Lens Review Date: September 26, 2019 I can recommend this lens: Yes | Price: $135.00 | Rating: 10 

 
Pros: Sharp, excellent contrast, low flare, amazing build
Cons: 5-bladed diaphragm. If I were forced to complain, size and weight too.
Sharpness: 10    Aberrations: 10    Bokeh: 9    Handling: 10    Value: 10    Camera Used: MX, X-T3   

I hold this lens in very high regards. I've tried many old 28mm lenses from many different brands and this is one of the best. Compared to m42, M, and A type Pentax 28mm lenses it's the best in terms of raw optical performance. Sharpness, contrast, and flare control are all at a high level. I would also say its performance is in the realm of Contax Zeiss lenses and is even better in some regards. This lens is getting more expensive every day so don't hesitate, I imagine it will only go up in price as it becomes rarer and more sought after.

Lens Review Date: July 23, 2019 I can recommend this lens: Yes | Price: $70.00 | Rating: 10 

 
Pros: Build quality, sharpness, contrast, colors, aberations
Cons: Bit difficult to focus due the "f3.5 only"
Sharpness: 10    Aberrations: 10    Bokeh: 8    Handling: 9    Value: 10    Camera Used: K1ii   

Everything is said about this lens, sharp and clean images even wide open. Reliable distance scale in case the finder is too dark. I compared this with the DFA 28-105, the K-lens is even sharper overall and noticebly in the corners. Almost no fringing or whatever. Best results between f4 - f8. Balances well on the K1 also.

Lens Review Date: May 4, 2019 I can recommend this lens: Yes | Price: $100.00 | Rating: 9 

 
Pros: Sharpness corner to corner; colors; handling & build quality
Cons: Some field curvature
Sharpness: 9    Aberrations: 9    Bokeh: 7    Handling: 10    Value: 10    Camera Used: Sony A7III   

After all these enthusiastic reviews of this lens who say that it is an ultimate landscape lens I wanted to know what all the fuss is about and got one via Ebay for 100 Euros in very good condition.

First impression: Built like a tank, looks like it was produced yesterday (but in fact it is 42 years old!), looks like it can be used for another 50 years without any problems.

Second impression: Yes, it's very sharp from corner to corner, at least stopped down (but that's what a landscape photographer does anyway, you don't buy a wide angle like that for "bokeh" and stuff). MUCH better than any other 24 oder 28 mm vintage solution I tried up to now. Of course there are 50s or 85s who have significantly higher resolution - but for a wide angle resolution is really good.

But the real shocker were the COLORS.

While with all my other lenses I "pump up" the colors a bit (mostly via vibrance or "camera calibration" in Lightroom) to get a punchy, saturated look, this is actually unnecessary with this lens! Colors are from the start really "life-like" and "pop"! Wonderful, but at the same time natural looking, blues and greens especially. I'm not a "SOOC" guy, but this lens comes near to "capturing how I saw it when I was there".

Flare resistance is very good, shooting into the sun or with the sun just a bit outside the frame is no problem at all.
Also no problems with color fringing. Pentax's coatings seem to be really great.

Only thing is that the lens has some field curvature - if you have something in the corners which is at or near infinity, you can't get it in focus. But in typical image compositions, this is rarely the case anyway. You just have to be aware of it and choose your composition accordingly.

Highly recommended!

Fantasticly sharp manual focus lens. People often talk up old lenses but rarely do they stand up against modern lenses. The Pentax-k is a lens which does. I compared this lens against my Sony FE28 and this lens is sharper.

It's also fantastic for InfraRed photography and has no hot spots even at smaller apertures. The only downside is the time it takes to find one (people tend to keep hold once they have a good copy).

Lens Review Date: February 4, 2019 I can recommend this lens: Yes | Price: $75.00 | Rating: 9 

 
Pros: Very good on FF and finely crafted
Cons: Larger than successors, no aperture link
Sharpness: 9    Aberrations: 9    Bokeh: 9    Handling: 9    Value: 10    Camera Used: K-1, K100D   

The K28/3.5 is probably my best 28mm lens. The others were all nearly perfect on APS-C but were less perfect on FF. This lens is nearly perfect on FF. Even wide open, the IQ is very good and at F5.6-8 it is outstanding if you need sharpness in the corners and almost no CA (a bit of red/blue is visible).

