| Latest Review Posted | SMC Pentax-A 135mm F2.8
I purchased this together with a M135/3.5 to see how a manual focus tele lens would do on my K-3. I had expected to like the M135 better as there appears to have been some mixed reviews of this A135.
I was very positively surprised. I did some extensive testing, and found this lens to be very sharp. Wide open at f2.8 it is same as or better than my 55-300mm at f5.6 (good copy). Stopped down to f4, it is slightly better in the center and much better in the corners than the 55-300 at f8.
Compared to the M135, the two are about the same from f5.6 and higher. The A is much better at f2.8 than the M at f3.5.
The lens definitely generates some chromatic aberration especially wide open.
The lens handles very well, with the A setting being a definite plus. The manual focus is a pleasure to use, and I can't really deduct anything for it being a manual focus lens (doh).
Highly recommended! |
