Great lens
I found that Sigma 15 mm & 20 mm lenses great. Put on my Nikon D100, I can always take picture on every light condition. Especially in shady places where I set the ASA 800 - 1000, this would create a wide depth of field. Read more

Good lens at a great price
I was searching for an inexpensive but fast 24mm or 28mm wide angle lens primarily for shots of the night sky when I found this. For about $85 including shipping, this lens turned out to be much better than the standard Canon kit lens -- sharper, working better in low light conditions and giving you a wider field of view. And this is much cheaper than a 28mm prime lens. I've gotten some fairly sharp photos from this lens and was surprised to find it allows moderately fast auto-focusing in even dim lighting. The lens also allows you to get within two feet of the subject.

EM 140 DG
Finally a flash Nikon should have produced long ago. I shoot a lot of macro and have used the Nikon SB 29s with my Nikon D100. Unfirtunately that flash forced me to use manual mode as it doesn't know about digital camears. This is fine most of the time, but sometimes you don't have the time to experiment and shoot bracketed series, etc. So I went out and bought this flash.
Sigma EM 140 DG-worth a try
I have been searching the net for a reveiw of this flash. Since I couldn't find one I just went out and purchased one. Yes this flash works iTTL on a D70. I would have given it 5 stars if it had a more robust hot shoe like the SB 600 or DX 50 both Nikon flashes I own. (I have a Nikon SB 21 and it's hot shoe has worn out being the all plastic as well) . Other than this negative this product seems very well built and sturdy. The flash is permanently attached to the control head unlike the Nikon ring flash which was in 2 parts. This makes stowage a litte difficult in your camera bag however it does come supplied with it's own very nice ballastic nylon bag. Unlike the Nikon the cable is spring coiled and always stays neatlyout of the way. It is a good sturdy and well reinforced cable. It's controls are fairly simple to figure out.took some pictures today of orchids and the exposures were (mostly)perfect. I put my camera on the full PHD mode (push here dummy) and the EM 140 DG on iTTL and shot away. Most of the shots were perfectly illuminated. I then switched to A mode that the instruction booklet tells you to use when shooting macro distances. In this mode I was able to set the bracket mode to vary the flash and it worked like a charm . In all cases the middle shot was the best . Battery life was good I took over 70 shots today and the recycle time was still very rapid. I am in no means an expert on either the D70 or photography in general. I also tried the manual mode with both flash and camera and was able to experiment to get stunning results. Sometimes you want the background to be blacked out and you need full manual. You can also vary the output independetly of both sides.In manual its easyto shoot and check results in the display. You have to love digital for this alone. I was using this flash on a 70-180mm Macro Nikon and had to get a 58mm to 62mm step up ring. It worked well and did not impede the field of view at all. Sigma supplies a 55mm and 58mm with the unit. This attachment is very well made and also much nicer than the flimsy one that Nikon supplies. You will have to go to the Sigma website to buy other sizes which I think are 62mm 72mm and 77mm. I'm very happy that I got this flash. However like any camera equipment the best test is to go buy one and try it for yourself. Good shooting.

A very good lens
I took a look a this lens almost as a fluke -- I wanted something that gave me quick speed at 2.8 but had more range than than the prime standard 50/1.8...and I was so pleased with the lens I have used it quite a bit more than I thought I would. The quality of the photos is excellent, good colors, good contrast. The lens is relatively light (less than a pound) so it "feels good" on the body. Compare this lens to the Tamron 17-50/2.8They are virtually identical. This is a supurb replacement for your standard kit lens.

Nice Lens!
I use this lens on my Nikon D70. It's great. Before I bought it, I thought I should get a lens with better range, example, the Nikon 18-200mm lens. My friend had told me about this one, so I decided to buy it for the heckuvit. I was glad I did. The range isn't a big deal now, but the only problem is--umm--uhh--I can't really think of any problems I've had with this lens, besides the fact that I all of my lenses, I use this one the most, and I paid all that money for the other lenses! Trust me, it's great. ... Read more

Fast Focus, Very Sharp Lens
I've had this lens about two weeks, using it on a Canon 30D. It seems to be very sharp at all focal lengths and f-stops. Focus is very fast with Sigma's HSM (Hyper Sonic Focus Motor). It's for APS-C sensor digital cameras only, which enables it to be shorter, but once sensors are all full-frame you'll be sorry you got a DC series lens. The Sigma 70-200 f2.8 is full-frame, but more expensive and much longer.