Of course, it's a slow lens; the A28/2.0 is smaller (49mm filter), faster by over 1.5 stops, and supports automatic exposure. However, the trade-offs are generally worth it for this lens.

Cons:
Sharpness: 10    Aberrations: 9    Bokeh: 8    Handling: 10    Value: 10    Camera Used: LX, K2DmD, K3 Prestige Edition   

I bought two lenses for my Super-A Stereo cam, but switched to the 35mm for better 3DView, so i sold one of these beautiful examples - build like a tank and very pleasing look on digital makes it a pleasure to work with … even for professional purposes it is still in my bag for the punchy pictures .
I also own a very sharp M 28 f2,8 and f3,5 and the rar K 28 f 2 …
All of them have their own look and handling , but the K28 f3,5 I use the most .
Highly recomended !

Pros: Sharpness Weight
Cons: Focal Length
Sharpness: 10    Aberrations: 7    Bokeh: 7    Handling: 9    Value: 10    Camera Used: K5 IIs, K1   

I bought it used when am using K5 iis. I have 12-24 so i sparingly used this lens. But, i can clearly distinguish pictures from this lens.. they have a unique touch to them. Pictures are sharp edge to edge. Upon, buying K1 i am left with no good wide lens. So, K28 became my only wide lens and it didnt disappoint. Below are two sample pictures from my recent trip.



This was shot wide open.. so it isnt sharp around corners.. also, its not a stacked image but a 30'sec long exposure shot.

Pros: Corner sharpness, smooth focus ring, beautiful for landscape
Cons: none
Sharpness: 9    Aberrations: 9    Bokeh: 8    Handling: 10    Value: 10    Camera Used: K-1   

One of the finest Pentax lenses available and it shines on the K-1. No, you don't have modern coatings and no you don't have Lightroom correction profiles for it, but it is good enough as is. This is going to sound a bit odd, but it is a lens that (more than any other I've shot with) really rewards good photography and is unforgiving with the converse. Sometimes you can "fake it" in post by boosting colors or contrast if your scene was not particularly dynamic or interesting... not with this guy. That is why I thought it was a dud on my first outing with it. On my second, it was quite a different story... some dynamically lit scenes it brought out the deep colors and contrast that it is capable of.

Here's some of my favorites taken with it:

Pros: Colors and sharpness from edge to edge
Cons: Green buton mesuring
Sharpness: 10    Aberrations: 10    Bokeh: 7    Handling: 9    Value: 10    Camera Used: K1   

Mine is mint copy
At F8 to F11 i have no 28mm Lens with such sharpness on borders and extrême corners. My kit zoom D-FA 28-105mm , wich i find no so bad at 28mm f8 , looks blurry when you make comparaison side by side on corners... this prime is razor Sharp on extrêmes.
Bokeh i dont care, this is not build as a fast Lens.
This is The Lens for landscape / infinity
Extrême corners and edges are such Sharp
Color rendering is really good and contrast
Build like all K
Manuel Focusing no problem with K1
I do recommended this Lens , it s quite cheap for the optical quality.
The Best Pentax 28mm prime choice for landscape at the moment

Lens Review Date: December 3, 2017 I can recommend this lens: Yes | Price: N/A | Rating: 10 

 
Pros: Bokeh & close focus possible, sharp enough
Cons: None really for a 28mm

Bonjour,

After using this lens for the month of November 2017 as my Single Challenges lens, I can say that this is now my favorite go-to lens in 28mm ... a lot can be done with this lens if you experiment a bit outside of the usual "envelope" of use for a 28mm lens.

Below are a few images on K-1 and my flickr album for this lens is here : https://www.flickr.com/photos/139020494@N02/albums/72157690127443416

The last image was hastily taken with a n° 1 Pentax K-mount extension tube ... a macro 28 ... Cheers, J

I won the lottery when I found this lens in prestine, unused condition at a local camera store.
Someone must have done a wholesale dump of their manual lenses, as I also found (in unused condition) a K 55 2.0 and an M 50 1.7.
The whole lot cost $120 CDN. including taxes. The part of me that's Scottish was very pleased
This is now my most treasured lens. Slap another name on it and it's a $400 piece of equipment.

