| | This review is for a mint condition silver 'Made in Japan' FA31 bought second-hand in Sweden, serial nr in the 0027xxx-range. PROS- Build quality
- Look and feel
- Unique offering (like all other Limiteds)
CONS- Inconsistent autofocus
- Wide open sharpness
- Value for money
I USE IT FOR- General purpose (normal lens on APS-C)
- Low light
- Travel
The first Limited I got was the DA40, and soon I started to buy them one by one as mint second-hand samples came on the market. After a couple of years I got all the DA Limiteds and I was pretty well covered (I don't shoot much longer telephoto). There was something mythical about the FA Limiteds though, so after a while I started to look for them as well. The FA31 was the last one I got of the "three amigos" (FA31/43/77).
Most of my serious work is portraits and I was well covered with the FA43/77 AND DA40/70 (the plan was to sell the DA's, still haven't a couple of years later...). I get that at fast wide-angle is expensive, and considering the parameters of the FA31 for what it offers on full frame it is simply outstanding.. but on APS-C it becomes a pretty expensive normal lens.
To go trough the basics first. The lens is sharp. Like all lenses it is softer wide open, but it builds up gradually. It is sharp enough to use wide open for most applications, but I still feel a little bit disappointed. If I don't need the speed I will stop down to f/2.2 for a boost in sharpness. With nine apertures blades it the bokeh stays nice at most apertures, so you don't need worry about stopping down with respect to that. The bokeh is very pleasing, with a bit of character as well, just as I like it! One of the drawbacks of the lens is various aberrations, where lateral is an easy fix in PP, but where longitudinal is not. It might be disappointing if you are looking for perfection, but it hasn't bothered me. It adds to the character, just beware of it before spending the cash. I've read a few comments about "medium format feel" on APS-C, and I get that a fast wide angle is rare and shallow DoF with that wide (not so wide on APS-C) angle is not so common, but I don't feel that the FA31 offers something that other similar combinations would in that respect.
Autofocus is fast, but not as fast as the DA Limiteds. I don't mind the screw-drive noise, but in these SDM-days it is worth mentioning. I have used the DA*50-135 for a while and even though it has SDM it was slower than the Limited-lenses (although more silent). Also I wouldn't think that I should miss quick-shift from my DA Limiteds, but I guess that I use it more than I thought. It can be small situations like when you are about to put the camera in the bag, you want to retract the lens (focus to infinity), and then you have to fiddle with the AF/MF-switch on the camera. Small things, but I think it is worth mentioning. Build quality is otherwise on par with the DA Limiteds, which is to say very good - tight tolerances, nice materials. The aperture ring has a very slight play though, but as does my FA43 and FA77, so I think it is supposed to be like that. The leather case of the FA Limiteds are a bit sturdier than the DA Limiteds, also the cap has a nice green felt, great premium feel The size of the lens is pretty small, but I just keep thinking that it would be really amazing on a FF sensor, now it is more what the FA43 would have been on FF. A letdown if the FA31 is autofocus consistency. On the K-5 it both front- and back focused so I rarely used it even near wide open, but on the K-3 it has gotten better (not perfect though). Actually, it fits very well on the K-01 and with its contrast detect it doesn't show the front/back focusing problems. It is also a good match for both size and looks It is not optimized for manual focus though, focus throw is very short (as with most AF-glass), but has a slightly longer throw than the DA-series.
I have mixed feelings for this lens. It is not perfect, with a few aberrations and focusing problems (phase detection). It also goes from being a rare fast wide angle to becoming "just" a fast normal lens on APS-C. I keep thinking how wonderful it would be on FF (and that has been shown on film and the Sony A7-series). But, I don't feel that there is any real replacement. It has a nice character, it serves several purposes, and it has a very nice build and feel. If you are willing to compromise there are options like the Sigma 18-35, FA35/2, DA35/2.4 or Sigma 35/1.4. Each is a compromise of build quality and/or size, although they are cheaper Pentax K-01, SMC Pentax-FA 31mm F1.8 Limited. 1/80 sec at f/2.0, ISO 1600. Pentax K-5, SMC Pentax-FA 31mm F1.8 Limited. 1/60 sec at f/3.2, ISO 100. Pentax K-3, SMC Pentax-FA 31mm F1.8 Limited. 1/180 sec at f/4.0, ISO 100.

