Cosina AF 100mm F3.5 MC macro A-mount lens review by hpmickey
|hpmickey#6910 date: Feb-14-2010|
flare control: 5
|ownership:||I own this lens|
|price paid:||~ $150 (used)|
- very light
- neutral colors
|negative:||- extremely loud AF|
- very slow AF at macro distances
- prone to collect dust inside
|comment:||I have bought the lens used but like new. Although I did not use it extensively, one annoying dust particle has appeared inside after a month of usage. Fortunately it does not seem to affect the image quality.|
Now after a year and half or so, I have found myself to use it more as a portrait lens. The AF is surprisingly fast in this case. I have shot several landscapes as well and the sharpness is very good even when focused at infinity.
Compared to 100-200/4.5, it is sharper at 100/4.5 but seems to have a little less contrast. At F5.6, I would say, the contrast is equal, and the sharpness still a bit better.
