-135mm 85
DA* 60-250mm 85
FA 31mm Ltd 85 (75 for slides)
FA 77mm Ltd 85 (75 for slides)
FA 24-90mm 70 (+/- 5) for slides, 85 for mono film
These seem to be almost universal - I check most using by moving the slider whilst the Alt key is depressed and make little or no further adjustments. Been applied with images taken with my K3, K5, K5II, K5IIs and K7.
It makes a small but imperceptible difference at the time you make the adjustment but when it is viewed on screen after uploading to the likes of Flickr, it makes the image sharper, so worth the effort.

Depends on the volume you are loading at any given time I guess. I came back with 2800 raw images from Peru, so doing a bulk import with landscape sharpening, lens correction enabled and sync'd basic metadata is kinda useful. My work flow isn't all Lightroom - everything goes through Faststone Image Viewer first where it's assigned an image reference (I use Camera-DDMMYY-XXX as you may have spotted) - it's more versatile than Lightroom as you can use what ever combinations you want, then put into a meaningful folder (eg. 'Peru - Lima') ready for importing into Lightroom.
