Excerpt: I'm a very dedicated amateur photographer who spent years using "bridge" digital cameras before finally getting an SLR last fall. That said, I've used the close-up function on "bridge" cameras regularly to take shots of creatures, flowers, vegetables, etc.--but I've never experienced anything like this lens. I've mainly been using it for macro shots, but the few portraits I've tried haven't disappointed me.
Excerpt: So far I really love this lens. This is my first macro lens, but it is really sharp, I'm finally getting some of the stunning photographs I used to get with my film camera. Once in awhile it has problems with the focus, but otherwise it's really great.
Excerpt: I have only had a short time but have had lots of fun with it already. The 100m macro is so much more than the 50m I used with my film camera. Unbelieveable shots of common flowers not appear spectacular. Fcousing ring is sooooo smooth. I look foward to trying it on potraits. Just alot of fun, just like my 10-17 Pentax, only sharper.
Excerpt: This piece of gem is fantastic ! There is no reason at all to post process the files, the images this lens provides are outstanding right out of the camera. Colors, bokeh and the amount of detail, especially after cropping, makes you want to sleep with this lens under your pillow. The only drawback is that it sometimes hunts for focus but as macro lens, you would want to play with MF anyway, and I enjoy every moment of that play : ) The best thing about this lens is that...
Excerpt: I love shooting macro and this lens is perfect for my needs. I like that it's weather-resistant because when I shoot outdoors, I tend to catch all sorts of little creatures in the early morning (when they're not quite as active) and that can often mean a lot of humidity in the summer. Coupled with the K-5, I don't think twice about being in damp weather. This lens stays on my camera or in my kit bag.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Nice Bokeh, Rugged, Strong Construction
Summary: Excellent macro abilities, 100mm telephoto angle of view is perfect for cropping out unwanted subject matter. F 2.8 is great for some low light conditions, but is even better combined with the macro for depth of field control. I'm looking forward to shooting many close up shots with this lens.
