Sears 135mm wide open

A fellow Pentaxian bought one of these and doesn't seem happy with it, so I promised I'd do a test with mine since I kind of like it. Considering these tend to go for next to nothing I am pleased. Wide open you can see a little 'glow' in the shots.

Wide open at 2.8:


100% crop:


For comparison, 40/2.8 Limited at 5.6, 100% crop:

I've got one too, and even though it can be hard work sometimes, when it's 'bang on' I have got some amazing shots with it


And it cost me £7

Can't complain!

I have a "whooping" $40 invested in 3 Sears lenses (had 4): 135mm f2.8 K "A", m42 135mm f2.8 EE and m42 50mm f1.4 EE.

I find that all three are sharp wide open, m42 are more so. I will post few pics later.

Regards,
D

I have a Sears 135 2.8 it cost US$10 and it's completely disassembled because the aperture blades are so sticky that they they don't move at all. I have no plans to reassemble since I have the Takumar 135, which is nice and snappy.

I also just got the JCPenny 135 (off Ebay) because it has a macro mode (1:4 at max magnification), but that one has sticky blades as well (same maker?). As it shoots only at 2.8 its got a lot of glow at 1:4 macro. Pretty low quality overall. I do want to try to disassemble this lens and repair it. A good winter project.

I have 2 copies of the Sears 135mm f2.8 with the so-called macro setting that I bought new. I got the second one because of the way it performed on my k1000 for my wife to use on her k1000. Odd as it may seem, it has been on of my favorite film lenses.

I had two Sears 135s that had stuck apertures with a lot of oil on them. On other lenses I had used a cotton swab to remove oil, but on these lenses, the oil kept returning from parts I couldn't reach. I was able to remove the entire aperture assembly from the lenses and soak it overnight in mineral spirits. That finally worked.

The oil comes from cheap lubrication on the focus threads vaporizing and getting on other internal parts. The "glow" you have on the JCPenney lens is probably oil on the inner lens element surfaces.

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!!!
