Lens looks great - like a modern-day Sigma.

Performance is dire. A handsome paperweight.

Maybe mine is a particularly bad copy?

Definitely can't recommend on this experience.

Lens Review Date: September 5, 2020 I can recommend this lens: Yes | Price: $20.00 | Rating: 8 

Pros: Cheap, easy to replace
Cons: A consumer lens (budget lens)
Sharpness: 8    Aberrations: 7    Bokeh: 8    Handling: 9    Value: 10    Camera Used: Nikon N70 and Pentax KP. K10D    Autofocus: 7    New Or Used: Used   

The Sigma 28-80 Aspherical (macro) lens has been around for some time. This cheap alternative to name brand kit lenses made this lens extremely popular back in the later era of the film days. I bought this lens for my Nikon N70 simply due to price point. I saved a bundle with the Sigma when compared to the cheapest Nikon alternative at the time (Nikon 35-70 3.3 AF). I found the Sigma usable for most applications. I may have gave up a bit of sharpness when compared to the Nikon, but not enough to concern me. I found the Sigma contrasty enough, sharp enough, light weight, small, and easy to handle. This lens didn't set the world on fire by any means, but it was far from being a down-right dog. This lens has found itís way onto my Pentax KP, and I find I still have the same feelings about this lens as I did when using it back in the film days. The price point canít be beat, this lens will give you a fair amount of keepers, and the lens is extremely easy to find on eBay. Will this lens blow you away? NO! Will this lens prove to be sharp as a tack? NO! But it will be sharp enough and you can do wonders with most images in post-processing.

This lens is for those on a budget looking to grab some keepers on the cheap. You donít have to be overly protective of this lens due to the price point. This Sigma is easily replaceable. This lens was produced by the thousands, probably one of the highest selling Sigma lenses they ever produced.

Bottom line: Good enough for those on a budget

Some samples from Pentax KP at 50mm:

Lens Review Date: April 25, 2019 I can recommend this lens: No | Price: $17.00 | Rating: 6 

Pros: Light weight, fast AF, macro
Cons: Color rendition, bokeh, contrast
Sharpness: 7    Aberrations: 8    Bokeh: 5    Handling: 9    Value: 7    Camera Used: Pentax K-30    Autofocus: 9    New Or Used: Used   

I received this lens bundled with a used KS-2 so my $17 cost is an estimate.
The other reviewers must have received a much better copy of this lens than I did.
Other than light weight, decent build quality and fast autofocus, I canít find much to like here.

The lens I have looks like new and is clean inside and out. Surprising contrast, color rendition and sharpness are not good at 28mm. Some improvement is visible by 35mm to around 70mm, then it goes bad again. The macro mode at 85mm gets you in close, but the sharpness and contrast delivered by my sample makes me glad I own other options.

I definitely do not recommend this lens.

Lens Review Date: November 27, 2018 I can recommend this lens: Yes | Price: $10.00 | Rating: 8 

Pros: Light weight, Very sharp, nice colors, fast and fairely quiet AF, inexpensive, good macro
Cons: None, for that price
Sharpness: 9    Aberrations: 8    Bokeh: 8    Handling: 7    Value: 10    Camera Used: Nikon D600    Autofocus: 9    New Or Used: New   

Picked up a used one in eccellent conditions on ebay, for $9.99, wasn't expect much for that price, but i was wrong.
Boy this lens is sharp! Has a fast and fairely quiet AF, the color rendering is slightly off, but in a nice way (saturated a d on the dark side).
Very versatile zoom range, the macro function is pretty good.
Overall, in my modest opinion, a great lens, expecially for the value.

Lens Review Date: November 5, 2018 I can recommend this lens: Yes | Price: $20.00 | Rating: 8 

Pros: price, image quality
Sharpness: 8    Aberrations: 8    Bokeh: 8    Handling: 9    Value: 10    Camera Used: K-1    Autofocus: 9    New Or Used: Used   

I bought this lens a number of years ago, to test if it was my camera or my only lens which was broken. This was the cheapest autofocus lens I could find on eBay. It turned out that the camera's autofocus was broken. I occasionally used this lens with different crop cameras until I kind of forgot it for a couple of years (as the focal length range is not ideal for APS-C sensor). When using it, I always thought the pictures were rather okay.