Pros: Excellent color rendering and contrast even wide open.
Cons: Relative slow F3.5
Sharpness: 10    Aberrations: 9    Bokeh: 8    Handling: 10    Value: 10    Camera Used: Fujifilm X-E1   

The SMC Pentax-K 28mm F3.5 is not so well-known comparing to its cousins Pentax 28mm from the M and A series but the performance is really impressive. I have been using a handful of semi-wide angle Pentax-A (and M) 24mm - 28mm lenses over the years. The performances of these lenses are quite good (don't get me wrong) but never reach the level of this K 28mm F3.5.

Don't let the F3.5 fools you. Color rendering and contrast are spot on (strong) even wide open.
Bokeh is of course not its strongest but that is normal for a 28mm wide angle lens.
Photo is exported from LR as Adobe Standard (instead of Velvia/Vivid as shot by Fujifilm X-E1) to keep the colors as neutral as possible. No other changes made!
Photo taken with Fujifilm X-E1 with metal lens hood. ISO-200, F/3.5, 1/250s and handheld.

I got this lens as part of a Pentax KX 35mm film camera with Pentax K 55mm F1.8 and paid € 75 for the lot, hence the estimated price $30.

Pros: Colour, Clarity, Sharpness
Cons: none
Sharpness: 9    Aberrations: 10    Bokeh: 9    Handling: 10    Value: 10    Camera Used: Pentax K-5IIs   

I got into Pentax without knowing exactly what was this brand about. I just wanted to use that old SMC M 50mm f2 that was at home, completely forgotten, inside a old paper-box.

After some time trying other Pentax and third-brand lenses I managed to get the K28/3.5 and I was extremely shocked with the results. It was not about the sharpness, which was quite respectable, but the colour and the contrast of the lens. It is particularly on the blues and greens where I think this lens excels. The way this lens renders light makes the images very pleasing. It is hard to find the words, but I would say that the K28/3.5 delivers some sort of "clarity" or "magic" which converted me instantaneously into the Pentax fan-club. After I used this lens I understood what was Pentax about and what some people meant about Pentax colours and that stuff. The way this lens renders colours I believe it is not easily obtained in edition.

I would have never thought that a ƒ3.5 wide angle would become my favourite lens in my collection, but it certainly did. It also behaves great on a Sony A7 and I hope some day to try it on a Pentax K-1.

Pros: Cheap; Very sharp for intended usage; good size; well made; good flare tolerance
Cons: none
Sharpness: 10    Aberrations: 9    Bokeh: 7    Handling: 10    Value: 10    Camera Used: K1; A7k   

This is the best 28mm for infinity focus stopped down shooting on the FF K1 (and A7) for the price.

Don't let the f3.5 distract you away from this lens.
It was designed for a purpose.
Landscapes.


Sharp to the edges at f8-f11 that many faster 28mm can't match.
Flare tolerant as well.
At an incredible price too.

If you are looking for a do it all 28mm or a wide for isolation shallow DOF look (an oxymoron imo), look elsewhere and probably spend more.
If you are looking for a great landscape lens, this is the one.

Lens Review Date: June 14, 2016 I can recommend this lens: Yes | Price: $190.00 | Rating: 9 

 
Pros: Light, well built, smooth focusing
Cons: Horrible vignetting at 3.5 on K1
Sharpness: 9    Aberrations: 9    Bokeh: 9    Handling: 10    Value: 10    Camera Used: Pentax K1   

Today I tried out my new-to-me, $190 SMC PENTAX 28mm f/3.5 on my K1 camera.

My testing resulted in the following observations:

1. Lots of vignetting at f/3.5. Gone by f/4
2. Its' sweet spot is f/11 - f/13.
3. Good and sharp, however I have to admit that the much more expensive Sigma Art lenses and Zeiss ZK lenses are a tiny bit sharper (I know because I've previously owned them).
3. Beautiful Pentax colors.
4. Distortion is insignificant

I really like the 24mm and 28mm field of view. I'm quite pleased with this inexpensive little lens. It will easily get me by until Pentax/Sigma/Zeiss some day offer a new premium lens in this range.
