Hello, everyone.
I have just bought this lens, but will only receive it in September because both the seller and I are on holiday; I have seen that the manual focus version of this lens is uncommon, and I would not have bought an AF for the known problems. The reason I was looking for a bright wide-angle lens is to gain in ISO compared to my zoom lens, also because I often shoot scenes with people moving around, and IS is counterproductive, because it gives you a security that turns out to be detrimental when the only thing sharp are tables and chairs, and human figures become ectoplasm. Being a fairly limited use, the budget was tight, and this seemed like an interesting option, if I was not satisfied I could resell it without serious loss, But the question is if anyone knows this lens, because I found very little on the web. When I get it I will do a small review on these pages,

Sigma and Tamron for that matter made a number of their autofocus lenses (roughly 1985-1999) in manual focus counterparts, often identical in appearance. I'm not sure how they handle differently, I'm sure old reviews would tell you.
Maybe this lens being labelled "MANUAL FOCUS" is a little more literal than I've seen before though.
Sigma made a 28mm f1.8 high speed wide in the mid 1980s, I'm sure this Mark II performs a tad better in some regard. The markings are clearly 1990s Sigma, maybe towards the end of the decade?
The change in appearance from early 1990s to late 1990s Sigma lenses was not always consistent in my experience. _________________ UK |

Judging from the marks on the barrel and partially rubbed-off lettering, this lens may be finished in their dreaded "ZEN" soft-touch coating. Hopefully it isn't, otherwise it may be a very sticky lens to the touch...
If it has the soft-touch ZEN coating, that finish can be rubbed off with IPA (isopropyl alcohol), but you would lose all the markings as they are screen-printed on top of the deteriorating ZEN coating _________________ Mark

As far as historical information is concerned, I actually found all the details: https://lens-db.com/sigma-mf-28mm-f18-aspherical-ii-zen-1994/ It is the ZEN series, if necessary I don't mind losing the lettering, but the seller claims it is not sticky. What I couldn't find was any information or pictures on the performance of this lens |

Thank you, that does not bother me too much since I don't plan an heavy use; glad to know that you were pleased with the pictures. |

Yes, and probably a fun lens to play with, considering the shallow DOF/ wide angle combination. |

Indeed. I have to say that in the past I used to have many (and way better) similar lenses: Leica Summilux 35/1,4 (both aspherical and not), Canon L 24 and 35 1,4, and so on. But it was another life, and photographers were a little richer
With the same specific I also had the Canon 28/1,8, a mixed bag really; now we will test this Sigma, for 100 euros I don't have too high expectations, wich is the secret of happiness, I guess... |

I am a manual focus user through and through, and had bought the regular AF version of this very lens cheaply a few years ago, with the intention of using it purely manually. The focus grip was a bit too small, which seems nicely remedied in your MF version. Everything else, including the aperture ring, was smooth and lovely to handle. And the image quality astonished me (positively, and not just for being a Sigma), even wide open on a 4o MP FF camera. Performance overall was better than the 7artisans 28/1.4 I had also tested! And I only sold the Sigma, eventually, because it gave such delightful images that I became prepared to spend more money and weight on a fast wide-angle.
I think you'll be very happy _________________ Photography Reference Tables:

Thank you so much!

Christian, I scrolled through your Flickr feed, and let me tell you that you are an extraordinarily creative photographer. |

I finally received the lens. Aside from the infamous ZEN finish (not yet sticky, anyway), it is in excellent shape. The glass performance itself is wonderful, but there is an annoying difference between the left and right sides. I think it is a mechanical problem, because by focusing them independently they show the same sharpness. I have not had time to open it yet, but I suspect that some front side play may be responsible for the problem. Other than that, the rendering is really excellent, and I will post some examples in the next few days. |

A first taste of wide open close up. This lens is really something for a fast cheap wide angle. JPGs straight out of the camera, untouched

Thank you Caspert!
Unluckily I have to say that the front part, all plastic made, does not have the requested steadiness to keep the glass well aligned, so it's impossible to let the glass express its full potential.
I'll show later the amount of the issue when it comes to architecture. |

As promised, below are the tests in the landscape and architectural subjects.
the following images range from f:1.8 to f:11; as you can see the left side of the photo is much sharper than the right; if I press the front of the lens hard enough, forcing on some elasticity, the situation improves dramatically. in its normal state, the lens is not usable at the largest apertures for this type of subject.

Following are some shots of three-dimensional subjects taken at full aperture (I know that landscape is not shot at full aperture, but I wanted to simulate the condition I would face if it were nighttime, i.e., the situations for which it makes sense to buy a 28mm f:1.8 ); in this kind of subject the flaw is invisible or barely visible; if you pay attention, you can see that if there are objects closer to the camera on the right, they turn out sharp along with those placed farther away in the center or on the left.

And finally, same subject shot wide open and at f:8

For the kind of use I plan to make of the lens, i.e., events and human subjects, I can live with the flaw, but it is still a pity that a potentially very high optical quality is penalized by a mechanics that is not up to the mark.
All the pics SOOTC!
Thank you for your attention |
