Vivitar (Komine 28xxxxx) 28mm f/2.8 Close Focus

This review page is specifically for the Vivitar 28mm f2.8 Komine made PK/PKA versions labelled "close focus".
Vivitar 28mm wide angle lenses were made primarily initially by Kino Optical (Kiron), and Komine. There is a plethora of different versions see link below. The kiron versions have serials 22xxxxx, the Komines have 28xxxxx serial numbers.

T4/TX tokina made (37xxxx) 28mm listed here.

Kiron versions, early T-mount versions, later versions by Tokina (37xxxxx) and Cosina (9xxxxxx) need/have a separate listing.

The Kiron ones are known to suffer from oily/sticky iris blades. There is info on how to clean here.

There are a large number of vivitar 28mm variants. They are listed in this blog.

Lens Review Date: July 23, 2021 I can recommend this lens: Yes | Price: None indicated | Rating: 7 

Pros: It takes nice images
Cons: Too hyped up
Sharpness: 7    Aberrations: 7    Bokeh: 7    Handling: 10    Value: 8    Camera Used: Numerous   

You'll notice that many people are pushing this lens without really concerning themselves with variables between many "Komine" versions starting with 28+++++ across the years. You'll also find that there are numerous non-28+++++ versions that make your choices even more difficult to make accurately. Let's just focus on the 28++++ versions. Read the link in the introduction and do some realistic homework from the blog link there. You may well get confused and simply let your enthusiasm make a random choice before buying. Beware before you hand over your cash.

The 28+++++ version is often cited with "close focus" around the rim of the lens being one of the best 28++++ versions. This is why ebay sellers force the price up for that lens. Once you buy it at inflated price check the image quality to a Pentax f2.8 28mm lens (avoiding the short barrel version), a Takumar 28mm lens, a Zeiss Flektogon 35mm lens and really wonder if this Vivitar lens is as good. If you have a clean and clear version it may equal the Pentax 28mm. It won't equal the others. As a cheaper alternative to the remaining two lenses, it'll give you nice pictures, but you'll find variable quality across the f-stop range with some blur around the edges on all. f8 and f11 give the finest pictures, as you'll find with a lot of old 28mm and 35mm lenses from the 1960's to 1990's.

Just don't expect anything dazzling, unless you are the kind of person who "makes perfection" in a software package.

All all the 28+++++ lens has some nice versions to offer that'll take some all right pictures.

Pros: Capable, Close focus, price and availability

Plus points to consider:

In actual use:
In the field with a Pentax dSLR, the usual practices/tricks for stop-down metering with a Pentax-K/M mount lens apply. With 35mm film there are no hidden gotcha's other than maybe the small form factor. I use this lens on both film and APS-C digital.

Lens Review Date: July 28, 2019 I can recommend this lens: Yes | Price: $23.00 | Rating: 10 

Pros: Price-Performance-Close Focus
Cons: Will flare in direct light
Sharpness: 10    Aberrations: 10    Bokeh: 8    Handling: 8    Value: 10    Camera Used: K01   

This is for the "K05" variant (see link in description above)

Everything you could want in a low-cost lens. I even used it on my Q7 where it looked good wide-open. No purple fringing, good contrast. Shooting into the sun I did manage to get some flaring, as to be expected for a 40 year old lens design.

Lens Review Date: April 29, 2019 I can recommend this lens: Yes | Price: $28.00 | Rating: 10 

Pros: Cost, Sharpness, Construction
Cons: None (for a manual focus lens of this era)
Sharpness: 10    Aberrations: 9    Bokeh: 9    Handling: 10    Value: 10    Camera Used: K1000   

My copy is Komine (28xxxxx) Close Focus PKA version marketed as an RL Edition (basically 7 year warranty rather than the usual five... kind of a moot point now). It's a great manual focus lens for this era.

It's a bit soft wide open but really quite sharp as you stop down. Here's two examples, both shot with a k1000 and Kodak Gold 200 film.

