Mine was the 272E version; the focus throw is approx. 270 degrees and the diameter 71.5mm. Focus limits are: full range, 29-40cm, and 45cm to infinity.
Looking back at the wide open shots I took when setting the AF Fine Adjust, I can see it was mildly decentred: not too much of an issue with flowers in the centre of frame and stopped down; might be something to be wary of if your subject is flatter and more square on.
Sharpness:
On APS-C very even across the frame except at the absolute widest apertures. Wide open, I'd rate it as 7/10. This rises to 9/10 at f/4, and stays at this level before falling to 8/10 at f/11. It drops again at f/22 to 7/10. f/32 is a usable 6/10, but shows all the dust on your sensor.
Contrast is excellent and the colours pleasing, but it's not quite so fresh feeling as the Pentax 100mm WR - greens in vegetation are lighter and brighter with that lens, for instance.
Aberrations:
- Purple glare around highlights at f/2.8, only if looked for at f/4, gone by f/5.6
No noticeable aberrations except when wide open.
Bokeh:
Wide open shooting is not my style. Out of focus areas are pleasant enough, but can be spoiled by the purple-edged highlights at the widest apertures.
Handling:
Very good. It may be bigger and heavier than 50-200 kit lenses, but it's still comfortable. It's deeply recessed, so the centre of gravity remains near the camera. If you've used a kit lens, then you'll be prepared for how much it extends.
I had no problems switching from AF to MF and vice versa, or using the focus limiter.
The focus throw of around 270 degrees makes manual focus a cinch; I even managed to focus stack successfully.
Given how deeply recessed the front element is I'm not sure the lens hood is needed, except if you're using a filter. Access to any filter is slightly awkward with the lens hood fitted; the hood reversed blocks the focus ring.
Autofocus:
I had no issues with focusing, but I would do it manually for close-up work. It covers a lot of ground, so can be slow - the focus limiter helps a lot. Once it thinks it's found its target, it tends to be bang on. Remember to configure the AF Fine Adjust setting on your camera.
Recommended?
Yes. If you don't have a macro lens, then YES! (Prepare to have your eyes opened).
Unless you need weather-resistance, I'd recommend the 272E over Pentax's 100mm WR as it should be 50-60% of the price and works well as both a macro and short telephoto. Purely manual focus macro lenses are even better value, though.

| Pros: | Sharpness, Macro, Aperture control | | Cons: | focus speed, noisy, fucus hunt | |
After using this lens for 12 months (quite frequently) i have found this to be an excellent lens overall with only a few minor issues.
Macro is 1:1 and just awesome. Portraits turn out beautiful with this lens and gives nice vibrant colors eliminating he need to always use RAW as the JPEGs turn out very very nice.
Picture clarity is amazing but lacks a little at long distances.
Where it fails a little is the noisy focus, often jumpy focus hunting and the focus speed is not as good as some lenses I own. Not as slow as a Sigma 35mm ART lens, but nowhere near as fast as my 55-300PLM.
Being able to set aperture manually is a big bonus when shooting manual.
Manual focus is easy after switching on the body and then the lens, a little tedious but effective.
Manual focus is a little speedy and a more turn for less focus speed is desirable for myself to fine tune a little easier.
All in all, I gave the lens a 9 but it should be around 9.5.

I shot this lizard in Barbados. This has been cropped by about 50% and sharpened and had the WB altered automatically. It shows the detail you can expect even if you only half fill the frame with the subject. Original file was 14+mb. More detail than can be seen in this version reduced during upload it seems.

This Tamron lens is very very good optically (surely by far the most important aspect of any lens) !
Sharpness is wonderful and out of focus areas are smooth and I like them a lot !
AF speed (on Pentax K-70) is ok, it hunts sometimes but AF noise is horrendous )-:
MF is easy enough to implement (pull back the lens focusing ring and switch camera to MF (which you don`t have to do but then the cameras AF will override your MF and the focusing won`t be very smooth)
As you probably know there sadly are very few macro lenses that fit Pentax cameras, this Tamron being one of them. I can`t compare them with Pentax lenses but I can compare them with both Sigma 105mm OS macro and Sigma 150mm OS macro lenses (Nikon fit) and both have superior AF in speed, accuracy and lower noise and are possibly even sharper ! However, both are bigger and heavier and more expensive too !
I do recommend this lens, it`s not perfect but it does allow a great deal of fine detail to be recorded !

