I own this lens since +/- 1 year and am very happy with it !
Fast, sharp, little vignetting ....
A very good fast "normal" lens on µ4/3

Here's a few examples I shot over time :

Those are all very nice pictures, thanks for sharing them. From the ones I tried, I think this little lens is the best value in 25 mm c-mounts (considering the prices that older ones go for...). I still sold mine because it is a little small for my large fingers - and I still have a few others in that length. But I keep regretting that when I see nice pictures like these here...

Does anyone know what kind of front cap I need for this lens or where I can get one?

You will need a 27mm lens cap - just search for one on Amazon. The first result will get you the Sunpak one, which was what I got. About $5...

I like this lens but have not been using it much. I actually like the circular bokeh and vignetting.

I'm actually having a lot of fun with mine. Looks out of proportion on my camera cause the TV lenses are so thin.
