Originally posted by winglik I believe your picture is at f8 or up. The drawback on Takumar Bayonet lenses are lack of sharpness at wide open and MC. i have the 135mm f2.5, it's nice when using at f8, but just not sharp enough at f2.5. I think that's the reason people don't like them, and for the same or a little more money, there are alot better lenses than the Takumar Bayonet.
You are corect that my shot is at f8, it's a pretty standard value for landscapes. I agree that it looses a bit of contrast at f2,8, but smaller than that the contrast is very even. I have not noticed any flare issues, and I did play around a bit with the Sun in my frame. My 135 mm takymar Bayonet is pretty sharp at f4, much more so at f5,6, you don't need to go to f8 to get sharp results.
Quote: i can't comment on the 28mm version, but I have the 135mm f/2.8 one and it's been a blast to use. the perspective and field of view on film is great, and on digital, it's a nice tight crop portrait lens. it is very sharp and renders background OOF quite nicely. i dont have another 135mm lens to compare it with, but i would imagine it would perform as well as any other 95% of the time. the 5% that it fails is when there is a light source hitting the lens at exactly the right/wrong angle to cause a picture to be washed out.
i'm sure this 28mm'er is exactly the same. i wouldn't consider it a "secret gem" or anything cuz it does have its shortcomings, but it's definitely a good workhorse lens that can be had for cheap. the reputation is undeserved.
I agree about your comments on the 135. Its build quality is actually fantastic, better than most other lenses I have used. the 28 is equivalent, feels and looks like an M lens (except for that aperture ring).
I agree that it's not really a "gem" but it's way better than what I would have expected.
the problem is that, between my sigma 17-70, F 50 mm f1,7, and Vivitar series 1 70-210, there isn't much room for lenses that are not comletely fantastic. That's why my other primes don't see much use. But from time to time I go out with just the primes, in order to work a little bit and "earn" my photos, so to speak.
Just1MoreDave, thanks for your advice, I believe I'll try it. It doesn't sound like there's a lot of risk involved...