Now, come 2018, I decided to test this with K-1. Surprisingly, it turns out this lens is actually pretty good. I did not do any systematical testing with different apertures etc. and it is very much possible, even likely, that it is not very sharp wide open etc. Last weekend, I went for a hike with this lens + K-1 and I am extremely surprised at the images it produces. Based on this half day of shooting, I am ready to give a rather positive feedback to this lens. It may be cheap, but that is probably because there are so many of these around. Again, it is maybe not super sharp, but the results are okay. IMHO, the difference to DFA 24-70 is not nearly as big as the price difference would suggest.

I will definitely try to take out this lens in some better light some day to see if my impression holds.

Lens Review Date: December 27, 2016 I can recommend this lens: Yes | Price: $30.00 | Rating: 7 

Pros: Lightweight, nice handling
Cons: Macro/Normal switch sticks sometimes
Sharpness: 6    Aberrations: 7    Bokeh: 6    Handling: 7    Value: 7    Camera Used: K2000, K100D, K10D, K30    Autofocus: 7    New Or Used: New   

I've had this lens for about a year and a half and I mainly use it to photograph small items for eBay listings. It works okay for that purpose but it's not my all-time favorite lens. It has recently developed an annoying habit of not wanting to switch out of Macro mode. The little switch sticks, which locks the zoom at 80mm. To fix it, I have to remove the lens from the camera and jiggle the aperture tab on the base. It will then release, albeit sometimes reluctantly. Fortunately, I have a couple of other lenses that cover the same focal range, so it's no biggie to leave this one in Macro mode.

UPDATE: I have discovered that quirk with the Normal/Macro switch only manifested itself on my K100D. I have not had that problem at all using this lens on my K10D and K30.

ANOTHER UPDATE: The sticky switch has gotten worse recently so I've stopped using it into macro mode and the lens overall sees increasingly less time on a camera.

I really enjoy this lens. I find it to be sharp and well made. I have the metal mount so i think this makes it more sturdy. Its fast to focus and produces sharp images. Macro mode is useful. Used on my Kx.

Lens Review Date: March 25, 2012 I can recommend this lens: Yes | Price: $25.00 | Rating: 8 

Pros: Macro, Decent Sharpness
Cons: Plastic Mount
Sharpness: 7    Aberrations: 8    Bokeh: 7    Handling: 8    Value: 8   

I have the version II lens with the plastic mount. For me the best thing about this lens is the macro feature. I've taken some images I am very pleased with using this feature. It is ok as a normal lens if stopped down to f/8 or more. See an example at the link below.

Lens Review Date: June 3, 2011 I can recommend this lens: Yes | Price: $20.00 | Rating: 8 

Pros: Metal Mount, 1:2 Macro, cheap, sturdy
Cons: difficult to access the pin to move from A to using the Aperture ring with lens on the camera but you would rarely want to - leave it on A.

I haven't had much time to play with this lens but, so far, for the price it is a bargain.
This is an older style of lens with an Aperture ring and DOF scale around the focusing ring but works great when set on A and has Auto-Focus (unlike much older M or A lenses).
The lens is sturdy and has a great feel.
Manual focusing can be a bit touchy.
The range makes it a good walk-around lens with a handy Macro function at 80 mm depending on what type of shots you usually take.
Make sure it's set to 80 mm before trying to flick the Macro button. Leave it on A when using M mode unless you want to use stop-down metering.
For the price you can pick these up they are great value over many older M or A lenses.

Lens Review Date: December 11, 2010 I can recommend this lens: No | Price: None indicated | Rating: 7 

Pros: Metal mount, relatively cheap, lightweight, very good Macro
Cons: Poor focusing at distance, rotates when focusing,

I used this lense in a PF challenge (SiS), and found it to be an excellent macro lense, but for normal portrait use, very difficult to use.

