Overall
Owner since: more than 10 years

User profile: Semipro
Cons: Terrible build quality and AF mechanism lacks precision and doesn\'t stand up to long-term use, sometimes jamming. Aperture cable can become faulty. Rear element is a cemented doublet which fogs up with time.
Pros: Optics are extremely good for something so small, light, and cheap. Contrast and micro-contrast are both lower than my Sigma 105mm OS, but I prefer to have one of these on my camera as they are so much smaller and lighter. It\'s quite good at 3.5, with fairly obvious vignetting on full-frame, as well as some corner softness, noticeably sharper at 4.5, and excellent at 5.6 and 8 everywhere in the frame, and at all focused distances - this is easily good enough for general use as a super-portable 100mm.
Summary: For most applications, I actively prefer it to much more expensive macro lenses but would love it had they made it more durable and reliable.

Cons: has a cheap look and feel
Pros: I use this lens as a cheap option for my Canon 6D. I had a Sigma 105mm Macro before, but that had a focus issue so I gave it back and bought this lens for the meantime instead. But not sure now if I want to give it away again! This lens works pefekt on my 6D - focus is on spot and for my purposes quick enough. Sharpness is already very good at f3.5 at close-ups but also for objects further away. I didn\'t expect that quality at all and ask myself if I really do need an original Canon Macro lens for my needs. Another great point is, it is so light. Last not least - no thief will really want to take a risk stealing your camera with that lens on it :)
Summary: Together with my Canon 2.8/40mm I have a great and light travel equipment with very good picture quality which will hold up or even outperform the latest L-Zoom lenses. But that might be unfair - a prime should be able to do so - but 50 bugs for such great picture quality really makes you wonder.

Cons: the build,some people call it joghurtcup.... a bit noise,sometimes the autofocus hunts lenshood must be purchased seperatly most of the time care must be given to buy one which comes together with the matched achromat
Pros: nice for portaits,100 mm the matched achromat is of good quality ideal for beginners and amateurs who want to start with macrophotography has become a cultlens,its very sought after...
Summary: for beginners and amateurs who want to experiment with macro,and for people who are on a tight bugdet. Is a nice portraitlens samplepictues on flickr,just search for cosina 100 mm and jugde for yourself
