Pros: Sharpness, size, contrast, speed, light
Cons: plastic body

I stumbled across my copy in a 2nd hand shop - they did not know what they had so I got it for a song. So far most of my the work I have done with this lens on K-S2, but have recently started working with it on the K-1. It's sharp right through it's entire range of f/2.8 - f/22, corner to corner, and is amazing for it's age and build. The only reason I gave this lens a 9 for sharpness is that the modern lens do beat this out - but it's close. You'd be hard pressed to find a sharper 28mm in it's normal price range. The only negative I can think of (if it can be considered as one) is that the lens correction in some PP programs is very heavy and needs some manual adjustment for full frame images.

Here are some sample images.

Pros: Small. light, quick to focus, excellent contrast and color rendition
Cons: Not WR, some plastic parts
Sharpness: 10    Aberrations: 10    Bokeh: 8    Autofocus: 10    Handling: 10    Value: 10    Camera Used: K-5, K-3   

I have a number of Pentax lenses from all of the different series, but for some unknown reason only one from the F series. It is the 28mm f2.8. It is one of my favorite lenses. It focuses lightning quick and is tack sharp to the edges from f2.8. Contrast and color rendition are second to none, IMHO. Even though I have the FA 31 f1.8 Ltd, which is close in focal length, and just a little bit faster, and a Limited, I don't see myself ever parting with this little gem.

Pros: Sharp, compact, quick AF
Cons: None for me
Sharpness: 10    Autofocus: 10    Handling: 9    Value: 10    Camera Used: K-1   

I have had this lens for ages, first using it on film and my istD cameras and other DSLRs. Since selling my K-7 a few years ago there was a hiatus for it to be used on digital. Then this year I bought the K-1 which boosted the use of this lens.

I considered before buying the 31mm Limited, but as I had this lens I am glad I did not. Seeing the results from this lens on K-1 convinced me that the +3mm in focal length and gaining one f-stop would not give me much advantage even considering that the Limited is considered one of the best Pentax lenses of all time. Well, for me certainly not, especially not for 10x the price.

Well i was very lucky to get a copy of this lens, Have been looking for a long time for one of these and found one on gemtree, I can't say anything bad about it, for the age of this lens you can't believe how it performs, i was looking at getting the FA version but found that this version proved to be just a little sharper in some reviews on the net, like this one, https://www.ephotozine.com/equipment/item/pentax-smc-f-28mm-f-2-8-274/reviews, and the colors are very deep, great for landscape and cityscapes photography. Here's a photo of my local beach. Fantastic lens.

Lens Review Date: April 19, 2016 I can recommend this lens: Yes | Price: $300.00 | Rating: 10 

 
Pros: sharpness, value, manual focus to infinity in dark (truth for all film era lenses)
Cons: aberrations (can be easily fix in post)
Sharpness: 10    Aberrations: 7    Bokeh: 8    Autofocus: 10    Handling: 10    Value: 10    Camera Used: K-5    Sample Photos: 1   

Sharpness: It sharp right from f2.8. I shoot a lot of cityscape, city night, and long exposure stuff. Sample image below is at f16, focus at infinity and it is very sharp.

Aberrations: this is one of its downside. But it is still better than FA35 and DFA100wr, IMO. To be fair, It can be easily fixed in postproduction. I recommend to get an ebay metal hood, it will improve the image quality.

Bokeh: It is satisfying for its price. Just donít compare it with a lens like FA31. It is like 3-4 times more expensive.

Autofocus: as I mention before, I take a lot of night cityscape photo. My K5 lowlight auto focus performance is useless on all lenses! Most of the time, I only want it to nail focus at infinity. 10 out of 10 times, K5 doesnít do it. But with a film era like F28, it is no problem to manually focus at it infinity. This is very useful for me. During day time, this lens has no problem focusing. Well, needless to say, every prime I have, never had a problem focusing on K5 during the day.

Handling: solid build lens. It doesnít feel cheap on my hand. And I prefer lens with plastic barrel. Yes, metal barrel is pretty, but I buy my gears to use not for correction. My 2 metal barrel lenses, dfa100wr and da 15ltd got multiple scratches all over its barrel. I feel so guilty every time I look at them. But with F28 plastic outher body, scratches are hardly visible.

Value: concerning its price, and what it can delivery in term of image quality, it would be a crime if I donít give it a 10! I got this lens second hand in Tokyo at around 32k yen. It is the cheapest prime I have, and so far, it is the best investment ever!
and I was looking at FA31 first but when I see this post, It change everything!

Pros: Sharp, Fast, well built, price for quality!
Cons: some CA, but just slight

I bought this to shoot newbie models. Unfortunately, manual lenses can be a burden when someone wants to pose quickly and is a little more impatient. So not having money for limited primes. I bite the bullet and bought this little guy.
It's a beautiful lens optically. Wish it was black and not dark grey, but not a big deal.

My copy is very sharp, I could not complain at all. It creates beautiful details. Blows my FA 50mm 1.4 away in sharpness, and to my eyes is as sharp as the Pentax-M 50mm 1.7. It's got great looking Bokeh too!

