A few times now, I've PM'ed people nad they've kept my identity quiet in public. Although unnecessary, I really appreciate that members of this forum are so thoughful of others.
I haven't taken part in this discussion yet because, to my shame, I haven't taken out the Sears lens I bought last week! Seriously - it's hard to find a good brick wall around here! (jk)
I did, however go backpacking in Yosemite and played with my DA40, FA77 and my Sigma10-20.
I got ripped off on my Sears 135 so maybe I'm just bitter. But, apart from a little brassing and scuffs, the lens is clean. The aperture clicks through quite nicely. For the few shots I took, I just didn't find it performed as well as I had hoped, especially in comparison to the 55mm f1.4 Sears I have. It didn't seem as sharp or have as clean a color rendition as my SMC Takumar 135. One thing I do appreciate about it though, is that the bokeh is much nicer than the Tak.
After looking at all these great pictures, I'm thinking I'll have to take it out and give it a proper try! Thanks to everybody who contributed and showed me what this lens can do!!!