Bokeh is the best I've ever seen for a wide-angle. Pretty sharp.

| | I've always wanted an FA Limited but am unable to afford one until now. I find the most useful for me to be the 31mm focal length. It's really amazing, i've never had a lens like that even if mine is a used copy... i would only go for a Made In Japan copy over an Assembled In Vietnam copy... I found one that is almost perfect.

| | Construction: + very nice (metal feel, smooth operating focus ring) - the front part extends when focusing and is not all tight leaving a little "wobbling" (I suppose there is an engineering reason for that). A big plus is the presence of the aperture ring that will allow me to use it on a film camera.
Sharpness: this lens is sufficiently sharp wide open even in the corners. It gets sharper when closed down. At f1.8, I find the FA 31 sharper than the new Sigma 35 f1.4 that I own and that I consider very sharp.
CA: less than my FA 77, DA 50 f1.8, a very little more than the DA 40. OK for Pentax lenses.
Auto-focus: fine and fast enough for what I want to use it for.
Bokeh: superb
Colors out of my K5 with the FA 31 are great. It is expensive, but I believe that it is worth it.

| | There isn't much that I can say about this lens that hasn't already been said.
If you're looking for a "standard" prime on a Pentax DSLR with APS-C image sensor then there is no better lens than the FA 31mm F1.8 Limited.
The bokeh from this lens is nice and smooth even when you stop down a little for some extra DOF. The way this lens renders details and specular highlights is nothing short of exceptional. The build quality is typical "Limited" excellence.
You can find some aberrations in some but it's so minimal that it's largely a non-issue. Len flare when you're shooting toward the sun can be annoying but if you add the long end of a Panasonic FZ18 adapter tube to the lens (as mentioned several times in the forums here) the modified "hood" solves the worst of the flare issues.
Some DSLR users might find the lack of quick shift manual focus to be annoying but I've found the AF quick and reliable on my K-5 IIs and K-01 bodies and if I ever need manual focus I'll flip the switch on the body.

| | What can I say that others haven't said before? I never cease to be amazed by this jewel of a lens.
Update: I have now had a chance to use this lens on the full-frame K-1, a purpose for which it was surely designed. I must say, that I am blown away by the amount of detail the camera/lens combination can capture, something to which the reduced image uploaded can never do justice. The lens is insanely sharp at f5.6, and the rendition and micro-contrast are simply awesome. | | | | Veteran Member Registered: February, 2009 Location: egypt Posts: 435 1 user found this helpful | Review Date: September 17, 2013 | Recommended | Price: $1,400.00

| | I've used the 31mm FA Limited for about seven months now and feel I can finally write a reasonable and informed review after my recent trip to Japan with it. In three weeks, I shot about 7,000 photos with this camera at the beach, near the ocean, being splashed by some inconsiderate jerk at the ocean, inside a bulk fuel storage tank, inside an incredibly hot fuel pump house, in two thunderstorms, and in a crowd exceeding 20,000 people. In every situation, the lens performed beautifully on both the Pentax K-7 and Pentax K1000 that I brought on the trip.
Note that during rain, when I was splashed, and in a very-find-dust environment when entering the fuel tank I kept the camera wrapped in plastic to prevent water and dust from getting into the lens. This lens is NOT weather sealed (I don't think it needs to be) and should be protected in harsh environments.
This is the sharpest lens I own. I use it for photographing people, objects, and architecture. In each case, it performs well. The AF is fast enough to focus on people moving quickly at sporting events. But sometimes the lens is TOO sharp. With some people, the lens captures so many details as to make portraits unflattering. In some cases, this lens has made the people I photograph look about ten years older. Typically, the lens is honest in how it portrays people, but for people with wrinkles or lines, it grabs onto them and really makes signs of age apparent.
For architecture and product work, this lens is tops. I think my photos will speak for themselves.
This lens, today, is going for between $1,200 and $1,300. I picked it up for $989 a couple years ago. Could I justify up to $300 more if I needed to replace this lens -- YES. Emphatically yes. This was a great purchase and has, in very short order, become one of my workhorses and a keystone in my lens lineup. In fact, this lens' quality spurred me to pick up the 77mm FA Limited lens last month.

