(reposted to proper forum)

I'm new on this forum so hi to everybody. I'd like to share with yo
all opinions and experiences within this world so I hope we can hel
each other.

My doubt is the following: I recently bought a SLR digital camer
(minolta 7D) so I intend to buy quality lenses for it. My idea is t
cover the 28-150 (at least) range (if we consider the 1.5 crop factor
with two lenses.

Everybody agrees that new sigma 18-50 f 2.8 is a superb lens so I jus
need a lens to cover the rest of the range. I heard many good thing
about tamron sp 24-135 3.5-4.5 and 28-105 f2.8: my concern is how thi
lenses would perform when attached to a digital camera in terms o
sharpness, contrast, color rendition, etc.

I'd very appreciate your opinion about these lenses or any othe
suggested to use in a SLR digital camera.

Raúl
