| | from the "100-300" zooms this lens is a best, I think.
it is 80-320, little wider, little longer, F/5.6...
if You have FA 35-80/3.5-5.6 it will be consistent not expensive (budget) set at FF, for crop possible to use "kit" 18-55 if wide angle is needed.
as I say before - not expensive (F/5.6)
good AF, good-filling touch.
compact enough, when retarded...
real cons only round hood is needed, and not to much easy to obtain one deep enough, but I am using short one (20mm) - it is Ok.
for using as long telephoto zoom time-to-time, some birding or something else is good, very good.

| | This is not the best of lens but it is good for it's price, especially in today's market. The optics are good, not great, and handling / build quality could be better. I was looking for a longer focal length to play around wit and this lens fell into my lap. In my opinion, it's not an every day lens. It doesn't measure up to other lenses I own but it's a fun lense to play around with, especially if you're looking for a longer focal length. If you find one cheap, buy it. You have nothing to lose and you will likely be pleasantly surprised by it's results. [/url]

| | Surveying the used market and previous reviews, I bought my silver version in 2021 for $80 with tax for my K-5 camera.
I was very attracted by the 480mm option.
It was my first lens in addition to the kit lens. It turned out to be a pretty good decision.
I mainly wanted to photograph birds and wildlife with it.
It roughly meets these needs, but with limitations.
Then I experienced that, like all zoom lenses, it no longer performs well at the end position.
I can count on a sharp image from F9. It is not for photographing fast-moving, flying things.
Using in the right conditions, if it gets enough light, it is a reliable partner.
If the conditions do not suit it, the product indicates.
The autozoom wanders off and hunts long and noisily.
Unfavorable lighting is shown by purple fringe CA. Fortunately, this can be handled well in post-production.
I am grateful for all shared experiences!
I took mbukal's advice and added a lens hood. It's not comfortable, but it makes a lot of difference
to the quality of the result.
Later, I understood and began to consider northcoastgreg's experience as well.
All in all, I found it to be a very versatile lens for its price-value ratio.
It performs very well by avoiding its sensitive points.
Overall I recommend it.

| | I bought this for just $40 off US ebay, but then had to pay import duty to the UK. For that price it was a bargain. I wanted a lens for a safari to Botswana and this lens proved ideal. At 80mm it gave wider shots of groups of animals, and zoomed in to around 250mm it seems very sharp, and acceptable at 320mm. The edges may not have been so sharp, as others have described, but given I was focussing on animals that were fairly central in the frame, softer corners were no problem.
Just to add that before this I had a Sigma 75-300 Apo zoom, but I rate the Pentax as better both in handling and image quality.

