Third-Party Pentax Lenses
Mitakon 28mm F2.8 MC

Review Date: December 16, 2024 Recommended | Price: $2.50 | Rating: 8
Pros: Inexpensive, mechanically excellent & good IQ when clean
Cons: Curved plane of focus
Sharpness: 8 Aberrations: 7 Bokeh: 6 Handling: 8 Value: 9 Camera Used: P30 film; APS digital
Here's another inexpensive 1980s lens with all its expected attribute and issues.
I paid £1.99 GBP, about $2.50 in November 2024 on UK eBay. The rubber lens focus grip was missing - but I took one off an old dud lens and it now looks great.
Testing on a chart, you find:
central sharpness and softer edges and minor vignetting wide open that improves as the aperture closes
accentuated by field curvature
with some minor barrel distortion -
And because there are no floating elements, close focus is only 35cm, or about 12 inches.
i.e. near everything you could predict to find out about 3rd party wideangle lenses from that era. In real life, this matters far less unless you are doing architectural photography, as if I want to photograph a flat object at near distances for edge-to-edge sharpness I will use a 50mm lens (ideally my 55mm macro) held rigid.
In addition, because there is probably no high-density glass or asymmetric lens elements there is chromatic aberration in the corners with high contrast subjects.
Almost none of this is visible as a problem when the lens is used for its likely design spec' - printing 6x4 - 7x5 prints from 35mm negative film or 35mm transparencies to show at home with a projector. Today that also includes viewing with no or only minor crops on a laptop screen or tablet computer.
As with all these type wide angles used on digital cameras, the rear lens group is critical to get clean; the relative diameter is small compared with the front element, and the usual retro focus design means that the rear lens element surface is close to the sensor and can reflect light back. Near all these lenses have a rear group that is easy to remove if you have a spanning wrench - and can be cleaned with alcohol. Even the "clean" looking lenses I have had from this 1980s era improve as it seems near all have at least a thin film of haze laid down from vaporized lubricants in the lens. Just know how to test for decentering when you put it back together.
The lens is multicoated - Mitake sometimes called it "pleuricoated" - but on APS, as there is a rim of unused lens outside the "crop" that can contribute to veiling flare, scattering out of image light from bright areas by internal reflection into the "within image" areas, so fitting a lens hood and or shading out bright light sources "out of frame" is important to get the best contrast and performance.
Reading reviews on other sites gives this lens an often bad reputation - but I have seen my old lenses jump from very poor to good just with the rear element cleaning, so I suspect there is a lot of batch-to-batch variation. Also, in this era of excellent lens coatings we forget why lens hoods were considered "essential" in the past. Veiling flare on crop sensor cameras is often overlooked as you compose - precisely because you can't see potential bright areas in the out of area "full frame" image through the crop-sensor viewfinder!
For the price I paid (less than a caffe latte) I'm more than pleased with my copy - which is very smooth to use. It doesn't do anything on digital cameras that a kit zoom can't do - but it does keep my manual film camera skills in practice and keeps me away from setting the camera to "P" mode !!!

Pros: nearly perfect sharpness Cons: unfortunately CAs
Sharpness: 10 Aberrations: 5 Bokeh: 7 Handling: 9 Value: 7 Camera Used: k-5
For such an expensive lens I expect best correction of CAs. But as the majority of the modern lenses, it disappoints me concerning this point of view, too. Coloured fringings are visible.
It seems, that the lens manufacturer are presuming, that all RAW photographers make thei workflow after shooting with PhSh LIGHTROOM, in order to correct CAs. This is foolish.
Indeed for a wide angle zoom, it is nearly razor sharp, stopped down a few.
+++ excellent sharpness
+/O bokeh okay, not blowing away, but okay
O CAs sometimes visible
+ good colour rendition
++ high contrast
this is a good lens
Sometimes it suffers of AF precision -reports my son.
recommendation yes - but I'd lent it from my son - not my favorite because of visible CAs on big magnifications. My darker FUJINON 16-50 seems to me better corrected.
Comment of the Week:
Pentaxian reh321 on What was your most used camera in 2024? I started this year using an “ME” with color film and a “Super Program” with B&W film, but I ‘ve taken more photos with the “17” I got on June 17th than with any other camera, and next year I’ll have a Grand-daughter to follow around {even then I expect to photograph Squirrels with an SLR, but I anticipate her being more interesting}.
