Pros: A great everyday lens.
Cons:
A little noisy AF.

I finally bought this lens used in excel condition like new for 100usd, to use on my Sony A100, with my Sony this lens will be come optical image stabilizer at all time, thats the best avantage to own Sony dslr, the lens is well built, made in Japan, small and light weigh, focus is exceptional fast, but a little noisy, filter size at 62mm, comes with matching petal hood, i tested shot it about 300 shots by now, i can see that at wide angle @18mm images are good, sharpness is fine, nice contrast, but from 35-125mm images are even sharper, images turn out great, good detail contrast and nice colors, now! im not sure its from the lens or camera, or both, but im very happy with it..
I am sorry for those whos wrote neg reviews on this Sigma lens, either he or she got a bad copy or the camera body, or dont know how to use it right?, buy Sony camera body or Fujis then you will be alright, i havent had a bad lens to use with my Sony at all. Infact, i have sold all my Nikon and Canon lenses to stick with Sigmas and Tamrons, im not saying Sigma is better lenses, im saying that Sigma is a better buy ( Sigma is the biggest camera lens maker factory in the world)i trust them and like them, the other lenses are over price and you cant really tell the diff in image quality in everyday use.
With this range 18-125mm you can really use it at all time..i like Sigma choice in lens ranges, they do make all diff ranges, i used to carried 2 lenses on vac, now i can use only 1 lens.
Happy camper!

Pros: A great tele lens, extremely sharp.very quiet.good strong contrast.
Cons:
none found..

I have great experience with many Sigma EX lenses, so to get this Sigma 70-200mm EX HSM F2.8, i have no doubt that it will produces great image quality, indeed its razor sharp lens. Its not to my surprise that it will, it has a beautiful petal hood, good size but not too heavy, HSM is very quiet, most of the time i dont even hear AF, it produces very contrasty, strong colors and razor cutting edge sharp. I use it with my 2 Fuji S2 & S3 pros and Nikon d50, with Sigma EX lenses and Fujis super CCD i get best pictures quality, today i dont think any DSLR can out do this combinations.
Im very happy with all Sigma EX lenses i got. with this said, ive sold all my Canon and Nikon gears to keep FUJI and Sigmas.
Sigma is the biggest lens company maker in this world..the name to trust.

Pros: A good lens
Cons:
Cheapy made in Thailand with plastic rear mount.

I bought this lens to try out, after 3 weeks and shot over 500 shots, i sold it, it just a cheaper version Nikon made, i wasnt so thrilled with it. The sharpness is average, nothing to talk about. Soft at both ends.
I replaced it with Sigma 28-200mm a much better choice , Sigma is a better lens in overall quality and performance.

Pros: Very sharp lens
Cons:
none really.

I got this lens for 85$, used it on my Sony A100, oh!, its so sharp at all ranges, a very good buy..Im very happy with it..If your copy is not sharp then you should buy Sony A100 with Anti shake in body.

Pros: Very sharp lens.
Cons:
Wish it was F2.8

I finally bought this lens, im so thrilled with it, i use it with my Fuji S3 pro, images are very sharp at all ranges,i shot about 350 shots on Vegas trip, mostly at night on tripod, all came out amzingly sharp. No vergnettes, some distortion, but that can be expected on this 15mm wide. I strongly suggested.
My copy is very sharp, now!, if your copy is not, then you should buy Fuji S3 pro.

Pros: Good build, good price.
Cons:
not really a sharp lens, distortion at wide.

I got this Nikon 24-120mm non VR version. I used it for about a year on my Fuji S2 pro, i shot with this lens about 2,000 shots on the trip to Asia. After the trip i had to worked on 95% of the pictures in Fotoshop just tried to make images look sharper, i finally sold it..its not a sharp lens, slow focus, stiff focus zoom ring, hunts in dark, its an ok lens for some one who dont know any better on lenses.
I replaced it with Tamron 24-135mm a much better lens, images are very sharp, so sharp..Tamron is a better buy. one of my sharp lens.
My brother also sold his Nikon 24-120mm VR lens too, he wasnt happy with its sharpness either.
Cheers.


 
Nikon D50

Pros: Great price for a DSLR, it does the job for less cost.
Cons:
I dont think D50 has custome white balance?, if anyone know how please show me. thnxs.

To follow up with my Nikon D50 review, I got a chance to test out both of my Sony A100 vs Nikon D50, I used both with the same Tamron SP 28-105MM F2.8 (retail for 1,000$), I got 2 of this same lenses because I like it a lot, I shot both at the same cropping and subjects, both set at 200iso, both with f8.0, pretty much the same settings. It was a partly cloudy day.
My conclusion is:
Nikon D50 has a bit better in sharpness, but for that you gained abit more noise in sky or smooth surface, or in 3/4 shadow end. D50 neutral is more leanning toward reddish(pinkish) or bluish cast, the greys come out of D50 is alomost never grey, people fleshtone seem to lean toward reddish, seems to blout out highlites in the whites, D50 got nicer contrast and brighter.I like the shutter snap better on D50, both feel good in my hands, both are fast shooting, both got battery grip.
Sony A100 has less sharpness, but smoother images, the neutral is better than D50, the whites and the greys seem to be on par, but in overall images it got warmer cast to it..After all Sony made sensor (CCD) for Nikon.
Both are good, its really what you want.
I personally pick my 2 Fujis S2 & S3 PRO over these 2 cameras for its final products. Fuji has much better Dynamic range with its Super CCD, and beautiful Fuji colors.
Looking to buy Fuji S5 Pro when the price drops, and waiting to see all new Sony DSLRs coming out soon.