This lens is an amazing value when you buy it used. There are older version with model numbers 72e and 172e, but this one is 272e which supposedly is best for digital sensor.
Never mind the macro capabilities, this lens is also an amazing medium telephoto on crop sensor. Wonderful portraits, sometimes even too sharp. Colors are very nice and the contrast follows. Auto focus is very fast when you use the limiter, which will not allow you to focus closer than 45cm but that's what you want for a telephoto.
I did a lot of searching for and researching about what telephoto to get for nice portraits. Those lenses are very expensive, as there is no Pentax 85mm with autofocus below $1000. Closest to my budget was Samyang 85mm 1.4 (which is MF) but that lens is not sharp until 2.8, so you get some nice bokeh but if you want sharp, then you need to stop down to (guess what) F/2.8.
Macro is a very interesting and satisfying form of photography and it does require a lot of experimenting and learning until you start producing something really good.
With this lens you have both macro and a nice autofocus telephoto.

It's a amazing macro lens. Very performant, sharpness. The only "default" is that it's a little bit slow (autofocus), but it's better to use the manual mode with a macro lens. It's clearly the best macro lens to beginning.

Almost ideal lens (may be, it lacks the ultrasonic motor)! I want the same, but for 135mm! And 300mm to!

I purchased used, not primarily to photograph macro; lacked on analog routine 135 mm.
The DA 70 / 2.4 behind this is the best lens, which I have.
F2.8 aperture portrait is pleasant and nice bokeh; f4: portrait is almost too sharp.
The limiter is very useful; the focus so is very fast and accurate.
Limiter without a little hunting.
Bokeh narrow on opening at the somewhat confusing
The front lens sits deep enough, it can be used without a lens hood.
Manual with focus adjustment on my old Pentax (P30n) is also useful.

Very reasonably priced lens that really gets the job done. I strongly considered the Sigma 70mm f/2.8, but knew that I would want the extra length for bees, and haven't been disappointed. Take away the horrible fitting lens cap (have gotten it temporarily stuck when switching caps around, with it landing on another lens), and the super-touchy lens hood (very stiff, and tough to find the grooves, but the front element is so deep-set, that I never use it for any real macro work), and I have nothing to complain about. Takes nice portraits wide open (softens things a bit), and while it requires using two switches going from auto to manual focus, it's easy enough to do. The only time I use auto-focus is for moving insects, so I don't even have to mess with it most of the time. I think the build quality on the comparable Sigma 105mm is a little sturdier feeling, but the Tamron is definitely good enough. WR would be nice for laying out in the grass when it rains, but if that's your bag, then you would have went for the Pentax D-FA 100mm.
This is far and away my most used lens, and gives me consistently great results. Very little CA wide-open, and extremely sharp at f/8. I'm at a point where I rarely shoot this lens in raw anymore, just going with the in-camera "vibrant" setting, and snapping jpegs all day. It also produces some of my best bokeh shots. Really nothing more to say that hasn't already been said. Just an excellent performer that never lets me down. Here are a few pictures to end this

I wanted to link a picture taken with normal magnification, but this is my first 1:1 macro, and I'll be using it primarily for that. The only other time I'll use the Tamron over the DA 18-135 DC zoom is when I want a faster aperture than f5.6 at this focal length. I've got an A 50 f1.7 for portraits, which only puts 10 feet between the camera and the subject instead of 20. On an APS-C camera, this isn't practical as a portrait lens. It has an aperture ring, so I could use it with my Super Program film camera, and I'll take my last roll of Velvia film with this lens. It would be nice to have something like quick shift, you need to set the lens and camera to MF and leave it that way, but for macro photography I prefer manual focus anyway. Considering that the DFA 100 WR is almost twice as expensive, I am more than happy with this lens.
