Sigma lens <---> D30

[mknodpipe]

Hi folks,

I've got a Sigma 28-300 Asph. Macro Lens. Bought it brand new. It seems to have a problem functioning
on my D30. The pics often just don't turn out sharp.
I was wondering if the lens itself had such bad optics or
if it just ain't adjusted properly in order to work with the D30. Should I sell it and buy a Canon lens?

sorry, it's a 28-200mm!

A lot of people on this forum would say get a Canon.

I think though that the Sigma is a fine lens. (I've used the 28-200 on my 10D and was very pleased with it)

Can you borrow another lens to see how that performs. It is possible to get a bad one. You may even be able to bring the lens to the store and swap it for another of the same and see how that turns out.

thanks for your reply cyberdyne. btw., wonderful website and beaut pics!!

Thanks :)

..and your welcome :)

By the way,.. all the photos on my site were taken with the 10D and Sigma lenses... I was going to try and buy all Canon,. but so far the three lenses I have ended up Sigmas.

28-300mm (was 28-200mm, but I "upgraded") for the record I think the 28-200 was little better.
70-200mm
50-500mm

i'm thinking of buying the sigma 28-70 F2.8. good lens?

i'd buy the 50-500 but too big and too expensive.

ive got the sigma 24-70 2.8 and i like it. good focal range and fast aperture. focuses well and produces sharp pics.

i have sima 24-70, 50mm macro, and 70-200 apo maco with my d60 and i enjoy with them
canon lens are too expensive for non professional use

good thing you're satisfied with your sigma products. i have a sigma EF 500 Super flash. Seems to be alright up to now. But i am not sure if i will ever buy a sigma lens again... i've tested a sigma sa-7 as well and was not blown away at all. really not bad, but can't compete with
nikon or canon bodies.

my bro used to have a sigma sa 500 slr with two pretty expensive apo lenses. one of the lenses had dirt between the two front glasses and the camera produced
lots of blurry images - maybe due to the crappy autofocus.

all in all, to me, sigma doesn't have a good quality control... and the products aren't convincing.
