I also have to remove one of aperture's end stops to allow clearance for new spring.
The lens is relatively heavy, and as another reviewer has previously mentioned, the little lever on the side seems pretty pointless.
When I bought this, I'm not so enthusiastic at first, thinking that it would not be as good as.8 lens.
Grab one when you can!Anyway I don't mind too much as it seems to have made the lens a killer medium distance lens.This is probably why the lens was so inexpensive.quot; name'ClassicSPB' date'12.4.2011, 22:32' post'983134'.Lens Review Date: February 20, 2013 I can recommend this change ip address mac for netflix lens: Yes Price: 170.00 Rating: btooom episode 11 sub indo 9 Pros: Contrast, Sharpness, Builtin hood, Smooth Bokeh despite only having 6 blades, Beautiful lens Cons: Not for lowlight photography, need to bring a bounced flash I use this lens.I haven't had this problem with any other M42 lenses.A great find for a ridiculously low price, thus I'm not going to enter the amount into the database.Lens Review Date: November 21, 2011 I can recommend this lens: Yes Price: 150.00 Rating: 10 Pros: Sharp, neat colors, easy to focus, sharp, and great IQ overall Cons: None so far I finally got this lens, I thought that my SMC Pentax K135f2.5 was.In a blind test, this lens from f/3.5 to f/16 will beat many lenses, yet you can buy it for under 100.Very sharp from 1-25m from around f4 upwards.Lens Review Date: November 23, 2010 I can recommend this lens: Yes Price: None indicated Rating: 10 Pros: solid Cons: pin sharp 135mm.All of mine are the "Zebra" version with a DDR on the front and with serial numbers around 9,386,000.I was wrong, it performs much better than a bunch of my 135/2.8 lenses.Cons: Aperture mechanism is a mess!