| | I will make this one short. Do not expect sharpness across the frame at wide apertures. I am cracking up with some of the reviews that list that as a downside. If it was sharp across the frame at 1.9 we could pretty much throw away the ‘bokeh’ category… because it wouldn’t have any. That is one of the main benefits to using a wide aperture. Also folks, aperture has a relation to focal distance. Don’t expect a sharp image if you are shooting a landscape at infinity at f/2. I would say the strongest point of this lens is the bokeh. One of the smoothest around. Produces excellent ‘portraits.’ The sharpness is the second strong point. The slice of focus at the wider apertures is very sharp.. but granted, it is just a small slice at the wide end, as it should be. A little bigger than most primes of this focal length but it is a good universal size and weight for most cameras. That is my short review as many others have said the rest.

| | I was longing for this lens for a couple of years. I hesitated to buy it because it was somewhat pricy and I had DA* 16-50 which produces really great images around that focal length, even wide open.
However, I had had FA77 and wanted something in the same league for wider angle shots. Finally it was time to upgrade the aging K-7 I had and I couldn't resist any longer and ordered FA 31 as well.
The first impression was rather disappointing because it just wasn't sharp the way I expected wide open. FA 77 was much better at 1.8 in comparison. However, stopped down to 2.2-2.8 the sharpness of FA 31 was just brilliant in center and across the frame.
Another source of disappointment was the lack of expected 3d effect. I can point FA 77 pretty on everything and it magically produces an appealing image, often having that 3d feeling. I couldn't do that with my copy of FA 31. I blame "Assembled in Vietnam" stamp as opposed to "Made in Japan" of FA 77 but not sure since I don't have another copy to confirm that.
It was not that I didn't like it, I found it amazing at landscapes or group shots at f/4.0-5.6 but taking photos at 1.8 was something I couldn't afford myself. I decided to wait until I get used to it before making final judgement.
Now, after a year passed, I think I've finally found the way to use it properly. The point is that the lens open at f/1.8 produces great, sharp images when distance to subject is very close. I'm not sure if this is a design flaw or some feature of this lens copy or just focusing issues but now I don't hesitate to shot wide open when choose the subject properly:
All in all it is a superb lens and the competition's equivalents are just monstrous, albeit a stop faster. I hesitate to switch brands because of great Pentax FA 31 and FA 77 lens - there is simply no substitute.

| | An updated review after a few years...
This lens is nearly perfect in every way. The "personality" of the images it captures are unlike any other lens I have used. It is equally brilliant as a normal prime on APS-C and a wide angle on 35mm. In the hand it feels like an extension of one's mind...it really is that good.
I've had this lens for maybe 5 years now, so I have come to learn some of its...idiosyncrasies. The biggest drawbacks I have found have nothing to do with the images, however. The first is the silly lens hood, which is so small it seems to only be good for use at noon in the tropics. This lens is so flare-resistant a hood is unnecessary, but it would be nice to have the option of using a "real" hood if need be. I use a few old flare-prone color filters with B&W film that could really use a good hood in certain shooting conditions. The second issue is with the lens cap. It is a beautiful piece of machined aluminum to be sure, but the felt has a tendency to gather dust and grit, which has resulted in a good deal of brassing along the front edge of the lens hood. A minor point, and I personally like the look of a well-loved lens, but something to be aware of.
