I've bought this lens mainly for location portraits and model shots - and the test shots I've done so far confirm that in image quality this lens will sit worthily alongside my 70mm Limited. I'm not entirely sold on the lens' looks though, as it's a bit of a plain tube or even like a lens on top of extension tubes. And the lens hood is so long it manages to unbalance the K-3, even with it's battery grip on! I'm not sure how necessary that is for the hood as the front lens element is quite recessed anyway
But although I have some reservations about the design, the fact remains that this lens is a top-notch performer and a worthy addition to any Pentax lens bag.
The Pentax 100mm f/2.8 Macro is an exceptionally good lens. Well built and weather sealed. It is absolutely tack sharp at all focal lengths and great as a general lens not just Marco. It works perfectly with my Full Frame Pentax K-1 with no vignetting.
Really nice lens gives really good results, has a non-rotating front element and a little trap door at the bottom for adjusting a polarizer in the lens hood. This will be my no 1 lens unless I want to go for extra wide or tele shots. Suits the k-1 nicely and is usefully wide at the 28mm end on full frame FF setting. Nice to handle & all the rings turn smoothly (Compared to my Sigma) and balances with the camera. This is the lens for general out and about hand held shots. Pricey compared to APC lenses but well deserves 5 stars. And of course it works with the APC Pentax's if you want to upgrade in steps.
This review would be 5* but for one major point. No focus limiter. A weird omission as it was on a previous model I owned from many years ago. It's compact, light, weather resistant, with an aluminium outer casing, all plus points. Optically great, especially when closed down a stop. There are no manual controls, everything is electronically operated from the camera body. This is a minor criticism from someone who was using cameras to photograph Noah. Anyone new to photography will not even be aware that the old features might be useful sometimes (they won't, times change).
In conclusion, well worth the money. A lovely lens.
This is a lovely lens. It feels solid and very well made and is nice and compact. Image quality is great and it takes very nice macro photos. The first one I got did have an issue with the focus ring catching on the lens hood making an irritating squeak but Amazon replaced it without any issues. The only issue I have found is that focusing is slow and it does have the habit of hunting through the whole focal range due to the lack of a focus limiter and using screw drive focus. Otherwise I am very happy with this lens. Now just need more time to play with it!