For this long exposure of a highway overpass, I had the lens stopped all the way down to f16. You can see 6 pointed sun stars on some of the brighter street lamps. Looking at the lines from the roads, you can see the distortion is pretty minimal.

For this night street shot, I was shooting handheld, so it was wide open at f2.8 at 1/30s. The slight blur around people was due to movement and the slower shutter speed. However, looking at the buildings, they're not bad even wide open.

In sum, I paid less than $30 for the lens and it's easily one of my favorites. A great deal, definitely worth picking up if you see one.

Lens Review Date: February 13, 2017 I can recommend this lens: Yes | Price: $35.00 | Rating: 9 

Pros: sharp, solid, lightweight
Cons: some flaring (which is a pro for my use), manual
Sharpness: 9    Aberrations: 8    Bokeh: 8    Handling: 10    Value: 10    Camera Used: K5   

My first PK/A lens, and I love it. Results are sharp, no visible CA, some flaring (see below) but for my use this is a bonus and gives it character.

Solidly built, fast and smooth action, aperture control and other modes work beautifully in my K5, though I tend to prefer manual settings. Works well in dark and daylight, and I suspect thisíll be my go-to manual lens for some time.

Ridiculously affordable, and worth every penny. From other reviews, the PK/A is version to get, and I concur.

Lens Review Date: May 8, 2016 I can recommend this lens: Yes | Price: $60.00 | Rating: 9 

Pros: sharp, light, nice price.
Cons: n/a
Sharpness: 9    Aberrations: 8    Bokeh: 8    Handling: 10    Value: 10    Camera Used: Canon/Sony   

Again, this is a manual, old lens and apparently not everyone knows how to use manual controlled lenses.
I did not use it for close up shots much but it is a very nice feature to have.
Even wide open the lens is very decent, stopped down it is very good.
Here is an example how it performs:

It is a very good lens, learn how to shoot manual, do not read DP Review forums and you'll good.

I would recommend this lens.

Thank you.

Lens Review Date: May 7, 2016 I can recommend this lens: Yes | Price: None indicated | Rating: 9 

Pros: Close focus, colours on Pentax, good for extension tubes, 49mm filters for legacy Pentaxians.
Cons: Best used only for close up and macro. Just OK with landscapes.
Sharpness: 8    Aberrations: 7    Bokeh: 8    Handling: 8    Value: 10    Camera Used: K30   

My first review here. Mine is the MC screw version and kiron version serial number starting 28........

I bought this as part of a job lot and this was the only useful item and luckily justified the purchase of the other garbage

In quick comparison to a Pentax-A 28mm prime for general purpose mines didn't handle as well or match it for infinity photography such as landscapes. It was also more prone to flare however if you read what it says on the front of the lens, "Close Focus", and use it for that purpose you will be well pleased and especially with the Bokeh but only for close up purposes again.

The photo below is with approx 50mm of extension tubes, all being manual with no facility for the camera to stop down the lens means focusing to-and-fro at f16 (max aperture on this lens). It is very difficult to achieve exacting critical focus with this method, and to get the greenfly (just behind critical focus), grass blade and front section of nectar in one plane was a tall order hand held.

Check out the colours from this little gem straight from the K30 without any PP whatsoever.

Lens Review Date: July 31, 2015 I can recommend this lens: Yes | Price: $60.00 | Rating: 8 

Pros: Close focus, half stop aperture ring, smooth focusing
Cons: Slight CA, long focus ring throw, slow, flare

I picked this up going by previous reviews and would - for the most part - agree with them. It's a good fit for APS-C as a normal lens, and with a nice close focusing ability (1:5 ratio on mine) is pretty versatile. By these virtues it was my lens of choice for most of my last holiday in France, though not as sharp or colourful as my Petri 50mm F2.0, nor of course having the range of my DA 18-55. I've used it to good success for close-up photos of butterflies and flowers, a bit further out for some environmental portraits, and also for a spot of landscape though I never really hit my stride there. Whilst it spent most of its time on the K-30, I also used it on an MX with Velvia 50 slide film, though the latter is yet to be developed.

