Review 1 of 8

Price Paid:  $100.00 from B&H

Summary:

This was the biggest purchase mistake of my career. I bought this lens to replace a Canon wide zoom I had owned for years. I was on a very tight budget and needed a lens fast.

At 3 feet, the lens focuses well. Anything after 3 feet isn't crisp at all. Like the one reviewer said, you can sharpen the images in the editing process, but no one should have to do that.

As for the other reviewer, who said this lens was great for a beginner, I would say he's wrong, because a beginning photographer would see the fuzzy images and think it's human error.

And, anyone who thinks these images are crisp either needs glasses or isn't zooming in during the editing process.

True, you get what you pay for, but I expected Sigma to turn out a better product, and because of this lens's poor craftsmanship, I will never purchase another Sigma product as long as I live.

I paid $100 for this lens, and it has cost me over $2,000 because of the poor, unsellable shots I've taken with it.

But, if you want it, contact me, and I'll sell it to you for $40.

Strengths:

Inexpensive.

Weaknesses:

Unclear images.

Review 2 of 8

Price Paid:  $0.00 from sigma4less

Summary:

I basically got this lens because it was fast and because the 58mm filter size is the same as the other lens I use (thus no need for stepping rings to use filters). The lens is pretty much what can be expected from a cheap lens, so-so performance but nothing spectacular. My main complaint is that the lens produces noticeably soft images through all apertures and focal lengths. Sharpness can be improved to acceptable levels in post processing. It is good enough and does what I need (and fits my *very* restricted budget), but if you can I would save up some cash and go for something better.

Strengths:

Fast, compact.

Weaknesses:

Soft throughout all apertures, in fact it is softer than the lens of my P/S digital camera!

Review 3 of 8

Price Paid:  $80.00 from www.BHPhoto.com

Summary:

I needed a lens to replace my kit lens on my Nikon N65, so I bought this one. I've been very happy with it while I used it. I ended up replacing it with the 28-70 2.8 lens, and using this one as a backup. This lens still gets used when I and a buddy are out shooting and we both want a semi-wide angle lens.

Strengths:

Sharp, low cost, lightweight

Weaknesses:

Body has a plasticy feel, almost like it was a toy

Similar Products Used:

Nikon 28-70G Sigma 28-70 F2.8

Customer Service:

Never had to use it

Review 4 of 8

Price Paid:  $70.00 from EBay New

Summary:

I bought this to have a lens that I wouldn't care much if it got ruined in rough use. I got what I wanted... I don't care. In fact it would probably be a blessing. Great idea in a lens though. Fast, inexpensive, good zoom range, what more could you want? How about quality. I guess I got one of the better ones as mine has the metal mount for Canon ef. Here is the skinny. Auto focus is OK. The motor is not too loud and it isn't too slow either. While around the middle focal lengths are OK wide angle and telephoto are very soft. Stopping down helps some but why have a 2.8 if it is totally unuseable? Flare is a problem hood or no hood. And the pics seem to have a decidedly warm hue.

Strengths:

I don't know if you would call this a strength but it is cheap. Look cool though.

Weaknesses:

All of the glass in it. There are many acceptable inexpensive lenses out there that produce very good results... this isn't one of them.

Similar Products Used:

28-90 3.5-5.6 Quantaray "sorry I sold it" 28-80 2.8-4L Canon 35mm 2.0 Canon

Customer Service:

Didn't use it.

Review 5 of 8

Price Paid:  $0.00 from Saudi Arabia

Summary:

This is a good lens for those starting out in photography. The max aperture of 2.8-4 gives it a slight edge over the Nikon 28-80 3.5-5.6g in low light. Sharpest at 5.6 @ 50mm. Ideal for going places where you are likely to damage it, as it is priced so low you can easily get a replacement. ;-)

Strengths:

Price and small size.

Weaknesses:

Could be sharper at the 28mm end.

Customer Service:

They actually reply to emails. :-)
