Sigma 150-500mm f/5-6.3 AF APO DG OS

Review Date: Jul 6, 2009 Recommend? yes | Price paid: Not Indicated | Rating: 9 

Pros: Build quality, Price, IQ, weight, focussing, with crop 750mm on D300
OS is a bit noisy, with lenscap and fully extended very long. with crop 225mm on D300 (not a very big issue since I wanted long range)

I bought this lens an couple of months back because I wanted more range on my D300.
But, since I do not use it on a regular base I looked with a max budget in mind.
I've read a lot of reviews before choosing this lens and can now say that this lens is great! Image quality, focussing, weight are all very good.
At a little under 2 kilo's it is definitly not a real heavyweight, but after a couple of hours in the field you will notice it ;-)
After a few months I'm still very happy with it!
On my D300 focussing is fast and accurate, even in less than perfect light.
Pictures have good colour and contrast.
The OS works fine but is a bit noisy and seems to start a bit slow before realy stabilising the image, but thats also getting to know the lens and working with it I suppose.
I've also used it on my old Nikon F80 and it works great too allthough the combination was a bit front heavy. the positives coming out of the camera also were sharp with good contrast and very colourfull.
In my opinion this lens is a good choise for those looking for range and are on a budget.
Always check your lens when buying, QC from Sigma has improved a lot but still isn't perfect!!

Sigma 17-70mm F2.8-4.5 DC MACRO

Review Date: Jul 5, 2009 Recommend? yes | Price paid: Not Indicated | Rating: 8 

Pros: PRICE!, HSM, image quality color/sharpness, weight, feels good, range
Build quality not EX, extends a lot from 17 to 70mm (dust problem?), not f2.8 all the way

I bought this lens june 2009 and I almost immediately loved it.
I know it's a budget lens but when using it, it feels nicely solid (though buildquality is not EX).
On my D300 the new HSM focussing is fast and very quiet.
allready at f2.8 the pictures are colorfull and have very good sharpness and sharpness gets even better when stopped down.
To bad it isn't 2.8 all the way, but then again the price..........
the zoom and focus rings are very close to each other so watch your fingers.
It extends a lot when zooming, I hope the dust stays out.
I have some differculty with the very subtle manual focus, probably some getting used to on my part.
The macro is a nice bonus and works ok.
At 269 Euro's (approx 370 US dollars) new, it's an absolute bargain.
When people see pictures taken with this lens they do not believe it's a budget lens (I like that!).
To me it's a great walkaround lens.