Worth every penny
I've been using this lens for about 3 months now on a Canon EOS-350D and the Canon 5D.It has supurb optics.At f2.8, it is sharp.From f3.0 it takes off and stays sharp up to about f14.The focus mechanism is a little different from most other lenses, but actually I've grown to like it.With a push-pull lock at the end of the lens for manual-auto focus, you can put this thing in manual mode two different ways.If you're focusing in, pull the mechanism and you don't have to worry about the camera trying to change focus and you don't have to take your hand off the lens to find the manual button.Really cool actually, just a little different at first.It is light enough that weight has never been an issue, though it does extend out pretty far when focusing.Focus speed is not as fast and there is a little more motor noise, but this too is never an issue as all my close work is manual focus.As a telephoto, it works very well, but the autofocus speed comes into play here.It will hunt in some conditions as a telephoto, but it is pretty accurate.
Quirky, but worth it
When I first started looking for a mid-level macro lens, a few weeks ago, I was naturally drawn first to the Canon 60mm, as I have already have 2 Canon bodies.

You get what you pay for
I have used a number of Sigma lenses throughout the years and I have been quite satisfied.I have a 28 - 300mm lens that I used with my 35mm Canon A2e. A few years ago when I made the switch to digital, I called Sigma and for around $75, they converted the lens to work with my new digital equipment. I have 3 Sigma lenses that I use now.I have had the 18-50mm less than a year and it takes great photos, HOWEVER, when you twist the lens hood off and on the lens, it turns the focusing gear.Mine has stripped out and you can hear gears grinding as the camera tries to focus.Somehow it does still manage to focus but it is slower and quite noisy. I know it is only a matter of time before it stops working altogether. I have replaced this lens with another Sigma, but I chose a higher end model with internal focusing. The 18-50mm would be a great lens at a great price for the occasional user if much care is taken with the hood.

Entirely satisfied
Inexpensive entry-level short zoom.Good value for the money, especially if you don't have anything to cover this focal range.Build quality seems a half-notch above the standard Rebel XT kit lens. ... Read more

Good for the money, pros back away.
I've used this lens a couple of years now. It's a good value but not up to professional standards.
Professional Quality Optics
I have owned and used this lens professionally for over a year now and after a minor focus issue that was resolved very quickly by Sigma's excellent service department I have to say this is the sharpest 24-70 lens I have used. I also have experience with the canon 24-70L lens which retails for just over a grand and the Sigma is sharper throughout the whole range(even at 2.8). The only negative thing I have to say about this lens is the noisy autofocus (Canon's USM is much quieter). But it is still reasonably fast to AF. This is definately the best lens for the money in this zoom range and is without a doubt the best optically. Canon's build quality and weather sealing are definately superior to the Sigma so if that is an issue, you may want to go with the Canon.
Some Pros, Some Cons
After using my stock kit lens, 18-55, for months, I decided I really needed a new lens to replace the kit lens.

AWESOME LENS!
This lens is fast and extremely sharp. I am using it on a D200 and it is great. I am deployed in Iraq and this lens is one I can feel comfortable about walking around with. It's built like a tank. It accepts the teleconverters which makes it even better. Buy this lens from 47th St Photo. Best prices.

Excellent Macro despite limitations
I had a Canon 100mm f2.8 Macro and it was working quite well for me but I longed for a little more working distance. When Sigma came out with the 150mm f2.8 Macro, I tried researching it but couldn't find much info because it was such a new lens, I found the MTF charts on the Sigma Website and it was amazing. This lens was very close to the performance of the Sigma 180mm macro and Canon's famed 180mm f3.5 L. So I went ahead and bought it. It was a little pricy but I thought I could always return it if I didn't like it.