Lens Review Date: June 29, 2014 I can recommend this lens: Yes | Price: $160.00 | Rating: 10 

 
Pros: Size, weight, build quality
Cons: Very little
Sharpness: 10    Aberrations: 9    Bokeh: 9    Autofocus: 10    Handling: 10    Value: 10    Camera Used: ist and K5 IIs   

I bought my first SLR, a P30n, with a 50mm f1.4 in 1989 and have stuck with Pentax through 25 years of photography. Seven bodies later (five of which I still have, one stolen, one written off in a skiing accident) I finally decided the time was right to find a 28mm f2.8 to go with the 50mm and 100m macro f2.8 that are my normally walkaround kit. Finding one for the equivalent of 160USD made the decision even easier.
The lens arrived by post at 11am and at 3pm, after a few test shots, a thorough clean and the fitment of the obligatory Skylight 1B, I went out to a family wedding and started shooting.
Knowing that the venue was small and the family large I knew I needed to be able to shoot up close and personal and I cannot say how happy I am with the results. More to the point, so is the bride and over 80 of my shots, nearly 75% taken with the 28mm f2.8, are going in the album.
Having used the 50mm f1.7 for 25 years, and the 100mm f2.8 for over 15, the 28mm behaved exactly as I expected and wanted, and leaves me wanting nothing.
My advice: buy one. Soon.

I got this lens around 10 months ago, and it has been with my camera longer than any lens I have. This was perfect for me, small, sharp, and fast. I use this for portraits and landscape. At f4-f8 this little guy shines best. Been using it since I got it but I could never find any flaws. I really recommend this lens.

Pros: Sharp, even wide open, great colour rendition, good contrast, good build ( a mix of Metal and Plastic outside), Excellent Bokeh!
Cons: Some CA in extremis on APS-C
Sharpness: 10    Aberrations: 10    Bokeh: 10    Autofocus: 10    Handling: 10    Value: 9    Camera Used: Pentax K-5   

I only got this lens yesterday, but used it a lot today on various subjects.
Well, I can say, this is one excellent lens! Sharp from F2.8-F11 (not used it beyond this) contrasty, great colour rendition too.
The bokeh, in spite of "only" 5 blades is fantastic! Smooth creamy and not at all fussy.
I already love it!

Downside,
There is CA in high contrast areas which can be a problem. This is why I only put it as a 9. Everywhere else a good solid 10!

I may have paid a tad over the odds for an immaculate copy (£180). But I thought this, I have a great AF lens that works great on both my DSLR's and Film. so in some ways I get two lenses in one. Plus this lens is as rare as hens teeth on the pre owned market!
it is a great addition to my little Pentax prime family (21mm, 35mm, 40mm, 50mm and 55mm) and I have only had it a day.......

Edit.
I used it a lot on a trip to Estonia. I went there only using the aformentioned primes.
Boy does it hold its own against more modern lenses.

Edit (May 2016)
i have used this a few times on the K-1 and it shines and then some! Hence why I have now given it a 10

Examples are here.

Pros: great FOV, sharp, great colors
Cons: plasticky build

I'm amazed that this little gem sells for the price it does, considering what its big brother the FA 31 goes for. I have always loved the ~40-45mm FOV on film, and this lens just feels "right" on APS-C. Do I wish it was a 1.8 instead of a 2.8? Sure, but then I couldn't afford it. I love that I can shoot it as a normal FOV lens on the K5, but switch it over to the LX without missing a beat. There is no 9.5, so 10 it is. The cost to IQ ratio alone justifies the rating.

Edit: after many years of use, I finally sold it on. I lucked into a good deal on an FA20-35/4, and after that this one just sat in the bag. Other than the f4 vs f2.8, the FA20-35/4 gives up nothing to the F28. Both are excellent.

Pros: color, sharp, quik
Cons: none

it's a nice lens. and the color of its pictures are also amazing. someone always compared this F28 with FA28, and said this one was less sharp than FA28, because of lack AL glass. Though I haven't got FA28, the F28 is very sharp even in wide open (f2.8).

Pros: sharpness, bokeh, color
Cons: none

I use this lens mostly on digital. This has got to be one of the classics. This focal length is just right on digital as a true normal lens, in my opinion, because I really enjoyed FA 43mm Limited on film.

It's quite sharp wide-open. Stopped down to F4, it's super sharp. The color-rendering is lovely, as expected out of F-series.

It may be debatable, in my opinion the relative rareness of this lens makes it a great one to own over similar FA-counterparts, such as FA 28 or FA 35. This also works great as a wide-angle on film.

Pros: sharpness, colors, compactness
Cons: none in my book

I am a fan of the F series lenses, and have been wanting to pick up the 28mm for some time. (I also own the 50 É1.7, 135 É2.8 and 35-70mm) The samples I've seen from this lens on the forum were a major inducement, and inspired some serious LBA. Now that I've had the lens for a few days, I'm happy to report that it lives up to my hopes for it, and more. The colors and rendering are great, and the sharpness has really blown me away as I've looked at a few pictures.

The above photo was cropped, but otherwise un-retouched. Notice how you can see the fine texture of the cloth on his jacket, and that's without sharpening applied.

I'm thrilled with this lens, and recommend it without reservation.

Pros: Sharpness, aperture, size
Cons: manual focus feel, aperture ring can be nudged

I love this lens. I needed a slightly wide normal equivalent with a reasonably wide aperture. This lens seems to fit the bill, and I happened to find one on Ebay. I'd previously used a screwmount 28 f3.5 v1.

The lens - Sharp sharp sharp, especially when stopped down a little. This lens sings around f5.6. The colors are wonderful (though not quite as pleasing to me as my M50 1.7...). This lens is the perfect length for indoor events, some landscapes, and thrives as a city walk-around.

Absolutely recommend.