There is little room for error when focusing, as there is only ... say, 15 degrees to play with, which in lower apertures led to some "not pretty stuff!". However Macro mode was quite crisp, and produced fine results.

The lense I'm reviewing here is almost identical to this in every respect, except that the rubber focusing ring has shorter grips (S/N 3429160) , not the wider version shown here.

In short, a good lense close up, but not a good general purpose I would think. If you want a Macro with other abilities, it's OK, but otherwise, buy a purpose built lense!

Lens Review Date: October 24, 2010 I can recommend this lens: Yes | Price: $1.00 | Rating: 10 

Pros: Metal lens mount, 28mm wide angle, great for macro photography
Cons: None

I have the version of this lens with the metal mount and mine is in a gold like color. I'm a big fan of wide-angle lenses and 28-80mm is a nice zoom range.

What I like best is it's great for doing macro shots at 80mm (there's a dedicated macro switch on the lens)-it is nice and sharp at 80mm and in between, plus I find the zoom ring has a nice feel to it and focusing is quite easy .

Build quality is quite nice for one that's made out of plastic.

Lens Review Date: May 20, 2010 I can recommend this lens: Yes | Price: $20.00 | Rating: 8 

Pros: Sharp , Fast autofocus , Light
Cons: F3.5-5.6 a bit slow

I own the version with a metal mount , but without the macro mode. In my opinion it is sharper than the FA 28-70. I like it a lot , and for the price you can find it there is no alternative which would be that good.

Here is an example of how sharp this lens can be. Only White balance correction has been applied.

Lens Review Date: November 9, 2009 I can recommend this lens: Yes | Price: $20.00 | Rating: 7 

Pros: sharp for cheap zoom, well built
Cons: color not as good as later version

This is not as much of a review as it is a clarification of different Sigma 28-80 f3.5-5.6 lens versions.

A couple of reviews above this, Steve mentions that he has the II version, I do to and have added a separate listing for it. BUT, I also have another version of this one, which came with another package I bought on ebay. The one I have does have a metal mount and it has 8 blades, just like the II. The "grips" on the barrel are like the II. Here is the strange part that I just noticed, this one focuses in the opposite rotation of the one pictured above and the II. I have posted a picture here for comparison, notice the focus ring markings going the opposite direction.

The lens is not a bad lens, but it's not as good as the II, at least in my copies.

Lens Review Date: September 19, 2009 I can recommend this lens: Yes | Price: $45.00 | Rating: 5 

Pros: Cheap Price, Fast Focus, Sharp within limits
Cons: CA is hit/miss, feels cheap, plastic mount.

I liked this lens so much as a cheap, "who cares," walk-around that I purchased another when the first met with an unfortunate accident. I've gotten some great images from this lens, even indoors with an AF500FTZ flash mounted on a GX-10 (now that's improvising).

I think this is one of the last Asphericals Sigma made for film and despite that, it seems to make the digital transition quite well.

Lens Review Date: August 1, 2009 I can recommend this lens: Yes | Price: $18.00 | Rating: 10 

Pros: Great IQ, fast AF, cheap enough to knock around
Cons: somewhat slow maximum aperture

Edit: It has just come to my attention that I have the "II" version of this lens, and the optics might be slightly improved over the first version.

I cannot believe that people keep giving this lens such a low rating. My 10 is at this point artificially high (should be a 9) to offset the unreasonably low numbers from other reviews.

The cons are a slow maximum aperture, a front element that rotates, a poorly designed hood mount, and a plastic mount. This list of cons applies to a lens that usually sells for $20-$60. Can you really list these at faults at this price? This lens is sharp, focuses FAST, is compact, and is very light. If Pentax rebadged this lens as their own, and sold it for twice as much, it would get 10's across the board for quality and value. I have personally compared it to the Takumar-F 28-80. The only two areas where the Takumar has a minor edge is in bokeh and build quality. In every other possible way the Sigma wins.