| | This is a difficult lens to rate, because the optical quality varies so widely. In the optical sweet spot (f8 to f15, 80mm to 150mm), it is little short of stunning. But it's only moderately sharp wide open (and then only at the wide end), and performance worsens as one zooms toward the long-end until, at 320mm, it never really gets sharp at all, even stopped down.
When the FA 80-320 was released back in 1997, it would not have been considered a consumer grade lens. According to the patent for the lens, the objective of the design was "to provide a small telephoto zoom lens having a zoom ratio around 4 and exhibiting a high performance over the entire zoom range." This is obviously a more ambitious lens than the other FA (and FA-J) variable aperture telephoto zooms Pentax introduced between 1991 and 2003. Build quality, despite the largely plastic exterior, is tight and solid—definitely a step up from the FA 100-300 f4.7-5.8 and the FA-J 75-300. The lens, despite the patent's claim to being a "small telephoto" does have some heft to it. But it's not nearly as large and heavy as pro-level zooms like the FA* 80-200 or more recent full frame telephoto zooms like the DFA 70-210. Although this is a variable aperture zoom, it's rather odd in that the camera recognizes it as an f4.5 zoom all the way to about 200mm, before jumping two-thirds of a stop to f5.6. The lens is obviously not relaying it's true aperture to the camera.
In the late nineties, expectations of lens performance was not nearly as high as it is today, so the FA 80-320 could pass for a mid-range lens twenty years ago — but today not so much. Which is a pity, because if you are willing to stop the lens down and avoid the long end, you will be treated with a lens that is not merely equal, but in some respects superior to, modern mid-range lenses (such as the aforementioned DFA 70-210). While I had expected the lens to perform reasonably well toward the wide-end stopped down, what I was surprised to discover is how well the FA 80-320 renders objects against backgrounds. It hardly matters whether those backgrounds are in or out of focus. Objects are rendered with a sense of dimension, of tactility, of presence and depth that is rare to find in any zoom lens, let alone a variable aperture zoom. Since acquiring the FA 80-320, I have lost all interest in the DFA 70-210 or any other modern telephoto zooms. The modern glass is better for wide-open shooting, but as a landscape shooter, even f5.6 is useless to me. Hence for landscape photography, this really is a superb option in the 80mm to 135mm range. Even at 200mm, it's still pretty good, although you'll give up some corner and far edge sharpness. The long end can be used for sunsets, where resolution usually doesn't matter much.
The problem, I suspect, with the FA 80-320 is many people buy it to photograph critters and other objects at a distance. This means shooting wide open toward the long end. But that's precisely where the lens does not perform well! This is just not a critter lens. It's a lens for landscapes and scenics. For that sort of photography, you may find, among modern options, lenses that are sharper wide-open or have a bit more contrast (because of advanced coatings) and better CA control (because of ED glass). But you won't find a lens that produces more beautifully rendered landscapes and general scenes.

Mine is a second hand lens the silver version, everything on the lens works really good and the condition of the lens overall is great, the focus is good although a bit noisy, sometimes gets purple aberrations but really not to noticeable.

P.S. My FA 80-320 mm just died on me. When the lens is set on "A" so the camera body governs the diaphragm setting, the body can no longer read and adjust the f-stop. When I permit diaphragm activation in the Menu, it works only @ f/4.5 whichever manual f/stop I try to use. I replaced it with a demo DA 55-300 mm HD I found cheap on eBay. It's the first time I have to say "adios" to any lens I ever purchased (SNIFF !).

| | The silver version, not black,bought used on ebay , later purchased a metal hood from ebay because there was no original 58mm and 62mm was added on her later , it was necessary to calibrate, done in house work, I found a description of the action and succeeded from the first.
The lens is lightweight and it looks quite firmly and surprisingly large optical IQ as it is a lens kit with such a low price. After calibration satisfyingly sharp across the full range and nominal apertures, the hey f5.6 to 320mm is super. With the replacement hood contrast throughout the range is super, neglected with vignettes, it also suffers from creaking / pulling the lens when it is facing down, focusing is fairly quick and decisive in good light but loud, at low / poor light the focus is pretty bad because a lot of it goes first to the maximum and then returns to the minimum and then searches for the focus - that's the only bad thing (very noticeable and sometimes frustrating) high-capacity lens with low price.
Successfully focuses on good light and via a Pentax AF x1.7 adapter (at maximum nominal aperture f5.6), * sometimes you need to zoom in / pre-focus on the lens itself to make the focus fast and reliable via the adapter (satisfactory quality in FF on Pentax FA lens with 550mm and maximum aperture f8 -We have to be aware of the compromise for the autofocus for that mm and such a price )
Before I used K-x / r / 3/30 with Pentax-DA 55-300mm F4-5.8 ED or Sigma 70-300mm F4-5.6 APO DG Macro now FA 80-320mm F4.5-5.6 on K1 I look sharper and with a better focus in good light
I would like Ricoh to have / make a Pentax DFA 70-320 / 4,5-5,6 ED PLM WR RE with quiet / fast and determined autofocus (equivalent to approx. 550 ~ 600 euro in Europe) .
Then there would be a telephoto zoom lens sequence for FF = beginner / advanced / professional series (70-320 / f4,5-5,6 + 70-210 / f4 + 70-200 / f2,8)
My recommendation to use at K1 if you need a long / optically decent / cheap lens.

