Ultra-wide lens with sharpest optics!
Sigma 20mm EX is an exceptionally well made lens. Performance is extremely satisfactory. It is almost indispensable for me to go without it when I am outdoors. Takes very good wide angle shots of buildings, parks and friends and family picnicking in the park. Shots have come very sharp and crisp with edge to edge brightness and sharpness. 20mm wide angle focal length gives you a very large depth of field which is essential for taking shots of wide open outdoors, filling your frame with a large expanse of ground/sky. Fast f1.8 aperture will let you take snaps indoors in natural light and hand-held shots of lighted buildings etc. in night time. Rear focusing feature of this lens results in fast AF and also the length of the lens remains same. Macro shots of subjects will give you convex mirror type of fascinating images and one can produce far more interesting effects depending on one's creativity.

Indoor flash photography may give rise to vignetting due to ultra wide nature of the lens as most flashes cover only 28mm span. This may probably be solved by using a wide angle attachment on the flash which to my disappointment was not available for my flash (Pentax AF-280T). Also 82mm filters may prove to be expensive. But I think a filter is essential for this lens as the front element glass is very near to the filter area.

All said this is an extremely satisfying buy (most bang for bucks) which gives you great results. ... Read more

Versatile all-in-one lens with good sharpness.
This is aspherical zoom lens is a 2 in 1 zoom lens taking care of 28-70mm and 70-210mm zoom lens so no more lens changing hassles.

The results from this lens has come out very well and the crispness, clarity, exposure and sharpness are quite satisfying.

It's quite compact and lightweight but not as light as the Tamron's 28-200mm. But then I guess weight does add sturdiness and strength to a product.

It's got a very good aperture range of 3.5-5.6 for such a huge focal range. The aspherical design has added to it's compactness. Due to the non-rotating filter mount, using of polarizers has become easier.

On the downside the depth of field is the only casualty in the mid to tele range compared to smaller range zooms. ... Read more

The BEST standard zoom lens you can buy!
It as sharp as any prime at any focus length.
It smooth and perfectly lies in the hand.
It exhibit the BEST optical performance you can imagine.
It is HIGH resolution lens, it is of imperative for digital photography.
It looks cool and perfect cosmetically! :-)
It is durable one!
BTW, take EX 82-mm UV multicoated Sigma filters! They are the best I ever seen in my life! No seriously, Heliopan, Hoya, Tiffen all of them could not handle candle for Sigma in this regard! ... Read more

Incredible buy!
Performance:
This lens couldn't be much sharper at 15mm, it is pristine. Softer at 30mm, though still better than average corner to corner. I like that it seems optimized for 15mm. Very impressive, Sigma. Some flare, but any 15mm zoom is really prone to that. f3.5 is a little slow, but at 15mm 1/15 sec works for handholding, so it isn't a problem. Incredibly deep DOF at 15mm, makes for spectacular foregrounds, sharp from your feet to the horizon (at least with a cropping DSLR). 8 blades is very respectable for a lens of this price and not much is usually OOF.

Build:
Superior. Suprisingly light for it's size. Fast AF. The 82mm front thread is accomplished using a felt lined cap that slides firmly over the permanent pedal hood. A little awkward but it works a lot better than it sounds. No vignetting with an 82mm front filter using a cropping DSLR at 15mm, I doubt the same would be true with full frame where the angle of view is really uncanny.

Overall:
Arguably the best in its class, great price makes it even better. Everytime I see the images I thank myself for buying this lens. ... Read more

Great quality and easy to use controls
Sigma has a winner with the Foveon chip. Excellent images and far superior to ordinary chip cameras. The best feature of the camera itself, in my opinion, is the ease to which to operate the controls. The controls are very intuitive compared to the other 4 or 5 digitals I have owned or operated. Simplicity is the secret, not a lot of "junk" that will never or rarely be used. I was a professional photographer in the 80's and 90's and always found other digitals too complex even for someone with a comfortable knowledge of photography. The only negative I have found in the month and half I have owned the SD-10 is battery usage. You have the option of using rechargable AA or the CRV-3 batteries. With the AA, I get intermittent operation, something Sigma stated was characteristic of Metal Hydride batteries, especially if new. I'm a little skeptical of that assessment. I did just purchase the CRV batteries to try them. The only other issue I have is that I try to use the camera in a professional setting and there is not a way to get the flash off the camera. I purchase the Sigma DG 500 Super, which is a great flash if you don't need it off the camera. I bought the pc adapter and use it with a Metz 60ct2 flash. It would be nice if they (or someone) would produce a TTL cable or compatable flash. Overall I'm very happy with the camera and hope that more compatable accessories follow.

A great camera with a few drawbacks
Perhaps the most annoying thing about using the SD10 is that there is no straightforward answer to the seemingly simple question, "How many megapixels?" Purists claim that it has only 3.4, and Sigma claims 10.2, counting all three colors at each of the 3.4M locations. When people ask (and when they see my prints, they DO ask), I sometimes just say 3.4, leaving them to wonder how I do it. The way I figure, when you save the file at double size, you're getting 13.7 megapixels with the same amount of interpolation on the red and blue channels as a normal camera, and more interpolation on the green channel. However you figure, the resolution is stunning, and with a little care you can make 12" by 18" prints that are as sharp as most eyes can tell.

Pros:

1. The software, especially the "fill light" function will let you quickly massage even your badly exposed pictures.

2. The great resolution.

Cons (I'm spending more space on these because Sigma's text waxes eloquent on most the pros (and they're not lying)):

1. The software. The SD10's only format is a proprietary RAW format, so you need to run everything through their raw converter before you do anything else with it.

2. The kit lenses are OK, but not great. The 18-50 in particular is vulnerable to a lot of chromatic aberration. If you're going to shoot with EX-series lenses (and you really should), you might as well just buy the body.

3. Low light performance is not stellar. ISO 800 is practically unusable, and ISO 400 is dicey.

4. The buffer is not huge, and the write speed is slow. The camera will take only 6 high-resolution shots in burst mode, and after that it can take more than a minute for the camera to recover.

All in all, however, this is a great camera, and if you get it you're likely to one-up all those folks buying digital rebels.

An Amazing Camera
First off I want to say this is an Amazing Digital SLR.. the picture quality is outstanding.. if your in the market for a pro level digital slr you can't go wrong especially with the 2 lenses that were designed for this camera..

On another note.. amazon's features list is wrong.. the camera doesn't accept xd memory and it doesn't come with a 32 meg card.. its a compact flash format camera.. i'd recommend a 512 meg or higher CF card as it fills up quickly at its highest resolution.. my old 64 meg CF card can take about 6 pictures on its highest resolution.. i've ordered a 1 gig card i'm just waiting for it to ship now.. ...
