I'm still formulating my idea, but unless your cropping I don't think its an 85 as flower/bee shot is too close-focused for an 85, though the content of the shots on average seem to accomodate the field of view.
Something that close focuses, probably to at least 1:2 so that rules out a lot, though that daisy flower you show is reminicent of the 50-135 bokeh-wise based on your previous samples.
If its something you keep coming back to, its probably small enough to pack around and easier to use without an adapter. This also rules out a lot.
This leaves only 3 - DA35, Viv 105 & Sigma70. You just got the Sigma so that leaves two.
Bike shot looks tele to me, around 100mm.
Its the Viv105.
EDIT, and hey, it looks real nice the way you wield it
EDIT EDIT - hey, you just mentioned in another thread its an 85... you cheated! haha.