| | This lens (gray version) is better by far than my 55-300 that will be sold. Maybe the focal range with APS-C is worst but but that depends on the use:
-Is a bit longer.
-Is a bit faster, aperture and focus.
-Has a bit better IQ.
-Has less vigneting.
-Has less distorsion.
-Has 8 blades so bokeh is better.
-Cormatic aberrations are similar.
-Is more solid, like the most old stuff.
-If someday you upgrade to K1 you will can use.
I have to microadjust the AF to -5 to get a perfect focus.
Mine has a problem, cant focus to infinity but that is so easy to fix.
1-Take off the bubber front ring
2-Take off the 3 screws
3-Take off the plastic ring
4-Zoom at 320 and rotate focus ring to infinity
5-Now you can see 3 more screws with something like rails.
6-Loose this 3 screws then rotate a bit the front barrel to left.
7-Try if now can focus to infinity
8-YES? Mount it again NO? Rotate a bit more to left the front barrel.
Now you have a good telezoom!!
9-Buy a hood
Now you have a GREAT telezoom!!

| | I have the silver version, made in Taiwan bought secondhand from SRS Microsystems with a one year guarantee.
I'm really enjoying using the lens when out in the countryside. Using the TAv setting on my K-S2 it's possible to get some cracking long distance shots fully zoomed out, obviously DoF can be quite shallow then.
I'm still experimenting with settings but find for animals/birds anything around F9-F16 and 1/320-1/500 give good results. You can also get pretty good close-ups (flowers etc.) using similar F settings and slower speeds around 1/160.
The focusing is quite noisy, but very fast, usually locking on without hunting when using the viewfinder - I've not tried LV with it.
Overall I'm very happy with the lens and probably won't need anything longer (APS-C = 480 35mm equivalent focal length).

Si bien a mas de 250mm decae un poco el rendimiento, sigue siendo usable hasta en la focal mas larga. El enfoque es algo lento, pero nada preocupante. La version color gris, tiene rendimiento optico y mecanico superior (inexplicablemente porque en teoria son identicos) El peso es contenido y el tamaño tambien. Combinado con los altos isos que permite el sensor sony de 16mpx permite olvidarse de aperturas de 2.8, del 70-200 y poder trabajar en interiores sin problemas, incluso en focales mucho mas largas.

| | Purchased the lens for more reach to shoot birds, animals.
It is very compact at 80mm, which is nice for storage. However, that mean it extends a lot at 320mm. It experiences lens creep especially when pointed straight down, which might be a negative for some people. Autofocus takes some time to go from one end of the ring to the other end, rather noisy. But that is to be expected of screw drives motors!
For good results, I usually stop down to around f/8. Sometimes the smaller aperture can make a significant impact on haze in adverse lighting.
For it's price, it is an excellent lens. Here are some example pictures! https://500px.com/photo/107454153/landing-snow-goose-by-ncarr https://500px.com/photo/100567237/wading-blue-by-ncarr https://500px.com/photo/100571333/skimming-skimmer-by-ncarr (Heavily Cropped)
Also, I have the silver version, so no build quality problems or whatever else that is experienced by the black versions.
EDIT: lowered the value from 10 to 8 because of the ridiculously low price of the HD DA 55-300 f/4-5.8!

| | I got back into photography after a long break (last time was film) and from a (digital) beginner's perspective this lens for me has had the best cost($93) vs. value of any of my lenses. stock 18-55mm, SMC DA 1:2.4 35mm AL ($202USD) , SMC Pentax-A 50mm 1:2 ($50).
Agreed, as some have pointed out, the AF can have some difficulty but that can be minimized after spending some time to better know the lens. Some shots have had really nice bokeh as well.
A lot of people complain about the plastic feel and build of the lens however this aspect does not affect me at all. I could care less. The lens appears well built and delivers some really balanced sharp pics!!
I love this lens and as beginner moving toward a more accomplished photoguy I will hang onto this lens for a long time to come.
