Hiking time: 170 minutes and 45.69 seconds, or 2 hours and 50 minutes. East Butte Natural Trail entrance at 33rd St to Hill 1000 summit, way trail parallel to south unpaved Blaine Ave to south unpaved Blaine Avenue to intersection with Gresham Butte Saddle Trail straight ahead to north unpaved Blaine Avenue to summit of Walters Hill, back down north unpaved Blaine Avenue to intersection with Gresham Butte Saddle Trail, to south unpaved Blain Avenue to summit of Hill 1000 to right on East Butte Nature Trail to car. Very satisfying hike. Felt ecstatic driving back home.

Took 101 photos with two lenses: super wide angle shots with the Panasonic 7-14mm and telephoto shots with the Olympus 40-150mm, with nothing in between. 49 made the cut.

The only reason I could use the Panasonic lens was because it was completely and evenly overcast with no hot spots in the sky, which invariably produce purple flare in images with this lens when used on Olympus OMD bodies. This is why I'm going to sell this lens (and all my redundant lenses) to obtain funding for the Olympus 7-14mm lens which is coming out next year.

I really enjoy using the 7-14mm lens when there is no purple flare, but when there is this purple flare, it is maddening and hateful. This lens also has tons of chromatic aberration, which I eliminate with Lightroom, but it adds 15 seconds of post-processing to every blasted image. There is virtually no chromatic aberration in the dirt cheap but superb Olympus 40-150mm. With all these defects in the Panasonic 7-14mm, one positive thing that can be said about it is that it is an extremely sharp lens. Let's hope that the Olympus competitor is just as sharp.
