Excerpt: Half year ago I have decided to buy macro, but didn't know which marcro lens to buy. But I was decided to longer FL so aviable were only 100WR, Tamron 90mm and Sigma 70mm. Reviews is recommending Tamron becouse of price. But here, price diference is only 70 bucks, so pentax DFA 100 WR is winner!
Excerpt: For the price of this lens I did expect a bit better build quality it feels light and cheap and a bit wobbly and it just is not a one off as I have had 2 of these.When I mount a ring flash on this lens the focus barrel sometImes does not want to move which is probably down to the clutch on the quick shift and this is in manual focus mode which is what I used it in 90%of the time.
Excerpt: 100mm is my preferred focal length for macro work as it provides a comfortable working distance even at maximum 1:1 magnification. externally, the build of this lens is fantastic. The fact that it is weather resistant also speaks to its proper design as an outdoor working lens. Pentax has (again) provided a wonderfully balanced and functional hood that is appropriate for the intended use while not being so large that it would discourage its own use.
Excerpt: This is certainly one of my most prized lenses even though it is not one of my most used. Outstanding as a mid length telephoto and macro. The sharpness allows a lot of cropping without a loss of resolution especially in telephoto shots so I can get shots equivalent to a 200 mm tele. Autofocus is quick and accurate. As a macro I find more need for manually helping the autofocus. This is where quick shift really helps.
Pros: Exceptional Sharpness, doubles as a telephoto and a macro, mostly metal build, convenient hood, autofocus in telephoto range, Compact and lightweight.
Cons: plastic filter threads seem thin, autofocus in macro range
Pentax 100mm f/2.8 Macro SMC P-FA review by kiwijono
8 February 2014
Summary: I was worried about the purchase at the time (you can never be sure of what you are going to get with online auctions) but now I realise I got a bit of a bargain. The focus limiter is a very useful feature and I now would not like to be without it (pity DFA macros don't have one). Sharpness is impressive. Even at f2.8 it pretty sharp and at the other end f16 is very useful (and surprisingly sharp still) for macro work.
Pros: Very sharp, focus limiter, nice feel to it, good bokeh
Excerpt: That said, it's not 100% perfect: the lightness comes at expense of build quality -- it certainly feels less solid than other lenses in Pentax's lineup, and you'll want that hood in order to protect the front element when you're doing macro work. The AF is noisy, which seems to be a problem with many of Pentax's macro lenses, and has a habit of hunting when you're close to the subject. (It's quite quick at longer distances, however.
Cons: Build quality, noisy AF, soft wide-open, purple fringing
Excerpt: It is my first true macro lens and it charmed me during 1st photo session. Extremely sharp, compact lens with, as usually in Pentax, brilliant contrast and colour rendition. It's really pleasing to fell solid metal barrel with comfort and precise focusing ring (do not expect K/M series feel, but it's still fine).