The sharpness is pretty solid for the most part, though as has been mentioned previously it is noticeably soft wide open. Corner sharpness peaks at F5.6-8, whilst centre sharpness has a slightly wider range at F4-8. This is really to be expected. Vignetting is only really significant wide-open. Chromatic aberrations are often there, even when you're not trying to push the contrast. They're clean and small, so usually easy enough to tidy up in PP, but you can lose some sharpness if you don't look out for them.

The focus and aperture rings both work well, though I found the former to have longer throw than I would have liked. When you're trying to switch from distance work to something close that you've just spotted, you might end up missing it on occasion.

Something that bugged me about this lens, and I don't know if it's just my copy, but I could swear it's dark, as in I actually lose a stop with it. Example: I took a photo of a mountain at F8 with this lens, but felt that it really could have done with being a bit tighter so switched to my 50mm. When chimping that shot I found it to be overexposed where the Vivitar wasn't. I haven't done anything resembling a scientific test of this, so take this anecdote with a pinch of salt.

Overall I'd probably recommend this lens if you're looking for a relatively cheap normal prime for an APS-C body. It hasn't got any spectacular characteristics, but it does have a good focus range and sharpness. If you're so inclined, the out of focus effect can be quite fun to play with as well.

Lens Review Date: August 2, 2013 I can recommend this lens: Yes | Price: $30.00 | Rating: 8 

Pros: Crisp, decent IQ, nice to use
Cons: over 30 variants and big price variations
Sharpness: 8    Aberrations: 7    Bokeh: 7    Handling: 9    Value: 9   

Picked up my little Vivitar 28mm a while ago as I was after a cheap manual focus 28mm to tinker with for Panoramas on digital. The ebay pic was fuzzy, I knew it was a Komine but was amazed to get a mint PKA for very little cash

According to the the Robin Parmar listing, my copy is:
A03 "Vivitar | 28MM 1:2.8 | MC | CLOSE FOCUS WIDE ANGLE | NO. 28xxxxxx | ō49MM"

It's great. Really nice to use (just like a Pentax manual focus 'A') works well with my K10D and doesn't seem to have any metering issues. For panoramas and stitched images it works fine (I see no obvious vignetting f4 to f11) and it shows little distortion. It an ugly sort of fella though

Used as a straight 28mm on DSLR (so 42mm equiv) it is a little more limited for me as that isn't a focal length I find useful but it seems capable enough. Pixel peeping there is some CA (easy to fix) and it can be prone to flare outdoors so a hood is a must - being 49mm these are easy to come by, you might already have one

when the opportunity arises I will ad some pics here

I have the Vivitar MC Close Focus Wide Angle Serial#28xxxxxx, Pk-A. A big step above the Pk. I only have two words: Get one.

As good as the f2 version.

Will post images later.

Lens Review Date: July 7, 2011 I can recommend this lens: No | Price: $70.00 | Rating: 6 

Pros: VERY light & thus easy to hand hold, auto aperture, macro
Cons: Not the best IQ from a prime, not wide enough for APS-C

Don't get me wrong on not recommending this lens - I don't think it's hopeless, I'm just not sure of it's relevance in the digital age. It's not wide enough to be a proper landscape/wide lens - but of course has no reach either, and because of its f2.8 combined with a not-long 28mm, it doesn't throw backgrounds out particularly easily.
Positives are that it can focus very close, which is nice so I might recommend it to someone for a nice cheap price who is looking to take close shots of something, but I wouldn't recommend it for landscape or just generally 'street photography', as it's IQ isn't actually that amazing for a prime, personally I think you're better off with a kit 18-55 - but if you're going to buy a lens separately, go one way or the other - either really wide like the 16-45 or Sigma 10-20, or a 50 or 55 prime.

Pros: good value, build

This is a good lens for the money. I have used it reversed for some extreme macros. The build is great. I have not had a chance to use this much after acquiring other lenses in this fl range.
