Another victim of the autofocus problem
I am another one of the customers that is having trouble with this lens and the autofocus on a Digital Rebel XT.It locks focus less than 50% of the time.My other Canon lenses don't have this problem.

Focus problem not found
I just purchased the Sigma 30mm f/1.4 to use on my Canon 20D and XT 350. I shot several low light close ups and found it is spot on for focus.

More Focusing Problems
I bought this lens for my rebel xt for low-light indoor situations, but soon discovered that it was not focusing correctly at wide apertures. I thought it might be a depth of field issue or that somehow I was making the mistake with the camera. I even adjusted the AF to focus only on the center point and continued getting fuzzy pictures.

Useful lens
It is what you would expect for a lens in this price range. It is a perfect everyday lens especially well suited to photograph outdoor events where there is close and far action. It is made of light plastic which makes it easy to carry but I would not want to drop it - especially when extended to 300mm. Overall I am very satisfied with my purchase.
I like this lens
I like this lens - even though I don't find myself using it as much as I did for awhile. My Nikon 18-200VR has replaced the usefulness of this lens, especially since upgrading to the D200 where the 10 megapixels allow you to zoom to the 200 point and then crop. Still, this is a solid lens, it has a nice size and weight, and the focal range is terrific. No problems noted at either the 28 or 300 focal points, but sharpest image is between 100 and 200. Slight corner fringing at 300, but similar to that of the Nikkor 70-300, so I can't really complain. A good lens at a fantastic price. This hasn't caught on as much with Nikon users as it seems to have gone over like wildfire with the Canon crowd. Recommended. ... Read more

A good piece overall....
I purchased a Nikon D70S in August and decided on the Sigma 18-200mm lens instead of the 18-35mm Nikkor kit lens. It really boils down to how one uses this lens as to whether you like it or not. With the 1.5 conversion factor of the D70S, this lens operates as a 27-300mm. I do an ocassional wedding and senior photos throughout the year but I shoot more landscape/nature photography than anything. Unless a person requires a super fast lens, this piece does a very good job overall for the price. Since the majority of my work is off a tripod, the 3.5 max aperture has not been a problem even in very low light situations. Since it's the only Nikon based lens I own, its like having several lenses in one and I never have to worry about dust getting on the sensor during lens changes.
Faulty lens?
Left side of all pictures was soft compared to right side, especially the lower left portion. Exchanged for a replacement. ... Read more

Pretty nice flash unit...Photos uploaded today
Hard to believe you don't see the rear panel when looking around for this unit.. thought I better upload some.
Perfect despite one or two little quibbles
I used to own the Canon Speedlite 420EX which I used to great effect with a Canon G5.When I upgraded to a Digital Rebel 300D I lost the ability to manually adjust the 420EX because neither it nor the Rebel has flash compensation.Hence I bought this Sigma flash for the ability to manually adjust flash output.
A photo-newb's first flash unit...
Recommend this unit vs. the 420EX b/c of its features and price range.Note: it doesn't have a lock for 45degree angle, only 90, 75, 60, and 0. ... Read more

Good Lens for the Price
I have a Nikon D70 Kit, This Lens is very fast for outside shot. Focus quick and the color is very accurate. I'm very please with this lens , even the macro is very good.I highly recommend this one.

Best telephoto lens for the price
You can't go out and spend around $200 for a telephoto lens and expect it to perform like a $700 or $1300 lens, not going to happen. I think for the price range its a great addition, especially with the useful macro capibilities. Sure its not as fast of a focuser as Nikon's AF-S lenses, but it's also about 1/3 the price. The sharpest point for this lens is 70-220 at F/8, but thats not saying that the pictures are otherwsie unusable. As for indoor use, you need a flash. As mentioned before it really is too slow to use indoors (thats what primes are for anyways) but for the price, quality of the image, its a no brainer to pick it up

Light hungry
Reasonably good build and functionality.This lens needs LOTS of light.It's virtually useless indoors.Works well outside on bright days.I like the macro function.If I were to do it again, I probably would not buy this lens.I'm using it on a D70 ... Read more

Great value in a very versatile lens!
This lens (28-70mm) has been on my Nikon D50 camera most of the time since purchasing it, even though I have 2 other lenses (50mm and 70-300mm Nikkor).This (Sigma) lens is a full stop faster than the Nikon equivalent (and it is less costly!).It comes with a cool looking lens hood that has a bayonet style fitting to the lens. I rated this 5 stars because it is a great value.I highly recommend this lens for someone who wants to take good pictures and doesn't want to spend a small fortune on a lens.Great value! ...

The Sigma APO Teleconverter 2x EX DG for Canon Digital SLR Cameras is a dedicated APO teleconverter that can be mounted between select lenses and the camera body to increase the focal length by the power of two. The multi-layer coating reduces flare and ghosting, which is a common problem with digital cameras. The lens also offers maximum magnification without any variation in the minimum focusing distance. Compact and lightweight, this teleconverter can convert your lenses into longer focal-length lenses, so you don't have to do a lot of unnecessary footwork. A case for the lens is included. ...

Pretty good lens
I bought this lens with my Canon Rebel XTi. The default lens that came with the camera was very bad (EF-S 18-55mm f3.5-5.6). I don't recommend it to anyone, it is really a waste of the camera's capabilities, and the pictures you get may not be as good as that from a point and shoot camera.
Wrong product description
The product review given for the Sigma 18-55mm lens actually describes the Sigma 50mm macro lens. I don't think the 18-55m lens will focus to 1:1. Amazon needs to correct this listing.

Great lens with minor problems
I am very happy with my purchase of this lens.I bought it to replace my Rebel XT's 18-55mm kit lens, and it compliments the camera very well.The greatest strength of this lens is its remarkable sharpness.Even 100% crops retain their quality.Shots are even acceptable at f2.8 (better than or equal to the kit lens at f8+), and past f8 the lens is stunningly sharp.I uploaded some shots and 100% crops to amazon in order to illustrate my point.The sharpness of this lens is easily comparable to Canon's 17-40, which says quite a lot.

Sigma EF 500 DG Flash
I was looking for a Minolta flash but after reading about the Sigma I decided to give it a try.It was about 1/2 the price the Minolta and had more power.I like the way the flash sinks its zoom setting to my camera's zoom lens.The wireless feature is easy to use and gives a person quite a bit of flexibilty with lighting the subject.I'm still learning but so far the flash has done everything I expected. ...
